VOX SAYS
Mainstream Democrats shouldn’t fear Bernie Sanders

He’d be a strong nominee and a solid president.

Sen. Bernie Sanders’s win in New Hampshire following his quasi-win in Iowa dashes the Democratic Party establishment’s big hope of the past four years — that he’d just fade away.

Alarm, clearly visible in a range of mainstream Democratic circles over the past several weeks, is now going to kick into overdrive.

But this frame of mind is fundamentally misguided. For all the agita around his all-or-nothing rhetoric, his behavior as a longtime member of Congress (and before that as a mayor) suggests a much more pragmatic approach to actual legislating than some of the wilder “political revolution” rhetoric would suggest.

On the vast majority of issues, a Sanders administration would deliver pretty much the same policy outcomes as any other Democrat. The two biggest exceptions to this, foreign policy and monetary policy, happen to be where Sanders takes issue with an entrenched conventional wisdom that is deeply problematic.

Some of the anti-Sanders sentiment is driven by pique at his followers’ most obnoxious behavior. But it would be better to bring these voters into the tent than leave them outside attacking inward.

Sanders winning the popular vote in the Iowa caucuses is hardly the end of the 2020 Democratic primary. Joe Biden remains a formidable contender; there are many delegate-rich states with larger African American populations that should be more favorable to him, and it’s been known for a long time that the idiosyncrasies of the caucus structure give Sanders an edge he won’t have in future primaries.

And, obviously, nominating a 78-year-old self-described socialist is a risky move and not an outcome that would have been cooked up by political scientists working in an electability lab. But at this point, all the main contenders have some electability risks. Sanders comes with a strong electoral track record in practice, and he brings some unique assets to the table as someone who appeals precisely to the most fractious elements of the anti-Trump coalition.
Sanders has a strong electoral track record

The specter of “socialism” hangs over the Sanders campaign, terrifying mainstream Democrats with the reality that when asked about it by pollsters, most Americans reject the idea. Given that Sanders himself tends to anchor his politics in Franklin Delano Roosevelt and the New Deal, it seems as though everyone involved would be better off if he labeled himself a New Deal Democrat and let us revert to the normal pattern where Republicans call mainstream liberals “socialists” and liberals push back rather than accepting an unpopular label.


All that said, in current head-to-head polling matchups with Donald Trump, Sanders does well and is normally winning. Skeptics worry whether that lead will hold up against the sure-to-come cavalcade of attack ads from Trump. It’s a reasonable concern.

But it’s worth underscoring that Sanders’s actual electoral track record in Vermont is strong. Winning elections in Vermont is not, per se, incredibly impressive. There are plenty of left-wing Democrats who win elections while underperforming simply because they run in such blue states (Elizabeth Warren fits that mold), as well as plenty of moderate Democrats who overperform in tough races even while losing (former Missouri Sen. Claire McCaskill is a good example).

Sanders, however, overperforms in his easy races. He consistently runs ahead of Democratic presidential nominees in his home state, which suggests he knows how to overcome the “socialist” label, get people to vote for him despite some eccentricities, and even peel off some Republican votes.

He first got to Congress by winning a tough three-way race in 1990, when Vermont was an only slightly blue-leaning state. He went on to consistently run ahead of Democratic presidential campaigns as a candidate for Vermont’s at-large seat in the US House of Representatives.
In 1992, Sanders got 58 percent to Bill Clinton’s 46 percent (it was a strong state for presidential candidate Ross Perot, but Sanders also faced a “third-party” challenge from a Democrat).
In 1996, Sanders got 55 percent to Clinton’s 53 percent.
In 2000, he got 69 percent to Al Gore’s 51 percent.
In 2004, he got 67 percent to John Kerry’s 59 percent.
Sanders got elected to the Senate in 2006, so he wasn’t on the ballot in 2008 or 2016. But in 2012, he won 71 percent to Obama’s 67 percent.

This is not definitive proof of Sanders’s skills. But it would have been easy for Vermonters who had doubts about Sanders to cast meaningless protest votes for his opponents.

Instead, Sanders appears to be able to make lemonade out of the whole “not officially a Democrat” thing by getting the votes of some non-Republicans who backed Perot in the 1990s and, more recently, other third-party candidates such as Jill Stein, Ralph Nader, and Gary Johnson. Indeed, one noteworthy thing about Sanders is that in head-to-head polling matchups against Trump, he tends to do better than you’d expect simply by looking at his favorable ratings.

And, critically, Sanders’s popularity seems to be concentrated among certain blocks of persuadable voters (likely those considering a third-party vote), while a chunk of those who disapprove of Sanders are hardcore partisan Democrats who don’t like his lack of party spirit but will vote for him anyway.
Sanders knows how to govern effectively

Mainstream Democrats also worry at times that Sanders would simply prove too extreme to get things done as president. And, indeed, on occasion his campaign lapses into rhetoric that suggests an unreasonable aversion to compromise.



There is no “middle ground” when it comes to climate policy. If we don't commit to fully transforming our energy system away from fossil fuels, we will doom future generations. Fighting climate change must be our priority, whether fossil fuel billionaires like it or not.— Bernie Sanders (@BernieSanders) May 10, 2019

But it’s worth remembering that Sanders is a 30-year veteran of the US Congress, not a 20-something hardliner with a red rose on his Twitter bio. We can evaluate his actual track record as a politician.

In that capacity, Sanders has sometimes staked out lonely, courageous stands (against the Iraq War or the Defense of Marriage Act, which barred same-sex couples from enjoying the same federal benefits as married couples). He’s also frequently cast meaningless protest votes against big bipartisan compromises that sail through with huge majorities. But he’s never pulled a Freedom Caucus-type stunt and refused to cast a pragmatic vote in favor of half a loaf.


Sanders has always talked about his blue-sky political ideals as something he believed in passionately, but he separated that idealism from his practical legislative work, which was grounded in vote counts. He voted for President Barack Obama’s Children’s Health Insurance Program reauthorization bill in 2009, and again for the Affordable Care Act in 2010. He voted for the Dodd-Frank bill and every other contentious piece of Obama-era legislation.

Indeed, this has been somewhat forgotten in the wake of the 2016 primary campaign: While Obama was in the White House, it was Sen. Elizabeth Warren who attracted the ire of administration officials and congressional leaders by occasionally spiking executive branch nominees or blowing up bipartisan deals.

The policy area in which Sanders has had the most practical influence is veterans-related issues, as he chaired the Senate Veterans’ Affairs Committee for a two-year span, during which Congress enacted substantive reform to the veterans’ health system.

Given the objective constellation of political forces at the time, this required bipartisan support, so Sanders (working mainly with Republican Sen. John McCain) produced a bipartisan bill that, in exchange for a substantial boost in funding, made some concessions to conservatives in creating “private options” for veterans to seek care outside of the publicly run Department of Veterans Affairs.

It’s fine if you want to be annoyed that Sanders’s self-presentation as a revolutionary who will sweep all practical obstacles aside is at odds with his reality as an experienced legislator who does typical senator stuff in a typical way. But there’s no reason to be worried that Sanders is a deluded radical who doesn’t understand how the government works.
Sanders’s annoying fans count in his favor

One of the odd developments of the social media era is that the extremely online set — which is not most people but does include a huge number of journalists, think tankers, activists, and other influential people — reacts as much to their perceptions of different candidates’ support bases as to the candidates themselves.

MSNBC host Joy Reid, for example, is a frequent Bernieworld antagonist and over the weekend posted a poll showing that Sanders fans were much less likely than Biden or Warren supporters to commit to backing the eventual nominee come what may.



Poll: Will you support the Democratic nominee even if it is not your candidate? #AMJoy pic.twitter.com/Cb1IwxadLT— AM Joy w/Joy Reid (@amjoyshow) February 1, 2020

Her followers, in turn, reacted by castigating Sanders voters as “useless” and “a cult-like following,” while one observed this “looks bad for Sanders.”

John Weaver, one of the leading Never Trump ex-Republican personalities, sniffed, “one of them isn’t a Democrat.”



One of them isn't a Democrat— John Weaver (@jwgop) February 2, 2020

It is all well and good to be annoyed by people who will not commit to voting Trump out of office regardless of the identity of the Democratic Party nominee. But if you are a person who worries about electability, which many highly partisan Democrats are, then you are by definition a person who worries about courting the votes of people who will not commit to voting Trump out of office regardless of the identity of the Democratic Party nominee. The fact that Sanders has unusually strong support among people like that is a strength of his campaign, not a weakness.


Whenever I make this point, mainstream Democrats get grouchy and start grumbling about how you don’t negotiate with terrorists or give in to your toddler when he’s throwing a fit.

Those are funny analogies, but any effort to court swing voters has that same basic structure. Party loyalists are asked to make concessions to the views of people who are not loyalists, precisely because the non-loyalists’ irresponsibility and flightiness gives them more objective leverage. But if you pull it off successfully, what party loyalists get in exchange is partisan electoral victories — exactly the thing that, by definition, is most important to party loyalists.

If you’re a loyalist, it’s natural to feel grumpy about the non-loyalists who love Sanders, but if you’re trying to win the election you need to get the votes of non-loyalists. By the same token, if you’re annoyed by Sanders’s Twitter’s attacks on mainstream Democrats, you’ll start finding them a lot less annoying if he gets the nomination and they start directing that energy against Trump and the GOP.
Sanders has some good ideas

Last but by no means least, some of Sanders’s out-of-the-mainstream ideas are good and correct.

Some of his ideas are not so good, but it’s important to understand that on the vast majority of topics, the policy outputs of a Sanders administration just wouldn’t be that different from those of a Joe Biden or Pete Buttigieg administration. Whether a new president promises continuity with Obama or a break with neoliberalism, the constraints will realistically come from Congress, where the median member is all but certain to be more conservative than anyone in the Democratic field.

On foreign policy, by contrast, the president is less constrained, and Sanders’s real desire to challenge aspects of the bipartisan foreign policy consensus makes a difference. He’s much more critical of Israel than most people in national politics, he’s a leading critic of the alliance with Saudi Arabia, and he’s generally skeptical of America’s expansive military posture.

These ideas are coded as “extreme” in Washington, where there’s significant bipartisan investment in the status quo. But polls show that most voters question the narratives of American exceptionalism, favor a reduced global military footprint and less defense spending, and are skeptical of the merits of profligate arms sales.

In practice, essentially every president ends up governing with more continuity than his campaign rhetoric suggested (Trump hasn’t broken up NATO; Obama never sat down with the leadership of Iran), so the differences are likely to be more modest than the rhetorical ones.

But differences are welcome and needed. The misbegotten invasion of Iraq should have, but largely didn’t, shake up the establishment “blob” that’s obsessed with pursuing US military hegemony and endless entanglements in the Middle East. Recent reporting by the Washington Post revealed that military and political leaders across three administrations have been lying to the public about the course of the war in Afghanistan — and it barely made a dent in domestic politics.

Nobody should have illusions about Sanders somehow unilaterally ushering in a bold new era of world peace, but he is by far the most likely person in the race to push back against expansive militarism — and that’s worth considering.

Foreign policy isn’t the only hidebound institution he is poised to shake up, either.
Pro-worker monetary policy could make a real difference

Monetary policy attracts even less attention in the primary than does foreign policy. But the Washington Post surveyed the candidates’ views on interest rates when it asked whether the Federal Reserve’s current rates are too high. The results were fascinating.


Buttigieg, Biden, and Warren all demurred, citing the dogma that the Federal Reserve should stay independent of politics (though Warren, to her credit, made a strong statement in a subsequent speech on the economy about the need to emphasize full employment).

Sanders, by contrast, offered a clear statement, saying he “disagreed with the Fed’s decision to raise interest rates in 2015-2018” because “raising rates should be done as a last resort, not to fight phantom inflation.”

Sens. Cory Booker and Michael Bennet, two minor candidates who aren’t really seen as Sanders’s fellow travelers when it comes to ideology, had somewhat similar things to say. “Historically, the Federal Reserve raises interest rates when the economy has reached full employment,” Booker said, adding that “our economy’s not there yet.”

Bennet nodded toward independence before saying that the Fed “has often fallen short of its full employment mandate, which has harmed workers, especially those trying to make ends meet.” He also said that his appointees to the Federal Reserve Board of Governors “will prioritize the employment mandate and consider every tool available to meet that mandate.”

Unfortunately, this is a niche issue many people don’t care about. Almost everyone does and should care about “the economy,” though, and the main government institution responsible for the state of “the economy” is the Fed.

What’s more, this is a particularly important issue precisely because it’s a little bit obscure. Any Democratic president’s Environmental Protection Agency director will come from the universe of “people the main environmental groups like and for whom moderate senators are willing to vote,” because that’s how politics works. But there are no strong interest groups that lobby around monetary policy.

A president who wants to install well-qualified people inclined to side with Sanders/Bennet/Booker will probably be able to do so, but a president who doesn’t care (like Obama) will probably end up appointing people whose views are all over the map (which is indeed what happened with Obama).

These aren’t the only two issues in America that matter, but they’re the main ones in which different nominees are likely to lead to different results. Almost everything that’s currently being debated, by contrast, is mostly pointless.
Stop freaking out

At the end of the day, Sanders’s record is not nearly as scary as many establishment Democrats fear. His “revolution” rhetoric doesn’t make sense to me, but he’s been an effective legislator for a long time, and he knows how to get things done — and how hard it is to get them done.

Some of his big ideas are not so hot on the merits, but it’s not worth worrying about them because the political revolution is so unrealistic. And on a couple of issues where the next president will probably have a fair amount of latitude, Sanders breaks from the pack in good ways. He’s perhaps not an ideal electability choice, but his track record on winning elections is solid and his early polling is pretty good. There’s no particular reason to think he’d be weaker than the other three top contenders, and at least some reason to think he’d be stronger.

A Sanders presidency should generate an emphasis on full employment, a tendency to shy away from launching wars, an executive branch that actually tries to enforce environmental protection and civil rights laws, and a situation in which bills that both progressives and moderates can agree on get to become law.


That’s a formula the vast majority of mainstream Democrats should be able to embrace.

Lots of moderate Democrats nonetheless find it annoying that Sanders and some of his followers are so committed to painting mainstream Democrats in such dark hues. And it is annoying! But annoying people won’t stop being annoying if he loses the nomination. If anything, they will be more annoying than ever as some refuse to get enthusiastic about the prospect of beating Trump. But if Sanders wins, partisan Democrats who just want to beat Trump will magically stop finding Sanders superfans annoying — the causes will be aligned, and the vast majority of people who want Trump out of the White House can collaborate in peace.

That leaves us where we started. The president really does have a good deal of latitude in conducting national security policy. If it’s very important to you that the US maintain a hawkish military posture in the Middle East, that’s a good reason to worry a lot about Sanders.

But most likely, a Sanders presidency will simply mean that young progressive activists are less sullen and dyspeptic about the incremental policy gains that would result from any Democrat occupying the presidency. It’ll also mean a foreign policy that errs a bit more on the side of restraint compared with what you’d get from anyone else in the field, as well as an approach to monetary policy that errs a bit more on the side of full employment. That’s a pretty good deal, and you don’t need to be a socialist to see it.

The Repeating Signals From Deep Space Are Extremely Unlikely to Be Aliens. Here's Why

The Repeating Signals From Deep Space Are Extremely Unlikely to Be Aliens. Here's Why

MICHELLE STARR
14 FEB 2020
There are many things in the Universe we are yet to understand. It's a big old machine just churning out mysteries, and we tiny specks crawling on the surface of a small blue dot are doing our darnedest to unravel them.
Recently, news emerged about one of the most tantalising mysteries. For the first time, a fast radio burst (FRB) has been detected emitting in a pattern - a 16-day cycle, with four days of intermittent bursts and 12 days of silence.
We still don't know what causes these extremely powerful, millisecond blasts of radio waves from up to billions of light-years away. Most of them haven't been detected repeating, most of them are wildly unpredictable, and only five out of over 100 have been traced to a source galaxy.
It's proven extremely tricky to find a cosmic phenomenon that fits the profile of FRBs. Violent, highly magnetised neutron stars called magnetars are pretty close, but there's some doubt as to whether they can emit the nova-scale energies detected in fast radio bursts.
But the absence of a solid explanation thus far doesn't mean we should automatically turn to aliens, as so many headlines have done. When unusual cosmic phenomena appear, rampant speculation arrives at this suggestion all too quickly.
"Invoking aliens has become too systematic, too easy, and too sensationalist a way to get the public's attention ... [It] reminds me of the way we used to invoke gods," planetary scientist and astrobiologist Charley Lineweaver of the Australian National University (ANU) told ScienceAlert.
"Instead of 'gods of the gaps' we now have 'aliens of the gaps'."

Alien communication problems

In 2017, some physicists proposed that the fast radio burst signals could be produced by radiation leaking from alien spaceship propulsion systems. Others have put forward that it could be one-way alien communication.
"My understanding is that those explanations are not excluded by the available evidence," physicist Paul Ginsparg of Cornell University, and the founder of arXiv, told ScienceAlert.
"But also that they are not required by it, in the sense that there remain equally or more plausible explanations that don't employ extraterrestrial intelligence."
One big problem for the alien idea is the variety of locations and distances involved. Of the FRBs that have been localised, some are from billions of light-years away; others are from hundreds of millions.
As astronomer Seth Shostak of the SETI Institute has noted, that alone is reason enough to discount the hypothesis that FRBs are extraterrestrial communications.
"How could aliens organise so much of the Universe to engage in broadcasting the same sort of signal?" he wrote in a blog post last year.
"There's hardly been enough time since the Big Bang to coordinate such widespread teamwork, even if you can think of a reason for it!"
For the bursts to have an artificial origin, at least 100 different alien species would have to be technologically advanced to produce such a powerful signal that it can move across space and still be detected by us.
For context, here on Earth, we only developed technology that could beam radio waves into space just around 125 years ago. That means that any radio transmission from Earth would only have travelled, at a maximum, 125 light-years. By the time the signal has propagated that far, it would have become too attenuated to be detected.
That's not to say that a more advanced civilisation couldn't produce a powerful signal... but there's another problem. All these hypothetical alien civilisations would've had to have developed their technologies at just the right time, so that all their signals are reaching Earth in the same handful of years.

Are we alone?

To date, we have had no credible evidence that there are other intelligent, advanced civilisations out there. This lack of evidence for other civilisations seems paradoxical in the context of the Drake Equation, which suggests there should be quite a few of these civilisations around.
But should there? Of all the multitudinous species on Earth, only humans have human-like intelligence. In turn, this suggests that our kind of intelligence is a very long way from inevitable.
"My reading of biological evolution on Earth is that human-like intelligence is not a convergent feature of evolution," Lineweaver told ScienceAlert.
"The bottom line to my thinking is that the best data we have (data from evolution here on Earth) strongly suggest that our closest relatives in the Universe are here on Earth."
So, there are logistical reasons to think that fast radio bursts are natural in origin. As was also eventually found with interstellar object 'Oumuamua, another target of enthusiasm for alien presence - there is actually evidence in the data that the phenomenon is a natural one.
"I think the best argument against the extraterrestrial hypothesis is that we see FRBs with all sorts of weird properties (some wide, some narrow, some polarised, others not, some have multiple pulses, some are a single pulse)," an FRB astronomer, who wished to remain anonymous for concern of being targeted by conspiracy theorists, told ScienceAlert.
"If I were designing a spacecraft propulsion system (which would be bloody good fun), I'm not sure some of those properties (e.g. changing polarisation over the pulse), would make a better spacecraft engine.
"On the other hand, we do see a similar diversity of properties in pulsars, which everyone agrees are a natural phenomenon."
This line of thinking is also supported by astronomer Andy Howell of Las Cumbres Observatory and the University of California Santa Barbara.

The value of wild ideas

All that isn't to say there's no value in considering the alien explanation. It's important for scientists to keep an open mind, to be receptive to possibilities, even if they are small ones.
Consider the cases - even though they only constitute a small percentage - of hypotheses initially derided by the scientific community, only later to be widely accepted. The existence of tectonic plates comes to mind.
Wild ideas can also help to engage the public with science; not just the discoveries themselves, but the work scientists do to present the hypothesis, provide evidence for it, and generate a theory.
And there are practical possibilities, too.
"These discussions give non-scientists an indication of the sorts of the amazing observations being made, the fun that scientists have thinking about them, and the possibilities that are out there," Ginsparg told ScienceAlert.
"Wild speculation can sometimes inform the next generation of instrumentation, which can then either confirm or refute the wild hypothesis, or see something else entirely and unexpected. And that too is what makes science fun."
The difficulty lies in understanding the difference between pondering wild ideas as a thought exercise, and evidence based on data and prior experience, observation and conclusions.
Or, as Ginsparg put it, "in a discussion about string theory, a senior physicist once argued to me that one can't 'prove' there's no Santa Claus, but we have alternative ways of explaining the observed phenomena with fewer unnecessary assumptions."
So, for now, we'll be holding off on the aliens until the aliens tell us otherwise.

A radio signal is coming from space every 16 days. What the hell is it?

Scientists don’t know what to make of fast radio bursts. Some think they come from aliens.

Fast radio bursts are one of astronomy’s tantalizing unsolved mysteries. These sudden pulses of radio waves come from far outside our galaxy. They last about a millisecond. And sometimes, the signals repeat.
Until recently, that’s about all scientists could tell you about fast radio bursts, or FRBs. Our radio telescopes, which pick up noise rather than light, first detected them in 2007; since then, we’ve recorded a few dozen more, but not enough to be able to put together a compelling theory of what causes them.
With the origin of these signals still unknown, some scientists — notably the chair of the Harvard astronomy department, Avi Loeb — speculate aliens could be sending them.
Now, researchers based in Canada, where a radio telescope exceptionally well equipped to detect FRBs began operating in 2018, have added a new piece to the puzzle. A few previously detected FRBs had been shown to repeat sporadically, without any regular pattern. But by observing the sky from September 2018 through October 2019, the researchers in Canada found 28 bursts — including one that repeats with a very regular pattern indeed: It appears every 16.35 days, to be exact.
This is the first time scientists have detected such a pattern in an FRB source. The peculiar signal is coming from a massive spiral galaxy 500 million light-years away. The source sends out one or two bursts of radio waves every hour, over four days. Then it goes quiet for 12 days. Then the whole process repeats.
So why is a radio signal repeating every 16 days like clockwork, and what can that teach us about its origins?
That’s the central question of new paper authored by the Canadian Hydrogen Intensity Mapping Experiment in collaboration with the Fast Radio Burst Project (CHIME/FRB).
There are a couple of things we know for sure. The 16-day “periodicity” cannot be occurring “by chance coincidence,” the scientists write, and it’s “an important clue to the nature of the object.” It’s clear that the FRB can’t be originating from a cataclysmic event, like a star going supernova, since that’s a one-time affair.
But beyond that, the scientists really aren’t sure. They propose a few possibilities.
One explanation is orbital motion. Celestial bodies are known to orbit on regular timescales, so a pair of objects — like a star and a black hole — could account for the 16-day pattern. “Given the source’s location in the outskirts of a massive spiral galaxy,” the paper says, “a supermassive black hole companion seems unlikely, although lower-mass black holes are viable.”
The authors say FRBs could be generated if giant radio pulses from an energetic neutron star are eclipsed by a companion object. They also note that periodicity could arise from the rotation of a star, but that’s a tricky hypothesis: Previously observed sources have had way shorter periodicities (a few hours, not a couple of weeks) and way less strength (we’re talking nine orders of magnitude less) than FRBs have.
In short, the authors don’t know what’s causing FRBs. But aliens are not on their list of possibilities. They end their paper calling for more research.

Are aliens causing fast radio bursts? Probably not.

While grounded speculation among astrophysicists suggests that FRBs are caused by neutron stars, stars merging, or black holes, it’s a different theory that has caught hold of the public imagination: Maybe they’re caused by intelligent alien life.
study by Avi Loeb and Manasvi Lingam of Harvard University, published in 2017, argued that the patterns could plausibly result from extraterrestrials’ transmitters. The paper is theoretical; it doesn’t propose any evidence for the “aliens” hypothesis, it just argues that it’d be compatible with the recorded data so far. They concluded it’d be physically possible to build such a transmitter — if you had a solar-powered, water-cooled device twice the size of Earth.
The hypothesis raises some obvious questions. FRBs come from all over space, not just from one particular region. Are we to assume that these aliens are sophisticated enough to have spread across many galaxies, but that there are no signs of them other than these energy bursts? Or that many civilizations independently settled on the same odd style of energy burst?
The 2017 paper argues for the latter possibility: that many civilizations have separately built such massive transmitters and are sending out FRBs. “The latest estimates suggest that there are ∼ 10^4 [10,000] FRBs per day,” the paper observes, which would suggest an implausible number of extremely busy, scattered alien civilizations. To resolve that, the paper argues that perhaps “not all FRBs have an artificial origin — only a fraction of them could correspond to alien activity.”
But once we concede that FRBs can occur naturally, and conclude that at least some of them are occurring naturally, why conclude that any of them are artificial?
And if a civilization had the astounding technical capacities to build solar-powered, planet-size transmitters, wouldn’t it be doing other things we could detect that would be less ambiguous?
“The possibility that FRBs are produced by extragalactic civilizations is more speculative than an astrophysical origin,” the paper concedes.
Indeed, that’s what the CHIME/FRB researchers behind the new paper think. “We conclude that the periodicity [of the FRB] is significant and astrophysical in origin.”

The broader debate over alien life

Scientists disagree about how to interpret phenomena like FRBs in large part because they disagree about how plausible alien life is in the first place. In statistical terms, they have different priors, meaning that the background assumptions they are using to interpret the new evidence are different.

From one perspective, the universe is astonishingly large, full of habitable planets like Earth where life could evolve as it did here. Sometimes, that life would become intelligent. We’d expect such a universe to have lots of flourishing civilizations — as well as lots of extinct ones.
This is clearly the expectation that motivates Harvard’s Loeb. “As soon as we leave the solar system, I believe we will see a great deal of traffic out there,” he said in a 2019 interview with Haaretz. “Possibly we’ll get a message that says, ‘Welcome to the interstellar club.’ Or we’ll discover multiple dead civilizations — that is, we’ll find their remains.”
If you think that space is teeming with aliens, it’s not so much of a stretch to interpret astronomical phenomena as remnants of those aliens.
But if you’re looking at the same data with the expectation that we’re alone in the universe, you’re much likelier to conclude that there’s a natural explanation for FRBs.
It’s weird, given that the universe is so vast, that we seem to be alone in it. Physicist Enrico Fermi was the first to spell out this dilemma, and it’s named after him: the Fermi paradox. The paradox is that, under some reasonable assumptions about how often life originates and reaches technological sophistication, we should be able to detect signs of thousands or millions of other civilizations. And yet we haven’t. Recent investigations suggest that the paradox may have a mundane resolution — under more accurate assumptions about how life originates, we are very plausibly, alone.
The disagreement between researchers who think advanced civilizations must be extremely rare and those who think they’re common is a fairly substantive one. For one thing, if advanced civilizations are common, then why can’t we see them? We might be forced to conclude that they’re fairly short-lived. That’s Loeb’s take: “The technological window of opportunity might be very small,” he told Haaretz.
That take would have some consequences for us. If there’s some danger ahead that destroys every technological civilization that runs into it, we might expect that we’re living in a “vulnerable world” where future technological advances will destroy us, too.
In that way, disagreements over aliens have big implications. But that’s probably not the reason everyone cares about them. Offhand speculation about aliens tends to get vastly more coverage than anything else in astronomy. Whether we’re alone in the universe feels like a profoundly important question, for its implications for human civilization but also for its own sake. The lack of evidence suggesting phenomena like FRBs are alien in origin won’t be enough to stop people from wondering.

Something in Deep Space Is Sending Signals to Earth in Steady 16-Day Cycles

Scientists have discovered the first fast radio burst that beats at a steady rhythm, and the mysterious repeating signal is coming from the outskirts of another galaxy.

A mysterious radio source located in a galaxy 500 million light years from Earth is pulsing on a 16-day cycle, like clockwork, according to a new study. This marks the first time that scientists have ever detected periodicity in these signals, which are known as fast radio bursts (FRBs), and is a major step toward unmasking their sources.

FRBs are one of the most tantalizing puzzles that the universe has thrown at scientists in recent years. First spotted in 2007, these powerful radio bursts are produced by energetic sources, though nobody is sure what those might be. FRBs are also mystifying because they can be either one-offs or “repeaters,” meaning some bursts appear only once in a certain part of the sky, while others emit multiple flashes to Earth.

Pulses from these repeat bursts have, so far, seemed somewhat random and discordant in their timing. But that changed last year, when the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB), a group dedicated to observing and studying FRBs, discovered that a repeater called FRB 180916.J0158+65 had a regular cadence.

The CHIME/FRB team kept tabs on the repeating burst between September 2018 and October 2019 using the CHIME radio telescope in British Columbia. During that period, the bursts were clustered into a period of four days, and then seemed to switch off for the next 12 days, for a total cycle of about 16 days. Some cycles did not produce any visible bursts, but those that did were all synced up to the same 16-day intervals.

“We conclude that this is the first detected periodicity of any kind in an FRB source,” the team said in a paper published on the preprint server arXiv in late January. “The discovery of a 16.35-day periodicity in a repeating FRB source is an important clue to the nature of this object.”

Scientists recently tracked down this particular FRB to a galaxy called SDSS J015800.28+654253.0, which is a half a billion light years from Earth. That may seem like a huge distance, but FRB 180916.J0158+65 is actually the closest FRB ever detected.

But while we know where it is, we still don’t know what it is. To that point, the beat of the FRB suggests that it might be modulated by its surroundings. If the source of the FRB is orbiting a compact object, such as a black hole, then it might only flash its signals toward Earth at a certain point in its orbital period. That scenario could potentially match this recognizable 16-day cycle.



It’s also possible that we are witnessing a binary system containing a massive star and a super-dense stellar core known as a neutron star, according to a study published on arXiv on Wednesday by a separate team that looked at the same data. In that model, the neutron star would emit radio bursts, but those signals would be periodically eclipsed by opaque outflowing winds from its giant companion.

Another scenario is that the FRB rhythm isn’t tempered by another object, and is sending out the pulses directly from the source. Scientists have previously suggested that flares from highly magnetized neutron stars, called magnetars, might be the source of some FRBs. But since magnetars tend to rotate every few seconds, a 16-day cycle does not match the expected profile of a magnetar-based FRB.

Ultimately, the CHIME/FRB team hopes to find similar patterns in the handful of known repeating bursts to see if these cycles are common. The researchers also plan to keep a careful eye on FRB 180916.J0158+6 while it is active in order to spot any other details that might point to its identity.

FRBs have baffled scientists for more than a decade, but new facilities such as CHIME are revealing new details about these weird events every year. While we still don’t know what is blasting out these bizarre signals, the discovery of a clear tempo from one of these sources provides a significant lead for scientists to follow.

Trump vowed to not cut Social Security and Medicare — hours before proposing just that

The president is either brazenly lying about his 2021 budget or doesn’t know what’s in it.

President Donald Trump posted a tweet on Saturday vowing, “We will not be touching your Social Security and Medicare in Fiscal 2021 Budget.” One day later, the Wall Street Journal published a report indicating that Trump is doing exactly that with his budget proposal.

The Journal’s report, which came a day ahead of the administration officially releasing its budget on Monday, indicates that Trump’s $4.8 trillion budget includes “steep reductions in social-safety-net programs,” including cuts to Medicare, Medicaid, and Social Security disability programs:

The White House proposes to cut spending by $4.4 trillion over a decade. Of that, it targets $2 trillion in savings from mandatory spending programs, including $130 billion from changes to Medicare prescription-drug pricing, $292 billion from safety-net cuts—such as work requirements for Medicaid and food stamps—and $70 billion from tightening eligibility access to disability benefits.

That Trump is proposing cuts to these programs isn’t surprising — his 2020 budget cut all three as well. It’s a long-running contradiction for the president. He often says he won’t touch these entitlement programs, but he’s continued to employ Republican Party officials who make cutting these programs center to their work.
Trump keeps proposing entitlement cuts and then denying that he did so

In 2015 and ’16, Trump differentiated himself from the rest of the Republican presidential hopefuls by campaigning on a vow to not cut entitlements.

“I’m not going to cut Social Security like every other Republican and I’m not going to cut Medicare or Medicaid,” Trump told the Daily Signal, a conservative publication affiliated with the Heritage Foundation, in 2015.

As his budget proposals indicate, this promise was an empty one. Trump, however, seems to realize that cutting entitlements is a political loser for him, and as a result has continued to make assertions about preserving them that are at odds with reality.

All Republicans support people with pre-existing conditions, and if they don’t, they will after I speak to them. I am in total support. Also, Democrats will destroy your Medicare, and I will keep it healthy and well!— Donald J. Trump (@realDonaldTrump) October 18, 2018

Last month, however, Trump seemed to have a moment of radical honesty when he told CNBC during an interview conducted in Davos that “at some point” entitlement cuts will be on the table.

CNBC: Will entitlements ever be on your plate [for cutting]?

TRUMP: "At some point they will be"

CNBC: But you said you wouldn't do that in the past

TRUMP: "We also have assets that we never had" pic.twitter.com/FgZnzYz33l— Aaron Rupar (@atrupar) January 22, 2020

Those comments created a negative stir, so the very next day Trump tried to walk them back.

Democrats are going to destroy your Social Security. I have totally left it alone, as promised, and will save it!— Donald J. Trump (@realDonaldTrump) January 23, 2020

Fast-forward less than a month, and Trump is again pushing entitlement cuts. It’s whiplash-inducing.
Democrats have already signaled Trump’s budget is going nowhere

While Trump tries to have it both ways by proposing entitlement cuts while claiming he’s not really doing that, Treasury Department spokesperson Monica Crowley was somewhat more straightforward during a Monday morning appearance on Fox Business.

Asked by host Stuart Varney if she agrees that the new budget “hits the safety net,” Crowley said the president “understands that Washington’s habit of out of control spending without consequence has to be stopped.”

But for Trump, not all spending is bad. While his budget cuts non-defense spending by 5 percent, he actually slates defense spending for an increase to $740.5 billion for fiscal year 2021.

Budget proposals are just that — proposals. And while Trump insists that Republicans are the ones trying to save entitlements from destruction, the irony is that the truth is exactly the opposite: Entitlement cuts are dead on arrival as long as Democrats control a chamber of Congress.

House Budget Committee Chair John Yarmuth (D-KY) alluded to this reality in a statement he released on Sunday blasting Trump for “proposing deep cuts to critical programs that help American families.”

The “budget reportedly includes destructive changes to Medicaid, SNAP, Social Security, and other assistance programs that help Americans make ends meet — all while extending his tax cuts for millionaires and wealthy corporations,” Yarmuth wrote. “Congress will stand firm against this President’s broken promises and his disregard for the human cost of his destructive policies.”
Trump: The economy is the best in history. Also Trump: We need to cut raises for federal workers.

The president is shamelessly trying to have it both ways.

President Donald Trump wants you to believe the American economy “is the best it has ever been” — but he also wants you to believe that “serious economy conditions affecting the general welfare” justify his proposal to cut a scheduled pay raise for federal workers.

The juxtaposition illustrates how nothing Trumpworld says can be taken at face value, as well as the disdain the administration has for non-military government workers.


Trump made the aforementioned claim about the economy being “the best it has ever been” during his State of the Union speech on February 4. He reiterated it on Tuesday.


BEST USA ECONOMY IN HISTORY!— Donald J. Trump (@realDonaldTrump) February 11, 2020

During congressional testimony on Wednesday, Treasury Secretary Steven Mnuchin echoed Trump’s theme, telling senators that the president’s “economic freedom agenda is working” and that “American families are earning more each year ... growth [will] reduce our debt and deficits over time.”

But at the same time as Trump and administration officials are painting this rosy picture, the president quietly sent a letter to Congress on Monday announcing that as part of his 2021 budget proposal, he wants a scheduled pay raise for civilian federal workers cut from 2.5 percent to just 1 percent. The letter cites a “national emergency or serious economic conditions affecting the general welfare” and claims federal agencies “cannot sustain such increases.”

From the letter, which was first reported on by Slate:

Title 5, United States Code, authorizes me to implement alternative plans for pay adjustments for civilian Federal employees covered by the General Schedule and certain other pay systems if, because of “national emergency or serious economic conditions affecting the general welfare,” I view the increases that would otherwise take effect as inappropriate.

Under current law, locality pay increases averaging 20.67 percent, costing $21 billion in the first year alone, would go into effect in January 2021, in addition to a 2.5 percent across-the-board increase for the base General Schedule.

We must maintain efforts to put our Nation on a fiscally sustainable course; Federal agency budgets cannot sustain such increases. Accordingly, I have determined that it is appropriate to exercise my authority to set alternative pay adjustments for 2021 pursuant to 5 U.S.C. 5303(b) and 5 U.S.C. 5304a.

One thing that has negatively affected the “sustainability” of the federal budget is the 2017 Tax Cuts and Jobs Act. Though that package resulted in tax cuts for most Americans, it mostly benefited rich people and corporations, creating a massive spending gap while only modestly stimulating the economy. Trump’s 2021 budget proposal cut entitlement programs while making those tax cuts permanent.

And while the American economy is strong, it is not the best in history. As the Washington Post notes, Trump “has never achieved an annual growth rate above 3 percent, but in 1997, 1998 and 1999, the gross domestic product grew 4.5 percent, 4.5 percent and 4.7 percent, respectively.” The unemployment rate, while low, is not the lowest in history, and Trump’s job creation record lags Obama’s. Still, the notion that the government can afford $738 billion to spend on defense but not a modest raise for federal workers is hard to buy.

The stock market is hitting all-time highs, and corporate profits have hit unprecedented levels. But this is cold comfort to federal workers who, according to one recent study, make 27 percent less than their private sector counterparts.

Alluding to the disconnect between the haves and have-nots in Trump’s economy, Tony Reardon, president of the National Treasury Employees Union, said in a statement that “For an administration that has added $3 trillion to the federal debt, gouging federal employee pay and benefits in the name of deficit reduction is ridiculous.”
SOME GOOD NEWS
The Senate just voted to check Trump’s ability to take military action against Iran

Eight Republicans joined with Democrats to send the president a message.

The Senate, on Thursday, once again attempted to limit the president’s war powers
.

In a 55-45 vote, lawmakers passed a resolution that would require President Donald Trump to obtain congressional approval if he wanted to take additional military action against Iran. It’s the latest lawmaker response to an airstrike Trump authorized in early January that killed Iranian Gen. Qassem Soleimani, and follows the passage of a similar measure in the House. Differences in the legislation mean is must be voted on by the lower chamber before it heads to the president’s desk.

The war powers vote notably garnered bipartisan support from a majority of senators, including eight Republicans. Sens. Susan Collins, Jerry Moran, Rand Paul, Mike Lee, Todd Young, Lisa Murkowski, Lamar Alexander, and Bill Cassidy voted with Democrats to advance the measure, which did not come close to reaching the 67-member supermajority needed to override a presidential veto.


Even if this resolution is passed by both chambers of Congress, it’s expected to be rejected by the president, who was calling via Twitter for Republicans to vote it down earlier this week. “If my hands were tied, Iran would have a field day,” Trump wrote.

The Thursday Senate vote marks the latest attempt to check the president’s war powers, which have evolved significantly, in part with the help of past congressional authorizations. Last year, both the House and Senate also voted to curb the president’s ability to continue the United States’ support for the war in Yemen, though those measures were similarly vetoed. Democratic lawmakers have also pushed to include amendments in the annual must-pass defense budget bill that would have reined in the president’s ability to unilaterally take military action in Iran, but those were stripped out of the final versions.

Although it’s ultimately just a message, the passage of this Senate resolution enables Democrats to make a point and put Republicans on the record. It also further establishes where Congress stands on the matter — and signals to Trump just how seriously lawmakers on both sides of the aisle are taking it.
War powers resolutions keep coming up

In the past year, Congress has tried repeatedly to check Trump’s ability to take military action, efforts that have included support from some Republicans. Although Congress hasn’t waded into specific questions tied to the conflicts in Afghanistan and Iraq, there has been a growing push to prevent the president from using past authorizations of military force to conduct attacks elsewhere in the world.

As Vox’s Ian Millhiser explained, the expansion of these powers has partly been enabled by the courts over the years, as well as legal opinions offered by the executive branch:

One consequence of judicial deference is that there is fairly little case law explaining when the executive branch can and cannot take military action. Instead, most of the legal opinions in this space were drafted by executive branch officials. According to Jack Goldsmith, a professor at Harvard Law School who led the Justice Department’s Office of Legal Counsel during the second Bush administration, “Practically all of the law in this area has been developed by executive branch lawyers justifying unilateral presidential uses of force.”

These lawyers, Goldsmith warned, “view unilateral presidential power very broadly.”

The focus of the Iran resolution, an effort led by Sen. Tim Kaine, is pretty straightforward: It reiterates that Congress has not declared war against Iran, and that current congressional war authorizations don’t apply. It also would require the president to remove US troops from any “hostilities” with Iran within 30 days if he didn’t gain congressional approval. It includes exceptions for cases of self-defense and responses to imminent attacks.

“We’re now at a boiling point, and Congress must step in before Trump puts even more of our troops in harm’s way,” Kaine said in a statement.

Lawmakers have repeatedly tried to draw boundaries limiting the use of past Authorizations for Use of Military Force (AUMF) that were approved after 9/11 and before the Iraq War. These authorizations, both of which are nearly 20 years old, have since been used to justify other military action across the Middle East.

Last month, the House passed its own version of this war powers resolution, sponsored by Rep. Elissa Slotkin, as well as two resolutions from Reps. Ro Khanna and Barbara Lee, which would withdraw US military support for the war in Yemen and repeal the 2002 AUMF that enabled the president to take military action in Iraq.

As legal experts have told Vox, however, Congress can only do so much depending on how the administration interprets the various restraints that are passed. If Kaine’s measure were approved and signed into law, for example, it’s possible the administration could attempt to bypass it.

The vote on this resolution follows a January briefing from the Trump administration about the airstrike against Soleimani that’s since prompted intense criticism from both Democrats and Republicans. After Thursday’s vote, Congress’s ability to check Trump remains limited, in part because some Senate Republicans aren’t interested in strengthening it.
