Sandra Faber:
“The Universe and Our Place in It”
February 28, 2024
(Conversation recorded on December 11th, 2023)
Show Summary
On this episode, astrophysicist Sandra Faber joins Nate for a wideview cosmological conversation on the development of the known-universe and the moral implications for humanity’s role within it. We are the first generation with the ability to truly understand the history of the universe and the extreme bottlenecks that Earth and life as we know it had to endure over the last billions of years. This understanding of where we come from gives us insight into who we are – and could perhaps give purpose to those searching for meaning in the vast universe. From the Big Bang on, how did the necessary conditions come together to create the environment so many of us take for granted today? How do the laws of physics restrict everything that has ever happened in the universe – and everything that ever will? Could a deeper understanding of the cosmos shift our culture towards one that values human’s survival into deep time – and incentivize biophysically and ecologically aligned systems?
About Sandra Faber
Sandra Faber is an American astrophysicist known for her research on the evolution of galaxies. She is the University Professor of Astronomy and Astrophysics at the University of California, Santa Cruz, and works at the Lick Observatory. She has made discoveries linking the brightness of galaxies to the speed of stars within them and was the co-discoverer of the Faber–Jackson relation. Faber was also instrumental in designing the Keck telescopes in Hawaii. At UCSC she focuses her research on the evolution of structure in the universe and the evolution and formation of galaxies. In addition to this, she led the development of the DEIMOS instrument on the Keck telescopes to obtain spectra of cosmologically distant galaxies. On August 1, 2012 she became the Interim Director of the University of California Observatories.
