TMO Background Mode Interview with Cosmologist Dr. Andrew Friedman

Dr. Andrew Friedman is an astronomer, cosmologist, and data scientist. He’s currently an NSF funded Assistant Research Scientist at the University of California at San Diego Center for Astrophysics & Space Sciences. He is also a Research Affiliate in the MIT Program in Science, Technology and Society. He holds a Ph.D. in Astronomy and Astrophysics from Harvard.

We chatted about how science fiction inspired him as a youth to become a cosmologist. Also, how important it is to have a Ph.D. thesis advisor who’s enthusiastically supportive. Then, we got into some cool topics of cosmology: using Type Ia supernovae to measure the rate of expansion of the universe, why infrared observations of those stars are helpful, whether quantum entanglement suggests a substrate on which spacetime resides, the multiverse, and the implications of the Planck length and Higgs field for our very existence.
