In this special interview, I was fortunate to speak with Dr. Ronald Mallet, an emeritus professor at UConn. In addition to a lifetime's work in cosmology and astrophysics, Mallet has been trying to work out how our understanding of Einstein's theories of General Relativity might lead to a practical form of time travel. https://physics.uconn.edu/person/ronald-mallett/This interview was part of the Weekly Space Hangout for May 5th, 2021.
