For our last episode of our new series on mathematics, we are diving into the subject with the great mathematician Sir Roger Penrose. We ask Roger for his answers to our three favorite fundamental questions: What exists? What is mathematics and how does it work? What's fundamental in the cosmos?

Roger Penrose was a major key in creating the now-standard model of black holes. In the fourth installment of our six-part interview, we discuss how Penrose first became involved in black holes, as well as his key insights that developed from Einstein, Schwarzschild, and Oppenheimer's findings. Throughout his career, Penrose has challenged conventional wisdom in physics, mathematics, and the philosophy of science. He has tackled some of the most profound questions of the universe: How do quantum

Sir Roger Penrose OM FRS is an English mathematical physicist, mathematician and philosopher of science. He is Emeritus Rouse Ball Professor of Mathematics in the University of Oxford and Emeritus Fellow of Wadham College, Oxford. Penrose has made contributions to the mathematical physics of general relativity and cosmology. He has received several prizes and awards, including the 1988 Wolf Prize for physics, which he shared with Stephen Hawking for the Penrose–Hawking singularity theorems. Watc
