Carlo Rovelli on White Holes
Theoretical physicist Carlo Rovelli discusses his book, White Holes, which traces the ongoing adventure of his own cutting-edge research and outlines some of the most astounding ideas in astrophysics and cosmology. Rovelli investigates whether all black holes could eventually turn into white holes, equally compact objects in which the arrow of time is reversed.
Carlo Rovelli is a physicist and writer. He is currently a Distinguished Visiting Research Chair at the Perimeter Institute and core member of the Rotman Institute of Philosophy of Western University.
