Philip Gibbs – Black Holes and Black Holes

A white hole is a purely hypothetical time-reversed black hole. What does general relativity say about them? Would they repel you? Could you fall into a white hole—or only fall out? Could the universe be a white hole?

Philip Gibbs answers all these questions and more in my first interview for Edinburgh Explorations—a series put out by the School of Mathematics and the School of Physics and Astronomy at the University of Edinburgh.

The cover picture, showing the maximally extended Schwarzschild solution containing both a black hole and white hole, was made by Isaak Neutelings.
