Episode 180: Wormholes through Space and Time, with John Cramer

Feature Guest: John G. Cramer

They are the stuff of science fiction, but wormholes are also the subject of intense scientific debate. Can wormholes provide a mechanism for faster than light travel through space and, even more intriguing, do they open the door to travel through time? Today we’re joined here at The Star Spot by one of the world’s foremost authorities on wormholes, Professor John G. Cramer, to share results from his thought experiments on wormholes and his laboratory experiments aimed at changing the past.
