Is Time Travel Through Wormholes Actually Possible?

Neil deGrasse Tyson and Kip Thorne discuss the theoretical physics behind wormholes and time travel, exploring whether such a concept could allow someone to meet their younger self. Their conversation traces the origins of these ideas—from a pivotal phone call with Carl Sagan that sparked Thorne's work on wormhole time machines, to the quantum mechanical barriers like vacuum fluctuations that could ultimately prevent them from functioning. Along the way, they reflect on Stephen Hawking’s take on the subject and the possibility that quantum gravity might destroy any time machine the moment it’s created—an idea that helps keep the universe, as Hawking once quipped, “safe for historians.”
