      This is definitely more Mark’s area of expertise, but I think in theory, yes! However, wormholes are still only hypothetical to the best of my knowledge, and I don’t think we’re very close to actually being able to form/use them.

      Absolutely yes – if the exist. Wormholes are a very weird mathematical object that popped out of Einstein’s equations for general relativity when solved assuming certain things about our Universe.

      However, they require this thing called negative energy – and no one knows what that is, or if it exists.

      Here’s a cool video about time travel. The last 40 seconds are about wormholes 🙂

      in the movie “Event Horizon” the characters came across a spaceship which had travelled through a wormhole, with terrible consequences for the passengers!
