Time Travel

Which time travel movie got the rules right? According to experiments using a quantum time travel simulator, reality is “self-healing,” so changes made to the past won’t drastically alter the future you came from – at least, in the quantum realm.

Wormholes are a sci-fi staple – but could they be science fact? Surprisingly they fit into current physics models, although no evidence has ever been found. Now, researchers have outlined how we might go about looking for wormholes in our own galaxy.

Researchers at the University of Queensland, Australia claim to have simulated the behavior of a single photon traveling back in time and interacting with an older version of itself, in an effort to investigate how such a particle would behave.
