Title: Time travel has been simulated by Australian physicists
Post by: Freddy on June 25, 2014, 14:57:43 PM
QuotePhysicists at the University of Queensland in Australia have used photons - single particles of light - to simulate quantum particles travelling through time and study their behaviour.

They were hoping to find out more about whether time travel would be possible at the quantum level - a theory first predicted in 1991.

For the likes of macro objects and information, the answer still seems ... no we can't time travel.

All the maths that point to it require a substance that emits negative energy. This substance has not been found and may not exist. Though we still haven't found dark energy and dark matter so never say never.
