The light particles used in the study are known as photons, and in this University of Queensland study, they stood in for actual quantum particles for the purpose of finding out how they behaved while moving through space and time. The team simulated the behavior of a single photon that travels back in time through a wormhole and meets its older self – an identical photon. We used single photons to do this but the time-travel was simulated by using a second photon to play the part of the past incarnation of the time traveling photon,” said UQ Physics Professor Tim Ralph as quoted by The Speaker.
