In Brief
University of Queensland scientists learned that a simulation of two wormhole-travelling photons might interrelate, signifying hopping through time is conceivable at smallest scales.
  • According to scientists photons can travel through time. They already have simulated directing quantum light particles to the past for the first time in the history.
  • PhD student Martin Ringbauer explains that in their study: “For the first, ‘photon one’ would travel through a wormhole into the past and interact with its older version. In the second, ‘photon two’ travels through normal space-time but interacts with a photon that is stuck in a time-travelling loop through a wormhole, known as a closed timelike curve (CTC).”
  • Tim Ralph, UQ Physics Professor, said: “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 travelling photon.” Their study might help to comprehend how time-travel could be conceivable in the quantum realm.
