A team of scientists from the University of Queensland, Australia, have simulated how time-travelling photons might behave; suggesting that, at the quantum level, the grandfather paradox,which makes time travel impossible, could be resolved.

anonhq reports:
The study used photons – single particles of light – to simulate quantum particles travelling back through time. By studying their behavior, the scientists revealed possible strange aspects of modern physics.
