time travel

Looks like time travel is possible… for particles of light.
Using a photon, physicists have managed to simulate quantum particles traveling through time. Studying the photon's behavior could help scientists understand some inexplicable aspects of modern physics.
"The question of time travel features at the interface between two of our most successful yet incompatible physical theories — Einstein's general relativity and quantum mechanics," University of Queensland's Martin Ringbauer says in a news release. "Einstein's theory describes the world at the very large scale of stars and galaxies, while quantum mechanics is an excellent description of the world at the very small scale of atoms and molecules."
