If you were a time traveler that went back in time and stopped their own grandparents from meeting, would it prevent you from being born? That theory is known as the ‘grandfather paradox’, which is often used to disprove time travel, but a group of physicists now know how time-traveling photons would interact for the first time, suggesting that, at a quantum level at least, jumping through time might be possible. Continue reading for a video and more information.
The Daily Mail reports, “Simulating the behavior of photon two allowed the behavior of photon one also to be studied – and the results revealed that time travel on a quantum level seems to be possible. By definition ‘quantum’ refers to the smallest possible particles that can independently exist – such as photons. This same simulation proves time travel is possible for more larger particles or groups of particles, such as atoms. In 1991 it was first predicted that time travel would be possible in the ‘quantum world’ because quantum particles behave almost outside the realms of physics.
