So, it seems that photons might perhaps be able to whiz backwards through time...
The scientist in me really wants to believe that with a little more understanding we might crack time travel. The idea of time travel is so exciting and it's potential near limitless.
But unfortunately, the realist in me keeps returning to the same point. Why, if time travel of some sort becomes possible ever, is there no evidence of any body or thing having returned up until now?
Simply doesn't make sense.
"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," Mr Ringbauer said.
