Einstein's space-time is only a 2D universe, not 4D.
However, I think that traveling into the future is highly problematic at best, nearly impossible at worst.
TARDIS? Seriously? I hope he came up with this "research" on his own time and not UBC's.
When you think of a time machine don't just imagine a person travelling back in time. I'd be really happy if a single photon could.

Apr 27, 2017We can't confirm 100% a theory, at best the theory has passed other test. This is important cause that means we actually don't know if we can travel in time. We can only know that when we travel in time, beside a lot of paradox in time travel make us see something is amiss in the nature of time.
