Can time travel ever be possible?
So, what does physics say about travelling forward in time? How can it be achieved?
Travelling forward in time can be achieved through time dilation. This is a consequence of Einstein's theory of relativity which states that time slows down relative to an observer in motion, or in intense gravitational fields. A traveller experiencing time dilation will age slower than someone standing still or in a weaker gravitational field. In these circumstances, time travel to the future is possible.
