Imagine yourself on a train that moves by the speed of light and you stayed in it for 50 years, according to the theory of relativity, all what will happen that 2 weeks will be passed for people who are inside this train! in other words you traveled to the future, Enistien based his theory on a fact that says time is just a dimension, like length, width & depth
and due to that, time can be expanded and shrink !
I don't want to talk in details about that, all you need to know to understand this very true concept
that time is very relative...
