Can we travel in time ? The answer should be yes. But the problem is we can’t travel in past we can only travel in future , but it is not so easy because if you travel in future your present have to be sacrificed you will not be able to come back and in future your existence will be vanished.
If we can consider time as an medium which is present all over the universe and moving continuously from within every matter present in universe , then our age will depend on the speed with which it travel from our body, if it travel slow than our age will increase slowly , if it travel faster than our age will be increase quickly. In the same way if we slow down the speed of time when moving in us than we will in future with respect to other matters.
But we can’t do the same to move in past because our present is related with many small things.
Like if We touch any thing in the past that’s connected with our ancestors and us than the time will form a Loop and will threaten out existence.
There is a very famous paradox to explain this….
Hope you all had understood, why it is so difficult to travel in time. Thank you!!!!!
