If time travel becomes possible, do you think that anyone should be allowed to travel to the past?

Backward will never be possible, so no problem. And once you go forward, you aren't coming back. Tomorrow you will have traveled to the future from today.

HELL no. Ever heard of the butterfly effect?

I really wish that this could happens but it cant that I could travel to my past :(.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
