depends on what stuff you smoke

Time travel is not possible and wormhole travel only allows travel faster than the speed of light over vast distances of space.

Maybe. But what is not possible is changing anything via time travel. In our universe, stuff happens but it never un-happens. If you go back and kill your grandfather before your father was born, you do not wink out of existence. You already happened. You cannot unhappen. All you have done is to create a new and different time line where your future birth will not happen. Every thing you do while wondering around in the 'past' makes new and different stuff happen than otherwise would not have. But it does not change the past you experienced. it just creates a different past that you experience as a new reality. And what of the time line in the future that you left to travel to the past. Well nothing you do in the past affects that. They have already experienced a past that did not include your time travel shenanigans and that does not change (remember things happen, but things never un-happen). But they are all wondering what happened to you.

In essence, if time travel were possible, then every possible outcome of every variable and willful action may exist.

No. "For such a thing is contrary to reason".

If you could, you could create an infinite loop - you go through the wormhole, wait until it reappears, go through again, and so on ad infinitum, and the universe gains mass. That violates how the universe works.

time travel to past is theoretically impossible coz that will lead to mind baffling paradoxes like u going to the past and preventing ur parents' marriage thus bringing ur existence then to a question mark.... However theoretically u can go into future but that too is a one way journey. U'd never be able to return back..

One-way travel into the future is arguably possible, given the phenomenon of time dilation based on velocity in the theory of special relativity (exemplified by the twin paradox), as well as gravitational time dilation in the theory of general relativity, it is currently unknown whether the laws of physics would allow backwards time .

I don't know. But if it's possible i will go back in time and predict what will happen on 9/11. Nobody will believe me. Then i will get a good video of the first plane crash.

Yes, this answer is from the past, from 10.8.2011 15:07:20

Yes, in 2 months i'm going back to the 1970s where i will use my knowledge of the future to become a trillionaire.

It's theoretically possible,but it depends on developing the proper technology which doesn't exist yet.

And probably won't for many years. We can barely get to the nearest planet right now.

Time is a creation of man not nature so I would say no.
