Could Time Travel In Fiction be applied to real life?

[TheQuestionGuy14]

I've watched a lot of time travel movies, most are just pure sci-fi. Bht some movies use parallel universes to explain the time travel in the plot.

Here's where my question comes in: Say if time travel ever was invented, but it created parallel universes when people went back. Would this mean there would be no paradoxes? And would this mean there is no causality violations? So, if time travel did create parallel universes, then it could easily be done! Or, would some things still prevent it from happening?

There is no really plausible mechanism that would create parallel universes.
We might live in a self-consistent universe - every effect of time travel is part of our world already.

Do not confuse Fiction and Fantasy.

One big issue with all of these "many worlds theory" in movies and books is that they do not propoerly conform with the scientific aspects of the theory.

For the sake of argument, let us say I go back in time and kill Hitler as a child. According to these movies, the timeline which I will continue to live in once returning back to normal time will be one where Hitler never existed as a dictator. The problem is that by the actual many world theory, you would probably return to a timeline where your actions had no effect. There is just now a new parallel timeline where Hitler never existed and you can never experience this new timeline. Your actions were futile. Even more futile since there was probably already a timeline where Hitler never became a dictator anyways.

Obviously, this is all useless. Many worlds theory is probably wrong and using it to justify sci fi time travel is something we should not be doing here.

And neither is anything you wrote. Seriously.

General speculation in the Sci-Fi forum is not allowed. The question must be tied to a specific Sci-Fi work.
