Theory on Time Travel

I think that if we travel back in time, we can't change anything because it's already happened. So if someone decides to go kill their father in the past before they were born, they can't kill them, because the past simply is written the way it is.

I love how time is more location/movement relativity scale in today's society instead of the actual passage of moments. Also, the mathimatical system we use is also flawed.

I think even you try to kill hitler
you will obviously fail and the thing happened in the past will still happen,
or if you stop your parents from meeting together they'll be meeting each other because they were destined to be together...
past is just like a book, you can't come back and look at it but you cannot change it.
But that's only in my opinion though,..

I don't feel like putting up a long post for this right now so I'll leave this to your own research. Look up Grandfather Paradox and World lines.

To put it simple either there is only one timeline and everything must follow that timeline. Even if time travel is possible. or there are multiple timelines and everything that can happen will. Just in a different world line.

just remember, the future can change the past as well.

There's no such thing as a 'paradox' there's no such thing as 'everything is set' business. Time is fluid and change is possible. Those making the changes would be the one 'affected' by any change NOT the rest of us. Time travel 'will' be possible BUT we do NOT have that technology available to us now or even soon. It 'will' be available in the future and it will be used as a 'study' device to actually see what happened and why and 'learn' from it as opposed to changing it.
