But that assumes that you believe in destiny.

If you go back in time and step on something, the future would change but in a mostly unnoticable way. Unless you stepped on something important.

For example if you stepped on an apple tree sapling in England and stopped it's growth, and that apple tree just happened to be the one Newton was sitting under when he thought up the theory of gravity (this is just an example, I know its just a legend), depending on what you believe in (multiverse or whatever), either you would just create another parallel world where either Newton didn't develop the theory that day or at all, but the world you came from would remain unchanged. Or if you believe in the other theory your world would change that either the gravity theory was developed another day or was developed by someone else another day.

Either way there's no way to prove anything regarding time travel so essentially all of these theories are just providing material for science fiction novels.

Unless of course someone actually does develop a time machine, but then we'd just have to take that person's or group's word for what happened during the testing of the theories since there would be no way to fully prove that anything at all happened, since they would be the only ones that would even notice a difference, unless their memories adapt to the changed world.

Is there really any point in throwing these theories around at all?
