People say you cant go back in time because if you can then we would see space travelers traveling back in time to visit us. Well... what if.. WHAT IF: we didn't travel back to the past because we didn't want to change the past which would later change the future. So in the future the scientists mke an agreement that they'll never travel into the past because they do not want to disturb anything.

If you paid any attention to Terminator's 1-3...you'd know that it's not possible to change the future. I mean, think about it... If they had stopped the rise of the machines, would there have been a Terminator sent back in time at all? NOPE.
Follow logic: Terminators are sent back in time to change the future. If they are put in our present, it is their past. If they succeeded, then their present (our future) would never have existed in the first place. So it makes sense to say that whatever they try to do, being sent to their past changes nothing.
I figure at this point, if there was some way of making a change, you'd get a time paradox, which I don't know too much about.
