Time travel would change the world with the butterfly effect

If someone goes back in time, even if he does nothing there, he changes the whole world with the butterfly effect. Because it affects the people around it first, they affect others and spreads like dominoes to the world.

I mean, there is no traveling back in time. If there were, each visit would change the whole world in the long run.
