That force might not be necessary. There are at least two ways this would work:
* Events after the time travel event in the past bring about the future from when the time traveler comes. It seems forced, I admit, to assume that it just works out. I can see it working if the time traveler does not exactly know what they did in the past, which could make the paradoxes more beningn.
* If you travel in time, the timeline gets forked at the moment where you intrude. This is what happens in Dragonball Z.
