Solution to the time travel problem

Even if there is no way to do it in the real world, at least it should in principle be more possible than actual time travel.

If we assume the multiverse is a literally limitless number of universes, there should also be countless universes that are an exact copy of our own. Just like it is today, how it was hundred years ago, or ten million years ago. The whole history of earth could be found in a present day parallel universe.
The only problem is to find those who are an exact copy of a specific point in time of our past in every possible detail and how to get there.

If you could do that, it would open up for interesting adventures without having to worry about paradoxes.
