What if many universes with distinct physical laws exist and selective pressure is exerted on a universe for a certain property?

For example, if gravity were too strong or too weak, the universe as we know it would not exist; it would fall apart very shortly after its birth. If an equal amount of matter and antimatter existed, the universe may have completely annihilated itself. This didn’t happen, but in an infinitude of universes, it certainly has in the majority of them.

Or, even more tantalizingly, what if this universe was selected for its ability to support intelligent life? Maybe there’s something to the strong anthropic principle? Could the universe we live in be subject to the same laws that dominate life within it?
