ELI5: Is it theoretically possible to predict the future using a super quantum computer?

I was thinking, if you knew every single thing about how the universe started, (which we don't but it's a hypothetical question) and we had an unimaginably powerful quantum super computer that could simulate the universe EXACTLY as it is, then would it theoretically be possible to speed up the simulator and see what happens to earth after the current time on earth. I don't know if any of this made sense but if it does, any answers are appreciated.

Thanks!

The problem is that in order to simulate the universe, you need to know exactly what it looks like. This includes the computer.

So in order to simulate the future you need to be able to simulate the computer simulating the future, ...
