ELI5: If we could take a snapshot of every atom in the universe, could we effectively predict the future?

So, a very theoretical question considering it's near impossible to complete any part of it.

However, if we could somehow capture the orientation/position/type/energy states/nature of subatomic particles/etc. of every atom in the universe, compiled this information into a supercomputer and ran it in some sort of physics emulator, could it track the positions of where the atoms will end up based on their surrounding atoms, current momentum, etc (assuming our universe isn't effected by something outside of it)? Basically, are atoms predictable? 

To my understanding, even though the logic would be difficult beyond belief, I think that this *would* be possible. And if so, a fast enough computer (technology we probably won't ever be able to/need to create) should be able to run the simulation of the newly captured world at an accelerated pace, allowing us to literally see into the future. I can't really wrap my mind around the concept of accelerating time though, and there are most likely properties of physics which we don't even know exist, so I have my doubts. There are a lot of 'ifs' in this problem..

Thoughts?

Quantum Mechanics at least suggest, if not prove, that there may be an element of inherent randomness that cannot be eliminated. If that is the case, then it is certainly at least plausible that there is some degree of unpredictability that also cannot be eliminated in macroscopic events.
