Is it possible that a computer could become so powerful that it could not only predict the future with 100% accuracy, but also be able to look back into the past?

Imagine that we somehow develop artificial intelligence strong enough to predict the future with 100%, or near 100% accuracy. This is quite a common idea. 

But what I’m more interested in is the question is whether a computer could accurately look into the past as well. If a computer hypothetically could become powerful enough to have access to all the information in the universe - and be able to pinpoint the exact coordinates of a particle on the other side of the galaxy - could it also be powerful enough to know where the particle has been in the past? Could a computer then, be able to sort of “time-travel” to the past (without actually physically going back in time) without altering it since it would know exactly where all particles were at any given time?

On our current understanding of quantum mechanics, no.

It isn't a feature of computional capacity. Rather the problem is that you can know either the location or trajectory of a given particle. But you cannot know with certainty both simultaneously. 

This is because observation (itself) seems to interferes with the thing observed. 

So if you know the location of the particle you have uncertainty about the path and if you know path then you have uncertainty about the location along that path.

Again this isn't a feature of computional capacity so far as we understand.

Edit: It has been correctly pointed out that the problem with the observation of quantum particles and the problem of uncertainty are distinct problems. Which would mean even by solving one we wouldn't necessarily solve the other.
