So, if one of the consequences of the Chaos Theory is that minor starting differences result in very different outcomes ( I am not so sure if that is true in a global scale because but let's assume for a thought experiment), there should be many universes where life has not emerged yet. Now, hold that thought.
Also, as a consequence of the Chaos Theory, it is only possible to predict something exactly if we take into account all the tiniest starting conditions. Technically, if is impossible to predict something before it actually happens. But maybe easier some time after an event happened ( not technically predicting but explaining).
Now, if we can put all the starting conditions away, stop the time here, calculate away, send the result back, we have a prediction and we can restart the time. Obviously, starting the time is a bit cumbersome because we can only calculate at the cost of time, so we need to get time somewhere.
Let's go back to the initial thought: there should be empty universes whose time is not used for anything, so we can just take it to do our calculations. Forget about side effects for now, since that is what we always do.
The only problem is how to get to that universe. We'll imagine for now. Imagine there are particles called Imaginons (for obvious reasons). They are very small and we cannot detect them. For not just because they are so small but also because the universe is full of are tiny black holes, whose event horizon is just the size of Imaginons. By consequence, nothing from our observable world is affected but imaginons always fall into those holes - and - mostly for our own convenience - they go to another universe, the universe we can use as our computer. To realize that computation, all that we need to do (theoretically) is to get a lot of Hawkins radiation blowers to move the tiny black holes to wherever we are going to use them. Encode our world's data and computation algorithm into Imaginons just before those enter the black holes, and then extract the results by manipulating the side of the black holes connected to the other universe ( on this side we can see the result from the change of the radiation from the black holes).
I guess there can be some problems with the other universes since not all of them are suitable (maybe populated, slower in time that ours etc.) and the fact that experimentally imaginons and tiny black holes do not exist, by otherwise, it should work.
To conclude, I am not sure why we would need to predict anything so badly to resort to such measures. Maybe if there's so little biological life left that it is cheaper to calculate things than to make a few billion of babies to run the same experiment in real time.
