Déjà vu

A number of years ago I played around with a couple of assumptions to see how these would affect things, the two assumptions were

1. Nothing is random

2. Nothing is infinite

Playing around with these assumptions I think can result in some interesting situations.

First consider dropping a glass of milk onto the floor. The glass would break and the milk would spill on the floor in a certain way. If we then repeat the process again with a new glass of milk keeping everything down to the tiniest components the same, the glass and the milk would break and spill in exactly the same way and the exact same pattern as before.

Now consider a perfectly bouncy ball bouncing around in a box, since there are only a finite number of arrangements (albeit a very large number considering all the factors involved), for example, where the ball could be inside the box, it’s speed and direction, the arrangement of the air molecules inside the box, the ball will eventually arrive at an exact same arrangement that it has taken before. Since nothing is random, once this happens the sequence would simply repeat itself again and again in a loop. This is because like the glass of milk breaking, the same exact arrangement would result in exactly the same result, and because the result is that everything ends up in exactly the same arrangements.

Taking this on a universal scale, it would imply that either the universe has a beginning and an end (for example if the ball was not perfectly bouncy it will eventually comes to a stop) or if the universe keeps progressing it will eventually repeat itself due to the limited permutations (though a very large number) it can take. Some could argue that this would break the assumption because the universe would repeat itself infinitely but I see it as more of a finite loop.

Taking things slightly further these assumptions would also permit moving time around to a certain degree because if you want to move to say 1945, you would only need to find a way to arrange the universe exactly as it was then (although this of course is very unlikely to be easy). Time travel however, would not be possible with this method since you would first need to arrange the universe as it was in 1945, but then you would need to create extra mass and energy to create your present self (the time traveler) as well, or else you would need to take mass and energy from elsewhere in the universe but that would result in the universe not being exactly the same as it was in 1945.

So since the universe would be repeating itself in a finite loop with these two assumptions we could all be living a Déjà vu moment right now, infact we could have been in this very moment several times previously.
