Time?

[Damascus]

My idea of time goes kind of like this. I got a lot of the idea from the "Thinking in Ten Dimensions" series on Youtube, or whatever they're called. I've really been thinking about this a lot lately, and I've just been waiting for the chance to post it all!

------------

The entire universe is made up of a bunch of matter moving through time. However, what we might call the multiverse comprises all possible timelines. Or to put it more directly, a multiverse is comprised of "moments" or still frames of all possible states of matter in the universe. Through the mechanism of entropy, the closest frames are linked together. For example, a moment in which you have just dropped a tennis ball is linked directly to a frame where everything is the same, but the tennis ball is slightly lower.

Timelines are created through cause and effect through the mechanism of entropy. The slightest difference creates split (random chance, such as the spin of a quantum particle), in which one frame is linked to two others.

You could say time is an illusion, but with this theory its more of a by-product. Its as real as time, space, or depth. Time is simply a measurement of the distance between "frames."

Here's where it gets tricky. I believe there is no such thing as "time before the Big Bang." Even that there is no such thing as "before" the Big Bang at all. And here's why. If the multiverse is comprised of all possible states of matter, there is one in which all matter is infinitely dense in a single point. However, because of this description, all possible frames that it can be linked to have universes in which the matter is slightly less dense. All possible moments leading away from the Big Bang have a higher entropy. When time is thus measured, all arrows leading away from the Big Bang go into the future.

This is why there is no such thing as time before the Big Bang. Time is dictated by entropy, and the infinitely dense point of matter is the lowest possible entropy you can get. If you were to get in a time machine and try to travel back beyond the Big Bang you would end up spinned around and travelling into the future again. Either that or you would simply stop.

Imagine the multiverse like a big sphere, in which the "past" is south, and the "future" is north. The arrow of time is really quite clear if you live somewhere like Central America. However, as you go into the past, following the line of entropy as it goes lower and lower, you eventually find yourself at a penultimate point. The South Pole. The point of lowest possible entropy in the universe. In the same way, you can't go any more south from here. This is as south as you get. All directions lead North; into the future.

The Big Bang is as "past" as you can possibly get.
