Go read this LA Times interview with CalTech physicist Sean Carroll on entropy, time and the multiverse.

Mr. Carroll is saying that time is irreversible and therefore directional; our world has some type of order, a thrust forward. He also says that this order is highly unlikely to arise on its own and would almost certainly have to have come from some previous set of affairs or other universe:

So you think the way the universe began is unnatural?

Low-entropy configurations are rare.

If you take a deck of cards and you open it up, it’s true that they’re in order. But if you randomly chose a configuration of a deck of cards it would be very, very unlikely that they would be in perfect order.

That’s exactly low entropy versus high entropy.

The universe is more than what we see?

The reason why you are not surprised when you open a deck of cards and it’s in perfect order is not because it’s just easy and natural to find it in perfect order, it’s because the deck of cards is not a closed system. It came from a bigger system in which there is a card factory somewhere that arranged it. So I think there is a previous universe somewhere that made us and we came out.

We’re part of a bigger structure.

This is exactly what I have been thinking about lately. The reality that we are able to perceive is something. It has meaning and direction. However, our world arises from and exists in something else. We don’t know what it is, maybe we are some alien child’s science fair project. Even if that is the case, the alien child’s world exists in something which exists in something etc. Turtles all the way down.

But what do the turtles exist in? If you started two points at zero on a number line and sent one up the positives and one down the negatives at the same pace, they would both keep going towards infinity, but their sum would always be zero, right? So regardless of the turtles, alien science projects, or any other nonsense we can think up the answer is always zero, always nothing, always void.

Maybe?
