So here's an interesting thing that I picked up in "Great Theoretical Ideas" today.

I'm going to boil this down a lot, but essentially, simply because the probability of something happening is 0, does not make that event impossible. When you have an infinite number of outcomes, the odds that you choose any single one of them is 0, since 1 over infinity is so insignificantly small. However, that doesn't stop you from being able to choose it, or deny the existence of that event.

Thus improbability does not imply impossibility.

I like it.
