This is an interesting math problem. 0+0=0. Because you can add two zeros together, the zeros must exist as separate entities. But, if the zeros are separate entities, then why would they only equal one zero? It seems to me that zero in mathematics exists, but has no size. How can something exist and yet have no size? That's clealy what the equation 0+0=0 is suggesting. Otherwise, 0+0 could not equal 0, but would have to equal only 0+0. Nonetheless, you could argue that zero by its very existence must have some size, but it is so tiny, it is irrelevant for purposes of mathematics, and hence zero plus zero is almost (but not quite) exactly the same as zero.

The same with nothingness. If nothingness exists, it must have some size. Isn't that what existence is all about? However, perhaps the size of nothingness is so incredibly small, that it takes a whole hell of a lot of multiple nothingnesses to create something the size as matter. Isn't this similar to the Big Bang? An extremely small point explodes into the universe? Question: How big was the point that started the Big Bang? It seems to me that it must have had some size (however small), otherwise it could never have existed.
