Nothing is everything.

[Captain Scarlet]

To state that nothing exists, is a horribly incoherent. By definition nothing must be the absence of anything; since we have never observed that in the whole of reality we can at least state to a very high degree of probability that nothing is not a possible state. In much the same way, when the something cannot arise from nothing argument is tripped out, that falsely assumes that the universe at T0 was in a state of nothingness. But this seems a highly improbable state of affairs. It is perhaps more interesting that there is only a small surplus of matter over antimatter in our universe and when all energy and matter is totaled on both sides of the positive and negative divide, there is a lot less in our universe than we suppose or observe. So in some sense a small something can give rise to bigger set of +ve somethings and -ve somethings.
