If you know this, then you also know that the anti matter and matter particles don't always meet, thus no annihilation. My point still stands.
They sometimes don't meet in a sterile mind experiment like Two Photon physics.
In reality, not so much.
However, Hawking radiation, which is still entirely theoretical, is an example of this. Except it requires a nearby event horizon, within which the
antiparticle annihilates with a different particle than the one it was paired with when it came into being.
EDIT: On the other hand, in regards to space being "empty," it doesn't even require photons for matter-antimater creation. The Heisenberg Principle
is enough for this to occur spontaneously.
When discussing empty space, these sorts of exceptions are not what I had in mind. Space, after all, is different from matter. On the larger scale,
space is empty when it's not being occupied by masses of matter.
My point was that there is a definition of the term "space" that differs from "universe," and that the universe is not expanding into empty space. It
is growing because the space itself is growing.
No need to sidetrack into these quantum technicalities, however true they are, for that argument.
