The particles don't always destroy eachother. Near black holes, sometimes one particle goes into the gravity well and another doesn't.
They can even do it in a lab too. All I was saying is that creation annihilation is the sour e of dark energy in empty space.
It's energy neutral. Anything else would defy conservation of mass/energy
What's energy neutral?
It takes as much energy to make a quark and an antiquark as they give off when they meet.
Oh ok. That is not quite what I think of when I think Energy Neutral. I see that as the price of admission past the Energy Conservation police. Thanks.
