Given that it's canon that particles appear and disappear from the
"quantum foam", all the time, (with a nod to Heisenberg so that they Don't
Really Count), and that gravity is always positive.
What happens to the mass of all those particles?
IOW, pick a point, any point, draw a line in any direction to the edge of
the universe. Along that line there are particles appearing and
disappearing all the time.
So why don't we notice the mass of all those particles?
Is it that they cancel out?
Or that they are only around for so short a time that they don't count?
Or am I missing the point?
If the particles have rest mass, then the energy that is required for their formation also has mass, and is therefore exerting gravity.
Or that these particles only appear in areas where there is a strong field of some sort; since most space is empty, particles aren't appearing there.
