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.


well, there are a certain number of particles in one direction... and
basically the same number of particles in the opposite direction. The
idea is that things should be disappearing and appearing pretty much
everywhere equally. If you have a gravitational pull on you from all
directions equally, then you won't notice it.
