All you can say in this site's defence is that it, rather than reality, occupies the warped minds of some of the planet's most twisted people; gods know what they would get up to if it wasn't here.  In these arguably insane times, any lessening or attenuation of madness is maybe something to be thankful for.

Yeah, Regret is right, I got confused there. One particle has negative energy and goes in, the other is positive and gets emitted as the Hawking radiation.

Which makes no sense if I want the vacuum energy to average to nonzero...
Aaaaaaaagh :asplode:

maybe it averages to zero everywhere except around a high gravity source.

why do you want the vacuum energy to do anything?

Well not that I wanted it to, more that reading about it suggests that it should.
Be what you would seem to be - or, if you'd like it put more simply - never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise.

In order for there to be an average of zero, wouldn't half of the particles have to have negative mass-energy?

Also, seems like this has something to do with Hawking radiation.
or be out of phase because of the wave/particle nature.

Um... As far as I can tell, they come from nothing.

Not exactly satisfying, but that's the universe for you.

Quotethe vacuum energy and the virtual particles are the same thing, neither one causing the other

So, its just latent energy that happens to manifest as matter.

Actually, that's rather satisfying, and fits in with my worldview quite nicely. It might be made up bullshit still, but its okay made up bullshit.

yeah thats a nice way of looking at it.
As a kid did you ever do the piece of string thing where you put lots of loops in it but dont thread it, when you pull the string the loops all vanish.
All the mass in the universe probably has its its opposite somewhere and could eventually neutralize to a nice harmonious nothing.
