These ideas are not mine, but I will try to add something some time from now.
"I'd like to talk about what I think is already proven to happen to the
gravity of the universe when we make particles from negative-energy
states, and the effect that this has on the thermodynamic structuring of
our universe.
In quantum field theory, a postiron has the same gravitational
properties as an electron because the negative energy states are really
the postivite energy states of antiparticles. That means that pair
production makes no difference to the gravity of the universe and even
general relativity supports this conclusion if the universe is infinite,
since gravity is essentially curvature that caused by the energy that's
contained in a region of space. In this situation, pair production
changes this energy from photons to the mass of other particle pairs,
but the energy curvature and gravitation of the universe remain the same.
Okay, but what happens to the gravity of the universe if the universe is
finite?
Doesn't this drastically change the effect on the gravity of the
universe when... rho+3P/c^2=0 in a finite universe?
You can't take vaccum energy from a finite universe and then contain the matter energy-density to a finite region of space without increasing negative pressure in proportion to the local increase in positive gravitational curvature, because the graviational acceleraton is zero when the density of the vacuum is -0.5*rho(matter).
You have no choice but to condense this energy in order to attain the
matter density when the negative energy states have negative pressure,
because... P=-u=-rho*c2
So there is no net change on the gravity of the universe, because the
effect is two-fold... an increasing antigravitational *effect* is offset
by increase in positive gravitational curvature.
But that means that tension between the vacuum must increase as particle pair creation drives vacuum expansion if the universe is finite, and the offset increase in both, negative pressure, and positive gavitational curvature necessarily holds the vaccum flat and stable as it expands, so it cannot run-away! Increasing tension between the vacuum and ordinary matter leads to a prediction that the integrity of the forces that bind this finite structure will surely eventually be compromised by this process and we will have another big bang.
So the second law of thermodynamics is never violated when the entropy of the universe always increases via the described perpetually inherent thermodynamic structuring, which enables the universe to continuously "evolve"."

Looks to me like a great discovery has been made... heheh... ;)
FYI, you can edit out those page breaks if you want to.
There are four very short posts attatched to this that also make this more clear.

Island,
I was planning to fix it. Yesterday I was in a hurry. I will try to link to your other work, when I understand better what you are proposing.
Thank you very much Eduardo, and I would very much recommend the articles that I have been linking to, as they explain the connection to the negative mass solutions that this has. The problem that I typically run into that makes physicists refuse to look deeper into this, is that they assume that all of this has already been settled by quantum theory, and they think that quantum gravity cannot be reconcilled with a field theory.
But that is not the case, in this case, because, as with electric charge, the normal distribution of negative energy does not contribute to pair creation. Only departures from the normal distribution in a vacuum will isolate enough vacuum energy to produce virtual particle pairs. These pairs can be converted into real particles given enough energy, but they do not have negative pressure, negative energy, (nor did they ever have negative mass, it just looks that way because of the "antigravitational effect" that negative pressure elicits), once that they are condensed to become localized departures from the field.
You litterally rip real holes in the vacuum when you make particles from Einsteins vaccum energy, and the void that you leave necessarily increases negative pressure.
That drives expansion.
I am reading Aharonov and Tollaksen. They clarify weak measurements in QM, that seems to be another way out of the "limitations" imposed by Planck's constant.
I have to admit that I've developed a very healthy aversion to causality-dodging, explain-it-away "physics", since I fell into this mess.
According to everything that I've learned... "God"... does not throw dice.
The following excerpt is from Aharonov and Tollaksen recent article:
"Finally, we have also used these considerations (Time Symmetric Quantum Mechanics) to probe the axiomatic structure of QM. Traditionally, the uncertainty of QM meant that nature is capricious, i.e. "God playing dice." A different meaning for uncertainty can be obtained from two axioms: 1) the future is relevant to the present and 2) causality is maintained. In this program, uncertainty is derived as a consequence of the consistency between causality and weak-values; in order to enrich nature with temporal non-locality, and yet preserve cause-effect relations, we must have uncertainty."
