Inflationary Theory out of thin air?

[Mike2]

Its a good point, like i said I am simply reiterating what I've read. As i see it though they weren't really one force as such, rather they were grouped together because under the conditions of the time they all acted the same. As these conditions changed so the forces that decoupled exibited different behaviours and effects, thus affecting the world around them in a way that affected the overall entropy.

As I understand it, the other forces diverged from the one force through some mechanism of symmetry breaking. And I've suggested that h-bar was larger during inflation when the forces were one. So I have to further wonder if the required symmetry breaking process could be accomplished by a reduction of h-bar. Since h-bar has the units of an action, a larger h-bar argues for more invariance in the action integral. If the minimum possible action is larger, then changes in the action integral with respect to variables within it will still be within that minimal amount of h-bar and thus not noticed. So if the minimal possibe action becomes smaller, then invariances will have a more noticeable change in the action integral, and previous symmetries may disappear. Any thought on this anyone? Thanks.

The problem I see mike2 is a scaling h parameter is irrelevant prior to the emergence of spacetime - assuming spacetime is emergent. Albeit might be a factor in a background dependent model. BTW, I have a link you might find interesting:

What do you suppose spacetime emerges from?

From what I can gather, h-bar shows that space and time are related in a spinfoam type QFT to matter and energy. The delta-energy*delta-time>h-bar indicates time (a spacetime property) in relation to energy (a particle property), whereas the delta-momentum*delta-position>h-bar indicates space (a spacetime property) in relation to mometum (a particle property). So it seems spacetime is inexerably connected to vacuum energy (virtual particles).

If h-bar were zero it seems spacetime would be exactly correlated with energy-momentum. But if h-bar were larger, then expansion (of spacetime) would not be well correlated with vacuum energy (virtual particle properties).

A universe from nothing would be my guess.
