G -> H -> ... -> SU(3) x SU(2) x U(1) -> SU(3) x U(1).

Here, each arrow represents a symmetry breaking phase transition where matter changes form and the groups - G, H, SU(3), etc. - represent the different types of matter, specifically the symmetries that the matter exhibits and they are associated with the different fundamental forces of nature

"Nothing to me would be more poetic; no outcome would be more graceful ... than for us to confirm our theories of the ultramicroscopic makeup of spacetime and matter by turning our giant telescopes skyward and gazing at the stars,"

Greene said.




Peter Woit:

Brian Greene was in the audience and somewhat objected to this. Brian's point of view appears to be the more traditional one that people should just try and cook up vacua with as many features as possible close to the Standard Model, and that once they've got such a thing it will have other implications for physics that can be checked. It seems to me that that kind of work has been going on for more than twenty years with no sign of success, but Brian still believes this will ultimately work out.

To me the idea of bubble dynamics is quite revealling when you place the context and question of the dynamics as underlying feelings(this is quite subjective). Much like GR, and these momentus occasions, that can move within our natures, as our comprehension grows. Time experienced in different ways, does this for us?:)It can still be a highly visula thing?:)

To not be mistaken, the questions materializes in the reasons why such dynamics may have been offerred in the same vain as GR, to see that this features becomes a signature of conscious effort, where what is being replaced, reveals some dynamics of the true vacuum?:)

So of course there are questions that need to be resolved. Some might not like to answer them and censor the blog of their own, so that blanket policies regardless of the question, is like who gives a **** about what you think in context of the larger picture of things. Of course they have their own agenda and have the right. It's their blog. I am quite greatful by such resistance presented, has forced me to expand here, where the truth of what I am seeing can be demonstrated.

But I have digressed some from the important question that is raised not only in Serkan's mind but mine as well. So resource info helps in perspective here.

Is QFT vacuum real?

Serkan Cabi:Almost everybody cite the Casimir effect as the proof of reality of quantum ground state of standard model fields. Lately it has become a commonsense especially in the dark energy literature, as an aspect deepening the problem.

So to me looking for an explanation of ths dynamics is a hard one to qualify as it suggested by some, that one wonders about the way early supersymmetrical idealizations have brought consideration to what emerges from these hottimes?



But there are other ways here, that having gotten a grasp of this elasticity of a membrane, that one can see how certain features are held too and others, are presented for further developement in the nature of those same psyches? Imagine introducing this memebrance and the elasticity. What has the mind grasped now?

Below Serkan helps to point out more info for consideration.

The Casimir Effect and the Quantum Vacuum

I have presented an argument that the experimental confirmation of the Casimir effect does not establish the reality of zero point fluctuations. Casimir forces can be calculated without reference to the vacuum and, like any other dynamical effect in QED, vanish as a→0. The vacuum-to-vacuum graphs (See Fig. 1) that define the zero point energy do not enter the calculation of the Casimir force, which instead only involves graphs with external lines. So the concept of zero point fluctuations is a heuristic and calculational aid in the description of the Casimir effect, but not a necessity.

This does not do away with the idea of what can happen within the confines of a vacuum, but ultimately, we realize that the speed of light remains the same, yet other dynamics when playing with physical things, can display wonderful intentions about about this elasticity nature?

Physically, the effect can be interpreted as an object moving from the "false vacuum" (where = 0) to the more stable "true vacuum" (where = v). Gravitationally, it is similar to the more familiar case of moving from the hilltop to the valley. In the case of Higgs field, the transformation is accompanied with a "phase change", which endows mass to some of the particles.

So it is a highly specialize vision that I had been moving towards that I wanted to make sure any bubble technolgies would encase all that we learnt. That we define the further reaches of what this bubble( K=0 before the crunch begins) might have encompassed? Revealled that outer value(K=0) of Friedman's equation and Omega in terms of what critical density would have expounded? In terms of the distance this bubble could grow, in this inflationary universe?

Outside this bubble universe, is a dimensionally filled universe that had grown as this bubble grew?

Such movement in propelling our universe to expression, seems quite a challenge, so having encompassed this larger view of reality, inverse square law would have exemplified the schwarzchild radius, determining the total expansive view of this cosmos?

You had to be able to confine this view and encapsulate it so that the total view developed through the phases of standard model production would have evetually helped us realize the wide scope this particle reductionism and cosmological endeavors had revealled with distances(large and small) joining?:)
