What is cosmologically constant?

[GeneralDadmission]

Why is the compression value of vacuum not considered the cosmological constant? Is it not vacuum tension that distributes kinetic energy?

[GeneralDadmission]

Didn't think that would actually be difficult to answer.

[Mordred]

The cosmological constant is roughly 6.0*10-10 joules per cubic meter.

 

Even a vacuum must have a cause, vacuum states is a thermodynamic property of pressure relations. In quantum mechanics the lowest possible energy state due to the quantum harmonic oscillator which incorporates the Heisenberg uncertainty principle

 

[latex] e=\frac{1}{2}hv[/latex]

 

However this causes 120 orders of magnitude too much energy.

 

In terms of strictly pressure ie a high energy region spreading out to a lower energy density distribution. Well this doesn't work either. The reason being is that it isn't homogeneous and isotropic. Also as the tension or pressures equalize the differents in the two vacuum regions is reduced . This would lead to a non constant value that reduces as the two regions stabilize.

 

Lol side note this was a model I pursued for some time. I was able to disprove it via the problems I just mentioned.

 

The three main problems is ",What keeps the cosmological constant equal"." Why is it's energy density so small" why is it homogeneous and isotropic"

 

The answer that satisfied the above Will probably entail a thermodynamic process.

 

There is some hope that it may involve the Higgs field but further research is needed to confirm that.

 

Some people try to suggest the universe expanding into some void. This doesn't work either. Let's assume there is some magical outside just as a thought experiment. The regions closest to the outside would equalize first then the equalization (tension) would balance out progressively toward the center at max the speed of light. This is a preffered direction and location.

 

Measurements agree the universe has no preferred location or direction. (Homogeneous and isotropic)

 

Nor do we know if the universe is infinite or finite.

Here is some material to clarify some details

This has a lot to do with why I prefer the matter/antimatter model. It treats the vacuum as a particle with it's own velocity. The velocity of one is interdependent to that of the other. There is no equalization between the two except in the case that the universe leads to a Big Rip, in which case there is a point at which either field would reach a point of total uniformity of internal relativity with subsequent collapse between the two fields.

 

I will need some time to absorb your response to address it further. Cheers.

Here's the crux we include antimatter and matter in our thermodynamic models. See chapter 3 of the latter article

And I was hoping to reach a resolution by the morning. How long did it take you to disprove your modelling? This hobby could keep me going indefinitely!

[Mordred]

Roughly three years I was stubborn

WMAP 2003 data effectively clinched it.

I'm hoping you've answered all my physics related questions but only time will tell.. Cheers Mordred.

Can you identify for me what is specifically significant regarding the energy density's energy level and what is defined as equal? In regard the second passage why would a preferred direction and location be measurable spacially?

 

ie; If time moves in the direction of gravitation the preferred direction is err,,, futureward and the preferred location is now.

 

This would be a fair point to raise the question of whether it is simply assumed that hydrogen stabilised first before reionization? I've had to assume that the basic planck timeline description of the BB epochs available on wiki are a simplification of modelling with greater definiton. I cannot say the model I constructed for the period between BB inflation and reionization in order to get an understanding of relativity is as vague as the basic descritpions provided of the forces seperating in wiki type references.
