An alternative to the "big bang", “black hole”, “ideal gas”
=
In the 1973 the Universe was in the condition T=2,7K. ( Nobel prize )
Today in the 2014 this condition is a little less than T=2,7K
and " tomorrow" this condition will be T=0K.
Therefore I will say:
It was, is, it will be forever an infinite, eternal, absolute reference frame T=0K.
On this infinite scene there are located gravity systems
on which human tries to understand the reality.
==
In the T=0K exists some kind of "virtual" negative imaginary particles.
These imaginary quantum particles are as real particles as positive Newtonian ones.

Kirchhoff's black body - light go in and don't come back.
Black holes - light go in and don't come back.
Zero Vacuum - light go in and don't come back.
===
Black - holes have temperature about absolute zero
(60 nanokelvin - 60 billionths of a kelvin).
" Ideal Gas" has temperature T=0K.
The Cosmos as whole has temperature T=0K.
===
My conclusion.
a)
Kirchhoff's black body, black holes , "ideal gas" are models of zero vacuum.
b)
All laws of an "ideal gas" and "quantum theory" can be used
to explain the initial / primary conditions of the Existance.
c)
It seems that in the future heat death of the universe can come.
(according to big bang)
But thanks to Planck's and Hawking radiations
( vacuum fluctuation, tunneling barrier )
the Universe can escape heat death.

It may approach 0K as a limit, but it will never be "0K". That is a theoretical number that is basically impossible to reach, you can get as close as you like.

 

The Cosmos as whole has temperature T=0K.

So which bits are below 0 degrees K ??

By the “theory” we were educated:
“ if we cannot observe physical phenomenon then it doesn't exist.
We can ignore this phenomenon. “
=.
There are two fundamental constants in nature: T=0K and
constant speed of photon: c-1.
1)
We cannot reach constant speed of photon c=1 but photon can
and ( thanks to Michelson ) it was observed and therefore it was accepted.
2)
We cannot reach T=0K, we cannot straight observe phenomena in T=0K.
Any instrument does not fit.
But this doesn’t mean that this continuum is abstract.
The “vacuum fluctuations / transformations” show that T=0K isn’t abstraction
and “virtual particles” exist there and they can change situation for observation.
3)
One fundamental constant ( c-1) after many years of doubt was adopted.
Sooner or later another fundamental constant of Nature: T=0K would be adopted too.

Not really, quantum foam sees to that. It is an impossible condition.

"quantum foam " . . . ? ?
=.
Quantum foam is theorized to be the 'fabric' of the Universe,
but cannot be observed yet because it is too small.
Also, quantum foam is theorized to be created by virtual particles
of very high energy. Virtual particles appear in quantum field theory,
arising briefly and then annihilating during particle interactions in such
a way that they affect the measured outputs of the interaction,
even though the virtual particles are themselves space.
These "vacuum fluctuations" affect the properties of the vacuum,
giving it a nonzero energy known as vacuum energy, itself a type
of zero-point energy.
However, physicists are uncertain about the magnitude of this form of energy.[8]

You are incorrect. Google Casimir effect.

 

All particles have a minimum of 1 wobble. Particles can never reach 0. But 0 is certainly a reference.
