Flatness Problem: To call a spade a spade.
=.
There are many different spaces: 2 dimension space, 3D space,
4D, 5D . . . .. .10D, 11D . . . . maybe more.
There are also ‘ closed’ and ‘open’ spaces.
There are many topological spaces too.
Question:
Which space has the Universe as a whole?
Answer:
It is fact: the Universe as a whole has exactly the
required density of matter to be flat.
The average density of matter in the universe (even
incorporating a dark mass and dark energy ) is equal to
or less than critical density and therefore the universe
as a whole is a flat infinite continuum.
==..
But the physicists refuse to admit this fact .
Why ?
Because they don’t know that to do with ‘ a flat infinite
continuum’. And they ‘ burned ‘ the real infinite flat
cosmological continuum ( using different abstract models )
to rid it of its infinite flatness.
And from Einstein’s time they discus about cosmological
constant that will close the flat- open Universe
into a close- sphere.
==..
The Universe as a whole is an Infinite Flat Universe.
Only in some rare places the Infinite Flatness is breaked.
==..
So, instead to say : ‘ It is fact: the Universe as a whole is flat,
they say: ‘To take the Universe as an infinite flat space - it is
impossible fact. There’s something wrong with the Universe. ‘

How is possible to understand the Flatness ?
How is possible to understand the Infinite Flat Universe ?
What is possible to say about a cold Kelvin space T=0K ?
==.
Flatness is a Vacuum.
Vacuum is an Empty space between billions and billions Galaxies.
Now (!) the physicists think (!) that the Universe as whole has
temperature: T= 2,7K . The parameter T=2,7K is not constant.
It is temporal and goes down. In the future it will come to T= 0K.
#
In my opinion this cold Kelvin space T=0K has old physical -
classical model so-called ‘ model of an Ideal Gas’.
Now we think that model of ‘ Ideal Gas is an abstraction’,
but this abstraction suit very well to another ‘ abstraction ‘,
to ‘a cold zero Kelvin space.’
These two models have negative temperature, and
in these two models there are ‘abstract ideal – virtual particles’.
And to have real model is needed something to change in these
abstraction models .. . .. and this change can be only quantum.
#
Now, let us put an elemenrary particles in the cold Kelvin space:
T = 2,7K ---> 0K. Which geometrical form they can have ?
The answer is: ‘ They must be flat particles.’
Why?
Because according to Charle’s law and the consequence of the
third law of thermodynamics as the thermodynamic temperature
of a system approaches absolute zero the volume of particles
approaches zero too. It means the particles must have flat forms.
They must have geometrical form of a circle: pi= c /d =3,14 . . . .
#
All formulas, equations and laws of ‘ an Ideal Gas’
is possible to use to the Infinire Vacuum T=0K.

P.S.
The universe is flat on the large scale, as per the scientific
evidence provided by WMAP.
Thus the universe was known to be flat to within about 15% accuracy
prior to the WMAP results.
WMAP has confirmed this result with very high accuracy and precision.
We now know that the universe is flat with only a 0.5% margin of error.
