Flatness Problem: To call a spade a spade.
. . . etc.
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.
Which space has the Universe as a whole?
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 .
Because they dont 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 Einsteins 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 : we need to call a spade a spade
they say: If theres nothing wrong with me then,
maybe theres something wrong with the Universe.
