Is the Universe Euclidean or Einsteinium ?

1.
In general the Universe is flat space.
The masses in the Universe are very few.
The distances between stars are very far.
What this means is that if you go into space far from massive bodies
and locate three ships far apart in a giant triangle, the angles of the
triangle will add up to 180 degrees, just as Euclid states in plane geometry.
2.
But Einstein ( GRT ) and others thought that the Universe was circle space.

Question.
Is the Universe ( as whole ) cold flat Euclidean space
or cold Einsteinium circle space ?

By AWT universe changes its nature with space-distance scale periodically like nested foam.

Sado, all trajectories are curved( Einsteinium ) but may appear
straight( Euclidean ) over short enough distances.

Sadovnik.
1.
"An implication of Einstein's theory of general relativity is that
Euclidean geometry is a good approximation to the properties
of physical space only if the gravitational field is not too strong"

Thus, if you meet with a strong gravitational field,
Euclidean geometry breaks down.
2.
The masses in the Universe are very few.
The distances between stars are very far.
So, most time quantum of light must go straight and
only meeting a rare star his trajectory will break down.
3.
The cold Euclidean space is Origen.
The Einsteinium space is Secondary.
The cold Euclidean space is Origen and it is Vacuum.
The Einsteinium space is Secondary and it is Gravity space.

Not the reverse.

It depends mostly on observational perspective. Inside of gravitational lens observer is deformed together with space-time, so he would see the path of light straight and space-time curved, whereas outside the graviatational lens he would stay in flat space-time, so he would see the path of light curved instead.



Because no observer can exist outside or inside of gravitational lens completelly, both these perspective would be always mixed, from this the quantum uncertainty follows.

In AWT the answer depends on the observation perspective used. We can compare it to the observation of landscape in fog or spreading of light through foam. From outer perspective foam or fog is quite homogeneous, but from inside every source of light suffers dispersion, so that light path never reach infinite distance here. We can imagine, every source of light disperses by density fluctuations of vacuum, which manifests itself like cosmic microwave background.

We can compare it to the situation of wave spreading on the watter surface. From outer perspective, which is mediated by sound waves spreading through underwater, the water surface appears flat. But the surface wave suffers by dispersion on density fluctuations of watter, which are caused by Brownian motion of water molecules



As the result, ripples at the water surface spreads by slower and slower speed, so that the rings speed decays to zero and they're becoming more and more dense gradually. The answer is, from outer perspective Aether is of infinite mass/energy density and as such it's always flat. But from limited perspective of inner observer the light always suffers by dispersion, so it spreads more and more slowly, which we can interpret like dark matter cloud, surrounding every massive object. And the space-time defined by such light spreading is always curved. The duality of insintric and exsintric observational perspective is quite important in AWT and it affects most aspects of our observation, for example uncertainty principle.

So that my answer could sound: Universe is flat from perspective of gravitational waves which spread in superluminal speed, but it remains always curved and closed from perspective of light waves, which are spreading in limited speed.
