Is the Universe Flat?

[Robh]

Just how reliable is the view that the universe is flat?

Thanks Rob!

Interesting.

Flat in this context applies only to the curvature in the "assumed" space time grid which is something to be looked at in a three dimentional view plus another (t) ... and flatness must then apply to a notion of what the universe is really doing...is it expanding forever or set to colapse one day...I think that is their flatness as we are talking about a geometric layout which somehow includes time and has little to do with the reality of the shape of the universe...or at least that is my take upon the matter.

If you believe many astrophysicists, it could be dynamic.

“The speed of light through space depends only upon the properties of the light and the properties of the space”, in that the properties of one photon are codependent upon the properties of another photon, and that the properties of one space are codependent upon the properties of another space, if an association exists between two particles.

Be hard to calculate if gravitation is dependent upon the energy density of the continuum, which is then dependent upon what's actually happening in spacetime. LOL
