Serious questions, seriously.

What about curdled milk?

Back in post 5 MrMe gave us those images that science has assembled from the knowledge gained thus far... The mainstream view.

Some milk is homogenised which is homogeneous... but would cause a environmental issue if used to fill a swimming pool...

Neverfly's curdled milk shake would stink... Sponge like structure is good enough for my understanding...

At the time of the early expansion there was never a opportunity for gravity force to act upon the universe as its expansion was explosive.

Which is not suggesting it was a 'explosion', but for the being near it. Was one.

Solve the riddle of what is 'Dark Energy' and you win the Noble prize... WE do not know do we.. ?

Energy <aka light energy> = presence of light...you can see it; dark energy = absence of light...you can't see it... [rotflmao]...you can send my Nobel to ....

I would argue that it's homogeneous with respect to the fact that whatever clumping we do see forms no repetitive pattern. It appears to be random.

I think some think homogeneous means that everything would be equidistant from everything else. That would not only form a pattern, but statistically speaking it'd be ridiculously unlikely.

It appears as if not everyone agrees with you...probably starting with Einstein...see [1105.0815] Centrifugal cosmological repulsive force in a homogeneous universe <-- Link.
Another paper states in part: However, all the inhomogeneities in the density distribution, when averaged over hundreds mega-parsecs, are very small and can be seemed as the per-
turbations of the homogeneous background. This paper may be found at [1102.5395]Proliferation of the Phoenix Universe <--Link.

You are most welcome, Mr. McCarron...and, please, call me David (or Dave) as Mr. Eaton is my father....
