Finitism and Cosmology

I did the math using the data in the table you posted a few posts back and got a volume for the universe of 4x10E79 m3. That is for 10E10 galaxies of 10E11 solar mass. Is this a reasonable volume estimate for both the MM&BB models? It is not all that much smaller than my original 10E80 m3 sample so I guess it is not right because of the shrinkage as it receides back to the original event. But, even so this estimate has 10E78 protons or 1 proton per 40 cubic meters which is too little mass and too much volume.

I haven't checked your math, but those numbers (10^10 galaxies, 10^78 protons) are the usual ones I've seen quoted. The rest of the BB universe is supposedly "dark matter". The MM universe is infinite, and has no volume shrinkage as you go back in time, so your original numbers would be more accurate for MM. However, gravity does not operate on such large scales in MM, so these figures have no special significance for it. -|Tom|-

The thing about the estimate is the speed of the expansion is the speed of light and that is not what the Hubble Constant shows. I fully aggre gravity is not a factor in the large scale structure of the universe.(if that is what you said)
