Georges,
I have studied your brief discussion on Dark and Luminous Matter, and have a few comments and questions:
1. Why do you assume that the ratio of luminous to dark matter can be represented as respectively as the surface and volume of a sphere?
2. While compactness is 3/R, this says nothing about *density,* which, IMO, seems relevant. Am I wrong here? [I see that density is inferred as the beginning radius of 72 meters.]
3. Why is it assumed that the universe expanded spherically?
4. Why is it assumed that the expansion occurred at the speed of light?
These are serious questions – I am not challenging your results, but primarily wanting to know the bases of your assumptions.
Regards,
Richard
