Many cosmologists accept “Dark Energy” as representing today about 70% of all mass-energy of the universe and think it’s increasing every day. Where does it come from if the universe is all there is?
A universal model should be based on laws of physics, energy conservation and constants of nature being constant. Emmy Noether’s theorem leads to an expanding universe based on cosmic inflation, specified and explained in this article.
This model abides all requirements and observations of NASA and ESA and presents you a repaired Hubble law for far away galaxies and a corresponding distance ladder. It specifies the total universal Energy and explains the CMBR radiation change coming to us.
