Big Bang Busters

I Background radiation raises temperature everywhere in the universe to a few degrees above Absolute Zero. Big Bang couldn't do this level of homogeneity. Besides the Universe is too vast for each part to have had contact with all other parts II A good illustration goes thus: a heater in a cold room, or any source of heat, will eventually reach all space in the room and a erage out the temperature. But The Universe is no small, or huge room. The was no time with the Big Bang to allow "eventually" evening out the heat in the Universe. III: the solution The problem is labeled THE HORIZON PROBLEM. The answer centers on Someone or Something having finetuned the universe from the very beginning. No random process could achieve this ... But we want to keep our Big Bang. Another "solution"* us the Theory of Inflation, that allows the Big Bang to hang or bang on. * Earlier in January 2022, I did write on Inflation Thoery of the Universe
