nothing says that CMB radiation was radiated from one point, it is just said to be the oldest form of radiation and that it fills the universe,
big bang doesn't say the radiation came from one point. in the early universe, matter and radiation were sort of intertwined together, and were not able to separate from each other until the universe has expanded enough. this moment of separation is called 'recombination time', and this is when the radiation was able to move freely from the matter. at this point, the radiation is almost uniformly distributed throughout the universe, so if this were true, we should expect to see the same blackbody spectrum of radiation coming from all directions at equal strength. but if the universe has been expanding for billions of years, we would expect this radiation to be greatly redshifted to lower frequencies. lo and behold,
after the big bang theory predicted we should find this radiation, it was discovered that it did indeed exist. we do see a blackbody spectrum of radiation coming uniformly from all directions, and it is redshifted to low frequencies as expected. the CMB radiation therefore is evidence for the big bang. that's the way evidence works in science - fullfillment of predictions of a theory.
there's no proof that the universe itself is expanding, only that the galaxies are gradually moving furthur away,
yes, everything is moving away from everything else at much the same rate. what's the difference?
there's no proof that everything will eventually contract.
i never said that, i think you misunderstood me. i was asking you to
imagine the reversal of time, and look at the universe. if you go forwards in time, the universe is expanding. if you look at it in reverse, it's contracting. get it?
the only TRUE evidence of the big bang is that most galaxies are just giant black holes from large stars...
i don't see why this would be evidence for the big bang. black holes would have formed many millions of years after the big bang.
but you have to understand that there's many of them, and only one star makes one black hole. So there's no evidence of a super star creating many black holes, or else one regular star would give off many tiny black holes
i'm not sure i understand what you mean here.
