"Alright, Hubble said the radiation was left over from the explosion because the particles looked anisotrophic."
He didn't say that; he didn't even know about the anisotropic nature of the cosmic microwave background. (Kindly not that microwaves are not particles. If you don't even understand that much about the subject, kindly quit spouting off.) If I recall correctly, the discovery of the microwave background didn't even happen until after WW2, when radio astronomy really got going (due in part to there being a bunch of war-surplus air defense radars available for use). Later work on the Big Bang theory determined that there would be anisotropy, which was confirmed--in both presence and degree--by the COBE probe in 1991-92.
Your right, Arno Penzias and Robert Wilson. But still, whatever they gathered cannot be proven. And I will shut up, for now. You also didn't answer my question about anisotrophic the anisotrophic nature, only saying that it PROVES something. Nothing in a theory can be proven, unless you were able to reproduce it (the big bang). If it were, I would love to be there and see it (quite honestly).
