Why do aircraft with turboprop engine have black painted anti-icing system? It is almost impossible to explain by the steady state theory, whereas the big bang theory predicted its existence. Penzias and Wilson, two radio astronomers in the United States, registered a signal in their radio telescope that could not be attributed to any precise source in the sky. We make theories to be able to successfully predict observations before we have them, which the Big Bang theory did for the CMB, and to be able to quantitatively understand those observations, which the Big Bang theory does for the CMB. 4 Ways Artificial Intelligence Changes the Game for SEO.

There is now direct evidence that the CMB was hotter in the past and by exactly the amount predicted by an adiabatic expansion. But framed properly, the question is easy to answer-- the evidence that the Big Bang theory is the only theory that is successful at predicting the existence and quantitative aspects of the CMB is simply that the existence of the CMB was predicted, before it was observed, by only one theory, and that's the Big Bang.

Breath Of The Wild Item Map, Ralph Alpherin. The existence of such anomalous regions, resulting from point-like sources at the conformally stretched-out big bang, is a predicted consequence of conformal cyclic cosmology, these sources being the Hawking points of the theory, resulting from the Hawking radiation from supermassive black holes in a cosmic aeon prior to our own. What type of light does it look like now?
