re: #105 EPR-radar
The competing theory to the Big Bang model was a steady state model for the cosmos that would have no beginning and no end. en.wikipedia.org
One peculiar feature of steady state cosmology was that its main hypothesis was continual creation of matter in the universe from nothing.
Discovery of the cosmic microwave background radiation was pretty much the death blow for steady state cosmology.
I was going to mention that but decided to stop where I was at. I think finding the cosmic microwave background radiation is one of the more remarkable findings of my lifetime. Esoteric, but so amazing.
