Would you eat a piece of meat that the author of one of your sources had told you was kosher, when you yourself had seen it taken from the carcass of a pig?
Yes, if the posek declared it kosher after having heard my testimony to that effect.
None of the people you cite lived long enough to hear of the discovery of the cosmic background radiation, which proved beyond any doubt (1) the big bang, and (2) the ancient universe. We cannot conjecture what they would have said had they lived into the 1960s and studied the data carefully.
Thank G-d for that. They would have said everything they had said already without all that sheker.
