1.) Galileo was not "nearly executed".
2.) not because Pope Urban VII rejected Galileo’s science, but because he (obstinately after many opportunities) taught his (then unproven) theories as fact. The rule in science was unproven theories were to be taught as unproven theories, not as fact. Galileo had the support of many influential churchmen but was a horse's ass who intentionally antagonized everyone around him.
Galileo's punishment? Confinement to a luxury apartment with his equipment where he could continue his research.
Really?
Giordano Bruno was tried by the Inquisition for his “heliocentric heresy”, but he did not “recant”, as Galileo did.
Bruno was burned at the stake. Perhaps he should have “recanted”, too.
