everyone told Chris Columbus to not sail out to sea because he would sail off the world?
Nobody told him that.
You homeschooled conservitards crack me up.
I'm sorry if my abstractions went too far over your head. Just as with Trump's dog meme that the media took seriously, I must continuously remind myself that I'm talking to tards. The ancient Greeks had estimated that the Earth was round. The real question in the 15th century was what was out there, how far could you go, could you get back, and what would you find? I think they actually believed they would sail into Asia.
THE POINT that escaped you my sizzle-brained friend is that one man (the few) proved the many wrong.
You went and looked it up, didn't you.
Yeah, you really walked into THAT one, didn't you? If you at all followed my posts closely outside of politics, you would have already known I almost became an astronomer and still teach it to this day, being one of the passions of my life. I could write a book about the history of archeoastronomy, the early astronomers from the Greeks, Ionians, the ancient Mexican civilizations. Their measurement of shadows at various places, their estimates of the curvature of the Earth, various other observations and extrapolations. Columbus was probably at least 1000 years past the last point where there were any doubts about the shape of the Earth, what they couldn't be sure of was the size, though one person came amazingly close.
But tell you what, any time you want to discuss astronomy, stellar physics, cosmology, stellar cartography and ancient mythology or evolution of mankind's perceptions and awareness of the Cosmos with me, go for it.
