Proof the Earth is round

[VonBonfire]

Not really. Climate change can and has been argued from a POV that has no cut and dry proof as evidenced by “ Experts” on both sides of the issue. Both Russia and the US would have had to go to extreme lengths using technology that didn’t exist to fake space photos from 1969.

It's still spun as something real even by enemy nations so you are just a denier unless you can admit global conspiracy is possible. Kind of like covid. Kind of like heliocentric earth theory. Daring to question the official narrative of any sorts puts you in a different camp. Welcome.

On a flat earth I suppose you theoretically could.

On a globe earth the mountain would need be over 484467.3784 feet tall for you to see it's top because that is how much curvature blocks your view from the top of the 630 foot arch 888 miles away to the nearest of the rocky mountains per google and an earth curvature calculator. That's 91 miles of curvature, and that's with your vantage point at the top of the St. Louis arch. Standing with your eye 6 feet off the ground beneath the arch that's
515940.5896 of curve, or 97.7 miles of drop from your location.

Glad you are at least seeing things my way. Curious as to why it can only be theoretical though. Would that be because the human eye can only see so far or because you believe telescopes are fake? Being serious, not coy.

I appreciate that you did all the math for this particular exercise. Actually, I'm glad anyone in this thread can do this math. I can't. I mean, I could if given a formula, but I find math extremely boring which is why I usually do not include math in my observations or discussions

I can barely count in 4/4 as it is

But yeah, back to your point about the mountain being 484,xxx feet high in order to see it. I wouldn't expect to see it as is because the earth is a sphere - like most every object in the universe.

You're misunderstanding what is going on. That's the wrong formula. You need to calculate the length of two arcs. The first arc follows the curvature of the earth according to the earth's radius. The second arc has a larger radius because it represent the height of the bridge deck up on the pillons. Having a larger radius means it has a longer length.

Think of it this way. The earth has a certain circumference according to its radius. If the earth's radius was 100m (or whatever) larger being the height of an imaginary bridge right around the earth then it's circumference would be bigger. A bridge however does not go right around the earth. It's just an arc however it's still longer over a given angular distance.

Well stated
