If the world was flat, would it be possible to see Mount Everest if it was on the other side of the Earth on a clear sunny day?

And you cannot see the top of Everest from the surface more than 280 miles away either, because the Earth is a sphere.

Well, no, not from everywhere on Earth, my friend. As many people have pointed out in the comments, the atmospheric gets pretty thick at distances comparable to the distance obscured by Earth’s curvature. That's why flat earthers love to harp on that point.

You cannot see farther than about 280 miles across the surface. Ever. No matter how hard you try. The only way, and I mean ONLY way to see farther than 280 miles is to fly.

If the Earth were flat, you would think the telescope on top of Muana Kea should be able to see Everest. It can't. It can't see Mount Shasta in California. It can't even see Kawaikini on Kauai. It cannot see another mountain top more than 280 miles away because the Earth is a sphere.

And if you can see farther from the air, why can’t you do it on the ground??

OP: “If the world was flat, would it be possible to see Mount Everest if it was on the other side of the Earth on a clear sunny day?”

Should I have left it alone and kept quiet? I came out as gay to my adult kids last week. Age 61 married 15 years, divorced for 20. I feel so guilty for ruining their lives by living a lie.

And yes, at that distance, the haze prevents line of sight too. But we know the curve exists in many other ways.
