Next he'll claim that the International Space Station is a hoax too.

Is that a UFO in the top part of the picture?

no doubt

I strongly encourage you to try this yourself if you live close enough to a port - this is science from first principles, and all science is ultimately based on common sense and first principles.

The issue of atmosphere shouldn't be hard to understand - even if you don't like the term gravity you will notice that you don't float off into space, and neither does your car, nor the air that surrounds us. These things have mass. We can see that things with mass don't float off into space, and we call that gravity, but if you don't like that term you can call it Fred.

ships don't actually disappear from the ground up. it kinda looks like they do, but what's actually happening is as the ships goes further away, a mirage of the top of the ship appears at the bottom of the ship. in a lot of cases, when they get really far out, they look like just floating masts.

it looks like some people have basically said what i wanted to get out though, which is that a gaseous system within a vacuous expanse does not exist other than in the case of earth.

that's good.

next question:

why can't a plane fly into the rotation of the earth to shorten its flight times?

that would be detecting the curvature. much different than seeing it.

and just to test your logic about horizons a bit, would the horizon not still exist if the earth were flat? to me the horizon is just where the sky meets the earth.

Pure genius.

No, when you look at the horizon, you are literally seeing the point at which the surface of the Earth is curving away from your line of sight.

I'd imagine that would depend on how far away from you the surface of your imaginary flat plane stretched and how much the thickness of atmosphere at that distance diffused light.

okay, but you can't see the actual curve itself, from left to right. so you can't see the curve. call it semantics, but you can't see the curve.

if the earth were flat, and went on infinitely in every direction, would you see a horizon line?

Because you don't understand physics.
