Makes sense.

It’s a hoax.

Probably is but I’ve met some who sincerely believe it. The problem is that there’s no evidence you can present them that isn’t a government trick. As a thought experiment I tried to come up with irrefutable proof the world is round.

Year before last, I flew from New Jersey to Malaysia. The entire flight, the horizon appeared as a curve. Now, I understand that does not in itself prove a round Earth; this does: the curvature remained the same the entire trip!
You see, if the planet is a pancake, from the air it would look round, oval or straight depending on the angle you’re seeing it from whether straight down, oblique or on edge respectively but since the shape of the horizon didn’t change it has to be spherical because only a sphere maintains a constant curvature regardless of what angle you view it from.

Of course, but a lot of people believe in hoaxes.
