Flat earth or round earth?

Tom is staring at the sky, squinting.

Tom:" You ever just… look out there and think, “maybe the Earth isn’t round"?

Arnold: "Oh no. Not you too."

Tom! "I mean, look! It’s flat. I can see everything. No curve. Just… ground".

Arnold: "Tom, that’s called "your field of vision." "You’re not an astronaut; you’re sitting next to a hot dog stand."

Tom: "Okay, but if the Earth is round, why don’t people fall off the bottom?"

Arnold: "Gravity. It pulls things toward the center of mass".

Tom: "I thought gravity was just a suggestion".

Arnold: "And I thought you passed high school".

Tom: "I did! Barely! But I passed"!

Arnold: "Look, the Earth is round. Not because I believe it, because physics, satellites, space photos, airline flight paths".

Tom: "Yeah yeah yeah,

Arnold, but… what if it’s just a really big pancake"?

Arnold: "Then I’m flipping you off it."

Hello! Listen closely!
