I noticed some folks in c/Conspiracies/p/15IXWXnIo6 arguing about the shape of the Earth. It doesn't look to be in bad faith, so I create this post for anyone interested.

Personally, looking at the Sun (ouch) and the Moon is enough for me.

The point is it makes absolutely no sense for an infinite vacuum to not suck all of the air off of earth.

Nope. Shitty understanding of physics. A vacuum isn't a force, it's just empty space. A gas particle sitting in a vacuum has no reason not to move towards a source of gravity.

Yes it does. The infinite vacuum it’s sitting next to

A vacuum is literally nothing. There's nothing to stop gravity. You seem to think things move for no reason. You need a force for something to move

Yes, a vacuum is literally nothing. Gas expands to fill its container. “space” is an infinite vacuum. So the container is an infinite vacuum. There’s nothing keeping the air contained on the spinning ball moving thousands of miles per hour.
