tennis ball at high rotation If the earth is spinning at 460 meters per second, or roughly 1,000 miles per hour, and gravity is a weak force, when why don't we fly off the surface of the earth?

Centrifugal Force


I've heard from a number of flat-earthers that the spinning globe doesn't make sense because the objects would fly off of it. Just like a merry-go-round, the spinning creates a centrifugal force. They usually follow that up with irreverent numbers like the fact that the Earth has a rotational speed of around 1000 mph. But they fail to understand that linear distance traveled is not related to centrifugal force. Example video below.

If you talk to enough flat-earthers you will discover that two theories dominate the gravity discussion. The first theory is Universal Acceleration which has already been discussed by WTC. The second theory is less developed but claims that gravity does not exist and that objects rise and fall because of density. This density theory is what this post is about.
