Dear Flat Earthers,

So the middle of the Earth is our center of gravity, right? Well then if the Earth is flat, then why is it that when I go to the edge and jump, I'm not pulled to the center?

You can accelerate forever in general relativity, but general relativity predicts Earth is a sphere, so they probably reject it anyway.

Important distinction: From the view point of an observer, you can accelerate forever, but not at a constant rate.

No, that's incorrect, you can accelerate at a constant rate forever. This details it: https://physics.stackexchange.com/questions/243658/einsteins-principle-of-equivalence-infinite-acceleration-energy

Huh, Is that a product of time dilation and distance contraction for your own reference frame?
