Answer 2

Curvature of the Earth

Most of our daily experiences of motion are related to one of the four fundamental forces of nature: gravity. Gravity is spherical - if we pick a random point on the planet, the gravitational force should be the same as any other random point (let's assume the Earth is a perfect sphere for now).

Consider me walking on the surface of the Earth. I would be unaware that the Earth is spinning without external reference points like stars and the sun. If the Earth stands still, I would walk just the same, because when I walk I am interacting with the ground below me, which is part of the Earth; I am not interacting with Saturn or any other planet.
