- cuteboy19 5y agoImagine that you live in a starless void. Could you still prove that the earth spins? Yes, simply point the gyroscope towards an arbitrary direction and repeat the same process as in the proof. If the earth doesn't spin, then the gyroscope would point at the same direction always. But if it does spin then it would show those circles.
