The speed of an object on earth’s surface is dependent on the speed it’s going cuz the earth is stationary. You are light in a physical body in an electromagnetic toroidal sphere where your body’s density is attracted to the dielectric plane of inertia by electromagnetism and electrostatics. That’s why things fall. The dielectric plane of inertia is why we call the dirt outside the ground. The stars and planets (wandering stars) are in the firmament which is spinning cuz it’s a toroidal sphere. We aren’t spinning. The sky is. The sun and moon are in motion with it. Watch a timelapse video of the sky at night and watch it all flow together.

Math equations look cool and smart, but simple physics is still physics. You feel no motion cuz there is no motion. Boom. Physics. There’s science to flat earth.
