    The surface of the earth at the equator is moving at ~1600 km/hr in order to rotate fully in a day. If you teleport to the opposite side of the planet, you’ll still be moving at that speed but the surface there is moving in the opposite direction. You will now be having a very bad day.

      (Along the equator) in relation to the core along the polar axis. See how I did that? I filled in your implied point of reference. Isn’t that a pretty stupid reference compared to, idk, where your are standing now?

      How much is a 3 square feet patch of grass moving in relation to the one nearest you? Two points on a grid. It doesn’t matter if the grid is being translated around an axis, the two points are basically fixed and dont move in relation to each other.

        I see how you don’t understand reference frames. From any reference point, the 2 sides of the globe are moving differently. If you consider 1 side stationary, the other side of the earth is moving 3200 km/hr relative to you. If you’re at the core both sides are moving in opposite directions. I think you could teleport from one pole to the other and be ok. Reference frames by definition cannot be rotating.

          Incorrect. Any two walkable points on the earths surface relative to each other are for all practical intents and purposes static. The examples you gave earlier were relative to the earth’s axis.

            The earth is rotating bro. It is not static. that’s literally why there are jets streams and prevailing wind patterns. If you could actually use a rotating body as a static reference frame, the stars in the sky would be spinning around your reference frame every 24 hours. Any star doesn’t have to be very far away before it needs to move faster than the speed of light to complete it’s rotation (which is not possible). Go spin a basketball. I promise you the 2 sides are moving in opposite directions from any reference frame that is not spinning (bc reference frames by definition are not spinning)

              The Earth is Rotating around an Axis.

              If you take a pound of dirt and another pound of dirt and space them a few feet, or miles, or oceans apart, one of them doesn’t randomly start vibrating and floating around the other, idiot.
