    If time dilation occurs when the velocity of an object approaches the speed of light and relativistic speeds, do objects experience time dilation when rotating at relativistic speeds? Aren’t there pulsars or black holes rotating at relativistic speeds, how would someone’s clock near the surface compare to someone a couple AU away from the star not rotating with the object?

      On the surface of the body, you’re moving, so you experience time dilation. Physically this is no different than orbiting The body. The clocks built into GPS satellites need to be constantly adjusted for this reason.

      But the question how it works when the surface of a body rotates at relativistic speeds while the core is not moving breaks my brain.
