I Angular Velocity: Can a Body Move Faster Than C?

[Sandeep T S]

When I rotate my head with 1rad/s , I can see a body which 350000km away have velocity greater than c.is that possible?

By what logic will the body appear to have velocity greater than c? What you see is the light emitted by the body about 1.2 s earlier.

Just rotate head in night sky, you will see stars are rotating, v=r ×omega

Have you tried turning your head at 1rad/s? Was it possible?

The speed of light is constant and invariant in inertial frames of reference. A rotating frame is not inertial.

Please try again. That (long) thread should answer your questions about this thought experiment.

We spent a lot of electrons on that thread, so this duplicate of it is closed for now.
