On: Why can’t I go faster than the speed of light?

What would happen if you had a very large rotor of let's say 50.000km in diameter. And let it rotate at 1r/s. The inner part would only move at very low speed and the outer part at near lightspeed. What kind of time dilation effects would be seen? If you would sit on the tips for a few days and then stop the rotor, travel back to the center, you would see a very old one right?

I think veritasium discusses that as well. Essentially at relativistic speeds there are no chemical bonds that can hold and the device shreds itself.
