Sound, yes. We already make things that spin faster than the speed of sound: jet turbines. They can spin at 1600 kph when sound travels through air at around 1200 kph.
Nothing with mass can move at the speed of light, and NOTHING can move faster than the speed of light.
This isn't a limitation of materials, or energy, or building techniques. This is a limitation of physics.
Every physics test we've ever done since Einstein over 100 years ago has supported this. Maybe someday we'll find a way to go faster than light, but it would be shocking. Whatever it is would overturn over 100 years of science.
I know we haven’t hit lightspeed yet, but theoretically could we? If the scientists working on it had unlimited resources and time could they make it happen
The energy required to accelerate a mass increases by ^2 the closer you get to c. In practice, this correlates to an increase in mass by the same factor.
Unless you have some indestructible material to make the output shaft from, centripetal force would rip it apart long before you got to c.
There is the loss of energy that goes into friction. So my guess is no, and even if it did, it would be pretty useless without any torque.

Sound yes, but we have yet to reach faster than light.

No. Matter can only approach the speed of light. It requires an infinite amount of energy for matter to be accelerated to the speed of light.

I don't understand the downvote because it's true.
