Spinning faster the the speed of light

[flash11]

if a disc was spinning faster then the speed of light... would you be able to see it? and would it make a sonic boom when it past the speed of sound?

No, nothing can travel faster than the speed of light, so asking whether or not you could see it is an illogical question.

well would it make a sonic boom when traveling faster then the speed of sound cause since its spinning I am not sure if the sound waves would compress?

Some fans spin faster than the speed of sound, such as helicopter blades and yes, they make a sonic boom.

thats interesting (: but suppose each blade was connected like disc or CD shape then would it make a sonic boom cause would it be able to run into the sound waves it creates?
