what diameter would it have to be for the outer edge to achieve light speed?
Also, if you were to extend the diameter by a further meter, would the outer rim exceed light speed?

the rotor blade length/speed was limited so as to keep below the speed of sound or else the whole mechanism would shatter. Not sure if a disc would survive it.
