thanks for the link ghwell jr its sort of helps i understand that spinning a disc up to that sort of speed is near impossible but if it was. what would the observable effects be. but thanks all the same :)
this is my first post so please be gentile with me
what would a wheel or a disc turning at a speed approaching that of light look like
my knowledge of the subject it quite small
but say the disc was rotating clock wise then looking at it from its right side would the top half look...
