yeah i thought this might happen.
because you see i just went through a big old, 1956, eddition of analytical and expertimental physics.
to my non physics educated mind i resoned that i should read the part about uniform circular motion and apply that.
so after reading the problem above my previous post and applying the equations of uniform circular motion i found in the big book besides me, i reached the conclusion that 2 different points on the rotating ring would travel at the same speed, i must say i only used the approxamation of the speed of light. (300,000km/s)
