Heres a wondermant about centrifuges and near light speed. Now if a record on a recocrd player spins at 33 1/2 rpm, at the edge. However, at a spot closer to the center will be spinning faster. Now, at normal speeds this isn't that big of a deal, but what about a centrafuge spinning at say 70% the speed of light. Wouldn't that mean there are actual spots on the arm of the centrifuge spinning faster then light speed? Of course, that is rather impossible.
