What would happen if a disk one light second in circumference were to spin at 60 RPM?
Submitted by: Administrator60 revolutions per minute is one revolution per second.
1 light second is the distance light travels in one second.
What this means is that points on this hypothetical disk's perimeter would need to travel at the speed of light to satisfy your conditions. This cannot happen for anything that has mass.
Bottom line: a disk this size could not spin at this speed.
