I've been thinking about this for a while now. I suppose I call it the Ferris Wheel. It has to do with relativity / the speed of light. A Ferris Wheel spins...slower at it's center, and faster at it's edge. If (use your imagination) you could build a Ferris Wheel big enough, and get the central rotation up to close to the speed of light, wouldn't the outer edge of the Ferris Wheel be moving faster than the speed of light? I know that realistically it would fall apart before this ever happened...but theoretically? Also, same concept, different question. All motion is relative, yes...so when I spin in a circle, the entire universe revolves around me. Galaxies at the edge of the universe will be stressed to complete an entire rotation around me, covering a very large distance in a very small amount of time, so they would need to be traveling faster than light. I'm pretty sure this is flawed...can anyone tell me why?
