To start off, I am in my second year of high school physics so please be discriptive if you make reference to any sort of theory. We have begun to study relativity, and two things occurred to me. First, assuming that nothing can go faster than the speed of light, could two spaceships traveling in opposite directions go .99c? It would seem to me that since the frame of reference is moving at a speed of .99c, the spaceship moving opposite it would be traveling at a speed of 1.98c. Is this possible? Second, it is basic knowledge that the inside of a wheel will spin slower than the outside of a wheel. What happens if the inside of the wheel is spinning at the speed of light? The outside of the wheel must then be moving at a speed that is greater than c or the wheel is tearing itself to pieces. Any ideas on what happens in either scenario would be insightful.
