Sorry, No Light Speed Will Be Achieved In The Experiment

When your rod starts to move with speed close to c, mass of its end starts to grow and thus you will never be able to achieve 100 rev/sec.

When you wave a flaslight across the Universe, then of course "the end of your light beam" crosses the Universe with superluminal (much higher than c) speed. But "the end of the light beam" it is not a materialistic object, upon close look it consists of many DIFFERENT photons which were radiated in sequence and in different direction. One went east, and a second later another went west. 10 billion years later one will be detected in east corner of Universe, and exactly one second later the other one - in west corner. It indeed looks like a water spiraling out of loose garden hose: while each drop of water moves straight (or over parabola in gravity of Earth), the shape of water stream is a spiral. Do you have problem with that?
