the seventh major philosophical proposition in history: Einstein's Light (Einstein's Beam)~ Einstein's famous special theory of relativity is a thought experiment that was set up at the age of 16. In his autobiography, Einstein recalled that he had dreamed of pursuing a light in the universe. He reasoned that if he was able to move around the light at the speed of light, he should be able to see the light as "an electromagnetic field that is constantly oscillating but stagnant in space." ~ for Einstein, this thought experiment proved that for this virtual observer, all the laws of physics should be observed by a observer who is relative to the Earth's stillness. ~ Below is the Interpretation section ... in fact, no one knows exactly what this means. Scientists have been arguing about how a simple thought experiment could help Einstein accomplish such a huge leap in special relativity. At the time, the idea in the experiment ran counter to the "ether" theory that had now been abandoned. But it took him many years to prove he was right.
