Was Einstein Wrong? In Chapter 9, The Relativity of Simultaneity, of Einstein’s book Relativity (http://www.marxists.org/reference/archive/einstein/works/1910s/relative/index.htm), Einstein said: “Hence the observer will see the beam of light emitted from B earlier than he will see that emitted from A. Observers who take the railway train as their reference-body must therefore come to the conclusion that the lightning flash B took place earlier than the lightning flash A.” Were these words wrong? We understand, in Einstein’s thought experiment, besides observers he also had a mid point on the long train like this: A__________M’__________B. Taking such a long train into our consideration, his words must mean: the beam of light emitted from B will reach the mid point M’ sooner than the beam of light emitted from A. I think such a meaning is wrong; Einstein was wrong in saying it because light will cover equal distances with equal time regardless how the train is moving. Taking equal time to cover equal distance means light from B and A will reach mid point M’ simultaneously, contrary to Einstein’s words. Furthermore, when he said “Observers who take the railway train as their reference-body……” my understanding of those words was: there is a mathematical way to support their conclusion. Since those observers and Einstein did not use mathematics to support their “…conclusion that the lightning flash B took place earlier than the lightning flash A”, I wish some one here could. Please oblige. I am a hobby reader. I have no formal training in physics.
