Something that has been bothering me for a while is this question. As seen from this Minkowski diagram,http://imgur.com/GkBN2HQ , the angle between x and x' is equally big as the angle between ct and ct'. I really can't seem to figure out why this is, although I think it has to do with the second postulate of special relativity, which is "The speed of light in free space has the same value c in all inertial frames of reference". Is there anyone here that might be able to help me? Kind regards (English is not my native language. Sorry)
