About time dilation. We remember the descriptive diagram which includes, for example, the train which moves at a speed "v". The two mirrors installed in the train between which a beam of light circulates constantly. There is also an external observer who, according to the descriptive diagram, observes what is happening. According to Einstein this observer who is outside the train, this observer being stationary, observes that the time it takes the light to travel the distance between the two mirrors dilates! In my opinion we cannot observe a dilation of time, moreover we do not yet know what is the definition or the concept of time is!!! In my opinion the outside observer can notice that the speed of light is a constant which is, c,!! But according to me the light circulating between the two mirrors "sees" its time dilates because of the speed of the train!! thus the speed of light circulating between the two mirrors is no longer, c, but less than, c!!! And in my opinion, light has an intrinsic property which is the dilation and each dilation corresponds to a reduction in its speed so that it becomes less than, c! and in my opinion this must be the principle of atomic clocks which delay when they are moving at one speed, v!! In other words it is not gravity that slows down an atomic clock in mouvement at a speed, v !!
What people thing about this problem?
