    Graduate How Does Time Differ for Observers in Relative Motion?

    Thanks to everyone trying to sort out my confusion. Apologies if I have not used the accepted notation for the times. Firstly about those clocks. I see them as recording clocks. The observer's two clocks are synchronised at the start. Every clock, when it observes an event, prominently...

    Graduate How Does Time Differ for Observers in Relative Motion?

    I thought I had understood the difference in clock rate for different observers, but I am unable to answer the following problem:- An observer O is stationary in an inertial frame of reference, with two stationary clocks which are some arbitrary distance apart. A rocket ship flies through the...

    Undergrad Things that happens simultaneously

    I think I understand the reply from Chestermiller. I depends what you mean by "Simultaneity". If I look up at the night sky and see two flashes of light occurring at exactly the same time, but I then discover that one is from a star 10 light years away, and the other from a star 100 light...

    Undergrad Things that happens simultaneously

    Loss of Simultaneity I too have a problem understanding how Relativity explains Loss of Simultaneity. Consider two points ‘A’ and ‘B’ fixed in space in an Inertial Frame of Reference. There is a flash bulb at each of those points. When a flash bulb fires, a spherical bubble-surface of light...
