The "light clock" sequence is probably the most sensible and concise explanation of time dilation I've ever seen.
Remember that the differences in time passage are too tiny to ever notice until you start dealing with relative velocities that approach a significant percentage of the speed of light. The Relative velocities observed by humans in just about all situations, except maybe inside a partical accelerator are too slow to amke a noticable difference.
the light will hit your eyes at EXACTLY the same time (because the keys are at the same distance to you), which is correct. Now this is where it gets odd, but its obvious. Now imagine you are on the left side of the keypad looking at it, so QWERTY isnt horizontal, but diagonal, with Q at the bottom and Y at the top, if you now hit the T and Y keys will both radiuses of light hit your eyes at the same time? The answer is no, you will see T first then Y, because T is closer to you, NEXT>
(camera), arent only, watching the clock go horizontally, theyre also watching the beam move horizontally with it, now if we were on the clock moving with it, the clock wouldnt be moving at all, only the beam would (up and down) at the normal seed. IMAGINE THIS: You are facing the keyboard so QWERTY is horizontal in your P.O.V, and you click the T and Y Keys on the key pad simultaneously, now imagine two slowly expanding radius' of Light coming from the keys, from your P.O.V, NEXT>
OH!!!!!!! Haha, ive just realised what the whole clock thing means. It literally is RELATIVE. They shouldve took the light trails off the beam, and used the view point of the moving clock as a way of making RELATIVE, clearer.
From our "stationary" standpoint it seems as though the light beam (which is traveling exactly the speed of light) in the MOVING clock takes longer (than it would if it was stationary with us) to get from top to bottom, it only seems this way because the observers NEXT COM>
the speed of a spacecraft will be different relative to earth and than the moon. so, the time passed will different on earth than on moon. i don't think (the theory of relativity makes sense.)
''it travels diagonally and there is larger distance to travel). This only proves that the clock is not accurate.'' in wich clok beam doenst travel diagonaly, is acurate? Clock in your living romm 1)rotates around earth 2) it travels around sun 3)it travels around galaxy . .an so on, there are many moving frames.'' it should again give different time.''well science sez it doesnt, altough i couldnt prove it wit simple using geometry(compering clocks H and V positon), maybe someone could give it.
Sorry i was meant to say: " Im really trying to understand why you would get older slower, the more momentum you have, in relation to someone elses momentum"
Why O Why is this clock using light as a means of measuring time?! of course its gonna "run" "slower" the light has to go diagonally!! Im really trying to understand why you would get older the more momentum you have, by brain is overloading!! HELP!!! :)
