Lately I have been studieng up on my Theoretical Physics. I feel I have a pretty good understanding of SR, but there are still some holes that nobody, not even my science teacher can help me out with (Im only in 8th grade, so Its not a big surprise that my teacher has no idea... no offense teachers out there). Oddly, SR is the only theory that has given me trouble... GR, QM, ST etc make perfect sense to me... Its pretty basic knowlage that the speed of light is the same no matter who is measuring it, no matter how fast they are going. Any book I have read on the subject of Relativity (mostly non mathamatical books... e= what now?) has flat out avoided answering WHY this happens. A quick google search gives me the common answer of that, of course, time slows down, thereby magically making the speed of light the same no matter who is measuring it. This makes NO sense to me. Sure all time process are slowed down, but his movement through space isnt. If his movment through space was slowed down, it would have to be down to a complete stand still, no matter what speed he was going. Even if he didnt have to be slowed completely down, him moving through space due to time dilation would just cancel out the time dilation that caused it, because it was originally caused by him moving through space. But that same resuming of normal time would cause him to resume going through space at his normal speed! Which would slow down time again! Gah! So whats going on? Please god keep it un mathimatical. Spare me the headache. #2 Same line of thinking as before, but now lets just accept that the speed of light is the same for everyone, who cares why. So lets say we have a single photon, Nick, who is at a complete standstill, shoots it out into empty space at the speed of light. Now Jimmy run beside the photons at the speed of light. Sinse we know that they both should see it shooting away from themselves at the speed of light, no more, no less, wouldnt that mean that when they get back together and compare where they saw the photon at any given time, wouldnt they report two completely seperate places for the photon? From Nicks standpoint it would look like: nick ---------------------------@ jimmy -> Because hes running at speed of light But from Jimmys standpoint it would look like: Nick--------------------------------------------------------@ Jimmy -> because the photon is running away from him at the speed of light. So where is the photon? At the time of when special relativity was published, quantum mechanics wasnt around to say that a particle could be in two places at once (so please dont use that answer). Thanks alot.
