kindly be descriptive
Unfortunately he doesn't lay them out as a list. But basically it's homogeneity and isotropy of spacetime, relativity of motion, causality, and observer-dependence of time. Here is my own treatment: http://lightandmatter.com/area1book6.html There is an appendix in the back of the book that lists other treatments in this style.bcrowell - interesting, but I wonder --and it seems pretty important in this discussion-- what were Rindler's axioms?
The snarky answer is "Because." That is the answer given in Einstein's 1905 paper. He postulated that the speed of light is the same to all observers. Remember back to when you were a kid. Some kids pester their parents by repeatedly asking "why?" The parents inevitably get flustered at some point and answer "Because I said so." Think of a postulate as being a scientist's or mathematician's way of saying "Because I said so."But why is the speed of light the constant why not any other speed?
Occam's razor.And why is this perception rejected?Looking at relativity from the perspective of length contraction and time dilation being the cause, and a constant speed of light the effect, is a long-since rejected notion.
That was a thought that also occured to scientists of the time. They tried many variations at different altitudes, with different amounts of matter nearby, etc. Nothing made any difference.What about possible ether dragging proportionally to gravitational force (or maybe proportionally to gravitation energy density) + Lorentz contraction together?
In this way famous MMX becomes unable to measure anything.
i really think that the fundamental answer to the question is an extrapolation that Einstein made from perceived reality (observation) to reality.hi akshay.wizard! welcome to pf!
the structure (the metric) of space-time has a preferred speed
anything with that speed in one frame will have the same speed in all frames
light happens to travel at that speed
