So we have a seeming contradiction. How can the speed of light be constant in any frame of reference? My guess, not being a master mathematician (I can no longer even remember how to derive the first fundamental theorem of calculus) is something like this. We have a Universe containing Matter composed of whatever and light. The ONLY thing in this Universe that is NOT “plastic” is light. Everything else can be distorted and distorted in ways that are not the same for different observers. The only way for this to be true is that while we feel the Universe is constrained to conservation in the three dimensions our senses are familiar with is NOT true. I suppose this is the reality that REAL mathematicians are struggling with. I remember asking my Calculus teacher that if we can add dimensions by integration and we can mathematically deal with a seeming infinite number of dimensions why do we assume there are only three? He said, “46”. (Just joking, he said the math is theoretical and not real. We use math as a tool to understand reality and reality is not bound by math.).
Consider. We have point “X”. If we move point “X” over a period of time to a new location we have now two point and an interval of time. So now we are dealing with velocity. dx/dt. We can further go to acceleration by dv/dt. Integrating again we get “The Jerk” (not 0bama or Hillary) which is da/dt. These are all different dimensions of motion. So right there, mathematically, we have four dimensions of motion. Position, velocity, acceleration, and The Jerk. We can do the same thing with dimensions of space but intellectually it is more difficult for us to conceive of more than three spatial dimensions.
Sorry, somewhere along the thread I missed your #60.
Gotta tell ya though, most of it was waaaayyyy over my head
