Some of you may be familiar with Dingle, an "opponent" of SRT. I can condense his argument (the only one I know about anyway) to a sentence or two. Solve the Lorentz Transform for delta-t-prime, then divide through by delta-t. delta-t-prime/delta-t = gamma - gamma*v*delta-x/delta-t [Dingle] "We therefore get different values for the ratio according to the (location of) events we choose... We can, by a suitable choice of events, make (delta-t-prime) greater or less than (delta-t), by any amount we like. But ... the relative rates of the clocks must be independent of the events chosen for their determination." SRT sure explains a lot of stuff, but I can't figure out what may be wrong with his argument. Any help appreciated.
