So lets take inventory of all the scenarios that are being piled up on me. Every single person is convinced I will not address them because I somehow can't and want to live in my own unchallenged self-consistent delusion. Again, I'm not anyone's employee here and you'll all just have to be patient. I'll answer all questions in whatever order I feel like. So don't go assuming I'm avoiding any of your tasks just because I haven't gotten around to them yet. Right now I've been concentrating on whether my equation for length contraction has been wrong for years. I've found the source in one of Greene's videos where he says x=x'/Y at 10:36 and in another where x=Yx' just like t=Yt'. For me, (t',x') are the moving rotated coordinates while (t,x) are the stationary cartesian coordinates. v=x/t , v'= x'/t' and if x'=x/Y and t'=t/Y then x'/t' =v' = v. There are no concepts like time contraction (t'= Yt") or length dilation (x=Yx') similar to time dilation (t=Yt') in SR taken from different perspectives as I showed in #116. Dilation and contraction mean the same thing even though two different words are used. Greene was inconsistent with his labels and since I never had to use length contraction I didn't notice I was using the wrong formula x'=Yx. Now why would I hate to be challenged if it points me to mistakes like these. Maybe SR uses a convention that both coordinate systems use x and t axes within their frame but the moving one gets converted to x' and t' axes when viewed from an outside perspective. If this is true then his formula x'=Yx would make sense but I just assigned the moving frame automatically with x' and t' axes. Maybe that's why no one has been understanding my x' and t' notation.
