Conservation of matter and energy in a universal sense is NOT a part of the 4-D cosmological model! I still contend the problem with those calculations is conceptual disparity. I have not seen the work you describe, but it sounds interesting and I will have a look-see! Regards, Sam Cox

P.S. Just as chalk is observed by us to fall in a straight line, we observe the rest of the universe, from our 4-D perspective in much the same way. We have to look for those subtle clues- but they are there...as of course you know!
