Dr. Corda,
I also was pleased to see someone celebrate the centennial of General Relativity and had read your abstract immediately. I was not surprised to recognize that I'm not equipped to venture in without a guide and browsing for information confirmed that. The salient feature appears to be the disjunct between SR and GR, and the lack of a unified field resolution that would make GR definitive of a discrete non-zero point particle applicable to QM.
Though a novice to GR, and only dragged kicking and screaming by the persistence of Thomas Ray to an understanding of it being a selection of interconnecting maths that operate more like a computational device than 'a theory' which is its own co-ordinate system, I was finally disabused of what is probably a common niave assumption that GR is an extension of SR. And while SR is perhaps the most experimentally confirmed theory to date, the time metric remains under constant challenge.
At issue is the observer experience commonly illustrated by Einstein's epiphany of riding a beam of light and time 'stops'. It is mathematically complete but is based on the metric that the speed of time is one second per second at relative rest and ,Lorentz fashion, is zero second per second at light velocity. If we look at that in reverse, gravitation is the negative acceleration linearly from 1 sec/sec at c, down to relative rest at 0 sec/sec, and perhaps analogous to Unruh's 'uneven flow of time'.
If we look at SR from a paradigm that time in a stationary frame appears to stop in the experience of an observer in the light velocity frame, because light velocity is equivalent to the limit rate to which time can extend, then both observers can proceed through time at their respective gravitational rate. Energy is mass existing at light velocity but doesn't have to extend spatially to infinity. It remains mathematically complete, and suggests that 0 sec/sec @c | | 1 sec/sec @ 0 , is a 5th dimension.
I think it was Fitzgerald whom remarked that the finite speed of light is 'astonishingly slow'. Coming down from instantaneous at infinity (?), yeah, he's right. It's like a stone. Thank-you for daring to push the limits in such a public forum, and giving feast for thought. Sincerely, jrc
