Damn, I'm not getting notified about these talk-page messages. Do you know how I switch email notifications on for such responses? Yes, I've done a lot of work there, but am tightly constrained in how much I can reveal regarding the sources of any so-called "original research" material. Suffice it to say that I was privileged to work in the Dept of Physics at Auckland University (NZ), aged 19, as a research assistant (40+ years ago), where I made friends with a few young doctoral students, one of whom was researching gravitational waves. I then studied physics at the University of Canterbury, under Prof. Roy Kerr, the rotating black hole theorist. I've kept in touch with a few of those guys over the years, and they've introduced me to certain other "big names" in physics. I bailed out of the academy before gaining a doctorate, preferring a broad interdisciplinary education, and disgusted by the stress, pressure, politics, and the close-minded arrogance of certain professional academics. I had a fun life instead, and followed my curiosity about gravitation, astrophysics and cosmology in a totally relaxed way. Over the past decade or so, I've been privy to hearing about some very exciting developments in theoretical physics, particularly with regards to the unification problem. I can't say too much, because *cough* Nobel *cough*. If, just saying, somebody (hypothetically) had actually nailed the spin-2 boson, but hadn't yet published anything until it's mathematically robust, peer-reviewed, etc, then it's (hypothetically) highly likely that the solution would involve a mathematical toolkit comprising complex dimensional analysis, multi-dimensional special & general relativity, loop quantum gravity, E8 Theory, etc. Just wildly speculating here, but it's the 100th anniversary of Einstein's publication of GR — could be a very big year for physics.
