WRT new gravity theories: there has been some mention here in the past by Terry and Horace of one of the most eccentric and brilliant minds of the past century- Burkhard Heim.
He is called the "German Hawking" (Stephen Hawking) but is not as well known - yet- IMHO he is more perceptive and certainly more creative; sometimes being creative is counter-productive in advancing theories, but if his work eventually proves out, he will be elevated to the level of Dirac and Einstein. Of course, one must overlook a few 'quirks', but that has been true of many great thinkers. http://news.bbc.co.uk/1/hi/health/2988647.stm Anyway, at the age of 19 Heim was recruited by the Nazis to the air force, which led to his working in a explosives laboratory. An accident there left him without hands, deaf and blind. Yet he persevered; and without the need to be "reinterpreted" by other PhDs, as has Hawking for instance. He had been a most precocious child. In school, he taught himself thousands of Chinese characters, with which to write secret messages. He could learn a new language in a matter of days. Anyway - here is the Wiki entry on Heim theory: http://en.wikipedia.org/wiki/Heim_theory It looks to me like Volfson may have borrowed extensively from this, and that may be why his theory has some validity.
