JimJast: The paper by Jastrzebski that you cited is way beyond my level of comprehension. Although I'm a physicist and been through the derivation of the Einstein field equations of general relativity, my familiarity with general relativity remains that of an amateur. I'm certainly not about to suggest that the Jastrzebski paper is fraudulent, but I cannot dismiss that possibility. There is a book entitled "Fads and Fallacies in the Name of Science" that cites many exmples of fraudulent attacks on general relativity among other subjects. I once encountered an example myself of what appeared to me to be such a fraud. It was a manuscript that I was asked to evaluate by the Director of Research of the place where I was working at the time. It purported to prove that the steady-state theory was correct and to disprove the Big Bang theory. It contained. among other things, a reference to the Lee and Yang paper on parity con-conservation for no apparent reason. He worked for the same company I worked for and, after I reported my findings to the Director of Researched, he was invited to present his theory to the theoretical physicists in the company and didn't impress them, either. I also sent a copy to George Gamow, a principal participant in creation of the Big Bang theory and with whom I'd had previous contact, and asked him what he thought of it. He responded, as nearly as I recall, "I received a copy of it, too. A lot of arm waving with no significant substance. So down into the waste basket with it." The last sentence is a direct quote that I especially remember, a reflection of his less than perfect mastery of American idiom.
