The ugly ******* won't answer MY questions. See if you can answer, rot: Catch 22: http://www.fourmilab.ch/etexts/einst...ures/img22.gif http://www.fourmilab.ch/etexts/einst...ures/img76.gif Heller wrote: "There was only one catch and that was Catch 22, which specified that a concern for one's safety in the face of dangers that were real and immediate was the process of a rational mind. "Orr (a character in the novel) was crazy and could be grounded. All he had to do was ask, and as soon as he did, he would no longer be crazy and would have to fly more missions. "Orr would be crazy to fly more missions and sane if he didn't, but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to." In Einstein's case if you use c+v you can derive c = (c+v)/(1+v/c) from the cuckoo malformations he blamed on Lorentz. That says you can't use c+v. Troll kooks such as Uncle Schwartzschit, Blind Poe, Moron McCullough, Humpty Roberts, Phuckwit Duck Draper, Sad and Lonely sal Lawrence, Tusseladd ASSistant professor Andersen, Shrine to Spirits Nieminen, Ghost ewill, Goosey Gisse, ****** Olson, Minor Crank Tom & Jeery, Fecal Jekyll, Bilewacky, Dork Van de merde et. al. fail to realise is the existence of isomorphism http://en.wikipedia.org/wiki/Isomorphism between Sagnac's real experiment and Einstein's hallucination experiment, shown he http://www.androcles01.pwp.blueyonde...oSpeedRack.gif Einstein sends light along the rack and back again, the rack moving at velocity v in his pipe dream. Sagnac sends the light around the gear wheel for real. If you analyse one you should get the same result as the other, but you cannot use SR to derive SR, that is petitio principii, circularity. http://en.wikipedia.org/wiki/Begging_the_question c+v is essential to the derivation of the cuckoo malformations, the part where Einstein screws up is: 'we establish by definition that the "time" required by light to travel from A to B equals the "time" it requires to travel from B to A' because I SAY SO. -- Rabbi Albert Einstein What he is claiming is that his "definition" is true for all frames of reference. The absurdity that the velocity of light is the same in all frames of reference is a consequence of that claim. http://www.androcles01.pwp.blueyonde...rt/tAB=tBA.gif Here are some mathematical proofs: http://en.wikipedia.org/wiki/Mathematical_proof Not included are Proof by "because I say so", Proof by "everybody knows", Proof by "it is written", the three most popular forms used in sci.physics.relativity. You'll often see this pathetic mob muttering "Lorentz Transformations" but they haven't a clue how they are derived and faithfully follow their indoctrination like lemmings. Catch 22: http://www.fourmilab.ch/etexts/einst...ures/img22.gif http://www.fourmilab.ch/etexts/einst...ures/img76.gif Prediction: The troll kooks will ignore it, they are too stooopid to understand a proof. RULES OF REASONING IN PHILOSOPHY. RULE I. We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances. To this purpose the philosophers say that Nature does nothing in vain, and more is in vain when less will serve; for Nature is pleased with simplicity, and affects not the pomp of superfluous causes. -- Sir Isaac Newton ["tj Frazir"] If you pushed a rod 1 light year long the other end wont move for 1 year. ["CWatters"] Suppose you apply a small displacement by compressing one end with a hammer. Does the shock wave still travel at the speed of light? [Androcles] Clearly the extrapolation (increasing rigidity yields increasing speed of sound) indicates either there is limit to rigidity or there is a limit to the speed of sound in a material body. Given that a material body is made of atoms then atoms are not rigid... but we do not expect them to be anyway, the model of an atom is that of a nucleus surrounded by a mantle of empty space and a shell (or shells) of electrons. By compressing the atom we force the electrons into the nucleus, the charges cancel and we are left with a nucleus of incompressible neutrons where the limit to rigidity has been reached; for either the neutron is totally rigid or the speed of sound in neutrons exceeds the speed of light. "Thus with the help of certain imaginary physical experiments we have settled what is to be understood by"[1] neutron stars and proven black holes do not exist, the extrapolation has gone too far.

How is Schitz's "Gravity from the ground up?" going? Have you finished reading it? If so how did you like it? Best wishes Hi Pete The limit of my GR knowledge is founded in the metric equations which I learned to use when I worked through Edwin's book. I havn't finished 'Gravity from the ground up' because I've temporarily lost the drive to further my knowledge of gravitational physics. Hopefully I'll get it back. This thread begins with the pronouncement to 'forget about curved spacetime' because the path of light, in a gravitational field, is a function of 'light has mass'. Apparently the originator of the thread has a problem understanding the purpose of scientific theoretical models. Which is to accurately make predictios wrt natural phenomena that can be empirically confirmed. What's important is accuracy within a domain of applicability and usefulness for doing scientific analysis. I think that jives with what Thorne was saying when he sometimes prefers to use the teleparalel equivalent to GR for analyzing gravitational wave phenomena. That's how I see it.
