It's far from widely known fact that before Einstein's theory, there was Heaviside's simpler approach to make gravitation Lorentz invariant - by using a second set of Maxwell's equations - with e.g. density of mass instead of density of charge http://en.wikipedia.org/wiki/Gravitomagnetism Actually it is widely known by physicists, and is even more widely known to be wrong. Gravitational dipole radiation does not exist. This much less philosophically controversial theory (matter is not prisoned in infinitely thin submanfold of something with which it doesn't interact ... allowing for wormhole-like solutions...) agrees well with most of observations (?), Yeah, "(?)" because it isn't true. even with Gravity Probe B. Some papers says that even in better way: http://www.mrelativity.net/Papers/14/tdm5.pdf open pdf "Did Einstein cheat ?" close pdf There can be also found strong arguments, that electromagnetic field also causes time dilation - for example while measuring muon lifetime in muonic atoms: http://www.springerlink.com/content/wtr11w113r22g346/ Electromagnetic fields do not cause time dilation. Idiot. My interest on this subject started while I was working on some model in which the main dynamics was local rotations in 4D and it occurred that it leads to natural unification of electromagnetism and gravitomagnetism - spatial rotations gives Maxwell's equations, while small rotations of time axis (kind of central axis of light cone), gives the second set of Maxwell's equation - for gravity (5th section of http://arxiv.org/abs/0910.2724 ). Do some basic research and stop reinventing a wheel that is known very well to not work. What do you think about it? Why 'the only proper approach': intristic curvature is better than gravitomagnetism? |

Sorry if the standard but lazy naming confused you. Within the framework of *classical* theory, the terms "spin-1" and "spin-2" are a standard way to refer to tensorial orders: one versus two. In terms of the *classical* potentials it is the difference between the A^b used in gravitomagnetism and the h_bc used in more general theories of gravitation. Of course, there is close relation between the number of indexes in the potential (one, two...) and the spin of the underlying quantum particle. This is why the terms the terms "spin-1" "spin-2"... are often used in classical theory also. For instance, in the textbook by Wald, he claims that general relativity can be understood as the classical theory of a spin-2 field [#]. Of course, he is not saying that general relativity is a quantum theory, neither he is saying that general relativity deals with the spin of quantum particles. He is merely emphasizing the number of indexes in the metric g_ab. [#] His remark is not at all correct, general relativity only can be understood as the classical theory of a spin-2 field in a Â* Â* geometrodynamics approximation. Do you think that "bert" will be less confused by this? "bert" typically recognizes few more nouns than can be found in the works of Dr. Seuss... David A.

I can be naive sometimes, but I also know that responses to OPs are readed by more than one, But no good can come from following gibberish with fact. It does not provide a path for growth, either for "bert" or posterity. You aren't generating "new thought", simply stating facts the OP cannot follow, appears to be genetically incapable of following / retaining. and wait someone can find something useful in the above or at least be curious enough to open Wald textbook, search where he says that and study why... But someone (other than "bert") would not have been attracted to this topic to see your recommendation. "bert" is an automatic dead end. By responding to him in his less lucid moments, you encourage him, make him feel like his "contributions" are valid. He cannot feel that he needs to study, he cannot hear that his random word generator and his naieve experience is insufficient to be "helping"... David A. Smith |

What do you think about it? Why 'the only proper approach': intristic curvature is better than gravitomagnetism? well, uncertain geometryhttp://sites.google.com/site/jackokringmakes mass units as s/m^2 the recprical of space time power. velocity is current, time is resistance, length is voltage, photon arrives at same time it leaves as v=c. p=v^2.t the EM charge concept then gets units of root m/s. this implies a velocity difference is responsible for the Q^2 in electric force interaction. (c,0)??? The shape of the particle flux causing conservation of charge is as yet unknown to me. The commutivity of the quantum field in this theory is the best feature, allowing easy unification with special relativity. It does however imply relative mass is what we mean by a fixed mass, and the underlaying mass field oscillates. Small differences in phase or frequency account for quantum uncertainty at underlaying mass zero crossings. Cosmic inflation is explained as anti- phase underlying mass going far and in phase coming close. Hubble red?? and does the far off really weigh what is measured?? cheers jacko Yes, Jacko, it is all phase relationships. Milo Wolff did what Wheeler and Feynman couldn't. He gives the mathematical proof that the electron is a scalar, standing wave entity. See: http://www.quantummatter.com/ Also important is the Hubble Limit because as Milo shows us there is NO electron to electron action beyond this Hubble limit. This gives us what we need : a finite yet unbounded universe. See: http://www.rbduncan.com/schrod.htm btw, Nobel laureat Josephson is sniffing around at Milo Wolff's concept now too: All of us are on the right road Jacko and neither Milo nor I nor you have even scratched the surface of what's REALLY down this road!
