This is a non-local example. I suppose you understand the ramifications of your statements on the nature of physical reality. Somehow I don't think my statements are going to affect nature or how she operates the universe. (:-)) If you do understand what non-local non-conservation of energy implies, why do you still deal with GR and not going back to your drawing board for a better theory? Because GR _IS_ the best theory we have right now for such phenomena. By a considerable margin. Non-local non-conservation of energy is not a problem, and GR itself agrees with all experiments within its domain of applicability[#]. Experiment is the touchstone for physics, not the nebulous ideas you seem to think imply there is a "better theory" out there.... [#] But there are some tantalizing intimations of new phenomena and/or possible violations of GR: dark matter and energy, and the anomalous accelerations of Pioneer and other spacecraft. Just for the purpose or being a little more explicit without crashing the ongoing party, do you believe Dr. Roberts there is some process that non-locally pumps or drains energy so that the world is maintained? Huh? There is no "pump or drain" involved in the non-local non-conservation of energy, it's just that in general there is no self-consistent definition of "energy" over a finite region, and if there is no well-defined notion of "energy", how could it possibly be "conserved"? Take a non-local region. Divide it into N local regions. In each local region energy is conserved. No. In GR energy is conserved only approximately in any finite region; it is exactly conserved only in the limit as the 4-volume of the region goes to zero. That is, conservation of energy is expressed as a differential equation, and in general it is not integrable. But that may not be the case in the union of these non-local regions according to your heterology. I have no "heterology", I merely point out that you cannot generalize this property that holds only in the limit as 4-volume = 0 to a finite region. shrug I do not see anything that happens according to GR in between these local regions that can result in a non-local non-conservation of energy. Clearly you do not understand the issues involved. There are thorns when attempting to union an infinite number of infinitesimal regions into a finite-sized region. This is called "integration" and for the integrals we are concerned with, the general integrability condition is that the Riemann curvature tensor be zero (i.e. the manifold be flat throughout the region of interest). That is sufficient but not necessary, and there are some special cases for which Riemann is nonzero but a meaningful global definition of energy can be made. Tom Roberts All of this debate is due to the fact that relativity has no strong model. It's all done with Schwarzschild and it contains errors. I can see that nearly everyone believes gravity reduces the frequency of light. And that clocks run slow in gravity. And that, generally speaking the velocity of light is constant. Er, except for Shapiro. Lots of debate about how energy can't be conserved. Dual Space theory has it right: a clock in gravity will run slower and its emitted frequency will be lower than out of gravity. But, energy E = hf never changes after that. Likewise the speed of light is reduced at the origin in gravity. Therefore right at the source (with the clock in gravity) the clock is X% low, its emitted frequency is X% low, and the WL is normal = 1. But on rising out of the gravity field, the energy hf remains the same, but c increases by X% so the WL stretches by X%. That's the red shift-increase in wavelength. The frequency remains as manufactured and with its original energy never more or less. But in relativity, the Pound and Rebka ("Possible Weight of Photons") experiment talks as if the frequency is reduced on the way out of a gravity well due to energy loss % = gh/c^2. So if it loses X% in frequency on the way out, and is now measured for frequency by a clock outside that is thereby running X% faster, the difference in frequency will be 2X% double the ideal value. The cause for the Shapiro effect should be derivable from the Schwarzschild metric but I haven't seen it done. In Dual Space, c reduces X% with gravity (in place of "time dilation") and also the underlying space cells dilate by X%, because gravity is a sign of a weakened underlying Espace. With DS you can get all of relativity in a Cartesian model, besides which DS can explain the Pioneer anomaly. I am finishing up a paper on it for the arxiv's. John Polasek http://www.dualspace.net |
