Motion curvature of matter is determined by its speed through space-
time curvature of which is the null geodesic. There are two kinds of curvature one for matter varying with speed and one for light. Mitch Raemsch Twice Nobel Laureate 2008 |

There are two kinds of curvature one for matter varying with speed and one for light. Mitch Raemsch Twice Nobel Laureate 2008 Space has curvature not matter. Space curvature is determined by the mass causing the curvature. In the case of non-zero rest mass particles, the energy is determined by the rest mass and the velocity. In the case of zero rest mass particles, the energy is not determined by the velocity as it is, in all cases in vacuum, the speed of light (c). In that case the frequency of the light is used to determine the energy of its particles. This is a case where quantum and relativity are related as the frequency of light determines its energy (quantum mech) which is its mass (special relativity) which then determines the curvature of space around it which is gravity (general relativity). Light travels on null geodesics, geodesics which have zero (null) length when calculated using the metric of the space. Non zero rest mass energy, when not disturbed by an external force, travels "ubperturbed" on non-null geodesics. There are not two kinds of curvature but there are two kinds of geodesics (null and non-null). For zero rest mass particles travelling at the speed of light the geodesic is null - for the others it is non-null. Interestingly, for curved spaces, null geodesics can be curved. Hence light does not travel in curved space in a straight line. |

Space has curvature not matter. Space curvature is determined by the mass causing the curvature. How does matter curve space and time exactly? If there is no answer, don't feel so back. Newtonian gravity cannot explain why matter manifests gravity either. GR is just no better than Newtonian gravity law. shrug In the case of non-zero rest mass particles, the energy is determined by the rest mass and the velocity. Then, how do you account for the potential energy? The best way to interpret the potential energy is also a mass change. Faster speed increases the mass; stronger gravity or more curvature in spacetime decreases the mass. The speed must go higher as one travel into stronger gravity or more curvature in spacetime. This is the conservation of energy. However, this concept creates another state of mass to be considered --- the observed mass, the rest mass, and the intrinsic mass. With this concept, things become so much easier. Then, why the physicists do not embrace this? Well, if they do, in a few logical iterations, GR can only be declared nonsense. shrug In the case of zero rest mass particles, the energy is not determined by the velocity as it is, in all cases in vacuum, the speed of light (c). In that case the frequency of the light is used to determine the energy of its particles. This model describing the energy of light is rather too simplistic. Consider the case of gravitational redshift. After all, the energy must be conserved. So, why would the photon decreases its frequency and energy as it propagates out of the gravitational well? You cannot toss away the conservation of energy. This is a case where quantum and relativity are related as the frequency of light determines its energy (quantum mech) which is its mass (special relativity) which then determines the curvature of space around it which is gravity (general relativity). So, are you suggesting a moving body with high speed is able to generate as much gravity as planets? In this case, you are allowing an observer dependent quantity (the speed) to manifest gravity. That means you can play God by traveling with the moving body at desired speed to manifest any gravity of your wish. Light travels on null geodesics, geodesics which have zero (null) length when calculated using the metric of the space. If I am point my flash light towards the north, the path to allow the beam of light to travel from my flash light to the north pole is null geodesic, for it accumulates spacetime of exactly zero. Another path that takes light to travel to south pole first and then to north pole also accumulates a total spacetime of zero --- null geodesics. So, why does the photon favor one null-geodesic path than the others? Non zero rest mass energy, when not disturbed by an external force, travels "ubperturbed" on non-null geodesics. There are not two kinds of curvature but there are two kinds of geodesics (null and non-null). For zero rest mass particles travelling at the speed of light the geodesic is null - for the others it is non-null. Interestingly, for curved spaces, null geodesics can be curved. Hence light does not travel in curved space in a straight line. This is a great conjecture. The experiments that are supposed to prove the conjecture so are ** Eddington's 1919 expeditions to observer that solar eclipse ** Shapiro's bouncing of radar off Venus Eddington did not have the accuracy in his experimental setup to measure the deflected angle. So, the 1919 event cannot be taken as a scientific proof of your conjecture. Shapiro's experiment requires one to compare the experimental result with a control reference. Without an interferometer, the claim is very questionable. So, your conjecture is still not yet proven valid. shrug |

In this case, you are allowing an observer dependent quantity (the speed) to manifest gravity.

What the *components* of the tensors are that appear in the field equations, those are frame-dependent. Oh, I forgot, you don't know the difference between a tensor and its components.

PD- Hide quoted text - - Show quoted text - -------------------- people like PD are walking disasters for the advance of science! not only that they are list little parrot mathematicians they have not a basic physics touch!! and the worst thing those little pompous crooks PRETENT TO SPEAK IN BEHALF OF SCINCE !! who ar eyou little crook to speak in behalf of science !! who are you in spaeaking in behalf of pioneering science !! what have you little parrot innovated in physics who nominated you to teach what you don't know ie who nominated you to teach your ignorance ??!! space is nothing and has no properties except hosting science anyone out time who has a basic logic realizes that gravitation is property of MASS got it idiot ?? if there is no mass there is no gravitation toeven a little chield who was not stuffed with biased prejudices will understand it . at the beginning of the 20th century it was nice from Einstein to make a trial idea but 100 years later ?? i am sire he himself would realise it was a false assumption now to your crooks claim that GR explains Nice;y' gravity 1 it does not explain the connection between gravity and other attraction force s 2 you say sort of : 'if we dont know something to scratch 'physics does not get excited about it ' may be idiots crooks like you do not get excited so dont you crook TURN YOUR MISUNDERSTANDING TO A LEGITIAMTE AND EVEN ADVANTAGOUS SITUATION!! if you dont know and understand tan say it loud and clear that that is A DISADVANTAGE A A LOKOON in the existing situation and if idiot like you are happy with the existing situation DONT ISPIRE THAT IDIOTIC SMUGG MOOD ON OTHER PEOPLE with the crooks pose of 'every thing is controlled by me and other GREAT PHYSICISTS !! because you are not a great physicist you are a very little one (may be a great lawyer not a great physicist) may be at most a true believer good parrot and the op is right !! gravitation is dome by some property of mass!! NO MASS NO REAL PHYSICS !! 3 dont you speak about potential energy and energy at all because you are an pompous crook ignorant about it !! 4 one of the great lies is that GR calculated gravity proprly just by the bet theiry of GR all those calculations that look so nice were fiddleling experimental data to look as done by bet theory the fact the Newtons theory cannot calculate gravity is the same reason that GR cant to it without fiddlings IT IS BECAUSE GRAVITAION IS A SPECIAL CASE NOT UNDERSTOOD PROPERLY UNTILL THIS VERY DAY !! and the sooner people understnad it the better !!!
