timo Posted September 22, 2006 Share Posted September 22, 2006 The result you get is exactly the same. I already wrote "that´s the rule to raise and lower indices" but I failed to note how it looks if you raise them, sry. Raising an index: [math] \partial^{\mu} = g^{\mu \nu} \partial_{\nu} [/math] EDIT2: But I don´t understand where you get powers of diagonal elements. The term is linear in g.

Quantoman Posted October 13, 2006 Author Share Posted October 13, 2006 thanks for your replies... so from what a gather light does curve. btw- the light i was refering to was suppose to be a laser shot on earth, dont know if that makes a difference.

JHAQ Posted October 15, 2006 Share Posted October 15, 2006 Apart from space-time relatavistic effects , it also curves when passing through a prism -- or does it ? Link to comment Share on other sites More sharing options...
insane_alien Posted October 15, 2006 Share Posted October 15, 2006 no it doesn't curve in a prism, it refracts. it can be set up to look like a curve if there is a constant gradient in the refractive index of the material. Link to comment Share on other sites More sharing options...
SyedAmeen Posted January 24, 2007 Share Posted January 24, 2007 In case the question was meant the other way round: Light not also follows the curvature of space, it also contributes to spacetime-curvature. jan.23.2007 This talk is out dated.This was how light was seen,and relativity was promoted. But Einstein and others in his era did not know the REAL NATURE and ORIGIN of PHOTON. Now my research and other supporting works showing that a PHOTON is not one particle but an ENTANGLE QUANTUM STATE of two particle system.There are faster than velocity of light particles or entities,called IGNORONS.They do not interact with matter but show specific affinity to liberated charge particles,like e-.When ignorons encounter freed charge particle,entangled quantum States is born.This is our so called PHOTON, The mechanism involves: a forged forced fermion to boson transformation. So light is now an entirely different thing than what was seen by Uncle Einstein et.al. It is a wave field of ignoron into which charge particle ,like e- ,lodges. see: http://mywebpage.netscape.com/drsyedameen1/index.html links listed in viewing my Blog at: http://www.myspace.com/syedameen Link to comment Share on other sites More sharing options...
Klaynos Posted January 24, 2007 Share Posted January 24, 2007 SyedAmeen, Your ideas are not accepted science, so calling the accepted science wrong, without any sound evidence (whether this is RIGOROUSE theoretical or experimenta, which I don't see on your sitel) is not a good idea, and for your own sake, and so that people don't just dislike you before actually reading what you've got to say because it might actually have some worth (I've not read it fully) don't post in other peoples threads. It's probably best if this is kept to psuedoscience. I'm sure the mods will glare at me for this nice bit of back seat moderating (I love you guys to) but I'm bored...
