Light propagates always at c in vacuum. A dielectric is atoms separated by vacuum. The velocity of the phase of a wave is the resultant of the radiation generated by the acceleration of the outermost electrons of the atom and thus the reradiation process creates a front that displaces the energy...

Thanks for your answer, Chronos. I wish I was an inquiring mind, really! Rather I am just an outsider in this world and became interested since I have read a recenssion on Smolin´s book and since my son bought his first string theory book (Swiebach), intending to follow that "string". I would be...

I am looking from some information regarding String Theory. Is this the correct place to look in the physics forum? Thanks!

Hi! And Thanks! The Section of L&L I am referring to is the Problem Part of Section 90 of The Classical Theory of Fields L&L. They derive the EM field equations in 3D form, using "gamma" determinant and "g" vector. They state that equations 4, 5 and 6 are the 3D versions and they notice the...

Hi! From what I have read in this thread, it seems to me that there is a difference between Kopeikin and Fomalont claims analysed critically by C. Will and you, and Felber´s, Mayer´s and the others you cite. As others contributors on this thread agree with you, Kopeikin is recognized as a...

Hi! Following Landau&Lifschitz (L&L) (I´m not a researcher in GTR) it is possible to arrive to a 3D version of Maxwell equations in a GTR-correct form. These equations resembling the ones in a dispersive electric and magnetic material, suggest, at first glance, that there should be a dispersion...
