    Remark on electric charge Lorentz invariance

    Since there's another thread on the same subject in the GR forum, but on this forum about 8 months ago an interesting discussion on the same subject took place, https://www.physicsforums.com/showthread.php?t=114620, i want to draw everyone's attention on the post \#24 in that thread in which the...

    Minkowski spacetime interval's Lorentz invariance

    Maybe this is really easy, but... Can someone show me how the sign reversal between the space and time components of Minkowski spacetime make its intervals Lorentz invariant (mathematical derivation) ? Thanks... :wink:

    Four vectors and Lorentz invariance

    Does anyone know where I can find a mathematical proof that the norm of any four-vector is Lorentz invaraint?

    Q'izing GR retains local Lorentz invariance after all?

    maybe someone else can clarify; these recent papers suggest a surprising turnaround in the quantization of General Relativity, contrary to some earlier papers by other people, they predict no quantum gravity dispersion in longrange transmission of light: On low energy quantum gravity induced...
