    Special Relativity - Transformations and Equivalence Principle

    I am going to try to explain relativity without light or maxwell's equation. Light or Maxwell's equation or electromagnetism has nothing to do with relativity. a) The speed of light (and not light itself - note the difference) has something to do with it. b) The fact that M&M used light...

    Graviton and the equivalence principle

    I posted this in general physics, but I didn't get an answer, so I'll try again here: Einstein's theory of general relativity was motivated by his equivalence principle, that no experiment can distinguish between an accelerated frame and a still frame under the influence of gravity. But if...

    A New Test of the Equivalence Principle?

    The Eotvos type experiments test the equivalence principle by comparing the inertial accelerations of bodies of different compositions within a gravitational field. In short they test whether feathers and cannon balls fall at the same 'rate'. But has anybody tested whether particles and...

    Dought regarding equivalence principle

    i have some doughts regarding the principle of equivalence.we have seen that the inertial mass and gravitational mass are same.now consider the nucleus where in nucleons are binded due to which there wiil be mass reduction,this is inertial mass.then how come there is decrease in gravitational...

    Equivalence principle + light speed postulate =

    It seems to me that Einstein's equivalence of gravitational acceleration and non-gravitational acceleration, when combined with his constancy of light speed in vacuuo, should yield a constancy of gravitational speed in vacuuo.

    Questions of the equivalence principle

    Being full of doubts I have some questions of the equivalence principle. 1. In the presence of gravitational fields the Einstein Equivalence Principle (EEP) is a necessary and sufficient condition for the Principle of Relativity, (PR). Here I summarise PR as the doctrine of...
