Einstein's equation of gravity
WebJan 10, 2024 · Can someone derive Einstein's general relativity field equation for one spatial dimension and one time dimension from the beginning? I think this will help many beginners to get a feel and understand ... or a matter Lagrangian with other fields if coupling gravity to another theory. The Einstein field equations follow from the variation with ... Web1. This is not the best way of explaining Einstein's work on GR. I remember telling my uncle that Einstein discovered GR to satisfy Lorentz invariance in gravity. He said that had little or nothing to do with it, and that it is really easy to create a relativistic extension of Newtonian gravity (a non GR extension).

WebOct 8, 2024 · The Field Equations of Gravitation. By A. Einstein. I have shown in two recently published reports, [1] how one can arrive at field equations of gravitation, that are in agreement with the postulate of general relativity, i.e. which in their general form are covariant in respect to arbitrary substitutions of space-time variables.
WebJan 28, 2024 · Another difference between Newton and Einstein is that Einstein’s theory recognises that the source of gravity is not mass, as Newton believed, but energy, one form of which is mass. This means that all forms of energy have gravity: sound energy, heat energy and so on.
