Gravitation and Conservation Equations. Fluids and Elastic Waves

Abstract

Let h be Cavendish’s constant. Then in view of (16.10)₁ and (21.1) the Einstein non-cosmological gravitation equations—on which general relativity is based—can be written in the form

$$ {A_{\alpha \beta }} + \frac{{8\pi h}}{{{c^4}}}{u_{\alpha \beta }} = 0 where {u_{\alpha \beta }} = \rho {u_\alpha }{u_\beta } \cdots $$
