Abstract
Since the general theory of relativity (GR) meets some difficulties, it seems that new considerations on the ether theories of gravitation in the history are needed. A theory of gravity based on some new concepts of ether and particles is briefly reviewed. In this theory, the universe is filled with a kind of fluid which may be called the \(\Omega (0)\) substratum, or we say the gravitational ether. Particles are modeled as sink flows in the \(\Omega (0)\) substratum. Newton’s law of gravitation is derived by methods of fluid mechanics. Thus, gravity is interpreted as attractive force between sinks in the \(\Omega (0)\) substratum. The theoretical calculation of the cosmological constant (CC) based on a mechanical model of vacuum is briefly reviewed. A proposed solution of the cosmological constant problem (CCP) is discussed. Inspired by the association of the gravitational wave (GW) event GW170817 and the gamma-ray burst (GRB) event GRB 170817A, we propose a theoretical calculation of the mass density of the electromagnetic ether.
