The Machian origin of linear inertial forces from our gravitationally radiating black hole Universe

Abstract

Gravitational radiation of the Universe (U), accelerated with respect to linear non-inertial frames, accounts for linear inertial forces provided accessible masses, i.e. those within the Hubble radius, obey $$\tfrac{{2GM_U }} {{c^2 R_U }} = 1$$ . This implies that we must be living in a black hole Universe, whose Schwarzschild radius is determined by the Hubble constant. Thus non-inertial frames represent the probe of the existence and substantial role of gravitational waves in the Universe, accounting for part of its of dark energy content.
