The Black Hole Universe (BHU)

Résumé

Recent observations show that cosmic expansion is dominated by an effective cosmological constant. This means that we live inside a trapped surface, which corresponds to a Black Hole (BH) event horizon. We show that such Black Hole Universe (BHU) is also a solution to classical GR, where two nested FLRW metrics are connected by a BH event horizon. Observed CMB anomalies are consistent with these idea. The BHU solution can be used to model our Universe or a stellar BH inside. Observed BHs (and possibly BHs making the Dark Matter, DM) could be made of such BHUs. A BHU can originate by kinetic damping of a field into a false vacuum in an expanding background, such as cosmic inflation or a supernova explosion. In comoving coordinates the BHU is expanding while in Schwarzschild coordinates it is asymptotically static. Such frame duality allows for a Perfect Cosmological Principle where spacetime can be homogeneous both in space and time, in better agreement with relativity.
