| Title | De Sitter Bubble as a Model of the Observable Universe |
| Author | Larissa Borissova |
| Abstract | Schwarzschild's metric of the space inside a sphere of incompressible liquid is taken under focus. We consider a particular case of the metric, where the surface of the liquid sphere meets the radius of gravitational collapse calculated for the mass. It is shown that, in this case, Schwarzschild's metric transforms into de Sitter's metric given that the cosmological λ-term of de Sitter's metric is positive (physical vacuum has positive density). Hence, in the state of gravitational collapse, the λ-field (physical vacuum) is equivalent to an ideal incompressible liquid whose density and pressure satisfy the equation of inflation (noting that positive density yields negative pressure). This result is then applied to the Universe as a whole, because it has mass, density, and radius such as those of a collapsar. The main conclusion of this study is: the Universe is a collapsar, whose internal space, being assumed to be a sphere of incompressible liquid, is a de Sitter space with positive density of physical vacuum. |
