摘要: By matching across a surface of constant time, it is demonstrated that the spacetime for radiation-dominated Einstein–de Sitter universe can be directly matched to matter-dominated universe. Thus, this serve as model filled with radiation suddenly converted matter and antimatter, or antimatter annihilates leave radiation. This shown hold asymptotically cosmological black hole spacetimes, yielding simplistic models primordial holes evolve between being in universes universes.
