We present and interpret two non-singular BH solutions, BH.fv and BH.u., within the laws of classical General Relativity. These solutions look like a singular Schwarzschild BH from the outside. BH.fv corresponds to a false vacuum without matter. BH.u also has matter and radiation inside, which are expanding or contracting. For the inside comoving observer this BH looks like an homogeneous and isotropic universe. The metric of our universe exactly corresponds to such BH.u with 5.8 × 10 22. The Big Bang is just an illusion and our universe could be much older than previously estimated. Primordial inflation, the measured cosmic acceleration, CMB anomalies and tensions in measurements of cosmological parameters all provide independent observational support for such BH.u solution.
