The Mass of Our Observed Universe2023.01.27 10:07 - Katarzyna Kuźniar
We argue that if the Universe around us has a finite mass, M, current observations indicate that M is inside its corresponding gravitational radius, rS=2GM. This then becomes a boundary for the inside dynamics that could explain cosmic acceleration without the need of Dark Energy. Such BH Universe (BHU) is observationally very similar to the LCDM morel, except for the very large scale perturbations, which are bounded by rS. We discuss possible origins and observational test for such BHU.
