Black Holes or Objects without Event Horizon?

Abstract

This paper examines the question of whether the generally accepted interpretation of a supermassive object in M87 is the only one possible. There are grounds for this, in particular, due to the detection of a magnetic field in its vicinity. For this purpose, the stability of self-gravitating objects is investigated based on the correct definition of the energy of gravitation in the framework of the bi-metric approach to the theory. It is shown that supermassive objects can be stable configurations of a partially degenerate Fermi gas, the radius of which is less than their Schwarzschild radius.
