Black star (semiclassical gravity)

Common card · No. 489763

A black star is a gravitational object composed of matter. It is a theoretical alternative to the black hole concept from general relativity. The theoretical construct was created through the use of semiclassical gravity theory. A similar structure should also exist for the Einstein–Maxwell–Dirac equations system, which is the (super) classical limit of quantum electrodynamics, and for the Einstein–Yang–Mills–Dirac system, which is the (super) classical limit of the standard model. A black star does not require an event horizon, and may or may not be a transitional phase between a collapsing star and a singularity. A black star is created when matter compresses at a rate significantly less than the free fall velocity of a hypothetical particle falling to the center of its star. Quantum processes create vacuum polarization, producing a form of degeneracy pressure preventing spacetime (and the particles held within it) from occupying the same space at the same time. This vacuum energy is...
