The Shell Collapsar established in GR

A consistent description is possible for gravitationally collapsed bodies in General Relativity, in which collapse stops before the object reaches its gravitational radius. Non-singular solutions exist with the density reaching a maximum close to the surface and then decreasing towards … Continue reading

Gravitational collapse without black holes

The contemporary notion of black holes originates in Oppenheimer and Snyder’s 1939 article “On Continued Gravitational Contraction” (Phys. Rev. 56:455, 1939).  Later Roger Penrose (Phys. Rev. Lett. 14:57, 1965)  showed that the O&S metric gave rise to trapped surfaces, ie. … Continue reading
