FROZAR

A gravitationally frozen object formed during the general-relativistic collapse of stars and galactic nuclei, instead of the black holes of Newtonian gravity

A scientific and educational portal on gravitational collapse and the compact objects formed in strong gravitational fields.

Core questionWhat physical object is formed when a star or galactic nucleus reaches the ultra-compact relativistic regime?
MethodExact and approximate solutions of General Relativity, explicit simultaneity conventions and comparison with observations.
GoalTurn theoretical differences into quantitative, falsifiable observational tests.

What is a frozar?

In this project, a frozar is an ultra-compact gravitating object whose material structure becomes effectively frozen with respect to a global astronomical time during relativistic collapse. The framework studies this outcome as an alternative physical interpretation of the late stages of collapse usually described in terms of black-hole formation.

The portal will present derivations, physical explanations, criticisms, alternative interpretations and observational tests side by side.

How to use this portal
