The Same Parameter That Controls Neutron Stars Also Stops Black Hole Singularities

Key Points

• The study aims to explore how gravitational collapse affects singularity formation in black holes and neutron stars.
• Analyzed gravitational collapse conditions and effects on singularity formation using CCEGA framework.
• Calculated critical density at which singularity formation is arrested.
• Predicted gravitational wave (GW) echoes and compared them to neutron star merger signals.
• Identified critical density ρ_c = 7.4 ρ_nuc leading to G_eff → 0, stopping singularity formation.
• Determined the final interior radius of black holes and the tidal charge value.
• Predicted GW echoes at approximately 4.76 ms, distinct from neutron star mergers.
