Black Hole Entanglement Shuffles Correlations at the Scrambling Time, New Study Finds
A new theoretical study shows that at the scrambling time, black hole mutual information vanishes between exterior regions while diverging ...
Charged Black Holes Grow Scalar Hair When the Charge Crosses a Critical Threshold
A new theoretical study shows that Einstein–Euler–Heisenberg black holes spontaneously grow scalar hair in two distinct regimes, with the sign ...
Echoes of Light Near the Horizon Could Expose Black Hole Impostors
New simulations show that a reflective surface near a black hole's horizon would imprint delayed electromagnetic echoes in the light ...
Black Holes With Extra Horizons Could Shield Falling Objects From Deadly Tidal Forces
A new theoretical study of multi-horizon black holes in nonlinear electrodynamics shows that classically forbidden regions can bounce infalling particles ...
Exotic Black Holes Grow Hair and Reveal a Surprising Entropy Ceiling
A new theoretical study shows that charged Taub–NUT black holes in Gauss–Bonnet gravity spontaneously grow scalar hair and obey a ...
Quantum-Corrected Black Holes Grow Scalar Hair in a Narrow Window of Stability
A new theoretical study shows that quantum-electrodynamics-corrected black holes with multiple horizons can spontaneously grow scalar hair, but only within ...
Magnetic Reconnection Could Mine Energy From Black Holes Beyond Einstein’s Kerr Ideal
A new theoretical study shows that magnetic reconnection can efficiently extract rotational energy from a non-Kerr compact object, and that ...
How Charged Black Holes Could Reveal Hidden Corrections to Einstein’s Gravity
A new theoretical analysis shows that higher-curvature corrections from effective field theory would measurably shift the photon spheres, quasinormal modes, ...
Two Faint Matter Shells Can Team Up to Destabilize a Black Hole
