Black hole shock waves and sensitivity to early perturbations

Contribution grade

Quantum gravity and black holes · Scoped theoretical result, model or research proposal

Reference score165,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Shenker and Stanford used a two-sided holographic black hole model to connect a small early perturbation to a blueshifted gravitational shock wave and the loss of leading-order local correlations. In their BTZ calculation the onset time scales logarithmically with black hole entropy for a thermal-sized perturbation.

Scientific scope

Shenker and Stanford used a two-sided holographic black hole model to connect a small early perturbation to a blueshifted gravitational shock wave and the loss of leading-order local correlations. In their BTZ calculation the onset time scales logarithmically with black hole entropy for a thermal-sized perturbation. The central calculation assumes an eternal two-sided AdS black hole, classical Einstein gravity and the stated shell and holographic prescriptions. Vanishing mutual information is the leading large-N contribution for the considered intervals, not all correlations; finite spin-system numerics and string corrections are separate and limited. This is not an observed black hole, a proof of a universal chaos bound or a resolution of the firewall debate.
