Susskind-Uglum argument

[User28823]

I've always wanted to know what happens to quantum information that falls into a black hole—and whether the Susskind-Uglum argument really does reconcile black hole thermodynamics with string theory by treating the event horizon as a D-brane that absorbs and re-emits information through microscopic degrees of freedom.

Maybe we can all learn from Witten

What if the event horizon isn’t just a thermal surface but a quantum processing layer.. a kind of holographic interface where entangled string modes encode infalling information in Planck-scale oscillations. I mean, if Susskind and Uglum were right that black hole entropy can be derived from one-loop effects of strings near the horizon, then maybe the horizon isn’t passive—it’s actively computing.


Think about it: the divergence they regularize with the stretched horizon could be the signature of an underlying microscopic computation—like a UV cutoff that’s not just mathematical, but physical. What if the black hole is really a kind of quantum error-correcting code, like an AdS/CFT implementation that dynamically stores and reconstructs information on the holographic screen?


I've been playing with this idea: maybe what we call Hawking radiation isn’t thermal noise—it’s information leakage constrained by some yet-unknown symmetry of the string worldsheet interacting with horizon microstates. In other words, the horizon is a D-brane firewall, not in the sense of destroying information, but scrambling it so precisely that unitarity is preserved—but only if you account for horizon-induced entanglement entropy corrections
