Maybe not. From the article: "But the new calculations, though inspired by string theory, stand on their own, with nary a string in sight. Information gets out through the workings of gravity itself — just ordinary gravity with a single layer of quantum effects...Over the past two years, physicists have shown that the entanglement entropy of black holes really does follow the Page curve, indicating that information gets out. They did the analysis in stages. First, they showed how it would work using insights from string theory. Then, in papers published last fall, researchers cut the tether to string theory altogether."
Sounds like there is no dependency on string theory.
- tines 6y agoI took that to mean that they don't use string theory to prove anything per se. But it sounds like they got "insights" from string theory, which seems like it was useful for once? IANAP.
- ojnabieoot 6y agoI am a mathematician with some physics background and have been skimming this article: they took mathematical inspiration from string theory in terms of how they formulated the path integrals, but the physical concept of a string doesn’t actually appear. So string theory provided analytic tools but didn’t actually provide physics.
