| Aug 28, 2021 at 20:59 | comment | added | Connor Behan | What you might've read is that string theorists make use of dimensional reduction which was originally formalized as part of a different theory by Kaluza and Klein which attempted to unify gravitational and electromagnetic fields back when people thought these were the only two forces. | |
| Aug 28, 2021 at 20:57 | comment | added | Chiral Anomaly | @SamCottle It has nothing to do with electromagnetism. Perturbative string theory automatically has massless spin-2 particles, and any reasonable theory with interacting massless spin-2 particles has gravity. For a nonperturbative perspective, the AdS/CFT correspondence is the most-studied framework so far. (That's not an answer, just a couple of sentences with keywords to point you in the right direction, because I don't think a one-post answer is feasible.) | |

| Aug 28, 2021 at 20:23 | comment | added | Sam Cottle | No, I don't. But your best efforts to explain it here (how string theory explains gravity that is) would be much appreciated. | |
| Aug 28, 2021 at 20:22 | comment | added | Prallax | I'm afraid that a post on SE would not be enough to explain "exactly" how string theory yields gravity. Besides, do you happen to remember where you have read that "string theory explains gravitation via invoking quanta of the electromagnetic field to transmit the force of gravity"? | |
