| Title: | The Weak Gravity Conjecture and Repulsive Forces |
| Date (JST): | Tue, May 21, 2019, 15:30 - 16:45 |
| Place: | Seminar Room A |
| Abstract: | The Weak Gravity Conjecture postulates the existence of a particle with charge-to-mass ratio larger than that of an extremal black hole in any consistent quantum gravity. I review the evidence for the conjecture and some of its strong forms, and compare it with a subtly different conjecture that requires a charged particle that repels its identical copy at large separations. I discuss the evidence for this "repulsive force conjecture" and comment on its relationship to black holes, as well as its potential application to theories without gravity. |
