String theory yields finite quantum gravity amplitudes
When you quantize gravity as a particle (graviton) using ordinary particle-physics rules, higher-loop corrections diverge; but treating particles as relativistic vibrating strings automatically includes a graviton among the excitations and renders the previously infinite physical amplitudes finite without anything being put in by hand.

“when you try to compute these corrections to physical processes, you find that what used to be infinite suddenly becomes finite. And that was remarkable because it wasn't put in by hand that somehow magically it becomes finite”
