## Summary

Anthropic says Fable 5.2 found the exact limit of the simplest version of modular bootstrapping, a 15-year-old physics technique. The technique is used to rule out candidate theories of quantum gravity in theoretical universes.

In the second physics problem, Fable 5.2 found the exact limit of the simplest version of a 15-year-old technique known as “modular bootstrapping.” The technique is used to rule out candidate theories of quantum gravity in theoretical universes.
