Positivity bounds and gravity Quantized Ramblings

- Physics
In this episode, we begin by reviewing the weak gravity conjecture. We then discuss such "swampland conjectures" from the EFT perspective- in the form of positivity bounds, and discuss in detail the UV completion of dimension 6 operators. We then discuss Witten's classic work on the ADM mass positivity; seeing how all these ideas are elegantly related. We ramble about the status of global symmetries in quantum gravity, and we conclude with a rant about linearly designed curricula.
