This podcast is an attempt to record the (hopefully) coherent ramblings of three guys working their way through a physics degree. We like to listen to each other talk about physics. We will recklessly extrapolate and assume that you like to listen to us ramble too. Welcome to Quantized Ramblings

Positivity bounds and gravity

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.
