>>10995418High energy physics is a huge topic, covering much of modern physics. The basic idea is that it concerns phenomena that happen at energy scales much higher than what is relevant to nuclear physics. Alternatively, phenomena that occur on distance scales comparable or smaller to the size of the proton. In effect, it's a catch-all for people who wish to investigate quantum mechanics and quantum field theory using math and programming.

>>10995418 brought up a particular line of research among the high energy community right now, which is a correspondence between gravitational theories and conformal theories, which have found success in describing phase transitions.
>>10995418>>10995427why are you being a dick?
>>10995513which part of it would you like explained? I'm not well-versed in SUGRA or string theory, but I know some stuff about CFTs and S-dualities (of which I think this is an example).
