Well about being a candidate, there are some issues:
1. My physics is kinda undergrad level still, thus there isn't really any good things to talk about
2. My speciality is mostly chemistry thus any thesis level stuff I can talk about is gonna be atmospheric chemsitry and molecular dynamics
3. The most content-ful thing I can talk about that is closest to physics is that scifiphysics mix of my time travel model, which a bottleneck was just identified recently by the h barers thus it is shelved
