I take chemistry and not physics so I dont know if any of these will clash with physics? Some obviously won’t but some may
-The validity of the expansion theory of the universe in terms of (quantum) physics
-The likelyhood of AI taking over medical industry jobs (that may be more engineering/medical based though)
-The chemistry and psychology behind the placebo effect and its possible future usages
-The environmental benefits of nuclear fission Vs fusion or the likely hood if it becoming a worldwide use energy production (i cant remember if its fission or fusion which is the one currently in development)
-Cost benefit analysis of environmental energy production
Those are some off the top of my head Hope this helped!!
