Focus on bimetric theory

It goes without saying that finding answers to questions raised by the Standard Model and General Relativity remains a huge part of theoretical physics. Recent developments in bimetric theory, a topical review published in Journal of Physics A: Mathematical and Theoretical is the second most most highly cited article in the journal from 2016. Here we talk to one of the authors of the review, Angnis Schmidt-May, from Ludwig-Maximilians-Universität München, to discover why this field is so active and what discoveries she’d like to see.
