The Importance of Open Science

Open science is important and useful, but the ways in which it manifests itself are going to be different for different kinds of science. Chris Gunter says if we discovered a particle that violated the equivalence principle, how big of a disruption would that be to the core theory? Consider a scalar factor between the two, zero gravitational mass or negative gravitational mass. Can a particle such as this be modeled under GR? I think there's a couple things to say about this question.
