According to the authors, their study proposes a new model of non-local interaction between the DM of a galaxy and gravity, which could provide a fresh perspective on the still-mysterious nature of this invisible mass. As Einstein said, when describing General Relativity in a nutshell, “Matter tells spacetime how to curve, and curved spacetime tells matter how to move.

This is confirmed by observations and represents one of the biggest issues in Cold Dark Matter models in Newtonian gravity.”
