Physicists Adrien Fiorucci and Marios Petropoulos on France Culture

Despite the undeniable successes of Albert Einstein’s theory of general relativity, scientists still have a long way to go in understanding gravity.

In this context, researchers at the CPHT, including Marios Petropoulos and Adrien Fiorucci, are pioneering an approach that seeks to extend the “holographic principle.”

Behind this mysterious name lies a mathematical correspondence between a four-dimensional theory (three spatial dimensions and one temporal dimension, as in general relativity) and a theory with one fewer dimension (which can be described as the “edge” of a four-dimensional space).

CPHT researchers have made a significant step toward establishing such a correspondence in the case where spacetime has very realistic features (in particular, a slightly positive curvature). This could open up new avenues for reconciling general relativity and quantum physics.
