The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the matter field and the geometry. Credit: Physical Review D (2025).
It measures 90 mm in height, 965 mm in length, and just 14 mm in thickness. This geometry already shows the different angles the two companies take. When it comes to raw energy storage ...
