Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

Lorentzian geometry forms the mathematical cornerstone of modern spacetime theory by providing a framework in which the causal structure and metric properties of the universe can be rigorously ...

Physicists from the Eötvös Loránd University (ELTE) have been conducting research on the matter constituting the atomic nucleus, utilizing the world’s three most powerful particle accelerators. Their ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...
