Carlo Rovelli is a physicist at Aix–Marseille University, Marseille, France, and an associate member of the Rotman Institute of Philosophy in London, Ontario, Canada. Nature seems to have played us ...

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...

An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...

Some random article came up on google for me about how there is a new attempt to reconcile both QM and Relativity through some space time dimension field. The point being that wouldn't such a theory ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...

Einstein was awarded the 1921 Nobel Prize for a theory that half of the people might not even have heard of. His Theory of Relativity, though world-changing, was not cited. Yet while delivering his ...
