One of the greatest challenges of modern physics is to find a coherent method for describing phenomena, on the cosmic and microscale. For over a hundred years, to describe reality on a cosmic scale we ...

Alena Tensor in flat and curved space-time We used Alena Tensor to describe a system with an electromagnetic field, obtaining three forces in flat space-time: electromagnetism (which is not surprising ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

New spacetime model: Researchers reframed Einstein’s equations to reveal gravitational structures that can remain connected during spacetime evolution, inspired by plasma physics. Conserved quantities ...

A breakthrough in optics could revolutionize the study of space-time and quantum phenomena, and make our ultimate experiment possible. Share on Facebook (opens in a new window) Share on X (opens in a ...

Einstein’s big shift: He replaced Newton’s pull with curved spacetime, showing gravity as geometry rather than a force. Time isn’t universal: Special and general relativity reveal that motion and ...

Hoboken, N.J., July 14, 2025 — Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure ...
