Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

A team of physicists has uncovered a surprising new way to explore one of science's greatest challenges: uniting the two fundamental theories that explain how our universe works—Einstein's theory of ...

A null boundary carries a degenerate signature (0++) metric, which is obtained by taking the pull-back of the four-dimensional line element to the boundary. Credit: Classical and Quantum Gravity (2025 ...

By Anil K Rajvanshi A new theory in Physics, as enunciated by Gunther Kletetschka, tries to unite quantum physics and gravity ...

A century since Werner Heisenberg changed the course of physics, five of the world’s leading physicists examine the greatest achievements of quantum mechanics and look forward to the next 100 years, ...
