Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths generalize the familiar trajectories predicted by Einstein’s general theory of ...

Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...

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 ...

Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to ...

Breakthroughs in science often begin with a simple question and years of tireless exploration. From the way tiny molecules slip through microscopic pores to the staggering behavior of matter near ...

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 ...

A South Korean physicist has proposed a theoretical framework that could support the unification of quantum mechanics and the ...

Unifying quantum mechanics with general relativity is the ultimate dream — or nightmare — of physics. It would be a way to finally describe the force of gravity with the tools of quantum mechanics, ...
