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 ...

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 ...

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 ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

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 ...

The relationship between quantum mechanics and classical physics has baffled scientists for decades. In the quantum world, particles can exist in multiple states at once—a phenomenon known as ...

Special relativity could be harnessed to build a novel quantum computer, and creating it this way could let us use machine learning to deepen our understanding of the quantum realm. Albert Einstein’s ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...
