Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

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 — ...

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 ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

What exactly is … everything? What is space-time? At one extreme, you’ve got the weird rules of quantum physics that deal with subatomic particles. At the other extreme, you’ve got the vast expanses ...

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

It feels so obvious that time moves forward that questioning it can seem almost pointless.

The Earth’s gravity, manifested as curvature in space and time, is expected to alter the rules of standard quantum theory. An experiment consisting of three quantum computers at different elevations ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...
