Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether ...

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

A new hypothesis called the “quantum memory matrix” could solve long-standing physics questions, including the Black Hole ...

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

Gravity is the most familiar of nature’s forces. It keeps our feet planted on the ground and dictates the movements of ...

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, ...

Quantum field theory is different: as I mentioned earlier, it is a relativistic theory, which means that it works no matter how you are moving through the Universe. Unfortunately, perhaps the only ...

At the heart of the proposal is a rethinking of how gravity behaves at a fundamental level. While the electromagnetic, weak and strong forces are all described using quantum field theory — a ...

Historically, quantum-field theory challenged the fabric of spacetime, suggesting that it emerges from a nonlocal source. It self-organizes in the heat of spacetime and causality, ...

The quantum theory of gravitation, effective field theories and strings: Past and present May 7, 2024 A proposed experiment to test whether gravity behaves as a quantum entity when measured ...

This theory merges classical field theory, quantum mechanics, and special relativity. It explains how particles interact through gauge fields—mathematical constructs that ensure the symmetries ...
