Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Quantum gravity challenges the classical notion of spacetime by positing that the smooth, continuous fabric described by general relativity may arise from more fundamental, non-spatiotemporal entities ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

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

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

Hoboken, N.J., July 14, 2025 — Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

(via PBS Space Time) To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could just physics smarter and build one on a lab ...

Quantum theory has been remarkably successful ever since its inception 100 years ago. And yet, there is a glaring mismatch between the discrete, quantum nature of matter and the apparent continuous, ...
