Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

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

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

The original version of this story appeared in Quanta Magazine. 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 ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." When you purchase through links on our site, we may earn an affiliate ...

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 — ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...
