(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 ...

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 ...

(via PBS Space Time) To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity. And to do that, most physicists believe we need a ...

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 ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

The universe thrums with quantum fields; and the particles of matter and force emerge as vibrational manifestations of the deep symmetries of these fields. The layers and reflections of those ...

Gravity has become an unlikely viral villain, blamed for an imagined global blackout in which the planet briefly lets go of everything that is not nailed down. At the same time, some of the most ...

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

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 ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...
