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 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 new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

Alyssa Ney is professor and chair of metaphysics at the Faculty of Philosophy, Philosophy of Science, and Religious Studies at Ludwig-Maximilians University Munich, Germany. This week, physicists are ...
