For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery quantum fields that govern particles, and gravity has stubbornly resisted ...

Thermodynamic spontaneity—whether a reaction can go—can be measured by changes in either of two parameters: entropy or free energy.

There are moments in the history of human thought when a simple realization transforms our understanding of reality. A moment when chaos reveals itself as structure, when disorder folds into meaning, ...

Two clashing ideas about disorder inside black holes now point to the same strange conclusions, and it could reshape the ...
