Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser ...

Physicists have shown that particles produced in collimated sprays called jets retain information about their origins in subatomic particle smashups. Physicists at the U.S. Department of Energy's (DOE ...

A boiling sea of quarks and gluons, including virtual ones—this is how we can imagine the main phase of high-energy proton ...

Data from past proton-electron collisions provide strong evidence of entanglement among the proton's sea of quarks (spheres) and gluons (squiggles), which may play an important role in their ...
