The universe is getting more disordered, entropy is growing -- this is the second law of thermodynamics. But according to quantum theory, entropy should actually stay the same. Scientists took a ...

Now, researchers have the first direct evidence — after using a trick to infer subatomic particles' entropy. Scientists have peered inside protons and discovered that quarks and gluons ...

By comparing the particle sprays to calculations of their entropy, the physicists discovered that the quarks and gluons inside the colliding protons existed in a maximally entangled state ...
