Time crystals 'impossible' but obey quantum physics
Scientists have created the first "time-crystal" two-body system in an experiment that seems to bend the laws of physics.

Some of the most profound predictions in theoretical physics, such as Einstein's gravitational waves or Higgs' boson, have taken decades to prove with experiments. But every now and then, a prediction can become established ...

(PhysOrg.com) -- As every young science student knows, moving objects have kinetic energy. But just how much energy does something need to move? In a new study, a pair of physicists has shown that its theoretically ...
(PhysOrg.com) -- Generally, scientists prefer to avoid the concept of perpetual motion. The idea of a machine that could produce movement that goes on forever, and using that movement to generate an endless stream of energy, ...
