In a groundbreaking scientific achievement, researchers have successfully created a new phase of matter known as time crystals, which fascinatingly exhibit behaviors akin to perpetual motion. We will ...

Imagine a clock that doesn’t have electricity, but its hands and gears spin on their own for all eternity. In a new study, physicists at the University of Colorado Boulder have used liquid crystals, ...

Scientists have developed the first-ever time crystals that are visible to the human eye, and they could one day make their way onto $100 bills. The time crystals emerge from the kinks that appear ...

Researchers have developed a blueprint for weaving hopfions—complex, knot-like light structures—into repeating spacetime crystals. By exploiting two-color beams, they can generate ordered chains and ...
