Physicists uncover hints of time crystal in children's toys that are sold online. The discovery adds more questions on how time crystals are exactly formed. Crystals such as salt or quartz contain ...

Yale physicists have uncovered hints of a time crystal — a form of matter that “ticks” when exposed to an electromagnetic pulse — in the last place they expected: a crystal you might find in a child’s ...

Physicists have spotted signatures of a time crystal in a material that might be found in a child’s toy. So-called time crystals are those in which the atoms follow a repeating pattern in time, rather ...

In 2012, Nobel Prize-winning scientist Frank Wilczek proposed the existence of a new type of crystal. While most crystals have a structure that repeats in two or three dimensions, Wilczek imagined a ...
