No one thought that Clock could die. His chiming breath fell silent and the cells grew anxious. Then She spoke. “Hello. My name is Time.”

Physicists at Harvard University have created a new phase of matter, called time crystals, in which atoms repeat a pattern of motion in time rather than space. These crystals could lead to the creation of a new generation of atomic sensors and could also lead to impacts in atomic clock research. // Alex Massey //
