What is a time crystal?
In: Planetary Science
It’s a substance whose normal resting state is oscillating back and forth between multiple states. It’s not unusual for things to oscillate back and forth, but it is very unusual for that to be their resting state.
Although, it’s not exactly a resting state, since they have to shoot a substance with a laser to create one. I don’t understand the details of why physicists consider it a resting state.
It’s also the coolest name for the most underwhelming thing in physics.
