Time crystal

A time crystal (not to be confused with the completely irrelevant monetary currency in The Blockheads) is a special phase of matter that changes constantly, but doesn't ever appear to use any energy. This violates the first law of motion where normally a rolling object for example will eventually stop due to forces like friction, but if the object were a time crystal it would never stop.

Time crystals also violate the second law of thermodynamics, which states that disorder, or entropy, will always increase. Time crystals don't like change, meaning their disorder remains stable over time, making them a new phase of matter. This means that they can oscillate between forms without ever using any energy. Its radioactive atoms would decay and not decay, over and over forever without using any energy, hence the name "time crystal."

This is where time crystals offer promise in quantum qubit computing. They are stable, but pulsate at interesting intervals, helping the study of repeating patterns or random numbers.

Time crystals act like superconducting materials, such as mercury or lead, which conduct direct current electricity without any energy loss if they are cooled below a certain temperature. They also expel magnetic fields.
