How can the newly discovered form of matter time crystals, how can they vibrate without any outside force? Doesn't that defy the currently accepted laws of physics?

The answer is science

A new kind of matter known as a "time crystal" has been created by two teams of scientists in a feat once considered impossible.

Normal crystals, anything from diamonds to snowflakes, have atoms arranged in a repeating three-dimensional lattice.

However the atoms in time crystals repeat a pattern across the fourth dimension, time.

This essentially means they should oscillate forever without any external influence.
