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?

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.

i believe it is b. what was the cause of the big bang

hope this !
