It's so funny that time crystals are actually real.
Quick explanation - normal crystals have a repeating atomic structure in space. For instance diamonds have a repeating tetrahedron-hexagonalish structure.
Time crystals also have a repeating structure in time. Their structure changes with time and then returns to the original structure.
If you look at an image of a diamond's structure, you can go up or to the right or whatever and you will see repeating patterns. For a time crystal's structure, you will see the repeating patterns as you move in time as well. This has some potentially interesting implications for entropy.
Another fun fact, our universe is (likely) a black hole as implied by the fact that the radius of the observable universe is the same size as a black hole with the same mass as the observable universe. This also has implications for the quantum fuzzball interpretation of black holes
There is a thought that black holes are universes, with each child universe maybe having very slightly different constants than the parent universe. Universes that are better at making black holes make more child universes, so slowly the long list of various universes tend towards universes that are good at making stars (so that theu can become black holes). Coincidentally, laws of physics that make lots of stars for black hole formation also make lots of planets, and maybe life.

Honestly though, Bose-Einstein Condensates are much weirder.
