Interesting fact about matter.
Everybody knows that there at least three states of matter: solid, liquid, and gas. If you’re a little bit more versed in physics, you also know about the fourth fundamental state of matter called plasma — a hot ionized gas, with prime examples including lightning or neon signs. But beyond these common states of matter, scientists have discovered a myriad of exotic states of matter that occur under special conditions. One of them is the Bose-Einstein condensate, where atoms chilled to only 0.000001 degrees above absolute zero start behaving like waves, rather than particles as they ought to on the macroscopic scale. Essentially, the atoms behave like one super atom, acting in unison.
Another interesting exotic state of matter is represented by time crystals — regular, boringly ordered crystals with a twist: A fourth dimension, time, is added so that the material exhibits different periodic structures over time. What makes these crystals particularly remarkable has less to do with the fact that they repeat in time but rather more with the fact that they’re intrinsically out of equilibrium. Because time crystals are never able to settle down, say into a diamond or ruby, there’s a lot we can learn from them.
