Why Do Physicists Keep Finding New States of Matter?
There's far more than the three or four you're thinking of.
Ah, yes, the three states of matter: Solids, liquids, and gases. What a simple way to understand our physical world.
Of course, if you remember a bit of high school science, you probably recall a fourth state of matter, plasma. And if you pay attention to science news, you’ve probably heard of another, Bose-Einstein condensates. So, five states of matter.
