CONT

... other types of exotic matter have been observed in reality. One example is what is called a Bose-Einstein condensate, which is a state of matter that occurs at extremely low temperatures near absolute zero. In a Bose-Einstein condensate, atoms clump together and behave as if the whole group were a single atom.
