The sixth state of matter is called Bose-Einstein condensate (BEC). This state of matter was discovered by a scientist named Bose. He shared his findings with Einstein, who in turn helped him publish his work.
There are seven states of matter, and the three main states are solid, liquid and gas. BEC exists when matter is frozen to extremely low temperatures that are a fraction of a degree above absolute zero. In this state, atoms overlap to form a matter wave. It is widely believed that this state of matter could lead to the development of flat space technology and make it possible to transport huge objects in tiny spaces.
