In my Science class we only learned about 4 states of matter. I recently discovered that in 1995 someone discovered a fifth! The fifth state of mater is called Bose-Einstein condensate. They called it this because in the 1920's Albert Einstein and Satyendra Bose predicted a new state of matter. This state of matter is the exact opposite of plasma. Plasma is an over-active state of matter and Bose-Einstein condensate is an under-active state. Bose-Einstein condensate is only a three billionths of a degree higher than absolute zero. In case you are wondering what absolute zero is, it is the temperature at which all molecular movement stops. You will not see this often in someones house. This is an extremely dangerous state of matter if you compress it under a lot of pressure. It will make a black hole!
