Which is the fifth state of matter?
Okay, if you are under 15 you should accept that there are three states of matter (solid, liquid and gas). If, on the other hand, you are over 15 you should be aware of four (the fourth being plasma). If you are over 17 you should know about another (amorphous solid – glass belongs to this state). As you get older in your physics career you will learn that there are more than 10 (I lost count) states of matter, including: Bose-Einstien condensate Supersymmetrical solid Superfluid …and many many more. Each of these states of matter satisfy the requirements that make them equally as valid as ‘solid, liquid and gas’. So, depending on your schooling, the fifth state of matter would depend on the order in which you write them. To Babak, what on earth does your dream-world have to do with Physics?
