I must be a real old timer at the tender age of 33 because I can remember when we had 4 phases of matter: Vapor, Liquid Solid and Plasma. But the first three I mentioned are all you or I run into on a day to day basis. I guess you could say it's a good thing we don't run into plasmas, they're freakin' HOT (the Sun is a plasma)
Now they are coming fasting and furious, Added just recently are Bose-Einstein condensate, A Fermionic Condensate and A New, Supersolid, Phase Of Matter and these all exist under conditions approaching absolute zero.(glad I don't bump my knee on this stuff too).
OK, My math says 7, of course antimatter would double that and mirror matter(if it exists) would double it again.
That's a freaking lot of phases! So 28 kinds of matter. Makes me wonder, what does the future hold?
