We all know kryptonite from the Superman movies But it exists ! Taken from BBC news read whole story at BBC news.
okay....this doesn't really make sense...lol... "...large green crystals...The real mineral is white and harmless..." "The new mineral does not contain fluorine (which it does in the film) and is white rather than green but, in all other respects, the chemistry matches that for the rock containing kryptonite." that doesn't sound like "A new mineral matching its unique chemistry - as described in the film Superman Returns"
Too bad its not green and does not glow in the dark but man, its very cool that kryptonite really does exist.
lol...didn't even cross my mind (i don't think anyway...stuff crosses it so fast usually it's hard to keep up with myself)
