If we're gonna go into physical impossibilities, Adamantium and Vibranium are just that. If I'm right in saying they are elements, they just can't exist. Every element up till no. 112 or something already exists and has existing properties that aren't that of Adamantium or Vibranium. Its atomic number can't be higher than about 83 though, because anything higher than that is constantly undergoing alpha radiation (changing into another element). And it can't be somewhere between each element, because the defining feature of each element is the atomic number (number of protons), and each number from 1 to 112 is already taken, and you can't have 53.5 protons or something... But yeah, this is fiction anyway...
