I don't know, the material is a ceramic made of a powdered lead, copper, sulphur, phosphorus and oxygen heated up together. It's not some advanced meta material which if true it's amazing this was not discovered earlier but let's just hope it is.
This was intended as a joke, but since most raw materials in the universe are the same, extraterrestrials deriving novel combinations is just as, if not more likely, than meta materials etc.
