@HotRod22 The element Tony uses in his new Arc reactor in Iron Man 2 was dubbed the "Howard Stark element".

Think about the characteristics of elements and how that affects their application. Iron isn't used in nuclear reactors. Uranium isn't used to insulate engine bays or space craft. And gold isn't used to build buildings or bridges. We have seen in the comics and the MCU that vibranium is used for its strength and durability, not its energy output.

And I'm sorry, but if a theoretical physicist approached the Nobel committee and declared they'd discovered a method for humans to effortlessly travel faster than the speed of light, they'd want to see proof. They wouldn't accept that physicist saying "prove I haven't". The topic at hand is closer to science and engineering, not a court of law where a defense lawyer only has to provide reasonable doubt.

If all we have is circumstantial evidence of what the Mark XLV is made of, then I'd say it leans more towards the suit not being made of vibranium. But at the same time I could make an argument for how and why I think it is.
