What is the strongest material known to mankind?

You really can’t blame Wakanda for holding on to all of that vibranium. I mean, just admit it — you, like everyone else in the movie theater, immediately wanted as much of it as you could get as soon as you learned about it, even though you knew it wasn’t even real. It’s what Captain America’s shield is made of, for crying out loud!

Of course, a fictional material is a lot easier to make sound indestructible than something real, especially when we have all sorts of doo-dads these days that are designed to just destroy stuff. Plus, if we had vibranium in real life, we’d probably just end up doing something boring with it like using it in cellphones.

But let’s say we actually decided to do something cool for once and use the strongest material known to humans to build a Captain America-like shield — what substance would we be using?
