Vibranium, the metal in the movie, doesn’t exist in real life, but this substance might be the closest we can get. In the Marvel Universe, Wakanda is mineral rich thanks to a substance called vibranium deposited on Earth 10,000 years ago by a meteorite. Think oil in the Middle East or lithium in Chile.
Vibranium appears frequently in the Marvel Universe. It is most known for being used in the construction of Captain America’s Shield, the vibranium was of an ultra-resilient vibranium-iron alloy created by Dr. Myron MacLain. The formula has never been reproduced despite numerous attempts.
