Comic book physics question: Vibranium (a metal which exists only in the Marvel Universe) possesses "the ability to absorb all vibrations in the vicinity as well as kinetic energy directed at it. The energy absorbed is stored within the bonds between the molecules that make up the substance. As a result, the more energy vibranium absorbs the tougher it becomes." If I were to forge a hammer from vibranium and subsequently strike myself in the head with it with all the strength I could muster, would I feel a thing? Or would the entire impact be absorbed? If so, Black Panther has been missing out on some pretty entertaining party tricks.
