With Captain America Civil war
released, Lets answer a burning question!
Could Vibranium be destroyed?
The answer is yes, if you follow the comics. Vibranium has been destroyed several times in the comics according to Wikipedia here are some of them:
1.In The Avengers #215–216,
the Molecule Man used his total control over matter to disintegrate
the shield, along with Thor's hammer, Iron Man's armor, and
the Silver Surfer's board.
2.During the 1984-1985 Secret Wars limited
series, the shield is partially destroyed by Doctor Doom, who has stolen
the power of the godlike being known as the Beyonder.
3. During the 1991 miniseries The
Infinity Gauntlet, Thanos shatters the shield with a blow of his
fist while in combat with Captain America.
4.In Avengers Vol. 3 #63
(March 2003), an enraged Thor, wielding the Odin force, dents the
shield.
5.In Thor Vol. 2 #73 (January
2004) an enraged King Thor with Rune Magic, destroyed the shield, killing Steve
Rogers with it.
6.During the 2011 miniseries Fear
Itself, the Serpent, the Asgardian god of fear and brother
to Odin, breaks it in half with his bare hands.
But wait, wasn't the answer just too easy? What
if we actually had a metal that resembles Vibranium or has its properties. What
if Vibranium existed in our universe with the same properties?
If Vibranium could act like an immovable body (On its
own), so what does every immovable object need? An Unstoppable force! Just like
the joker said! Even though this is a famous paradox, the Minute Physics video
kind of gives a partial answer answer (Click here to see).
I'll spare you the trouble An Immovable object = An
Unstoppable Force (a.k.a non acceleratable!)
This kinetic energy is then stored into the bonds that make it essentially make it tougher with every hit. There are limits to this but are not specified in the Marvel Universe.
If you are unfamiliar with how molecules are made here is
a short explanation, the bond formed between any two atoms is through either
the exchange of electrons (which most metals do) a.k.a "Ionic Bonds"
or by sharing electrons (which most non metals do) a.k.a "Covalent
Bonds".
Here is where it gets weird, in our world when any kind
of energy is supplied to atomic/molecular bonds they break off when they reach
a certain "Enthalpies" or Energy Levels. So in real life you would
have to either supply enough energy to break the bonds or have
the bonds dissipate energy in other ways like sound and
heat. Which exactly happens in the Avengers when Thor hits
Cap's shield leveling down an entire forest (Although this is
much much much more bigger if an actual Thor hammer hit and actual Vibranium
Shield, I am talking planetary scale destruction!).
A back of the envelope calculation says that
the shields temperature, depending upon the blow can rise from
nothing to Absolute HOT, just like absolute zero but much much more hotter!
Like 1.41 X 10^32 kelvin, at which point the laws of physics would
cease to exist. (Check out Vsauce's video Here!).
So to anyone holding this shield in hopes of saving
yourself, be warned you might be vapourized!
