Can Superman break Thor’s Hammer?

According to Marvel, Thor’s hammer is forged inside a star’s core, with a star’s core, also with an Asgardian metal Uru and several enchantments. When the making was done, it destroyed the star itself.

What if Thor went up against superman? Can Superman destroy Thor’s hammer- his only source of power- the legendary Mjolnir? Or will Thor beat the hell out of Superman with his hammer which only the worthy can yield? 

Let’s see! Say Thor’s hammer is made from the most dense object known to exist in the universe, the core of a dying star, not just any star but a star powerful enough to cause a supernova and finally due to its own incredible gravitational field, collapse into what scientists called a “neutron star”.


Its density gets even more intense as we go deeper. At the very core it can be as dense as 8 x 10 ^ (17) Kg/ m^3. To compare, the densest material on earth is osmium and its density is only 22.59 x 10^ (3) Kg/m^3. 

We calculated the volume of Thor’s hammer according to marvel comics and it is about 9.451 x 10^ (-3) m^3.  Therefore it would weigh 7.56 x 10^ (15) Kg. 

i.e. 7560 Giga Tonnes.

Here a quick calculation (height Chris Hemsworth is 191 cm and time taken =3.82 secs) shows that Thor at his best delivers a hammer strike at a velocity of 2.162 m/sec.

With that speed, the energy of his hammer while hitting superman will be 1.767 x 10^ (16) J, about 280 atomic bombs that was dropped on Hiroshima on august 6, 1945. 

Superman is not going down without a fight either. 

Out of all things he does in comics, one thing that makes him incredible is going at the speed of light and turning back time. But we don’t want to turn back time, we want the fight so say he delivers a flying punch toward Thor’s hammer at a speed of 99.9999% the speed of light.

Some quick calculations (Henry cavil weight =92 kg and relativistic mechanics), his impact energy will be 5.8548 x 10^ (21) J, that is 3.3 x 10^5 times more than that of Thor’s hammer.

However, will he be able to really break his hammer?

When Superman’s fist and Thor’s hammer collide, the temperature around them would rise to an insane 2.82698 x 10^ (44) Kelvins, nearly 2 x 10^ (37) times hotter than our suns core. It will create a microscopic black hole of radius 9.64 x 10^ (-23) m and finally, with particle beams having energy of order 6 GeV and their impact energy being 3.654 x 10^ (31) GeV, they will literally knock the atoms out of everything around them. Everything around them will get liquefied at an atomic level turning into quark-gluon plasma, the very thing that formed right after Big Bang.

So, after the dust or in this case super-hot plasma settles, Thor will be seen crying and his hammer completely disintegrated but there will be literally nothing around not even atoms, to see him do so.
