According to the astrophysicist, Neil deGrasse Tyson , the hammer is composed of neutron stars , one of the most densest material in the universe, and would weigh more than 3000 million elephants, or in other hand, somewhere around 5.4 billion pounds.

Beyond their exorbitant weight , physics professor at the University of Minn , Jim Kakalios, explains that the hammer would also be subject to Newton's First Law of Motion . The law says that an object at rest will remain at rest if no force will act on it . Therefore, when the hammer is in a surface , there is a downward force on it via the gravitational force between the mass of the hammer and the mass of earth (also known as gravitational weight), which causes it to stand still.

When someone tries to lift Thor's hammer , a large force is being exerted upward and still Mjolnir remains at rest . Science then assumed that the metal uru , that would be one of the fictitious components manufactured by Hammer Asgardians , works with a downward force that " cancels " the upward force if the person deserves not lift the Mjolnir.

But after watching the trailer for the new "The Avengers" sequel, and if the mjolnir weighs as much as it says, why it didn't turned Tony Stark (aka Iron Man) desk into dust!?
Unfortunately for that, science has not yet found an explanation.

Watch below the Avengers: Age of Ultron movie trailer and see if you agree with the theory:
