Science explains why Thor’s hammer cannot be lifted

If you’ve ever seen a movie in the “Thor” franchise or have seen “The Avengers”, you’ve probably wondered why no character besides Thor can lift the superhero’s magical hammer Mjolnir. Incredibly, there is a supposed scientific explanation for this.

According to astrophysicist and doctor Neil deGrasse Tyson, if the hammer was composed of star nutrons, the densest material in the universe outside a black hole, it would weigh more than 3 billion elephants, that is, something around 5, 4 trillion kg.

In addition to its exorbitant weight, the professor of physics at the University of Minnesotta, Jim Kakalios, explains that the hammer would also be subject to Newton’s First Law of Motion. The law says an object at rest will remain at rest if there is no force acting on it. Thus, when the hammer is on a surface, there is a descending force on it by means of the gravitational force between the mass of the hammer and the mass of the Earth (also known as “gravitational weight”), which makes it immobile.

When someone tries to lift Thor’s hammer, great force is being exerted upwards and even then Mjolnir remains at rest. What science supposes is that uru metal, which would be one of the fictitious components of the hammer manufactured by the Asgardians, works with a downward force that “cancels” the upward force if the person does not merit to lift the Mjolnir.

But after all, if he weighs so much, how could he not break Tony Stark’s table, Iron Man, in the new trailer for the “The Avengers” sequel? That unfortunately science has not yet found an explanation. Check out the trailer below and see if you agree with the theory:
