questionsdo you know much about mjölnir?


He does call out some movies on scientific inaccuracies.


i'm not familiar with the details of mjolnir's forging. tyson assumes it's made of neutron star matter; where does this assumption come from? in the comics, captain america is able to lift it, so the comic book weight seems incompatible with the idea that the hammer is physically that heavy.

no1 no1

Thor is all sorts of magic. Mjölnir's weight only comes into play when it is being swung about--at least that's the made up rule inside my brain.


I was always a DC man myself, and what little dabbling I do in the world of Marvel hasn't been centered around Thor, but my understanding was always the hammer can't be picked up by others due to some sort of magic, not that it was super heavy. Considering others than Thor have indeed picked up the hammer (either the hammer allowed them to, Thor allowed them to, or some weird, whatever there's no consistency in comics anyway). Back to the point, I've never seen anything to indicate that the hammer weighs more than some planets. In fact, doesn't it have writing on the side saying if wielded by someone worthy, that person gains Thor's power?


If I recall correctly, the deal is that only a hero can lift Mjolnir. That's why Thor was unable to lift it in the Thor movie when he was stuffed full of vainglorious pride. He had to find some humility and wield it for honorable reasons to be able to lift it from where Odin tossed it. It's similar to the story of the sword and the stone. It's not a test of physical might, it's a test spiritual strength. From time to time in the comics they used this as a statement on who was and was not a true hero. Mother Theresa could lift Mjolnir, but Michael Vick could not.

I always liked Thor, because he's hot, but didn't follow his comics all that closely. When I was a kid I liked Namor and Kazar, as a young adult X-Men was my main interest.


Mjölnir's weight is relative to the purity of your intentions. If you are a hero with good intentions - it's effortless. If you are a villain, it gains 'weight' in proportion to your negative intent, making it impossible to pick up.

Magic, son. Magic.


Yes, magic, not science like King Arthur's sword in the stone. And it's not getting heavier, i.e. an increase in mass, because if it got heavier, it would start to fall through the Earth's crust, mantle, etc and eventually get to the core weighing quadrillions. And this is just Marvel canon.

I don't remember anything about no one unworthy being unable wield it in the normal Norse mythology. Thor, however, did need the girdle of strength and gloves to wield the hammer.


To lift the hamer was one thing, it took strength of spirit, good intentions, all thats been said. However, to weild the hammer (actually use it adaquately as a fighting weapon) in all it's glory did require Thor's godlike strength. Captain America could lift it maybe swing it in battle but he would have never been proficient with it.


Magic aside, 4 quadrillion sounds like a lot, but there is a reason why when talking about numbers the word "astronomical" means really big.

weight of Mjolnir:
4000000000000000 lbs
weight of Mount Everest:
6705160000000000 lbs
weight of the moon:
162040000000000000000000 lbs

4 quadrillion is a rounding error when it comes to celestial masses. So while things like individuals or planes lifting it would be concerning, the earth would hardly notice.


@scmtim: Except that if it weighed that much it seems like it would sink into any kind of softer ground quite deeply, as it doesn't have the "footprint" of Mt. Everest to distribute its weight. Snowshoes vs feet. But I don't recall anything in the Marvel comics regarding it being astronomically heavy.


@scmtim: If it's about weight, there's also a huge difference in terms of density as well. Mt. Everest is a huge as well as the moon. Mjolnir is a large hammer so it's immensely dense and would drill through the earth.


Yes there are factors relating to density, but the original question about it affecting earth's rotation is more related to mass. I was trying to give some context as to how big something has to be to affect earth's rotation.


There was a great line in the Thor movie, where Thor explains to Jane Foster that in regards to magic and science, he comes from a place where they are one and the same. That itself is a reference to an old saying, that any science or technology sufficiently advanced would appear to be magic to a more primitive culture.

So, in short, the hammer behaves according to the rules of a "magical" science that humans are still too primitive to fully understand. :-)


Here's Thor's quote:
"Your ancestors called it magic, but you call it science. I come from a land where they are one and the same."

And later, Jane points out,
"Well, 'Magic's just science we don't understand yet.' Arthur C. Clarke."


i know the 3rd letter in his name resembles a woman's face in a short film i viewed last night


@pinchecat: I assume you're referring to the O-umlaut, in which case this resembles an expression as opposed to someone's face... (Mjölnir is not a he/she)
