Time to recalculate? Thor's hammer may be a featherweight





The lightweight hammer doesn't explain his bulging muscles.

Astrophysicist Neil deGrasse Tyson brought Thor's hammer Mjolnir into the geek spotlight recently by running some calculations on its weight. He shared his findings over Twitter, saying:




If Thor's hammer is made of neutron-star matter, implied by legend, then it weighs as much as a herd of 300-billion elephants

It's a good thing he said "if," as it's starting to look like he might be wrong. Suveen Mathaudhu is a program manager in the materials science division of the US Army Research Office. He pointed out to The Abstract of North Carolina State University that Thor's hammer is actually made from Uru, a fictional metal found in the faraway realm of Asgard.




"The critical mistake Tyson makes is thinking that Mjolnir was forged of the core of a dying star, when it was actually forged in the core of a dying star," Mathaudhu said. He shared some calculations of his own.
