you know Bonehilda is a badass that she can go two steps beyond death not only being able to be a skeleton but to be a skeleton ghost.
what even.
In The Avengers and the comics, Thor's main mode of transportation is spinning and then throwing the hammer, and hanging on for dear physics. With the help of Neil deGrasse Tyson, there are numbers and assumptions we can make to see just how demigodly you would have to be to wield such a power. With enough strength to literally toss billions of pounds around, you would be "worthy" indeed.

The kinetic energy alone is out-of-this-world huge. Throwing the hammer at 100 mph (45 m/s) gives it 688,500,000,000,000,000 Joules of energy. That is almost three times the yield of the largest nuclear bomb ever exploded, Tsar Bomba, which shook the Earth with an equivalent of 57 megatons of TNT. Needless to say, with this kind of energy, Tony Stark should have asked Thor to simply throw his hammer at the alien ship at the end of The Avengers and watched the fireworks.
