Imagine a situation: Thor and Hulk in a spacecraft in near-Earth orbit, in conditions of unweight. Thor releases the hammer from his hand, which hangs in the air. Question: Will Hulk be able to use the hammer?
If so, then weak protection from NSD, techno-magic pumped. It is uninteresting.
But if not, then it turns out to be a very interesting object: hanging in space is a relatively unmovable object that cannot be moved. Here is the point of Archimedes!
What if I put a hammer in a box? Also not? What is the difference between a box and a spacecraft in which the hammer can move?
