My question was closed as a duplicate. A commenter had linked the supposed answer, but that has since been removed. I had clearly stated that the other question did not answer my question.
Why was mine closed?
I voted to closed it as a dupe because the question that you're asking (which basically boils down to "What does the weight of Mjölnir feel like to those who're wielding it" is largely a duplicate of another question that is extremely similar (How much would Thor's hammer (Mjolnir) weigh?).
While they do focus on slightly different aspects of Mjölnir's weight, that is to say, its absolute weight versus its subjective weight, I think we can be reasonably certain that if a canonical answer was found to one of the questions ("in comic x, it's stated that Asgardian magic makes Mjölnir feel very light") it would certainly be copied/pasted to the other question almost immediately. That in itself seems a pretty clear benchmark that the two questions are basically duplicates of each other.
On top of that, the other question already has answers that address its absolute weight so unless you can express some reason to assume that the subjective weight is different, there's really no good reason to have a second question about it.
