Hammer

The Marvel Cinematic Universe consists of many boring or uninteresting elements.  One of those is "Thor's Hammer" or Mjolnir.

A barely mentionable property of said device has to do with its mass or weight.  At least, that's how it appears.

Only an individual who is or isn't "worthy" may lift or wield it.  How the hammer can or can't "know the difference" is never explained.  It's a mystery.

We can only present a "present day" explanation for how such technology "works":

• Using "suggestion" "back-masked" in "noise", the hammer "suggests" any individual who needs or wants to lift it that:
• [You or they] are or not aren't [able or unable] to [lift or wield] [me or us] [by or through] [how or why] [they or you] [judge or jury] [yourself or others].
• Based on how an individual "deems" themselves they are or aren't able to lift or wield it.
• The hammer may or may not weigh any more than a typical item of its size.
• An individual may or may not choose to ever grip or touch it based on their own "worthiness".

Backward or "we all fall short of our own convictions or ideals".
