It is interesting superpowers down to cellular levels, but it always breaks up if you think too hard.
One thing that always amuses me to remember was Marlon Brando trying to convince Richard Donner that Kryptonians should be beings of light and pure energy, and not physical humanoids with five fingers and two feet. That here they take our form, that the physical world for them was an abstraction, just an 'energy world' would be an abstraction for us.
Sure, that thought would never saw the light of day. How could a director film abstractions? It would be like 2001 ending.
I always found this a more reasonable approach to superman-like superpowers, especially about someone who can fly. It has to be beyond our science and our common sense.
Still, it is fun to think about physical implications of superpowers.
