So, I just got out of the theater from the movie and it was amazing! Although, I couldn't stop geeking out and my family told me to shut up several times. Not my fault that I get really invested in the universe and characters!

So I have this theory about the number 42. Maybe it has to do with the abilities since calcium has a radioactive isotope that has the atomic number of 42. It is a metal which would explain the electricity and the 'invisibility' is some sort of camouflage or protective shield that makes him feel invisible because it should not be making his clothes/suit invisible unless it expands to anything Miles is touching with his skin. If someone could tell me the comic book logic behind it, that would be great.
