Science Project - Superman.

Well, my teacher told my class to do our science projects on anything related to science, so I decided to do the science project on Superman, because I know a lot about him. I am currently working on it, I have been for a while, it is due tomorrow and I don't think I have enough information, I have related all his super powers and weaknesses back to science, but besides that I cannot think of anything, can you people help me? What else can I include that is related to science and superman.

HELP!

Go back to Krypton. What could have made it explode? If Krypton was a planet orbiting a red sun, what would it's structure be like, it's gravity, how would that change it's landscape from Earth? Thigns like that. Perhaps that would help.
