"I am the least scientific person you'll ever know." Stan 'The Man' Lee admits that he doesn't know very much about science, but that certainly didn't stop him when he created classic Marvel characters with science-based origins such as Spider-Man or The Hulk. Stan lee says he was trying to be "scientific with our characters." Stan Lee says that with Superman you wonder how he is flying. He says
"When Superman flies, he has no visible means of locomotion. You might wonder 'how is he flying?'" Stan Lee then compares Thor's flight to Superman's flight.
"He has that hammer, I had him swing it around as fast as a propeller. Then he lets go! Now, it's attached to his wrist. So when the hammer goes shooting off into space, it takes him with it. That's how he flies. Incontrovertible Scientific Fact! And that's the difference between us and the competition." You can watch the entire interview in the video embedded below!
