Comic book superheroes belong to a subset of the fantasy/ science fiction genre. The powers and abilities of these amazing beings are fun to speculate about, but are never terribly logical. Let's face it, if their abilities made sense, we'd all be sporting diy superpowers. Ironman's "wearable jet" isn't realistic (I want his power source, whatever it is) but it sure does make for some cool graphics and story lines. Nobody buys a comic book, after all, to watch someone in an erector-set exoskeleton manipulate a tennis ball. They want escapist action fare. And Superman's powers have a constantly evolving explanation. It used to be claimed that the gravity differential between Krypton and Earth provided his abilities. Then they switched to the difference between a red and yellow sun. Now it's alien physiology, I believe. At any rate, does it really matter? All good fantasy stories require suspension of disbelief. Go watch the movie, enjoy, then go back to the real world and actual physics. That's what I plan to do. C.
