WCCO-TV’s Video Library now features an interview with U of M Professor James Kakalios, author of “The Physics of Superheroes.” I talked about his book in my 2005 FallCon article.

His book is thick, but a great read and it’s clear he knows his stuff. He has a mindboggling explanation as to how Superman could come from a Krypton dense enough that he could possess superpowers upon reaching Earth. (The only other explanation would be that Krypton was larger than Jupiter.)
