Did Avengers get the science right? Copernicus (aka Andy Howell, astrophysicist at UC Sta. Barbara) brings in a review of the Avengers from a scientist’s point of view. Avengers fares pretty good, actually, compared to other films (unlike his review of Star Trek, in which he points out several major mistakes no self-respecting science fiction movie with time travel and starships should make).
You can tell he’s a physicist, because he hardly covers the possibility of the Hulk (he just accepts it, on faith, like a priest) or of Captain America (He says it’s not interesting. Enhancing a human being is not as interesting as stars and black holes?).
He also doesn’t cover the SHIELD Helicarrier’s cloaking device. In James Bond’s “Tomorrow Never Dies” (who stole the idea from Masamune Shirow’s “Ghost in a Shell”, they use video cameras to project on an object what is behind it, theoretically rendering it invisible, but that doesn’t work well on moving objects or objects as large as an aircraft carrier. There are other possibilities I found in Wikipedia.
That still leaves a lot to Geek Out on, like the Cosmic Cube, Thor’s lightning striking Iron Man (Why should Stark be surprised? It’s a Faraday Cage!) and how much energy would it take to lift the Helicarrier?
Here are Copernicus’s reviews on the science of the Avengers:
and as a bonus, Copernicus also links to io9’s video on the possibilities of creating superheroes (the portion regarding genetics starts at 5:43 in the video):
