Meet the Scientific Consultant for the New "Thor" Movie

| Wed Nov. 6, 2013 3:10 PM EST

Yes, Thor: The Dark World—a new film about a Norse-myth-inspired superhero traveling through space and fighting elves with a hammer—had scientific consultants working on it. One of them was Sean Carroll, a theoretical physicist at the California Institute of Technology.

"Marvel is very, very interested, with every movie they make, in trying to meet with scientists," Carroll says. "With real-world sciences and the comic-book universe, they just try to make it all hang together."

Carroll is a 47-year-old cosmologist who researches in the fields of particle physics and general relativity, and wrote a book on cosmology and time called From Eternity to Here. He was an informal consultant on both Thor: The Dark World and Thor, its 2011 predecessor. He met with the writers, directors, and production staff to help massage the scientific details.
