Science Proves Luke Skywalker Should Have Died In The Tauntaun's Belly

It is one of the weirdest, wildest moments in Star Wars history. Han Solo picks up Luke Skywalker's lightsaber and slices open the belly of his dead tauntaun and stuffs Luke in to to warm him up and save his life.

But is this scene at all realistic? If you were freezing, would jumping inside the dead body of a giant animal really help you stay warm in this situation?

The article says yes but the counter arguments in the commentary section says otherwise and I happen to believe the "Skywalker would survive" case.

Enjoy geeks.
