The film is purely science fiction, but in promos the producers are making a big deal out of the fact that it was made with the help of some pretty reputable science-community sources. Namely, the rockstar physicist Brian Cox from Manchester, who was asked to take a fantastic, highly unlikely scenario and make it plausible.
“It was like: ‘the Sun is going to die in 50 years, think of something, will you?’” Cox says of the movies’ production team. And so he and other advisors at the Large Hadron Collider came up with the idea of using “Q Balls” (which scientists aren’t even sure exist), which could be nuclei of supersymmetric particles that devour matter, turning neutrons and protons into more supersymmetric particles. In the film, a Q Ball gets lodged in our sun and starts eating away. Physicists are sent into space on a ship called the Icarus II to throw a Manhattan-sized bomb into the star to kick start it back up.
