Sunshine: could the Sun go dark?

I don’t know how plausible is the scenario that some kind of unusual matter could “infect” the Sun and turn off its nuclear furnace, but that’s the premise underneath Danny Boyle’s latest DNA film / UK Film Council psychological sci-fi “thriller” Sunshine. (I have read of some wild speculations of how physics experiments could go so wrong.) On the closed world of the spaceships, we see the crews deal with the morality of "playing God" -- drawing straws on their own lives and on civilization back home.

Of course, we don’t see how people got by on earth during the seven bad years of reduced sunlight. We see more of that in a 1998 TV film from ABC called Ice, directed by Jean de Segonzac (from Trimark, which used to be another indie film company). It starts with a sudden cold snap in May, where it freezes in LA and snows in Washington and St. Louis, and where meteorologists sound nonchalant. But soon the Hollywood sign itself is covered with snow, and bedlam breaks out. The explanation has something to do with infection by sunspots. This film was much less convincing, however, than “The Day After Tomorrow” (where the freeze happens because of the loss of the underwater Gulf Stream, with a resulting superstorm).

Conventional astronomy, or course, says that the Sun will swell up to a red giant in a few billion years, and then shrink to a white dwarf. We have to get off the planet by then.

Don’t mix the Sunshine film up with an earlier film of the same name from 1999 directed by Istvan Sazbo, about an Austrian family that undergoes true catastrophe under Hitler and then Communism.

By the way, the new Sunshine comes from Fox Searchlight Pictures, and the company trademark eases into the film by zeroing in on the Sun on the horizon in the trademark.

Update: Sept. 15, 2007
