Who

On another Rapture site,

In December 2012 the Sun will reach the center of the Milky Way Galaxy, as the Mayans predicted, with all the planets lined up in their orbits behind it, like little chicks behind their mother. Some scientists believe this will amplify the Sun’s gravitational pull on Earth causing increased instability in its inner core. They say the increased gravitational pull combined with increased radiation from the twin polar reversals will heat the Earth’s molten core and cause it to spin faster. This could result in anything from more frequent and more powerful earthquakes to volcanic eruptions, great tsunamis and even displacement of the Earth’s crust.

The Doctor will save us.
Though they are making it sound rather simpler by omitting to mention the immense black hole we'll probably find there. Also Daleks, I wouldn't be at all surprised.
Though I suppose there's an actual point there; today even religious maniacs have no social vocabulary to express their eschatology other than that provided by science fiction thrillers. The Hand of God can't just come down from the sky and punch someone; there has to be an increased gravitational pull that makes them fall over. And yet at the end of this process The Hand (and all the other bits) of the Son of God does apparently just come down from the sky and biff people, so why not at the start, too? It bespokes a certain lack of confidence in the direct action of the deity. If god can act through increased radiation rather than killing firstborn, why do they have a problem with evolution?
Of course, it's always possible that they'll catch us between Doctors - I gather that the new one doesn't come on till next year. That would be truly frightening.
