Milky Way on collision course

It’s not as if the credit crunch and the multi-trillion dollar black hole in the middle of the world’s economies isn’t enough.  Now scientists have just announced that

  • the solar system is orbiting the centre of the Milky Way at 600,000 mph, 20% faster than previous estimates
  • the mass of the Milky Way is about twice as big as scientists thought
  • so that the liklihood of the Milky Way colliding with another galaxy is much greater and will probably happen much sooner than scientists have been estimating.

On the other hand, a collision is not likely to happen for several billion years at the earliest.

So there’s probably still time for breakfast tomorrow.
