Cosmology: A memo from the End of All Things Is at Hand Department

We are advised as follows at New Scientist, in "Dark galaxy crashing into the Milky Way" (22 November 2009):

THE Milky Way's neighbourhood may be teeming with invisible galaxies, one of which appears to be crashing into our own.

In 2008, a cloud of hydrogen with a mass then estimated at about 1 million suns was found to be colliding with our galaxy. Now it appears the object is massive enough to be a galaxy itself.

Called Smith's cloud, it has managed to avoid disintegrating during its smash-up with our own, much bigger galaxy. What's more, its trajectory suggests it punched through the disc of our galaxy once before, about 70 million years ago.

I can't wait till the movie comes out, and I also want to collect the DVD.

Three new Uncommon Descent contests: Lots of fun for physics buffs

Win a free Privileged Planet DVD, courtesy the producers, for the best post answering any of the following questions:

Uncommon Descent Contest Question 13: The Large Hadron Collider is back up and running, but why?

Nine billion dollars and 15 years later, what is the Large Hadron Collider likely to tell us that is worth the cost and trouble?

Uncommon Descent Contest Question 14: Is backwards or forwards time travel really possible?

Two physicists have suggested that Hadron's woes are due to particles travelling back in time. Their theory has been received with the amusement one might expect, but it raises an interesting question, one that is a staple of sci-fi literature - is forward or backward time travel possible, even for particles?

Uncommon Descent Contest Question 15: Can Darwinism - or any evolution theory - help us predict life on other planets?

At Britain's Telegraph (November 04, 2009), Tom Chivers advises that "Darwinian evolutionary theory will help find alien life, says Nasa scientist."

Here are the contest rules, not many. Winners receive a certificate verifying their win as well as the prize. Winners must provide me with a valid postal address, though it need not be theirs. A winner's name is never added to a mailing list. Have fun, and enter as many as you like.
