Heaven and Earth are about to collide.

Oceans rise. Cities fall. Hope survives. These are no longer just the taglines from Deep Impact the movie; they're also important considerations for Deep Impact the eccentric NASA project that will orchestrate a collision between a spacecraft and a comet on the 4th of July. Scientists are theorizing about the subsurface ices inside the comet, but I think it's time for us to start theorizing about what's inside the Impactor as it speeds toward its Independence Day execution. NASA has included a list of 625,000 names of people who signed up wanting to have their name destroyed by a comet (weird..). Has the Alberto Gonzales torture memo been included? The cube at Astor place? Leave your best idea for comet-bound object in the comments section, and the one that starts the whole world laughing will get a free Pale Ale (see below).

PS: You can watch the collision in real-time at 1:52am on July 4. Pick your favorite viewpoint.
