The Great Cosmic Collision

I'm thinking of the sun.  It's only one tiny star among billions of other stars in one tiny galaxy, among billions of other galaxies.  Thinking outward into time, I know that in perhaps three billion years (give or take) our own Milky Way Galaxy will collide with its nearest neighbor, the Andromedia Galaxy.  Think about it!  Scientists have a very accurate picture of what it will look like, you want a peek?  I dare anyone to watch this and not be moved.  If you have dial-up it'll be slow but don't give up.  And if the movie stops midway, click play again.  Just look at this.  Science Bulletins | Astro |
