One of these rocks is not like the other. One is a meteorite, and one is an asteroid, and we know that meteorites come from asteroids. So how come they look so different? The astroquarks discuss new research into ancient meteorites that shows how the tumultuous history of the asteroid belt is to blame. Plus charm quark Addie Dove points out that one rock is on the ground and one isn't, so there's a pretty big different right there. Strange quark Josh Colwell gets very strange with the sponsor message, and top quark Jim Cooney tells us that if you'd like to age about 1 second slower than everyone else you just have to move to the center of the Earth's core. In other words, just another episode of Walkabout the Galaxy.
