Asteroids
The asteroid that just missed earth gave me an idea. What's more important than the survival of our planet? Well, if we can't save earth, why don't we spread our seeds? I think everytime an asteriod passs by we should send probes, rockets or whatever to attach itself to the asteroids. Implant them with a variety of organisms or cells or any biological substance that can survive the journey. Oh, not to forget cameras. Who knows, they may lead us to the ends of the universe. Ok not universe but it'd give us a chance to peep around. Plus, everyone loves a free ride. They could broadcast the camera footage onthe internet for the world to see.
Hopfully they won't hit earth making the whole experiment a waste.

Why does everything in space seem sphericle in shape? Is the universe itself sphericle?
