On the
4th of July, a copper object will be dropped into a comet named
Tempel I, no less, to see what happens. I'm as curious as the next
guy to see what happens. That said, picture this:
Scenario
1: Nothing happens.
Scenario
2: A massive shock wave results.
Scenario
3: Little green men come running out of the crater, shaking their
fists and swearing, wondering what's happened.
Scenario
4: A perfectly formed fireworks flag shoots from the crater, accompanied
by sound effects of an appropriate national anthem.
