What would happen to the moon and Earth if the sun suddenly ceased to exist?

Well, if the sun decided to call it quits, Earth and the moon would be left in the cold, endless vacuum of space wondering where the hell all the light and heat went. Eventually, without the sun's gravitational pull to hold everything together, the planets would go careening off in all directions like a game of cosmic pinball. So, say your goodbyes now, because once the sun goes poof, we're all gonna go boing!
