Sam, the aforementioned talking rock from outer space, was moving very quickly through space, on a trajectory that would end abruptly in Davis’s backyard. When Davis picked him up out of reasonably sized crater in his backyard, Sam would be a lot smaller than he had been when he had begun his mad streak across the universe.
Why would Sam (a generally easygoing piece of space debris) be shooting towards Earth at such a pace, when he had never left the Oort cloud in his entire existence?
It was because of the encroachment of Nothingness that Sam was in such a hurry.
Nothingness had had enough. Nothingness had become militant. It had bought a camouflage jacket. It grew an afro. It burned its bra. Nothingness was pissed, and it wanted its stuff back. It had been reabsorbing somethingness back into nothingness for millennia now, and it had finally arrived at our Universe. By this point, it had gotten quite efficient at nihilization, and it scared the minerals out of Sam.
He had to find someone to tell about this. He didn’t know who he would tell. There was always someone to tell when things went bad, right? Somebody could always get things under control. Sam was going to find someone. He was just a big rock (soon to become much smaller). What could he do?
