Astronomers have stumbled upon a tremendous hole in the universe. That's got them scratching their heads about what's just not there. The cosmic blank spot has no stray stars, no galaxies, no sucking black holes, not even mysterious dark matter. It is 1 billion light years across of nothing. That's an expanse of nearly 6 billion trillion miles of emptiness, a University of Minnesota team announced Thursday.

The things astronomers discover as they probe deeper into the universe -- orphaned baby stars, planet-devouring black holes -- paint a bleak picture of "out there." Heck, we might as well stay home.
