Will the Great Attractor Destroy Us?
Somewhere, in the deepest reaches of the cosmos, far from the safe confines of our home galaxy, the Milky Way, lies a monster. Slowly, inevitably, it is pulling. Over the course of billions of years, it draws us and everything near us closer to it. The only force that acts over such immense distance scales and through cosmic periods of time is gravity, so whatever it is, it's massive and unrelenting. We call it the Great Attractor, and until recently, its true nature has been a complete mystery. Note that it's still a mystery, just not a complete one.
