Scientists: Asteroid 1950 DA May Strike Earth Centuries from Now

"Why worry about an event that might happen some 35 generations into the future? Lead author Jon Giorgini of NASA's Jet Propulsion Laboratory explains he isn't trying to sound a warning bell.

"Instead, he wants to get researchers thinking about how to improve predictions of asteroid collisions - and how to prevent them."

If humans still exist 35 generations from now, I suspect we will have effectively taken control of our evolution and begun "disturbing the universe" in meaningful ways. Rogue space-rocks will be, at best, a minor nuisance.

It's the next century that really worries me, asteroids or no asteroids.
