I can think of several ways to gradually alter their orbits so they don’t hit us. Implementing those methods is neither easy nor quick. If there really are any seriously threatening objects out there, the sooner we find out, the sooner we can start building a solution.

Or we could wallow in ignorance until it’s too late.

Choose wisely.
