More reasons to reach for beyond the skies. Altho' we are starting to get a handle on just how many bowling balls we're splaying skittles for, one thing that is especially chilling is those searching and tracking freely admit that, even if we track every object, there is still a good chance that something will come out of the blindspot caused by the sun with it's orbit changed just enough to smack it into us with almost no warning.
We desperately need a colony - 1000 people 'elsewhere' than on Earth would be 'all' the insurance policy we need. 500 people would do as a last ditch redoubt altho' there are more long-term problems gentically (if what I recall from my 1970's biology still holds true ).
