If one were to truly believe that it were going to happen, it shouldn't be hard to generate a list of dates on which it could happen, given some mighty blow to the Earth. If one wanted to be more specific about the orbits in which the other planets wind up, the list of dates could be narrowed even further. I'd love to see that list... not that I'm going to put any work into it  Perhaps we can persuade loser to train in astronomy. |
Good luck with getting him to learn anything

Btw, from what I've heard, our Sun is approximately middle-aged; it's been around or 4.5 billion years, and it's got about five billion to go... so how does that figure with your estimate of the endurance of the human race?! :)
I'll be very disappointed if we don't ditch this planet until the Sun forces us to. That's a looong time to spend "getting it together".

Oh 5 billion years, that changes everything
. I give our species maybe 2 million years, and that is my most liberal estimate. There is a very good chance we wont last another 10 before we destroy ourselves. Hell we might not be around next week.
But I agree, we should put some effort into getting off this rock and onto a new one well before conditions necessitate it.
