Okay, Maximus, here are some further thoughts on whether we humans might be able to colonize another planet if we trash this one.  As I see it, there are several big questions that have to be answered successfully if we are ever to do this:

1.  Can we do it in time?  how much time do we need?  how much time do we have?

2.  Is there another planet in the universe where we could survive as humans?  if there is, can we find it?

3.  If we can find it, can we get there, set up house, and survive?

Asking the questions is the easy part.  But solving the problems they pose is daunting.  As you start to examine the obstacles that have to be overcome, it is tempting to think that the entire enterprise is so close to impossible that we might as well give up the idea altogether and stop wasting our time.  But humans being what we are, I doubt we will stop trying when there is even a sliver of hope that we might be able to do it.

I will talk about each of the challenges in my next three posts.  Tomorrow:  do we have enough time?
