ABSTRACT

As far as we know ‘for certain‘, we are the only sentient species in the universe, on the only living planet. As life-forms ourselves, we naturally have an interest in perpetuating life. We know that our own solar system has a finite life-span. Indeed, this is the fate of all suns. We are about half-way through the life-span of our sun, and at some point, commonly put at about 5 billion years hence, our sun will run out of nuclear fuel, and go through a process of expansion, destruction of most of its planets, and then collapse and explode.

Thus, for the life that has evolved in this solar system to continue to grow and evolve, some way must ultimately be found to migrate to other suitable star systems before that point. Mars and all other potential human habitations in our solar system will be destroyed.
