Humanity’s Interstellar Exodus

July 31, 2014 — 12 Comments

evoraEarth’s days are numbered. Eventually, all scientist agree, she will die . . . and all life on the planet will perish.

Even if this doesn’t occur due to a catastrophic accident like a massive asteroid impact or an alien invasion, it is inevitable. Inevitable.

If nothing else interferes, scientists tell us earth will die in the death throes of its own star. In about 2.8 billion years, the sun will destroy all life here. Before the sun consumes its nuclear fuels and transforms into a “red giant,” it will have scorched the solar system.

It’s a disturbing thought. At least, it can be to those who place their hope in the future of humanity. Christians, in contrast, look forward to the promise of a new creation, a new heaven and a new earth, where even the harmony of the cosmos will be restored.

For those who believe that ultimate meaning can only be found in the continuing evolution of humanity, it is necessary to see an opportunity to continue the race. Until we evolve into pure mind and energy forms (right!) we need to find a place on hospitable worlds where we can survive, prosper and continue to advance.

So, if we assume it’s necessary for humanity to continue to exist, and our days here on earth are numbered, what are we to do?

The answer’s obvious. We must migrate to the stars. Baby steps are already being taken, with planning for our first colonies on Mars and our own moon. Many movies have explored establishing our presence in other solar systems. In fact, it’s become a trope of the scifi genre.

Some writers and directors envision a welcoming universe. Others populate it with hostile environments and competitors.

One of the most disturbing thoughts I have heard in the past few months was voiced by a scientist contemplating this subject. In essence, he said that our observation of nature shows that it is the predators (not their gentle prey) that must become smarter than the rest of the fauna to survive. The presumption being that it is the predator, not the grazer, that would evolve farthest and potentially venture into space.

I grew up influenced by the utopian images of Star Trek. Sure, there were Klingons and other threats out there, but there were also a large number of affable races that were eager to band together and share their knowledge and culture.

Star Trek went a step further. Even our one-time enemies (like the aforementioned Klingons, the Cardassians and the Ferengi) could become our allies. Well, there’s a precedent in that here on Earth (think post-war Germany and Japan). Still, it may be a tad naïve when it comes to interstellar swashbucklers.

Of course, all this presumes that we are no “alone” in the universe. By alone, we mean, the only sentient beings to populate the stars. (That’s figurative language, of course. No one lives on the stars themselves . . . that we know of.)

The prolific writer C.S. Lewis wrote a series of books about humanity’s first encounters with life beyond our planet. The Space Trilogy will be of interest to open-minded fans of science fiction, and to people who enjoy learning more about Lewis’ broad interests.

The first book in the series is called Out of the Silent Planet. In a 1939 letter, he explained to a correspondent one of his reasons for writing the book. [The quotation refers to Professor Weston, who is the novel’s nemesis. One of his goals is to usher in the age of human colonization beyond our own orbit.]

The letter [at the end of Out of the Silent Planet] is pure fiction and the “circumstances which put the book out of date” are merely the way of preparing for a sequel. But the danger of “Westonism” I meant to be real.

What set me about writing the book was the discovery that a pupil of mine took all that dream of interplanetary colonization quite seriously, and the realization that thousands of people in one way and another depend on some hope of perpetuating and improving the human race for the whole meaning of the universe—that a “scientific” hope of defeating death is a real rival to Christianity.

With this, we return to our initial thought. If we are looking to the stars for humanity’s hope, I’m afraid we will ultimately be disappointed.

I don’t know if there is mortal life beyond our planet. If there is, I can’t predict whether it would be friendly, or inimical to us.

Who knows whether we could even communicate? It’s a mystery for now. What isn’t a mystery, is whether or not we need to look beyond this tiny blue globe. After all, it is certain this world’s days are numbered.


Note: The alien at the top of the page is the Regent of the Evora species, a Federation protectorate. I used her image because of the curious marking on the crown of her head. It resembles a tattoo of a cross, but from the lines on the sides of her head I suspect they might all merely be varicose veins.

    I always thought Lewis’ thoughts on extraterrestrial life were quite on the mark. His primary one was the whole question is mute until aliens come down and tap us on the shoulder.

    His other idea was it might be a bad idea to desire contact with alien life. For one, if we were more advanced, then it would be certain we’d treat them the way humans on this planet have always treated “inferior” cultures and races. And if the aliens were more advanced than us and fallen as well, then we can imagine how they’d treat us.


    RE: “If we are looking to the stars for humanity’s hope, I’m afraid we will ultimately be disappointed.”

    In whatever genre Lewis wrote, he was a nonpareil in my eyes for this reason: he never let himself or the reader lose sight of the larger truths, the place where hope is located. I read Perelandra as a young wife and mother at a time when the future seemed very uncertain in more ways than one. That novel gave me hope, placed me in the context of something, Someone, larger than myself and those I loved, and gave me … how can I put it? …. steadiness.

    When I see Lewis one day, I look forward to thanking him for that, but I imagine he would say very simply, “Soli Deo Gloria.”


      It’s wonderful to hear how some of his individual works have ministered to people precisely when they needed to hear their words.

      Yes, I think everyone will be thanking each other in heaven, but all of that gratitude will rise like a sweet aroma to the Source of all that is good.


    Oh how I love Perelandra! It contains one of the most memorable and chilling scenes I’ve ever read (without giving too much away, the planet’s other visitor repeats Ransom’s name over and over and over.) Thanks for this post and the reminder of how much I have enjoyed the first two books of Lewis’ Space Trilogy. I think it’s time to venture into the third.


    Thanks for this interesting post. I’ll add these books to my ever growing list of ones worth giving a try. I say ever growing because right now there are more things that I want to do with my time than there are hours in the week to do them in :)


      If you like scifi, and you’re not antiChristian, you should enjoy the books. You don’t need to be a Christian to enjoy any of Lewis’ writings, of course, but if you have an animus towards Jesus and those who follow him, you’re likely to find many faults in books like this.


        Scifi, like any fiction genre, can be enjoyable. As to anti christian, definitely not. As to “being a Christian” that rather depends on your definition :)


      Always. Definitions are everything to effective communication. In the spirit of Lewis’ advocacy of “Mere Christianity,” I stand with those throughout history who have identified as Christian those who affirm the ecumenical creeds.
