Diving into the ring of darkness beyond things easily answerable, asking ‘Why?’ questions is what make humans awesome

Imagine a planet on the far side of the galaxy. We will never interact with it. We will never see it. What happens there is irrelevant to us, now and for the conceivable future. What would you hope this planet is like?

Would you hope that it’s a sterile rock, as barren as our Moon? Or would you hope it has life? I think, like me, you’ll hope it has life. Life has value. Other things being equal, a planet with life is better than a planet without. I won’t argue for this. I take it as a starting point, an assumption. I invite you to join me in feeling this way or at least to consider for the sake of argument what might follow from feeling this way. Life – even simple, nonconscious, microbial life – has some intrinsic value, value for its own sake. The Universe is richer for containing it.

What kind of life might we hope for on behalf of this distant planet, if we are, so to speak, benevolently imagining it into existence? Do we hope for only microbial life and nothing more complex, nothing multicellular? Or do we hope for complex life, with the alien analogue of lush rainforests and teeming coral reefs, rich ecosystems with ferns and moss and kelp, eels and ant hives, parakeets and spiders, squid and tumbleweeds and hermaphroditic snails and mushroom colonies joined at the root – or rather, not to duplicate Earth too closely, life forms as diverse and wondrous as these, but in a distinct alien style? Again, I think you will join me in hoping for diverse, thriving complexity.
