“The Crystal Spheres” by David Brin was first published in Analog, January 1984. You can read it at Lightspeed Magazine or can listen to it at StarShipSofa. It won the Hugo award in 1985 and won the Analog reader poll for 1984 short stories.

Literary short stories are generally small in scope, covering brief slices of time, using few characters, placed in limited settings, which make an emotional impact from a personal insight. This is my preferred form for a short story, even for science fiction. However, this doesn’t keep science fiction writers from spanning galaxies over eons featuring multiple intelligence species all in under 7,500 words. I loved these epic sci-fi stories when I was young. They had intellectual emotional impact if that makes any sense. Generally, I prefer small personal short stories in my old age, but I still admire the universe spanning imagination displayed in stories like “The Crystal Spheres.”

But something has changed in me as I’ve gotten older.

“The Crystal Spheres” breaks the cardinal rule of fiction writing classes, show don’t tell, but it proves rules can be broken — sometimes. I must wonder if Brin had used 350,000 words and told this story in a 1,000-page epic called The Crystal Spheres, if the sense of wonder would have been any greater? Could Olaf Stapledon have condensed The Last and First Men and Star Maker down to short stories and had them succeed just as well? David Brin does a lot with this short story.

“The Crystal Spheres” answers the question the Fermi Paradox asks: Where is everyone? It borrows an idea from the ancient Greeks, placing around every star a crystal sphere that keeps visitors out. Brin doesn’t go into whether these protective barriers are natural, or God made, or a product of intelligent design, but the end results is it keeps one intelligent space faring species from colonizing the universe like a plague.

This reminds me of the novels Spin by Robert Charles Wilson and Quarantine by Greg Egan, and to a lesser degree, the novel Out of a Silent Planet by C. S. Lewis, but for an odder reason. I read Spin first, and I marveled at the time that Wilson had produced a unique science fictional idea. But evidently, there is a tiny sub-genre of science fiction stories about barriers around the Earth or the solar system. I need to check into its history and look for other examples.

“The Crystal Spheres” evokes both the theological and the teleological. It reminds me of the Omega Point philosophized by Pierre Teilhard de Chardin. Brin thrills his reader with vast theories.

Although “The Crystal Spheres” isn’t a very satisfying short story on the personal insight level, its big fun alluding to many science-fictional concepts. Set in the future after humans have developed star travel, cold sleep, and immortality, it describes how humanity has become depressed because we’re alone in the universe. The story begins when a recently reawaked Joshua learns of a new discovery.

But to put that discovery into context Brin needs to set up a backstory. When humans sent out its first interstellar ship it crashed into an invisible sphere that shattered and created centuries of comets raining down on Earth, nearly wiping us out. Bummer. After things settle down, we start sending out starships again, but they keep crashing into spheres around other solar systems. They don’t break the spheres but do destroy themselves. Eventually, we learn how to avoid crashing into spheres and discover a few inhabited planets, mostly by hive-like beings. When we do discover races like us, we can’t communicate with them. We can listen to their broadcasts which can penetrate out the crystal spheres, but we can’t communicate into the spheres to say “Howdy.”

This throws humanity into a deep depression and most people go into hibernation hoping to wake up one day after we find planets we can visit. The story begins with Joshua learning there’s a solar system with a shattered crystal sphere and several possible planets orbiting that star.

It’s in another galaxy. Joshua and friends go there taking hundreds of years, using four diverse types of faster-than-light travel. When they arrive, they discover an abandoned civilization. I love science fiction about abandoned alien civilizations. At first Joshua and friends don’t know if these aliens have died off, committed species suicide, or just left for parts unknown.

Should I tell you everything? I’ve already told you a lot. I never know how much to give away. I want to discuss stories as if you’ve read them too, but I must assume that most of you haven’t read the story so I should keep from spoiling it. But how much should I tell to entice you into reading the story?

Let’s just talk about what I’ve already revealed. The idea of crystal spheres is a neat way to explain the Fermi paradox. Isaac Asimov even suggests this idea came about at Worldcon with writers suggesting ideas for a story, but he doesn’t specifically say David Brin was in that group.

Brin doesn’t give us any hard science speculation why the crystal spheres would be there, or how they work. It states that physical objects can’t penetrate them from the outside. But we know of extrasolar objects visiting the solar system. But was Oumuamua the first one we detected? Maybe when Brin wrote the story in 1984, no such visitor had been discovered. Or maybe only objects with intelligent beings in them can’t penetrate the spheres? And what about random bodies within the system? Why couldn’t some rock leaving the solar system have broken the crystal sphere long before the first spaceship?

See, that’s the fun thing about science fiction, it makes you question the story. Challenging questions. Sense of wonder questions. And in this case, are the crystal spheres naturally made, or from intelligent design? Now that takes us into some fun speculation. In Quarantine Greg Egan came out with a wonderful idea of why humans are locked out from the rest of the galaxy. I won’t give the answer because that would spoil the whole novel.

“The Crystal Spheres” is the kind of science fiction story that makes us think big, gigantically big. I loved that kind of science fiction when I was young. And reading “The Crystal Spheres” conjured that exciting old feeling. But my older wiser self, is more cynical. All those big sci-fi ideas are just childish fantasies. I have serious doubts we’ll ever make it to Mars, and believe interstellar travel is next to impossible. We can’t even save ourselves from self-destruction, so why imagine such exciting futures?

We face real barriers that keep us from colonizing the planets and traveling to the stars. But they are all within us. Our greed, our xenophobia, our petty resentments, our violent nature, our cancerous consumption of natural resources, and the list goes on and on. Our human nature is the crystal sphere that keeps us here.

I should stop reading science fiction, but I have a life-long addiction I can’t throw off. However, the older I get, the more acutely I recognize my childhood hopes about the future are just fantasies. I now crave realistic science fiction that deals with possible futures. Unfortunately, science fiction is written to sell to young people, and realistic science fiction is too depressing for them.

I got a big kick out of reading “The Crystal Spheres” because it encapsulated so many science fiction fantasies that I once loved. It’s still a wonderful story. But now that I’m old, it has a bittersweet twinge to it.

“The Crystal Spheres” reminds me of one last thing, the famous speech Marlon Brando makes in On the Waterfront, where he says, “You don’t understand! I coulda had class. I coulda been a contender. I coulda been somebody instead of a bum, which is what I am.” It’s sad that humanity won’t become what Brin and science fiction imagines.
