Microstory 2621: We’ll Build That Bridge When We Come to It, and We’ll Do it in Style

Generated by Google Flow text-to-video AI software, powered by Veo 3.1
August 26, 2526. The cataclysm has escalated. The ring fault surrounding the southern pole has torn open. Rivers of lava flow through the chasms, threatening to incinerate any who would fall to their deaths below. People are cut off from each other. Some successfully made it across before the mountains pulled away from each other, or already lived in the safe zone. Others could not make it in time. Soon, the land beneath their feet will turn to soup, or some other hazard will end their lives. Something must be done to bring these people back together. A bridge must be built. No one has ever constructed anything like this before, and certainly not at scale, but they are not wholly unprepared. The southern polar region is more mountainous than the north. That is the primary reason why it has fewer domes at this point, and why it is less populated. It is more difficult to travel between domes, and traditional forms of engineering are both tedious and slow. That is why they have been experimenting with new forms of construction, including the fast-woven graphene lattice.
Instead of laying blocks of material on one end, and slowly adding farther and farther towards the other side, drones fly clear across the gap. Fewer refugees are seeking shelter in the southern pole. An entire quarter of the Terminator Line is even more mountainous than the cap. And one advantage they have compared to the north is a newly built dome that is recently sealed, presently uninhabited, and fully available for temporary housing. So instead of dealing with an untenable onslaught of people, the leadership was able to dedicate resources to researching the threats. They realized that the ground was about to break, and began to plan for that as an eventuality. They still have to hurry, but this will work, as long as they’re careful.
They chose a spot where the two edges of the chasm are particularly close together. It’s not quite in the center of the Terminator Line, but they have sent volunteers in both directions in parallel to the chasm, on the dangerous side, to direct refugees to the right spot to cross. They have been gathering in an emergency pressurized inflatable habitat, but it’s quickly reaching capacity, so it’s time to make this happen. Timing is everything.
The southern pole is a little different than the rest of the planet. It’s run by an advisory-administrative government. There are two delegator boards, which come to decisions independently, and compare notes before making a joint decision, which they then delegate to the administrators. Each delegation includes a skeptic. It’s unfair to call them uneducated, but they are definitely meant to be out-of-the-box thinkers who are meant to question everything that they’re told. If you say left, they say right. If you say right, they say wrong. If you say wrong, they say wrung. Their job is to fight you, even when you start agreeing with them. It’s the devil’s advocate for the secular world. That’s what Thadeus Hogan’s role is, and he was here to make sure that what they were doing made sense. He’s done that, so now he’s mostly just here to watch.
Thadeus stands on the edge of the cliff. His consciousness is backed-up, both on the ground, and in orbit, but he’s tethered to a safety anchor in case he slips over the edge, and doesn’t want to waste time in a respawn pod.
“Ready!” the ordnance foreman cries from the perch. “Ready!” he repeats. “Fire!”
The artillery engineers activate the railguns. The cryogenic warheads soar through the air, arch over the chasm, and then plummet into the depths.
“Can I get closer?” Thadeus asks. When his guide nods, he leans over. The bombs crash into the toxic lava below. He can’t actually see it, but he sees the change. The thermal updrafts change from a sickly reddish color to gray. It just looks like steam.
“Why did we do that again?”
“We just froze the topmost layer of that lava,” his guide explains again. She knows he’s like this. Asking the same question multiple times is his duty, because if your answer changes, how can you be confident in it? “The fumes were chaotic and unpredictable, and just too much for the drones to handle. They were designed to fly in the Proxima Doma’s thin atmosphere, but to make that work, they’re slow. By switching from fumes to vapor, they fly through much more manageable paths. They surf the air, and safely find purchase on the other side.”
As the ordnance foreman sits back down, the head drone operator stands to take his place. “Prepare the drones!” she orders. “You have two minutes!” This is just in case something has gone wrong. They are a well-oiled machine, and the drones have been ready for hours. They had to wait to begin constructing the bridge to make sure the ground was stable enough. There is no point in building a bridge if the gap is going to widen another kilometer by the time everyone manages to cross it. He’s keeping one eye on his launchers, and the other on the barometric technician.
The technician is tracking the shifting composition of the air, and waiting for that perfect moment. He lifts his hand in the air. The head drone operator takes one last look at the launchers, but then focuses right on the tech. “Hold! Hold!” No reason he can’t have a little fun with it. This is a momentous occasion. Finally, he slams his hand down.
“Launch!” the head drone operator orders.
The drones fire into the unprecedentedly thick atmosphere. Thadeus loses direct eyesight of them too, but watches their progress through augmented reality. And he can still see the graphene scaffolding that the drones are pulling, spindling out like a silkworm’s silk. The drones are flying in pretty close tandem, but the pressure gradient isn’t perfectly smooth, so some lose attitude, and have to regain formation. Once they’re on the other side, they drop anchor, slamming hard into the ground, and digging in. Volunteers on the other side drive over in their rovers, and lower their suspension into hunker mode to provide extra support. It’s not sophisticated, but every kilogram helps.
“Launch the weavers!” the head drone operator orders now. The smaller drones fly along the skeleton lines. They distribute themselves along them, and begin wrapping the webbing around, over the gaps between them, and around each other’s lines. Over and under, over and under. They build tensile strength in perfect synchrony, and what results looks like a fully stable, strong, and lifesaving bridge.
The convoy master is on the perch now, having ordered the test rovers to the end of the bridge. The drones have finished their jobs, and it’s time to make sure the bridge will hold, and not kill anyone who tries to drive on it. The foreman nods her head, all the drones are back. The convoy master simply points to the rovers, and doesn’t say a word. The operators let them go, at high speed for the ultimate stress test. They make it to the other side. They go a hundred kilometers an hour, and make it there in two minutes.
“Send the first wave!”

Microstory 2458: Diamond Dome

Would you believe it, centuries ago, diamonds were considered a precious commodity? They’re still precious, but they’re not nearly as rare and luxurious as they once were. Our ancestors would cut them up into pretty shapes, and fashion them into pretty jewelry. We don’t care about that. We care about function over form. Carbon is one of the most versatile elements in the universe, and as it turns out, its diamond form is actually extremely commonplace. It was hard to find on Earth when people were digging it out of the ground with shovels and pickaxes, but when you have the automation and power to manipulate entire planets, you start to see how abundant things are. We use diamonds because the stuff is durable and reliable. It’s also clear, making it a perfect, semi-natural alternative to glass. There are lab-grown polycarbonates out there that we can use instead, and to be sure, those are here on Castlebourne too, but nothing beats the OG super-material. We could also grow diamonds in a lab, but there’s plenty of it in this world, so why not take what the Lord giveth. Now, what exactly is it used for? Well, it’s the primary material for the domes. Most of the domes here aren’t perfectly smooth. They’re geodesic, which means they’re made up of a skeleton called a space frame. Traditionally, these were metallic, but these days, we use metamaterials; particularly graphene. Between the struts for the space frame, they affix transparent triangular panels, which allow you to see the other side. Why do they do this? Most of the domes use holographic skies anyway, so you’re seeing whatever the image is programmed to be. Well, I don’t really know. The tour didn’t explain that. It wouldn’t really be better if the entire dome were opaque with no hope of seeing the outside for real. Using a framework with clear panels is the most common way to design these things, and I just think they look nicer. You can turn the hologram off, and see the true Castlebournian sky, but if they weren’t made this way, that would not be possible. I guess it just gives us more options. A lot of people are afraid, believing that clear equals unsafe, but obviously that’s ridiculous. They think some meteorite could crash through, and suck out all the air, but that’s not really possible. Like I said, it’s made of diamonds, and even if it weren’t, your concern is unwarranted. Even if one panel does falter, these things are so gigantic that it would take days for all the air to escape, at worst. If it’s only one panel, it would take years. At any rate, there would be plenty of time for a drone team to fly up there and replace the panel, or panels. If there is so much damage that the dome rapidly becomes unbreathable, well, whatever caused that damage probably killed everyone on the surface anyway, so the air would be the least of their worries. Okay, I’ll end this on that happy note. Safe travels!
