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!
