Seriously, we started building things so massive that you literally can't see all of it at the same time unless you're in the air, riding in a magical skychair.
Exactly, yes! The LHC is so much more (larger isn't the right word, maybe massive?). If it was on the surface instead of being buried, and the earth was perfectly spherical, you wouldn't be able to see it standing in the middle of it, because the ring would be on the other side of the horizon all around you.
The ones in DC are pretty inspiring, too, in a Brutalist kind of way.
They're lit from below, so you can tell when a train is at a platform by the shadow it casts on the ceiling, which perfectly aligns with the recessed concrete blocks that make up said ceiling.
I looked up photos of about a dozen separate metro stations in DC, and... they're all the same design. I get pragmatism, but those are downright depressing. The only one I liked was Anacostia because the yellow overhead lights and the bright blue advertisement screen made interesting patterns reflecting off the water-damaged walls.
Compare that to Moscow: underground palaces. Marble, statues, reliefs, arches and columns, chandeliers everywhere. Hate the Soviets all you like, but they knew how to build beautiful.
I even like the ancient 81-series rolling stock, if only because of nostalgia.
