Spaceception

So I've been thinking about Alien (Or human, I'm not racist) space based structures as 'levels' (This is related to Infinitum btw)

Level 1, (I dunno what else to call it) Structures: Structures in space on the order of less than a klick to dozens of kilometers. Example, generation ships, O'neil colonies, etc.

Level 2, Superstructures: Structures in space on the order of hundreds to tens of thousands of kilometers. Example (imo) Dyson swarms (My opinion, since they're basically a crapload of O'neil colonies w/ a lotta solar panels in lots of orbits), etc

Level 3, Megastructures: Structures in space on the order of hundreds of thousands if not billions of kilometers. Example, Dyson spheres, ringworlds, etc.

Level 4, Superpower Ninja Turbo Neo Ultra hyper mega multi alpha meta extra uber prefix STRUCTURE (Get it?): Anything that can span light years really, I can't think of anything though.
