Largest Megastructures in Sci-Fi

[Korten12]

What do you think the biggest Megastructure is in Sci-Fi? Obviouslly there is many of them, and some may be bigger but not as widely known.

I think at the moment that is is the Shield World in Halo, the one in Ghosts of Onyx and Glasslands, is 2.55036e+17 (500 Million times the surface area of Earth) or 255 quadrillion km2.

So post what you think is the largest Megastrucutre is!

The place where they construct planets in The Hitchhiker's Guide To The Galaxy is 13 light seconds across, or 3,897,301,954 metres. Which would be... 190,870,132,282,126,866,381.2 m[sup]2[/sup]. So, roughly 190.87 quintillion m[sup]2[/sup].

Your move.

I was going to go with the Corellian System [http://starwars.wikia.com/wiki/Corellian_system] in the Star Wars EU, but the Hitchhiker's Guide one utterly trumps that. Fuck.

Only the Culture or something is going to beat that.

EDIT: GOT ONE! The Galaxy pendant in Men in Black!!
That's got a whole galaxy in it, so approximately 4.1x10^48 m^3. That's:

4,100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000m^3

Wouldn't it be a Dyson Sphere? I mean, stars are pretty big, and you'd have to build an enclosure around one...

We're already way beyond Dyson Sphere's my friend. Look at the above posts!

What about the mechs at the very end of Gurren Lagann? Weren't they throwing galaxies at each other?

I hate to be 'that guy' here but...

Technically the hitch hikers one doesn't count as the book says it's a closed loop of hyperspace so it's not really a structure as such, more of a place.

I'd go with Loop Stricken and say Dyson sphere

It's still 'constructed' though (it's a big shipyard within in the hyperspace loop), so is technically a megastructure. And, more importantly (pseudo-arrogance btw) does my suggestion [http://www.escapistmagazine.com/forums/read/18.370599-Largest-Megastructures-in-Sci-Fi#14345965] count?

Hmm that really depends on your definition of what a megastructure is. Is a large collection of smaller associated structures considered a megastructure?

The Ark from Halo

And you thought a Halo ring was big!

Yeah I think they were. Don't think anyones gonna top this.

 

[Hal10k]

The UAC towards the end of Isaac Asimov's The Last Question has spread its receptors and processes throughout the entire universe. It isn't a single physical structure, but I think it counts.

Those are Mech's. Even if's really large, It doesn't quite qualify as a Megastructure as it is a mech.

 

[drednoahl]

If I remember correctly, the maximum size of structure built is classed by the Kardashev scale.
I'm pretty sure "someone clever" worked out that a type 4 civilisation could not exist in our universe yet though because our universe isn't old enough, but they're the guys who would theoretically be building megastructures.

A type 4 civilisation should theoretically be able to construct a megasphere that takes something like 1200 galactic masses to cover 200 light years (numbers might be a bit off.) Much bigger than that and it would most likely turn into a massive black hole. That makes the assumption that the type 4 civilisation needs an atmosphere similar to humanity though. Some folks believe that voids in space (such as the Bootes void) have been harvested for use in big constructions by advanced civilisations, but that just made me think of Dyson spheres made by the vacuum cleaner manufacturer, not aliens.

I don't know how big a Dyson Sphere would actually BE.

Also RE: the MiB pendant, Frank said it himself that it's very very small.

I'd disagree on the distinction between mech and structure being relevant to the purposes of this discussion, but I'd still blow it off as being too stupid to be considered.

It clearly isn't that many meters at all. It is an entire galaxy in the size of a marble, so the galaxy is the size of the that marble.
I suppose that maybe the aliens playing with our galaxy at the end of the movie might count for something. Maybe the bag that they put it in?

Guys guys, the real answer here is your mother.

i would have thought it was '42' ......

In one of the Inheritance Trilogy by Ian Douglas, an ancient sentient robot race built a Dyson Sphere around the supermassive black hole at the center of the Milky Way.
