Default Dyson Sphere?

I can not find anywhere that says that the outsider is in a dyson sphere, or that there is a dyson sphere.

Yup, isn't conjecture good?

The part at the back of the Necron codex makes some mention of the Nids moving out of their way to avoid an object, this object is either very big, very bright, or both. Somehow, someone put these together and came up with the Dyson sphere idea, a big thing wrapped around a sun.

So what's your theory?

Well, a Dyson sphere should not radiate any light, Because it completely relies on heat and light for energy. I would figure some sort of imprisonment thing. (possibly made by the eldar gods.)

I thought I read somewhere that the new squats, or Demiurg, however they are spelt, built the dyson spheres. I could be totally wrong though. I would however disagree with it being invisable due to light, They only absorb on the inside, not the outside, and are extreemly massive as they can surround a star.

Big, and shiny on the outside.

The name and idea of the dyson sphere comes from an episode of star trek. Someone probably read the necron book, then saw the episode on TV the same day

Nope, I can happily say star trek had nothing to do with the development of the Dyson Sphere theory. It was thought up by an astronaut in 1959. He did admit, though, that he was inspired by a 1930's movie.

:claps his hands together and rubs them:

Ahhh. Science fiction. I love science fiction.

Let's break this theory down a bit:

Very big or very bright or both
Made the Nids go around it

Further questions:
Should Dyson spheres radiate light?

Let's begin with random stuff about Dyson spheres, because I'm bored and need something to do.

Essentially, a Dyson sphere is a sphere built around the sun. However, with that, there comes a few glitches:

As you can imagine, this thing has to be HUGE to get a decent range away from the sun, mainly so that you can have a breatheable air that doesn't get ignited by the sun's heat. This can be solved by spinning the sphere so that you only have to have a thin layer of oxygen on the inside. However, then you get into balance problems, and you have to have some way to balance it so that it doesn't get off center and drive into the sun. Then you think about how much gravity you are exposed to when you are that close to a star, and you realize that, even if you can keep it perfectly on balance and have the gravity equal all over the sphere, the sphere has to be nearly perfect, so the architecture for it has to be nigh-flawless.

Then, you have to make it out of a material that won't be torn to shreds by random cosmic junk, and also so that your enemy can't come up and blow your sphere to shreds, costing you astronomical amounts of money. But when you think of cosmic stuff, you also have to remove everything from around the sun, IE: Comets, planets, etc. so that they don't blow a hole in your sphere. Then you consider just how much of that material you need...

So you see, it just because a nearly endless list of random stuff you have to deal with in building one.

But, if they some how got one built, let's consider the 'myth' for lack of a better word.

Being Very Big
Well yeah, it's gunna be huge. But a Star is kinda huge. So what are you defining as huge? But a Dyson Sphere would be absolutely monstrous, so I can see this part being true.

Being Very Bright
Here we come to the sketchier ground. It wouldn't be any brighter than a sun, so they'd be avoiding the sun, anyways. But what could be interesting, is if you assume that Tyranids use Infrared vision. Then this begins to make lots and lots of sense. You take a very condensed star that is very bright infrared, but they are used to it. Expand that a couple thousand times, and you have this gigantic sphere, that is shining comparably to a star, but at thousands and thousands of the size. So if the Tyranids use Infrared vision, this could make lots of sense.

Which brings us to the other question that was proposed. Should a Dyson sphere radiate light? Well, it really depends on what kind. But I think that the Tyranids are going to be using infrared or some other spectrum of light, because the visiable band is very small, and we could quite possibly be seen as inferior for using it by some species.

So really, it comes down to what kind of 'vision' Tyranids use. If they use Infrared, it's probably a Dyson sphere, and all of this makes sense. If they use visible light... This just doesn't hold water at allllll.

If you actually read all of that... Bravo. I was bored.

A little known fact: The Dyson sphere was created by James Dyson, the inventor of the Dyson line of vacuums. How he was alive hundreds of thousands of years ago, and why he was in collusion with the Eldar, we may never know.
