A Ringworld would be more likely than a Dyson sphere, the mass requirements are so much lower.
Wouldn't a Dyson swarm be much easier to construct than either? Like a dyson sphere but a swarm of smaller collectors.
A swam doesn't produce anywhere near the real estate though. So I guess it really depends entirely on why the megastructure was built, if it's only for energy extraction then yeah, a Dyson swarm makes the most sense. But if they also want to use it for habitation then it's not a really great idea. Sure you can spread space station's throughout the swarm, but then groups in space station A are always going to find it difficult to interact with groups in space station B, no matter how commonplace space travel is. It would be like intentionally building two cities on either side of a canyon, and saying it's okay because aircraft exist.
But it’s unstable.
So is a Dyson sphere?
Spheres aren’t unstable around a star. Rings are unstable in orbit around a star.
If a civilization can figure out how to make one, they can keep it from sliding into the sun!
Like how if they figure out how to build an 833' long ship they can keep it from immediately hitting an iceberg and sinking?
Or the most advanced starship in the galaxy not having a Spontaneous Massive Existence Failure
We could just ask the mice.
Damn, imagine the number of lifeboats you’d need to evacuate a Dyson Sphere?
At least we know what the band will be playing
Where you gonna go?
You know, that's a really good point, but this is on such a bigger scale and if it's a known problem today, I think they would know about it by the time they can build something like that.
Just glue 3 of them together, that'll make them 300% stable!
220, 221. Whatever it takes!
RTFA they are looking for swarms, rings, and other subtypes of Dyson Spheres.
I read the fucking article. What makes you fucking think I didn't?
The fact that you just reiterated one of its points.
Huh. So commenting on the content of the article means it wasn't read? That's a really odd position to take.
Easy there cowboy
Ringworlds are not orbitally stable so they are firmly in the realm of sci fi.
Neither are Dyson spears
what's ringworld?
https://en.m.wikipedia.org/wiki/Ringworld_series
Imagine a slice of a Dyson sphere, about one earth wide and one earth deep.
Or the halo from the game 'halo'
Though its important to note that the halos aren't true ringworlds, they aren't nearly big enough.
I guess the big difference is it doesn't encircle the sun
Basically. The the whole idea is that it's 1 AU out so it's in the habitable zone, spinning fast enough to simulate 1 gravity. Stats for nerds.
Also known as a Banks orbital.
Yeah. Ringworld was written way before that and Dyson thought it was a cool idea. Glad to see it used in other stories.
