Thoughts about sphere worlds

channel the energy and use it for your little projects...like moving the sphereworld, destroying black holes, creating pocket universes...you know, the little things.

And for those really adventourus mathemathicans:
Try to calculate the actual strength the sphere material need to have to stop it from collapsing at the poles (earth orbit, spinning so it has 1 G at equator), using all available building materials in the solar system (except the sun) for the construction.

You would have to discard the Atom and find another way to connect Quarks to get a material strong enough.

of course. get more articulate ducks.

i'm in a weird mood.

If the area is 550 million Earth-profiles, then I think you're probably going to want to import some material, or find away to make the sun pop you a bubble of matter to exactly the desired radius.

Good luck...

Heck, in the Star Trek universe, anything seems possible. But hey, that's supposed to be our future, so who knows. Anything could be possible. Maybe not in 10,000 lifetimes, but it could be possible.

To get around the problem with artificial gravity not being uniform inside a sphere world, maybe we could build the world so that it is not a solid one-piece sphere, but a combination of ring worlds stacked one on top of each other. So at the equator, you have a large diameter ring world, rotating to produce 1G of artificial gravity. Above and below this ring world, you have two more ring worlds of slightly smaller diameter, rotating at a different speed as to also produce 1G. Then, above and below those, have slightly smaller-diameter ring worlds rotating at its own speed to produce 1G, and so on. So the sphere world will consist of hundreds of ring worlds arranged in the shape of a sphere, with the largest ring at the equator and the smallest rings at the poles. The smallest rings will have to rotate the fastest to produce the same gravity. All the ring worlds could be enclosed in a larger, solid sphere so that it looks like a solid sphere world from the outside, but would consist of separate ring segments with independent rotations inside. Hmm, I guess this really isn't a sphere world...

but it is a Dyson's sphere. a Dyson's sphere just has to cover the entire sun.
