Great World Visualization

The Great World is a rotating, terraced Dyson sphere built on the exploitation of strong-force space-time geometry to support the cosmic stresses it entails. It is actively stabilized by a strong A.I. that has the energy output of a small star to make constant orbit corrections.

It takes one thousand of these feeder Great Worlds to build the full-sized structure with three billion times the landmass of the Earth- the equivalent of an entire galaxy's worth of statistically likely earth-like worlds. This one is 250,000 miles from end to end and uses an artificial star for its light source. The full-sized Great World uses a white dwarf which it contains inside of a Daymaker- a much smaller Dyson Sphere that limits the amount of light that can reach the terrace floors. Reflected light increases rapidly through the course of the day, so the Daymaker is at maximum output only for a short time. It converts excess energy into antimatter that is then shipped outward to be used to stabilize the orbit, which is inherently unstable.

The equivalent of earth-like gravity is achieved by rotating the entire structure. The equator has about 1.5g's while the mid-latitudes are right around 1g. Near the poles, the gravity drops to a very low fraction of one g.

The terrace walls are covered in miniature terraces (not included in this video, though I do have it modeled) that represent the zig-zags necessary to have a number of reflecting panels that serve three purposes. First, they reflect light from the central star so that light is equal throughout- the farther you are from the equator, the steeper the terrace walls and the more reflective surface there is. The terrace walls also represent part of the Great World's active radiative cooling apparatus, which operates during the night. The terrace walls also regulate the seasons by varying their reflectivity.

The Great World is, above all else, a "story space"-- a place where everything is inevitable, and variations in history that would be impossible on earth happen constantly. It is also a place of massive wildernesses, uncrossable oceans, and trans-epic journeys. Several of the poems in "The Promise World" are set there.

Im working on a story through painting and drawing which has a "Dysons sphere" the size of earth or Mar's orbit in it and this information would definitely be a help.

What is truly amazing is that if a project, more should I say WHEN a project like this becomes a reality, it would increase the carrying capacity of a civilization by a factor of the billions depending how large it is.

I also wonder how long would it take for an alian civilization to complete.

@curingaging00 I wish you endless inspiration in pursuit of your project. When I started working with this object in fiction, I treated it as a whole. I've since become more interested the "small story" that takes place on an "endless world"- often lasting hundreds or 1ks of years. Btw, GW is based on the idea that, in order to go the distance, any civilization capable of doing so must immediately sequester all others that might one day do the same to them. It's actually a "prison for cousins."

@curingaging00 As for how long, this version takes 10,000 years to build- most of which is spent gathering and transporting the materials across interstellar distances- in the form of a thousand habitable mini-GWs that are being finished and populated en route. In fact, the GW presented in the video is actually one of these 1/1000th scale mini's. Otherwise, you couldn't see individual continents!

How many Earth masses would a dysons sphere which would extend towards Mar's orbit need? And would it need to be made out of a super strong material such as Grafine or carbon nanotubes.

[deepskyfrontier]

@curingaging00 An verage specific gravity of 3 and an average material thickness of 3km, then it would mass in at around 5.6e30 kg, ~735 earths. It's safe to say that there's no possible baryonic matter strong enough to stand up to the stresses involved. So, while it would use lots of exotic carbon for local structure, the major load moments are managed by manipulating spacetime topology on the quantum scale and exploiting the nuclear strong force over vast distances.

Could you mak a video explaining this in more detail please. Looks awesome!

[curingaging00]

@deepskyfrontier Interesting thought, manipulation of space time and changing the bindings of atoms to be in favor of the dysons sphere. But as for Grafine, according to michio in theory Grafine could be made to be so strong that a sheet of grafine 1 molecule thick would not puncture through if you took a pencil then stack an elephant on top. I wonder if grafine could be made to be that strong would that alone be able to handle the stresses.

@curingaging00 And thank you for the great questions! It's a fun little thought experiment and I always appreciate a chance to revisit it.

[deepskyfrontier]

@curingaging00 You're absolutely right. Waste heat is a major concern. GW has a more conventional dyson swarm / sphere close to the star to create day/dusk/night, though nighttime IR does return inward. So, GW would get by on a K2V of about 0.8 solar masses which would normally have an early habitable zone ranging from 0.5 to 1.0 AU. A mature K2V (up-to 20B years) might extend from 0.6 to 1.4 AU. My model ranges from 1.0 to 2.0 AU (it's a 3D cyloid). Most important: outward facing IR radiators.

One problem with building a Dyson's sphere within the traditional HZ zone is that it would overheat, for the night time on rotating planets cools them down. One possible idea would be to create a Dyson's sphere much larger, beyond the traditional HZ zone. For the Sphere to have an average temperature for say about 60 degrees-90 degrees F how large do you think it would have to expand to? if it orbited a G2V star, sun like star.
