I grabbed the planet surface from nasa but, now I know the actual scale I'm going to have to redo it with satellite views of earth or something. You're right - the secondary sphere isn't a dyson, it's haditation, the exact right distance from the sun for human life to flourish. Gravity I've taken a bit of  liberty with - the hex sections would have to made of some kind of super dense something or other, cos if I had it spinning for centrifugal purposes the habitable are would only be a thin strip along one axis of the sphere. Fuck it - it's thousands of years in the future - they can do things like that then :P

Actually, no matter how dense the material is, there will be no gravity inside the sphere. But, I'm sure thousands of years in the future they can figure something out.

Also, do you plan on placing the original Earth in the picture?

Surely if the segments had enough mass? Each segment will weigh a million earths - wouldn't that help?

Hadn't really thought about it - I assumed this would be galaxies away.

blurb mk1 (lemme know if i've fucked up any of these numbers)

Everything begins with the Dyson Sphere. It takes just a little over two years to cap the star. Once this phase is completed the energy it generates is used to power the whole construction process. Next we begin harvesting planets. Thermonuclear "mole" charges are sent deep into the core of the planet, each one taking up a specific position, to form a cone shaped array of charges which are then detonated in unison. Our carbon factory collects the debris and converts it into pellets of pure carbon, each one with a mass in excess of two hundred and fifty thousand metric tons. These pellets are then fired directly into the Dyson's gravity well and collected there by the habisphere construction plant which turns them into hexagonal habisphere segments, each of which has an inhabitable surface area approximately three point six million times that of the earth.

Once the hex segment is completed it's moved out of orbit and fitted into place in the habisphere where terraforming begins. Our original solar sysem was capable of sustaining around ten billion souls, with energy resources stretched to beaking point. Most of our solar energy was just pouring out into space. A Habisphere can sustain more than five hundred million times that number with an energy supply that is never more than fifteen percent utilised, even at full population. This, ladies and gentlemen, is why we like to refer to our Habispheres as "Solar System 2.0"


We'll be arriving at Habisphere 57 in a few hours. Welcome to your new home!

No, the gravity from the closest segment would be cancelled out by the gravity of all the other segments. To stop everything on the inside of the shell from floating toward the sun artificial gravity would need to be generated.

(you can read more here, but there is a lot of maths http://en.wikipedia.org/wiki/Shell_theorem )

Oh right, my bad, I thought that this was our solar system.

TBH, this mass seems a bit low, if those are the pellets you can see forming a line into the factory. (Maybe 250 million would be better, that would give the pellet an approx volume of 1km cubed)

Edit:
Other numbers seem good though.

Cheers! Thas exactly the kind of thing I was after. I guess, gravity wise, I either go with a spinning ring (which I don't like the idea of) or I take artificial gravity as a given.

Iain M. Banks' (his Sci-Fi moniker) ways of getting around such things in a similarly advanced culture is to allow Mega Computers that have small presence in the "real" world (through ingenious jiggery pokery and fields and such) control things like gravity through similar use of fields. Just an idea, but you can assume if this is galaxies away then certain givens in Physics such as relativity and the seperation of forces (especially gravity) have been resolved or modified in such a way that a computer could manage that for you.

In any case, regardless of your need for a certain level of integrity in the image, the image itself looks purdy even in its unfinished state.

If you must know it's so they can spin it round and provide day/night cycles. 

You did base this on Larry Niven's Discworld, didn't you? If you didn't you should read it, because they do that exact sort of thing, except with a doube strip (like a belt, and one sort of dotted belt) instead of a sphere. It also contains the exact sort of scifi-wank that you're asking about, in the sense that Larry Niven actually thought out all this shit and made sure the numbers sort worked out (so you could steal them :-P). Plus the book itself aint bad either, I believe it has a zillion sequels, too, but I never read those.

[Rumckle]

Huh, my physics lecturer mentioned Niven in today's lecture (we were discussing Neutron Stars).

[Don Coyote]

Trip you mean Ringworld. Discworld is Terry Pratchett.

[Triple Zero]

yes.

AWESOME SHIT P3NT!!

tiny bit of criticism: I think the woman's head in the main picture might be slightly too bright, still?
