Bear in mind this would be half way between Mars and Earth. careful planning should eliminate much of the danger. In the event of an error producing possible earth crossers another asteroid could be accelerated to bump the errant planetoid off that course. Smaller errors could be compensated for by pelting the thing with rocks from the other side. And such errors should not occur as each hit could be modelled in advance and risk assessment could be constantly applied.

Hopefully by the time that (exodus) is necessary we will have solved FTL or similar short cuts. This would buy time for that discovery. Perhaps tripling the livable space in the solar system.

RE: the polymer idea.

I was thinking of not only would the Shielding be of course Benificial, But Might be used to make hollow tubes /Lifeline to connect the Asteroids to gether. If we used a couple of hollow Asteroids, connected together Like a giant Hamster cage, we wouldn't have to worry about Starting a Nuclear Furnace, And might be able to Control The planet better.

Besides that the effect of having your propossed shield would of course help Prevent the radiation out there.

I also seem to recall, Using an Iridium based Ceramic in the use of Superconducters, I don't know if the research ever panned out, But If so, and If there is a supply of Iridium out there, then It would be the perfect melding of those robots.

just a few random thoughts,

Stephen

Dyson Sphere is what they're calling it now? I thought they were calling it the "Death Star." Hmm. I suppose it wasn't PC enough.

I hate to rain on your parade, but do you know what introducing a large gravitational body to the balance we now enjoy would probably do to life on this planet?

1: The New Planet need not be close, for travel to be easy. If depends how you want to travel - cheap or often.

2: The problem I imagine is the atmosphere. There's a LOT of it needed to make a planet habitable, more than I suspect we are likely to find in the asteroid belt. The asteroid belt is theorized to be the remains of a planet or moon, and most of the atmosphere was lost, it does not remain there , if I remember my astrophysics correctly.

3: The other problem I imagine is the self-replicating robots themselves. Such Von Neuman - machines are an interesting concept, especially considering nano-technology, but wether it is workable.. well, it's a challenge, but we're talking the future, and it would be folly to say it will not be possible.

However, unlimited industrial capacity does not mean unlimited power, and such a robot horde would nearly need both.

I would ocnsider a space lens, to gather sunlight for heating the planet, rather than nudging it to a near - earth orbit. This could also, during construction, be used both for heating the planet core and an energy source.

Another problem, which I take less seriously, is that usually mentioned in science fiction - for some reason, such machines are almost invariably described as extremely dangerous and destroying their creators - the Berserks, for instance, or the machines in the terminator movies - or for that matter, the Matrix.

Yeah they might suddenly decide why build a new planet when they can just rid the earth of it's harmful infestation.

The glowing red eye travelling back and forth, the silver metallic bodies, arms at port arms, and the age old saying "by your command."

Irridium is a common as dust bunnies in the asteroid belt. The Yucatan impact spread a layer of irridium dust all over the world and that was one (1/2 mile wide???) asteroid. Well your right about one thing. Humans would be there in small numbers with the robots to monitor the work, most likely. So they would need shielding for thier base. But the melting would not be nuclear. It would be big solar ovens.

Nothing in all likelihood. Planetary alignments where all the planetary mass in the solar system is lined up do nothing to the Earth. The proposed planet's mass is already there in the belt. Nothing happens. Some of those bodies are already quite large Ceres is 1/4 the size of the Earth (perhaps just the moon?)

Storm is looking for a project so his robotics company stock shoots for the moon, hehehehehehehe...

Just kidding around my friend.

The planet would reside in the former asteroid belt not near earth. The Asteroid belt might not provide enough gas for the atmosphere but the Oort cloud and Kuiper belt certainly would. There is evidence that the oceans water originally came from cometary impacts over time. Likely the gravitational forces present during the formation of the original solar system destroyed the planet. That or impacts. Impacts could have also drove the atmosphere off. After that the solar wind would have driven it out of the area. An earth sized planet would hold an atmosphere. Mars is on the edge of being able to retain enough gas to be livable and it is 1/4 the size. the atmospheres gas content could be tuned to retain heat to compensate for the distance. CO2 water vapor and methane could be increased quite a bit without altering our ability to breath un aided. These would trap more heat. Mars does reach 80 degrees (briefly) in it's short summer and it would be further out than the planet I proposed.

The robots would each be idiot savants; brilliant at thier specialisation but otherwise dumber than a box of rocks. They would additionally have built in limitations including a termination clause upon completion of thier task. They would not be capable of altering thier basic programming and they would definitely not be sentient. Why go to the trouble of making them sentient when an automaton would perform better?

I have not looked at the economics beyond the need for replicating robots to achieve it. However; now that you mention it, the profit potential for such an industry would be enormous. Spin offs, minerals, technology...

Not mentioning real estate; I'd assumed the planet would be free for colonization. However at that future time some sort of framework for international cooperation might be necessary to avoid conflict over territorial disputes.

Stormbringer · « **Reply #36 on:** December 05, 2003, 07:40:48 pm »

I don't believe the mass would disturb the earth. I worry about altering it's orbit to ensure th orbit is stable where it is at The asteroid belt would describe the orbit I want it to stay at.

JMM · « **Reply #37 on:** December 05, 2003, 07:43:09 pm »

I will agree with you on that point Storm, we have no idea what kind of minerals are out there. I'd be laughing my arse off if someone hit a payload of gold and made it about the same value as silver. Of course the corp. cartel would hoarde it and not allow it to happen, just as the DeBeers cartel only releases a fraction of the available diamonds to keep the prices sky high. I imagine there is a lot to see and do out there, but unless we get reborn to learn another of life's lessons, I will not be around to see it.

You realise a Dyson sphere is mor ambitious and far more dangerous than what I'm suggesting. It is also far more vast than a planet. Dyson's sphere was ultimately a manufactured sphere encapsulating a star or a planet.

Stormbringer · « **Reply #39 on:** December 05, 2003, 07:48:06 pm »

It would take a big "meteor" to affect the orbit of an earth sized planet; likely one large enough to shatter it. The impactors that killed off the dinosaurs did not alter the Earths own orbit. My planet would be now where near earth. By Bode's law it would be half way between the Earth and Mars.
