How do you weaponize a Dyson Sphere?

>>52821915
Make it pump energy it collects back into the star causing it to go super nova or some shit.

I'm not an astrophysicist, so I don't know if it works like that, but whatever works.

>>52821915
It powers a giant not-death-star laser.

>>52821915
Move it. The amount of gravity it has should fuck up a solar system or something.

Make it move, and just fuck up everybody else's orbits.

put guns on it, you have several earths of surface area to play with and selective exposure of the stellar core inside causes the whole solar system to become a massive baryonic spacecraft

>>52821963
It doesn't.

Wouldn't just putting one of these on a star be enough to fuck up every planet in the system? I mean, you're literally putting a cap on their source of sunlight.

>>52821915
If you have a Dyson Sphere, you probably also have a giant fucking particle collider that spans its circumference and all the energy you'd ever need to run it.
Just accelerate some deuterium until you get some funky exotic matter, and use that to make doomsday weapons.

>>52821915
Like >>52822031 suggests: use it to 'steal' sunlight from a system.

Equip an FTL machines of your choice and visit enemy systems with it. Enjoy it as you pull out of orbit every planet in the system.

>>52821915
Make it a parabolic mirror, so that the radiation pressure causes it to accelerate towards whatever you want to not be there any more.

You'd need to make it massive enough to keep the star in place relative to it via gravitational attraction - although then you risk deforming the star and hence possibly reducing the core pressure too low for fusion to continue, but then again you're an interstellar civilisation with the capacity to build a Dyson sphere so I doubt such rudimentary problems of gravitation and fluid dynamics would be an issue for you.

Build your Dyson sphere around a red dwarf star that will outlive every main-sequence star that will ever exist. Use it to drive a stellar-scale computational engine. Retreat to arbitrarily-large numbers of simulated universes inside the sphere's computational mainframe. Never have to worry about anything ever again.

If you can build a Dyson sphere, why would you need to weaponize it? You'd have better luck weaponizing the component technologies and scientific principles that went into its construction. This is like asking how you weaponize velcro, instead of weaponizing the rockets you designed it to be used in.

The Sphere itself? Either move it as a weaponized rogue star or leave a panel open to devour worlds all war-planets/shadow raiders like.

The primary purpose is to maximize the energy usage of a star so just hook it up to a large enough weapons array and go to town

>>52821915
The act of building one kills any planets outside of it, anon.

Dyson Spheres ARE weapons.

>>52821915
Just the fact that you built one is enough for it to be a weapon. By building it you basically cover the main source of energy for all life in any habitable planet in the system the star is in.

When that happens, pretty much all photosynthetic life will die right off the bat. Then the animals that feed on those plants die, then the animals that feed on those animals, etc. The temperature on the planet will also drop to basically almost absolute zero due to their being no light whatsoever.

You'd basically kill the planet. The only thing that could possibly survive that are extremophiles living in the bottom of the ocean (as long as it doesn't completely freeze solid, which it still might), or beings that constructed bunkers or vaults to live in, but even then they won't last forever.

It won't happen immediately, but it will happen relatively fast, like over the course of a couple of months probably.

>>52822924
>It won't happen immediately, but it will happen relatively fast, like over the course of a couple of months probably.
That's not including the time it takes to actually construct the sphere, right?

Let's be honest - building a dyson sphere is an incredibly inefficient way of rendering a planet uninhabitable. You could glass the surface of a hundred million worlds with the reaction mass and building material you'd otherwise expend on the sphere.

And let's not forget, a dyson sphere is big and you aren't going to be putting it up overnight. If you have uncontested control of a star's sphere of influence sufficient to erect a dyson sphere, then you're already capable of subjugating any civilization that lives there.

Saying that building a dyson sphere is a good way to kill all life on a planet, is like saying that building a car is a good way to keep yourself cool in the summer.

>>52822475
You wouldn't even have to destroy the star to vaporize planets, just use mirrors and lenses to focus all it's radiant energy onto a laser.

>>52821915
All that power? Laser batteries. Or one huge fuckoff laser.

>>52823403
Now you're on the right track. Take all that abundant energy and convert it into a more portable, high-density form.

Use the dyson sphere to power an embarassingly large array of supercolliders and make shitloads of antimatter. You can't beat antimatter for energy density; it's not very energy efficient to make the stuff, but when you've got the entire energy output of a fucking star efficiency is not something you really give a shit about.

so what if one of the panels was a big magnifying glass could you slowly rotate it and burn planets and stuff?

I wasn't arguing whether it would be an efficient weapon, Dyson Spheres being useful for any efficient weapon is probably false. Even the efficiency of Dyson Spheres period is still argued.

Use the energy to modify space and time around it so it's basically undestructible, and then use its tremendous calculation power to calculate how to use it in the most efficient way to destroy what you want to destroy.

You basically built a god machine, so just ask him what to do

You people have no fucking imagination.

You're talking about a structure that is physically larger than our sun by a factor of two hundred.

You're talking about a structure that, if it were 20 cm thick, would mass 1.82 × 10^26 kilograms - that's 182,000,000,000,000,000,000,000,000 kilograms since I'd expect none of you faggots to be able to read scientific notation.

You're talking about a structure that can capture close to one hundred percent of a star's energy output. The Earth captures 4.5292×10^-10 percent (that's 0.000000045292%) of the Sun's energy, and that's enough that it can permanently blind you from seven hundred thousand kilometers away.

Not only that, you're talking about harnessing that output in a way that can be used to do something useful. Our sun puts out more energy per second than the entire human race consumes per year - BY A FACTOR OF TWO BILLION.

And all you cunts can come up with is "lol lets use it like a big laser".

No imagination. No sense of scale. No sense of wonder. I cannot imagine what life must be like for someone so dull.

>>52824161
>>52823900
You say to me not to diminish your dreams. I say to you that you aren't dreaming big enough.

>>52823950
>Even the efficiency of Dyson Spheres period is still argued.

Scale, anon, scale. A Dyson Sphere is the ultimate expression of the economics of scale. It doesn't matter how efficient it is, it can be one percent efficient and still capture enough energy in a second to power all of human civilization for millenia.

>>52824161
what more damage could you do than a supernova then with just one star?

>>52824161

desu I'm not sure how you could even utilise a fraction of a star's power. A mastery of tech at that scale is just beyond my imagination.

>>52824244
Dysentery spheres are a retarded idea ... you know what I'm not going to correct that... they are increadiblt costly to the point of absurdity it's far more practical to capture gasses from the sun to use for fission.

>>52821915
I just realized that an especially sadistic and practical alien species could torture an entire planet to death by building a Dyson Sphere while the planet's natives has no choice but to watch as their sun is slowly being covered by cold hard metal.

The aliens gets all of the solar energy while they get to kill off an entire planet's worth of life. Kill two birds with one stone, that kind of stuff.

>>52824333

Energy and mass are equivalent, what's to stop a super advanced race projecting a hot spot onto a planet glassing everything there. Or pumping so much energy into an area to create a black hole.

>>52824161
Well what's your fucking plan genius, I see you shit talking but I don't see you coming up with any weapons.

We're using a fraction of the Sun's output right now. It's called solar power, look it up.

>>52824161
>You're talking about a structure that can capture close to one hundred percent of a star's energy output. The Earth captures 4.5292×10^-10 percent (that's 0.000000045292%) of the Sun's energy, and that's enough that it can permanently blind you from seven hundred thousand kilometers away.

Uh, if the sun was that close, we'd have worse things to worry about than going blind...

No sense of scale you say?

>>52823499
Why bother converting anything, though?
Just use superconductor magnets to channel the star's plasma. Now you have a fuckoff huge plasma beam that spews radiation.
Or you can just focus gamma rays wherever.

>>52821915
Use the economic boost to support a huge fleet and make something like schindelghiest 4

>>52822555
The radiation pressure would be massive and eject it from the sun.

>>52824835
going to go with "because plasma doesn't work that way"

Easy.
1. Make your dyson sphere out of computronium.
2. Make it host an AGI.
3. Task the AGI with defeating your enemies.

I'm pretty sure its plan will involve nano- or femtomachines and result in the universe becoming uninhabitable.

I feel once you get to the point where you can throw planets at each other anything beyond that is just pure spite.

>>52821915
Trick your enemies into building one and laugh as they waste heaps of resources in trying to construct an impossible construct

Economic MAD. Encourage it to be used an industrial base and freely allow usage of the power. Soon becomes an important economic hub. Orbital shipyards, massive supercomputers, farms and factories all attracted by low tax rates, regulation and free power.

Become so economically intertwined with enemies and wider communities that any attack would massively disrupt the system economy. Would cause an economic crash which would destabilize all colonized space and kill billions.

>>52825466
Well done, anon. Well done indeed.

>>52824835
>focus gamma rays

turn your enemies into Hulks

It's going to need communication, and energy transportation. Lasers are a common, efficient means for freespace comms.

Simply redirect one of those communications lasers at the target. Even a tiny fraction of solar energy makes most scifi warship weapon look like popguns.

Build a fleet of them.

>>52825046
How DOES it work, then, o master of stellar dynamics, electromagnetism, and nuclear physics?
Why, with superconductors and a nigh-unlimited source of energy, can we not blast fusing hydrogen at things from a dyson sphere?

The dyson sphere itself is a weapon. Add a drive to one side, magnetically confine the sun, and boost it into a system from afar. One you arrive, even a nearby-ish pass will fuck up a system.

>>52823912
Mirrors.

>>52826805

Because of a little thing called the inverse-square law.

That'll just heat the mirrors until they've reached thermal equilibrium with the surface of the star. Then the sphere will start losing heat to black body radiation.

I'm not actually sure how you could induce a nova on a star externally. Stars go nova when they deplete the light elements in their cores and can no longer sustain fusion.

How do some AI just fucking explode tech wise? Like I was sitting on a 20 planet empire with a 20 cruiser 30 destroyer 40 corvet fleet at around 20k power. I decided to eat half of a small 4 planet empire to round out my borders for that nice spherical blob and this fucker was at "overwhelming" I didn't even have space station level 6 yet. I was still at level 2 kinetics and he was throwing around Extradimensional Weaponry level 4 kenetics level 4 lasers. His shields were literally so powerful I couldn't kill his transport ships. After I somehow mulched his fleet he sent 13 corvets at me and the game was telling me it was a 9k power fleet. I mulched it only through pure numbers. He managed to kill 12 of my cruisers 6 destroyers and 2 corvets. 13 corvets vs 90 fucking ships and they came out with a better kdr.

I don't have advanced starts on and this faggot only had 4 planets. He was buddy buddy with another empire who was also classified as "overwhelming" but he only had 2 planets. I had 4 really good tech planets pumping out research and they far outstripped me.

Its got to be something from the updates because this never happened at release. An empires size was a good rule of thumb for their tech level.

>>52822095

Shhh I thought I was on /v/ for a second. But yeah they were just normal empires. I would of noticed 4 or 5 40k doom stacks in my face if they were. Unless they somehow got the fallen empire to give them a research boost or something which may be a thing now I don't see how in the hell they got so far.

>>52828567
Normal. I've played two games since the update and since I haven't played since launch I wanted it to be "fair" so I could learn all the new shit they shoved in.

>>52828593
I havnt played much utopia. On the last patch with no advanced starts and its not a fallen empire there is no way that they should have had anything like that.

>>52828422
On the bright side, researching the resulting debris should have advanced your weapons by a huge amount.

>>52828422

You have a +10% extra research cost per planet for having more planets. That's why bigger empires have to dedicate whole sectors to research.

>>52828630
Which is why I'm asking Its happened in two games so it has to be some change I am not aware of maybe an event? There are three fallen empires two way the fuck up top both of which are prickly fucks that don't want you existing near them and own a good deal of land. Then there is a small as fuck fallen empire that is the xenophile one but they have like one system.

>>52828681
Oh yeah that's how I figures out they had all that shit. They even had jump drives. The next time I ware them the wrecks should give me the full tech. Thats always fine in the end but I want to know how it got to that point to start with. I want to be able to properly evaluate my enemies and know how the system works.

>>52828703
Even factoring that in they simply had to much. I could understand if they hardlined their main weapons tech and maybe just shield tech but it was across the board. They had EVERYTHING including jumpdrives.

The two planets I took weren't much of anything really one was a farm world and one was a mix of energy and minerals. Only one research building between the two. So unless the other two I have yet to get to are nothing but research which I doubt and even then I don't think they could simply have just so many late game techs.

>>52821915
Use it to power an accelerator all the way around and throw random shit at whatever you want gone.

>>52828574
>Shhh I thought I was on /v/ for a second.
You can be forgiven for making that mistake, seeing as /tg/ has two active threads about the new Dawn of War videogame.

>>52824984
Weigh it and position it so the gravity from the mass of the dyson sphere counteracts it?

>>52829116
The shell would be less massive than the star. Also, Shell Theorem.

>>52828707
Probably they were in a war with a fallen empire before and stole their tech.

>>52821915
Most interesting use for Dyson Sphere's I've ever seen was in Linda Nagata's Nanotech Succession series where humanity uses them to hide the light of the star from view so aliens will pass by them on their endless planet glassing spree throughout the galaxy.

When stars start coming back because the spheres are falling apart or being dismantled for some reason, the implication is that the main human civilization is FUUUUUUUUCKED at this point.

>>52828270
Thats pretty simple, all you have to do is introduce Iron into the stars core, it will then go supernova as it tries and fails to fuse the Iron into heavier elements.

>>52831058
How do you get enough iron into the core of a star?

>>52831644
I don't know, perhaps you heat Iron to it's plasma state and throw it at the star it should theoretically sink deeper in because it's denser than anything else in the star, maybe? Really though, all I know is that Iron is what causes Supernovae, if you don't believe me, look it up.

>>52828752
Unity. You can farm Unity faster with smaller empire. If he invested in research tree he could probably pull it off. Especially if he had a research agreement with his neighbour and they going for different research.

Look up Nicol Dyson Beams, Isaac Arthur has a great video here.

https://youtu.be/RjtFnWh53z0

In short, assuming ftl doesn't exist, you could easily have RKVs or the beams themselves on route to every planet that has a chance of developing life in the galaxy in just a few thousand years. You know, if you really want to make sure you're the only kid on the block.
This only works if they don't have space habitats or their own Dyson swarms, because there's not much to do at that point but learn to get along.
It's part of why we should be getting self sufficient space colonies going asap. Planets are targets, eliminating them all is simply logical, space habitats are mobile so are immune to interstellar weaponry.
Really there's not much you can't do with a Dyson swarm, fly the Star, shoot lasers, Transmutation, etc.

>>52824379
You capture the gases for fusion anon, and the ideas are not exclusive. You build solar collectors to power a huff and puff particle accelerator around the Star for stellar lifting. More solar collectors to run the magnetic field to catch the atoms in the artificial solar flare. Those atoms can be used as fusion fuel all the way up to iron, and past that you can use particle accelerators again to transmute to heavier elements if desired. All these elements can be used as construction materials for more and more habitats, likely with solar collectors since you might as well save the fusion fuel for things further away from the Star with little light, and to just expand the production system as a whole. Excess fuel that you don't need at the moment can be stored in artificial gas giants, likely with shell world's built around them.
At this point your star is mostly occluded anyway, and it's just a continuing process until you have a complete Dyson swarm.

assuming we previously learned to synthesize the material needed to create the dyson sphere- mining, refining and shipping would otherwise be a nightmare of logistics- we -could- use the limitless amounts of energy harnessed into creating genesis devices en mass, but since its infinitely more complicated to create than it is to destroy, the sheer amount of tedious work involved might drive people into insanity.

why? because who wants an empire of IDENTICAL PLANETS when you can have fully customized ones, ready to order. but that would be an absolute time sink, not to mention we'd eventually piss something off by continually terraforming every planet and system we come across.

Well shit, someone already beat me to it, with the same video I was gonna link.

I dunno if he mentioned it in that particular video, but with that kind of energy, RKM's are easy as pie to send out by the truckloads. You could sterilize the galaxy if you had enough people/sensors picking out targets.
