18:53.03 | Wormy_away | That the breakdown of the Galactic Empire leads to a dark age of communication in the galaxy. > Which could add some substance to Star Wars Legends.

19:11.18 | Roboticking | hello monet |
19:11.29 | Monet | hi |
19:15.54 | Ghel | Hello. |
19:16.14 | Ghel | You'd need a lot of plasma. But that goes for most weapons; you'd need a lot of them. |
19:16.56 | Ghel | The most powerful plasma and particle beam weapons are what most SporeWiki civilisations would use for orbital bombardment (if that's a tactic they use). |
19:17.32 | Ghel | In particular, you'd use fusion-grade plasma that basically acts as a fusion bomb when it hits the ground. |
19:20.03 | Roboticking | ah |
19:22.34 | Tek0516 | I suppose how you want to make it uninhabitable counts too: raise/lower the average surface temperature to no longer support life, remove the atmosphere, raise surface radiation to lethal levels, etc. |
19:22.58 | Roboticking | hmm, |
19:23.54 | Roboticking | would overcoming the gravitational binding energy of a planet be more efficient than orbital bombardment? |
19:24.10 | Tek0516 | No. |
19:24.27 | Tek0516 | Because that unsurprisingly takes vastly more energy. |
19:25.28 | Roboticking | True, are there any scenarios in the fictions were a nation glasses or bombards a planet? |
19:26.12 | Roboticking | (I ean like any fictions where such weapons have been mentioned or used) |
19:26.16 | Roboticking | mean* |
19:28.28 | Ghel | Yes. |
19:28.31 | Ghel | looks for one |
19:29.15 | Ghel | The Galactic Empire of Cyrannus has been mentioned to use it. |
19:29.42 | Ghel | Here's a picture: http://vignette2.wikia.nocookie.net/spore/images/a/a6/BaseDeltaZero.png/revision/latest?cb=20151009215912 |

19:29.56 | Ghel | Both from http://spore.wikia.com/wiki/Vehicle:Imperator-class_Star_Destroyer |
19:30.50 | Roboticking | thanks (I know you mentioned that most use it, but I wanted to get a link without having to look D:) |
19:30.53 | Monet | Most examples take fleets though for practicality reasons. |
19:31.07 | Roboticking | I see |
19:32.24 | Wormy_away | http://breakthrough.nationalgeographic.com/speculation/energy |
19:32.28 | Wormy_away | check out this site |
19:32.45 | Monet | Using a laser from a single ship to melt the crust of a planet has a few limitations. |
19:35.16 | Wormy_away | I prefer planet cracking to planet glassing |
19:36.14 | Roboticking | what would be the most effective way to crack a planet |
19:36.50 | Monet | A big enough impact. |
19:37.24 | Monet | Something like a highly resistant hypersonic projectile into the planet's crust. |
19:37.29 | Ghel | The DCP consider planet glassing to be unethical because it isn't an ostentatious enough form of destruction. |
19:37.50 | Ghel | That's basically what Wormy's saying. :P |
19:38.11 | Wormy_away | Yes |
19:38.21 | Wormy_away | EXTERMINATUS |
19:38.41 | Roboticking | Literally turning a planets surface to lava isnt enough? |
19:39.10 | Monet | That lava will cool down eventually. |
19:39.30 | Monet | PLanet cracking breaches the mantle and leaves a gash into said material. |
19:40.26 | Roboticking | true, and renders the planet uninhabitable |
19:40.41 | Wormy_away | Actually I am a bit sceptical of planet glassing - unless you are close to tier 1, getting enough energy to melt the crust of a planet would be a huge and long-term task |
19:40.58 | Tek0516 | I agree |
19:42.31 | Monet | Easiest option really is just bombard the planet until there's nothing but ash. |
19:42.41 | Ghel | You don't need to melt the whole crust; just the surface. But even that takes a lot of energy. |
19:43.04 | Wormy_away | You've still cover the entire planet's surface - if you are trying to glass the whole thing |
19:43.05 | Monet | Glassing jsut seems like some really extensive way to destroy any underground complexes. |
19:43.05 | Ghel | Although melting the entire crust will also get rid of underground bases. |
19:43.58 | Monet | Or if you control thep lanet, establish a sattelite network that drops hypervelocity projectiles on any emergent life signs that don't posess the right IFF. |
19:44.26 | Wormy_away | A heavy enough impact could lift the crust from the surface and force it to rain down on the planet in smaller impacts |
19:45.06 | Wormy_away | http://www.ufunk.net/wp-content/uploads/2015/03/Large-Asteroid-Impact-Simulation-6.jpg |
19:45.45 | Monet | Agreed. A powerful enough bombardment affects more than the immediate area. |
19:46.11 | Monet | Infact the iconic mushroom cloud or fireball is one of the smallest components of an explosion. |
19:46.34 | Ghel | Dyson sphere with gigantic relativistic cannon + asteroids + asteroid-sized wormholes = ability to crack any planet you can get a wormhole to. |
19:46.56 | Wormy_away | The Dyson Sphere could also create the Nicoll-Dyson beam |
19:47.14 | Wormy_away | Now that would be more efficient |
19:47.21 | Monet | The TNSS DOminax once used its superleaser to obliterate a TIAF surface garrison...and the mountain it was in. |
19:47.56 | Monet | The resulting impact caused a shockwave that spread across a hemisphere. |
19:48.50 | Ghel | As long as the Nicoll-Dyson beam doesn't destroy the wormhole, yes. |
19:49.37 | Ghel | Although I don't think having a relativistic asteroid enter the wormhole is going to be too good for the stress-energy tensor either. |
19:51.11 | Roboticking | Alas, I nust go for now, Farewell |
19:52.24 | Wormy_away | You keep reminding me how doomed we are because of the evil supercivilisation |
19:52.28 | Ghel | Actually, that makes me think of what would actually have happened to the wormholes after Project Exodus. |
19:53.14 | Ghel | The wormhole mouths at the exit end would have lost energy equivalent to the mass of everything passing through it; this could have been designed to be enough to complete destroy that wormhole mouth. |
19:53.47 | Ghel | Similarly, the entrance mouths would have gained the additional mass of an entire solar system entering it, and especially with the loss of the far end mouths, might have collapsed into black holes. |
19:54.39 | Wormy_away | Could there be a way to over-compensate to balance out this energy? I want a DCP weapon cache you see |
19:55.03 | Ghel | A million black holes isn't a weapons cache? :P |
19:55.20 | Ghel | Sure, just make the exit mouths bigger and the entrance mouths smaller if you have to. |
19:55.21 | Wormy_away | Wormhole bomb sounds cooler |
19:55.33 | Wormy_away | Which creates a black hole I assume |
19:55.46 | Ghel | Depends on what you do with it. |
19:56.04 | Ghel | Black holes are an option. |
19:56.06 | Wormy_away | By sticking more things in than they were designed to take? |
19:56.18 | Wormy_away | That would be a challenge |
19:56.29 | Ghel | I think there'd simply be some way to rearrange the structure so that it collapses. |
19:56.39 | Wormy_away | Since they can take the mass-energy of entire planets/stars |
19:57.07 | Wormy_ | There is Stephen Hawking's idea: feedback |
19:57.23 | Wormy_ | That would involve taking a wormhole mouth back in time |
19:57.44 | *** join/#sporewiki TekDroid (~TekDroid@134.117.249.83) |
19:58.02 | Wormy_ | But that might only work if the wormhole mouth was taken back to it's creation, hm |
19:59.44 | Wormy_ | Or maybe wormholes intersect, they divide violently, like a cosmic string would. But that is only thinking by analogy so probably wouldn't work. |
20:00.17 | Ghel | No, you just need to arrange the two wormhole mouths, and give one end enough time dilation, so the act of exiting one wormhole mouth puts you in the past light cone of you entering the other. |
20:01.06 | Ghel | So do you need access to both mouths and relativistic travel capabilities, but nothing else. |
20:02.50 | Wormy_ | I'm looking at the metric bomb on OA, it is similar |
20:03.34 | Wormy_ | But "wormhole bomb" is actually inspired by the Dalek weapon |
20:04.30 | Ghel | The shatterbomb might be another thing you could do with it. |
20:05.11 | Ghel | That depends on the relationship between wormholes and dark energy-like fields. |
20:07.08 | Ghel | As described on the page, what you'd need is another field that interacts with dark energy in such a way as to shift the value of the dark energy field to one where it has a higher energy. |
20:07.42 | Ghel | But we should be able to technobabble another solution if we had to. |
20:11.01 | Hachiman | Have you tried turning them off and on again |
20:12.18 | Ghel | The metric bomb in a single casing might work. Two charged wormhole mouths + small high-energy particle accelerator. The accelerator accelerates (of course) one mouth, it undergoes time dilation, and is repeatedly brought close back to the other mouth until the time dilation + proximity is too much. |
20:12.55 | Ghel | If it were possible to have only one charged wormhole mouth that would be even better, but then the charge would just go through the wormhole... |

20:17.35 | Wormy_ | lol |
20:17.36 | Monet | Lol |
20:18.11 | Monet | Do you think it says something about our opinion of the present when there are so many comics of Marty and Doc reacting in horror? |
20:18.50 | Xho | I'd say so |
20:19.18 | Monet | Shame because compared to holograms now this look shit http://backtothepredictions.com/wp-content/uploads/2015/02/jaws.png |
20:21.43 | Wormy_ | At least there are Flying Cars on the fringe https://en.wikipedia.org/wiki/Flying_car_(aircraft)#Real-world_flying_cars |
20:22.16 | Monet | There are three things where I think we exceeded BTTF 2's predictions: Mobile phones, holograms and the internet. |
20:22.30 | Technobliterator | wow |
20:22.34 | Technobliterator | new FPS game |
20:22.42 | Technobliterator | locks your account from ever playing it again when you die |
20:22.45 | Technobliterator | what an idiotic concept |
20:22.57 | OfficerJackal | What game is that? |
20:23.44 | Ghel | Monet: Mobile phones and the internet seemed to exceed nearly everyone's expectations. And computing in general, really, unless you count AIs. |
20:24.32 | Technobliterator | One Life it's called |
20:24.58 | Ghel | Although the real idea of a flying car is the ability to hover; it's not just a plane with a car-like cabin. Like hoverboards aren't actually supposed to be mini-Segways without the handlebars. |
20:25.53 | Ghel | You'd be better off getting your hopes up for warp drives than cars that fly like that, though. |
20:25.57 | Monet | I suppose one disadvantage to an actual flying car is you'd probaably need a pilot's license. |
20:27.23 | Ghel | Unless it's driverless (pilotless?), yeah. And crashes would be even more dangerous. |
20:28.17 | Ghel | And as if it's not bad enough hitting pigeons that don't take off from the road fast enough, you'll have the opportunity to hit an entire flock of them in flight. |
20:28.59 | Monet | From what I hear even driverless cars will require at least one person with a driver's license for various reasons. |
20:29.40 | Ghel | In case something goes wrong and you have to switch to manual control, I assume. |
20:29.50 | Monet | Yeah |
20:29.54 | Ghel | Eventually as the cars are shown to be more trustworthy than humans that would be phased out. |
20:30.28 | Wormy_ | Ghel: Do you mean magical cars which use antigravity or quantum phlebotinum? |
20:30.40 | Ghel | Pretty much, yes. |
20:31.05 | Ghel | If you're refering to my "better off getting your hopes up for warp drives" comment. |
20:31.12 | Wormy_ | Yeah, if anything like warp is possible, it would probably take until such tech is eveloped |
20:31.33 | Wormy_ | But whats wrong with a car shaped VTOL? |
20:31.57 | Technobliterator | I want them to invent a warp drive by 2063 |
20:32.04 | Technobliterator | but I bet Star Trek was wrong about that one :( |
20:32.12 | Ghel | There's nothing intrinsically wrong with the idea, but it's not really the traditional idea of a flying car. You know, wings and all that. |
20:32.59 | Wormy_ | It is not looking good for anything resembling warp technology. |
20:33.53 | Wormy_ | I don't think a lack of FTL bars us from interstellar travel. |
20:33.57 | Monet | I can guess one thing about the invention of warp drive: Unless there's a catastrophe it isn't looking like it could just be one guy with a disused ICBM and silo |
20:34.38 | Wormy_ | But I'm sure Ghel could point out that hyperspace suddenly looks more likely. |
20:35.05 | Ghel | If you want to really stretch your idea of hyperspace, yes. |
20:35.09 | *** join/#sporewiki DrodoEmpire (DrodoEmpir@blk-252-38-75.eastlink.ca) |
20:35.13 | Wormy_ | I can't remember the specifics but there is something about quantum gravity theories which role out warp bubbles, but not hyperspace. |
20:35.13 | Ghel | Hello. |
20:35.14 | DrodoEmpire | Hey everyone |
20:35.25 | Monet | Hi |
20:35.37 | Ghel | I'll explain it to you again, Wormy. |
20:35.51 | Technobliterator | I'm sure I read somewhere that warp drives were still possible theoretically |
20:36.00 | Wormy_ | Don't worry, I've got a pastie on the conversation. But other users here might want to hear it. |
20:36.14 | Ghel | Warp bubbles, and the negative-mass exotic matter required for such things in general, is not in a good position theoretically. |
20:37.15 | Monet | Actually just realised one thing to bear in mind about the future prediction in BTTF: It wasn't pinpoint accurate. |
20:37.17 | Ghel | Quantum field theory, which is what all of modern physics besides general relativity is based on, doesn't like it. Basically, it means that the lower-energy state of a field has more particles, so the vacuum will decay into negative-mass particles and positive-energy gravitons. |
20:37.23 | Ghel | That, obviously, has not happened. |
20:37.40 | Ghel | Now, it's often said that we need a theory of quantum gravity to know for sure. |
20:38.32 | Ghel | The problem with general relativity and why it doesn't fit into quantum field really comes down to what happens at extremely short distances, so essentially by preventing gravitational fields from changing over such short distances you solve the problem. |
20:38.36 | Monet | "We knew we weren't going to have flying cars by the year 2015, but God we had to have those in our movie." - Bob Gale, BTTF pt II producer |
20:38.40 | Ghel | That gives you two options: |
20:40.11 | Ghel | 1) make it so that, rather than existing point-by-point, fields such as gravity take values over extended objects, and you can actually get gravity that way using one-dimensional loops. This is what is known as string theory, and it basically agrees with quantum field theory. |
20:41.01 | Ghel | 2) make spacetime discrete, so the very concept of those smaller and smaller distances doesn't exist. This gives you quantum spacetime. Firstly, it probably agrees with quantum field theory too as far as warp drives are concerned. |
20:41.50 | Ghel | And secondly, with one particular approximation, causal dynamical triangulations, it was discovered that you simply can't have a spacetime resembling our own if you allow wormholes to exist. That's a fairly strong argument against exotic matter. |
20:43.25 | Ghel | As for "hyperspace", if we have two branes seperated by a timelike extra dimension, particles can move while oscillating between the two branes in such a way as to appear to go FTL. That doesn't seem to go up against either quantum gravity paradigm, but it does require a particular speculative model of reality to be correct. |
20:44.04 | Ghel | You could also have wormholes in Gauss-Bonnet gravity, which requires extra dimensions, but obviously that also won't work if you have quantum spacetime and the CDT result holds. |
20:44.21 | Wormy_ | Isn't CDT the theory that proposes spacetime has different states? Could the other states contain wormholes? |
20:44.32 | Monet | So we don't get hoverboards, would anyoen settle for a hover-model? http://kepfeltoltes.hu/150319/KELL6_www.kepfeltoltes.hu_.jpg |
20:45.20 | Wormy_ | Monet: Ordered this last week: http://i01.i.aliimg.com/wsphoto/v0/32298532837_1/Free-Shipping-Levitron-Ion-Revolution-Platform-Floating-Tabletop-Display-with-Ez-Float-Technology-Maximum-Bearing-Weight.jpg |
20:45.44 | Ghel | For the first question, yes. For the second question, no... |
20:46.29 | Ghel | Yes, you could describe non-causal dynamical triangulations where wormholes are allowed, and you would get other phases. |
20:46.36 | Wormy_ | I was hoping under " can't have a spacetime resembling our own" would mean that |
20:47.00 | Ghel | But the existence of wormholes isn't phase-dependent. |
20:47.58 | Ghel | It's a bit like asking "the non-existence of hydrogen would prevent liquid water from existing, but would it prevent water ice too?" |
20:48.30 | Ghel | Even the other phases of CDT spacetime would, I assume, not exist. |
20:49.30 | Ghel | And if they did, that's not relevant for our reality or anything remotely resembling it. |
20:50.50 | Ghel | IIRC, one of the other phases is where the causal structure of the universe is all broken up so you're not going to get any lasting emergent structures rising, and in the other it's all tangled up in a way which is hardly better. |
20:51.13 | Ghel | And non-causal dynamical triangulations was abandoned because its results were even worse. |
20:53.14 | Xho | This discussion kills the Xho |
20:53.41 | Wormy_ | When nature makes you feel like this dragon, doomed to only simulate 3D, but will always remain in 2D http://uploads5.wikiart.org/images/m-c-escher/dragon.jpg |
20:53.57 | Monet | Xho: I feel your pain. |
20:54.25 | Ghel | Well there's a picture of a dragon biting its tail to make you feel better. |
20:57.39 | Wormy_ | doesn't make me feel better |
20:58.23 | Ghel | It's to make Xho and Monet feel better by diverting their gaze from all the physics. |
20:59.06 | Ghel | I don't know how to help you with your existential crises. |
20:59.40 | Ghel | Me, I just got used to them ages ago so now I'm utterly desensitised. |
20:59.42 | Xho | https://soundcloud.com/turkeychickensandwich/crisis/s-hgeb1 I did a bit more of a Tool-ish song though it's still pretty heavy |
21:01.28 | Wormy_ | I'm desensitised to most except that one or the unseen obliviob |
21:01.31 | Wormy_ | oblivion |
21:02.08 | Wormy_ | That is, a false vacuum, simulation shutting down, or big rip, or nicoll-dyson beam heading our way |
21:02.21 | Wormy_ | or branes colliding |
21:02.53 | Wormy_ | But at least it would be painless |
21:03.18 | Wormy_ | well, it depends on the magnitude of the last one |
21:04.56 | Wormy_ | Ghel: Also, Stephen Baxter's Proxima series is based on this http://arxiv.org/abs/1009.4698 |
21:05.25 | Ghel | Ah, I remember that. |
21:13.00 | Wormy_ | Xho: Kind of goes with the existential angst |
21:13.11 | Xho | yuy |
21:16.11 | Ghel | It looks like similar reasoning to what I mentioned with quantum gravity: just like that can be taken as implying that there is a minimum physical distance scale, that paper argues that eternal inflation implies a maximum physical time scale. |
21:20.00 | Wormy_ | There's a similar paper which involves braneworlds, which after a certain duration of time, it changes into a different form |

22:54.24 | Monet | All from orbits I take it? |
22:55.02 | Monet | It's interesting how when they make a ring they create a sort of funnel around the Sun |
22:55.25 | Monet | A funnel that is apparently spinning |
22:57.38 | TekPC | They're all on circular orbits apparently aligned at the sun's equator at 1 AU |
22:58.39 | TekPC | It's really interesting to watch it happen, they kinda seem to funnel at a couple points. |
