[01:28:42] Good afternoon Scolar_Visari. [01:29:11] Afternoon? I'm on a tidally locked world, there is only noon. [01:29:37] only Nuun [01:30:07] This does mean, however, that telling time is rather difficult. [01:30:59] Action: Scolar_Visari recalls pre-accurate time keeping for longitude measurements on Earth involved some rather precise astronomical observations. [01:32:26] I suppose a plausible tidally locked habitable world (one orbiting a red dwarf) would have some neighboring planets close enough to make their measurements relatively easy? [01:35:13] "Dark Matter, really? Something that has gravity but no mass? Silliness." [01:35:40] Action: Scolar_Visari begins to ponder if they should be called WIPs now instead. [01:36:35] Or perhaps they're simply not up to date and still think neutrinos are massless? [01:36:37] ¯\_(Ä)_/¯ [01:36:52] wait, what? [01:37:23] Also, neutrinos are far too hot. >_> [01:38:02] Yeah, but, old Standard Model had them massless. [01:38:16] Then Nu Standard Model came around with its viral upsourcing. [01:42:21] Oh dear. "I still hold to the theory that dark matter is really just a lot of black holes. Occam's Razor." [01:42:46] uh [01:43:24] I have bad news for them about microlensing and Hawking radiation. [01:45:07] "And to think that we are going to let the Hubble die in just a few more years. Everyone at NASA wants to say that the replacement will be great, but Hubble is a light telescope while the replacement will be a radio telescope." [01:45:16] Today I learned: The JWST is a radio telescope. [01:45:25] That would account for the recent delay! [01:46:28] well if it's not MACHOs then how the heck would it be black holes? [01:46:59] Supernovy: I don't think they were aware MACHOs have fallen out of favor. [01:47:27] alright, time to get some game time in and hopefully build this stupid satellite subassembly [01:47:42] Then again, I think 99.99% of the, ahem, "criticism" leveled towards dark matter is made by people who haven't read any technical literature on the subject. [01:48:14] I'm more curious about dark energy than dark matter, it just seems implausible [01:48:23] RhineBTV: It's a place holder name, nothing more. [01:48:35] I jsut mean in terms of what it's supposed to do [01:48:58] Well, the Universe is visibly expanding at an accelerating rate. [01:49:03] It's to do with the expansion of the universe. [01:49:05] It's supposed to be responsible for the acceleration of expansion, but wouldn't that mean that it would have to be filling in the space it's also responsible for creating? [01:49:06] Whatever's causing that is Dark Energy. [01:49:11] That's what I mean [01:49:23] RhineBTV: Not necessarily. [01:49:24] In order to continue that same acceleration of expansion [01:50:01] That's the sort of view Lawrence Krauss takes, that dark energy has something to do with vacuum energy. [01:50:58] I don't know too much about it, I'm not a super space-nerd, I just really like ksp, but the whole dark energy thing has always caught my eye [01:51:04] I read whatever when I come across it [01:51:58] To be honest, the cosmologists don't know that much about dark energy either. If they did, they'd give it a better name. [01:52:18] Yeah, it's all hypothetical at this point, it just never made much sense to me the way it's proposed [01:52:36] Supernovy: "The Force". [01:52:37] I'm sure once the model is filled out more, it ends up being fifty different things that explain the process [01:53:22] It's not so much a model as it is, again, simply a place holder name for a natural phenomenon. [01:53:43] Like dark matter, though we have a somewhat better understanding of what that is and isn't (coughnotMACHOscough). [01:53:51] Using the term loosely, just whatever ends up being there for us to figure out when we get there [01:56:03] I keep forgetting I need to reinstall scattere [01:57:40] Action: Scolar_Visari blames video games. [01:58:18] It's like if you saw a shadow, and said "hey, there must be a shadow casting object", and people got on your case about it. [01:59:29] Supernovy: "I take umbrage at your fudge factor!" [02:00:36] it's all ksp's fault [02:01:13] Pokemon also has a lot to answer for in regards to misunderstandings of Evolution. [02:02:56] hah [02:03:04] "Believing you can use a telescope to look into the past is as silly as believing you can use a microscope to look into the future. Light information happens in a quantum instant!" [02:03:15] Alright, I need to figure out a limit for myself regarding what I'm going to let myself do in terms of clipping [02:03:25] Action: Scolar_Visari ponders why satellite internet has such terrible ping. [02:04:04] I think it'll be cool to make this bay open up via IR telescopic pistons to access the instruments, but what is reasonable [02:06:09] Does that second sentence actually have a meaning? [02:10:34] Supernovy: Looks like word salad to me. Tossed, with moldy croutons and lots of ranch dressing. [02:10:51] Perhaps tell him that it's actually heavy information? [02:11:20] I'm afraid they won't understand the gravity of the situation. [02:11:24] And it happens in a classical instant, which is continuous. [02:12:36] Oh dear, that'll also mean we'll need a medium for the transmission of light. [02:13:08] There's a pun in there somewhere, but I don't have it in me to find it [02:14:18] "gr was falsified about 30 seconds after publication by 3rd graders everywhere before recess when they realized that "TIME" is a CONCEPT and it can't be Manipulated... (Dilated, Warped, Bent) or anything else. It's a Full on Reification Fallacy, IN TOTO." [02:16:07] I'm assuming these are the same 3rd graders that believe rockets can't work in a vacuum? [02:20:03] Oh my. "If CO2 was a greenhouse gas then it would trap the heat created by sunlight in the daytime at night." [02:20:28] Phew, now we can't toss away more than a century of physics on the matter of greenhouse gasses! [02:23:26] "According to the double slit experiment the particle does not exist until it is observed or detected. Energy is in a wave state traveling at the speed of light, timeless too. As soon as it is measured the particle becomes physical and pops into existence." [02:23:43] I'm not entirely sure that's how the double slit experiment works. [02:27:29] Where is this coming from? [02:29:16] I really am my own worst enemy when it comes to certain aspects of design in KSP. I can spend hours staring at the walls I build for myself between functionality, aesthetics, and believability [02:29:36] Yahoo! is a gold mine for quackery. [02:29:46] Yahoo! Answers? [02:30:02] Oh, no, the comments sections for the poorly formated news pages. [02:30:07] oh [02:30:19] I'm surprised people still actually use Yahoo [02:30:27] It's like people who still have aol e-mail accounts [02:30:39] Little relics of a different era of the internet [02:30:52] Didn't Yahoo buy tumblr? [02:31:23] Supernovy: What they really needed to buy was a decent web page designer. [02:31:47] For some reason, their sites have gotten measurably WORSE. [02:31:52] My favorite part of tumblr is the dude who created it said he wouldn't have if he knew what it was going to turn into [02:31:59] Or he would've done it differently [02:34:56] Supernovy: I'm of the mind that whoever is in charge of web development for Yahoo is actually a group of untrained pigeons pecking at keyboards. [02:35:07] That is, if they get something right, it's by accident. [02:35:34] Oh, I thought you meant "They're writing Shakespeare instead of CSS" [02:35:55] But that's monkeys, not pigeons. [02:36:41] "I always wondered, if we can convert light into electricity, which is a small portion of the EM spectrum, why can't we convert the other spectrums which are not visible but contain more energy, like the microwave, x-ray and or gamma ray spectrums?" [02:37:05] Really makes ya think [02:37:14] So much we're not taking advantage of [02:37:36] Just all this free energy sitting out there [02:37:37] If only the Sun produced more of those wavelengths and if only our atmosphere didn't readily absorb them. [02:38:20] Oh, they meant just from the sun [02:38:49] I thought it was someone who was oblivious to technology that's existed for a hundred years [02:39:51] Though microwave transmission is totally a thing, however, it doesn't work best with photovoltaics. [02:40:15] It's almost as if different wavelengths have different properties!!! [02:45:38] Action: Scolar_Visari goes off to make the Sun radiate more energy in ionizing wavelengths. What could go wrong!? [02:46:06] Put some metal in the microwave, and you'll see other parts of the spectrum produce electricity. [02:55:05] scansat parts don't actually need to be aimed towards the body, right?

[07:28:56] Problem happens too high for chutes [07:29:55] Unless maybe I use that ballute mod but then controlling where it lands would be an issue [07:30:07] Cause it's gotta be on land, not water [07:31:29] pairs of chutes, just pair of chutes. [07:32:15] Drogue chutes? I have to bleed off over 6 km/s of speed [07:38:55] lithobreaking. [07:39:02] lol [07:39:18] That atmo might as well be rock right now [07:39:28] The problem is that it's rather shallow [07:39:44] About half the height of Kerbin's but 10 times as thick [07:39:51] you can always do a complete stop and then descend :) [07:40:28] Yea... that just sounds like a broken atmo. [07:40:52] It's evil lol [07:45:42] But I guess it's "realistic" since the surface g is 1.9 [07:45:55] There was that mod that compressed Eve's atmo [07:46:06] And expanded Duna's [07:49:08] Well, the gasses should be compressed due to the weight of the gasses above them... which means regardless of the force of gravity; the density of the atmo should only depend on the composition and volume above the CoG. [07:49:38] Well if gravity is higher then the weight is more right? [07:50:24] yes, but that just means the atmosphere is deeper. [07:50:51] Real life Mars atmo does extend out quite a ways though [07:51:24] yep, because the lower gravity and compressability of the atmospheric fluid. [07:51:40] Hm [07:51:50] But anyway I'm not the one who made the mod [07:52:09] you still reach a point where the atmosphere doesn't have enough weight above it to reasonably compress. [07:52:43] and 1.9 Gs doesn't sound like enough to get into weirder states of matter. [07:53:22] lol If we're getting into that I don't think KSP is capable of simulating it anymore [07:53:39] Should just auto-destroy the craft like on gas giants [09:52:53] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [10:34:26] #KSPOfficial: mode change '+o Deddly' by ChanServ!ChanServ@services.esper.net [11:29:51] Whoever said you don't need all the ablator may have cost me this mission.

[12:17:10] Zup Fluburtur? [12:19:42] doing stuff [12:19:50] installing lights on a plane for night flying [12:21:41] and infra cam too? [12:22:18] nah [12:22:28] I think the camera on it already has good low light video [12:22:36] and I won't be flying fpv during the night anyways [12:23:30] https://cdn.discordapp.com/attachments/186186471202357249/431066258398773248/DSC_8633.JPG [12:24:01] left is red, right is green [12:24:29] back is white [12:24:44] and we didnt even get into the anti collision light and other strobes [12:24:46] not quite, port is red, starboard is green [12:25:06] no [12:25:09] everything is blue [12:25:14] lol [12:25:23] taniwha, well its hard for aircraft to fly backwards [12:25:24] anyways it is shaped like and arrow and there is only lights on the bottom [12:25:32] for some aircraft [12:25:37] Gasher[work]: easy to face backwards on an aircraft, though [12:25:42] some other aircraft are doing fine [12:25:54] eeh [12:25:57] ah right [12:31:45] I had a internet cut [12:36:37] Fluburtur: I was talking about the Youtube breaking :) [12:48:08] Airplanes standards are just Boat standards VASTLY extended [12:58:18] http://www.scp-wiki.net/scp-2258 [13:01:34] balloons?

While in& https://t.co/6Wt9fwy1Ia [14:59:05] time to try making tank tracks and wheels in CAD [14:59:52] many people hated humanity star because it was light pollution [14:59:56] very bright blinking stinhfg [15:00:11] "oh no a little light in the night sky" [15:00:19] time to call the ISS light pollution too [15:00:36] it was quite bright if you wanted to do some astronomy [15:00:48] it was the point [15:00:52] so peoples could see it [15:01:05] Fun fact: They didn't model anything. They just looked at other objects and said: An object in this orbit stays there for around 9 month. [15:15:56] that is in a way better than modelling, it is real data colletion [15:17:45] but the object in question may have been different from normal satellites and behaved differently [15:18:15] it was much much lighter [15:18:15] still, the electron rocket is cool [15:18:43] so basically empty inside, so an empty shell that has high drag for its mass [15:19:47] yep [15:20:05] high drag, low mass, get's down early. [15:25:47] that looks half decent https://cdn.discordapp.com/attachments/186186471202357249/431112119484809236/tracks.jpg [15:26:17] what, now you are building a tracked plane? [15:26:23] a tank [15:26:28] I want to make a ripsaw [15:26:44] but I did create a "tank" folder in my "planes" folder [15:26:51] Mining robots!

[15:28:12] You can stop them with 1 guy in a Pyro-GX? [15:28:55] only one guy suffers. who cares, meh [15:29:46] and the hostages, but those are flat anyway :9 [15:32:03] I want to make something like that https://youtu.be/9-9uzLBtMtY?t=15 [15:34:15] Come to think of it, what happened to the hostages after you "rescued" them? [15:34:27] and why were they 5 m tall? [15:35:10] it is the same question as what happened to the empty flasks in the original prince of persia after you drank from them [15:35:37] he doesnt throw them away, they just vanish. maybe puts them in his pockets, but so many? [15:44:16] now, how can I make a drive gear for those tracks [15:44:47] I guess if I put some sort of half circle over the track and corresponding grooves in the drive gear it can catch on those [15:44:54] with a hole for the drive pins [15:46:05] https://youtu.be/Xv20j8ChtRY?t=350 see? where does the flask go? [15:53:15] uh I need to find how to scale the drive wheel for the tracks [15:56:33] I think I can do that with some parametric stuff [15:57:03] wintergatan olive oil? [15:57:12] yes [15:57:51] at least make it apricot jam or something. i cant eat that [15:57:59] i cant eat olive oil [15:58:17] be nice to him he has never seen an olive before coming to france [15:58:32] i have and it is not my thing [15:59:26] I find olive oil to be rather nice in salads [16:00:13] https://www.picclickimg.com/d/l400/pict/253376721874_/Vintage-Packard-Bell-Model-PB434A-Computer.jpg - Just found an image of our first real computer. case looks exactly the same but not sure of the model.

In his marble machine video, what is this part at about 1:50 to 2:20 when he stops it and starts playing by hand? [16:04:34] What happens there? [16:04:50] the vibraphone? [16:05:21] on the left? [16:05:42] that is the part that makes the vibrato effect. and since the machine is not running, he has to drive it manually [16:05:51] I guess?

[17:42:37] (what's the EM drive doing? ;) [17:42:45] ve2dmn: ah, finally someone with culture. :D [17:42:48] unless you make a warp drive you need to eject stuff [17:42:53] or maybe photon drive [17:47:33] Mat2ch: the paperclip maximizer is not THAT obscure [17:48:24] ;tell scolar_visari today in beamed propulsion https://www.centauri-dreams.org/2018/04/04/procsima-wedding-two-beam-concepts/ [17:48:24] UmbralRaptor: I'll let scolar_visari know when I see them [17:51:21] that is also nice, because the ship can remain light [18:04:30] Imagine if you could directly use the Sun as a source of the beam [18:06:31] solar sail [18:06:42] actually works [18:06:47] yup [18:07:31] but more like https://what-if.xkcd.com/141/ [18:08:20] hehe die from twilight [18:15:20] Still one of my favourite xkcd quotes: "You would just stop being biology and start being physics." [18:15:34] hehe [18:15:38] we are always physics [18:16:08] unless you think biology is supernatural [18:17:48] https://what-if.xkcd.com/92/ [18:21:03] "You wouldn't die instantlyyou might survive for a few milliseconds or even seconds. That might not seem like much, but compared to the speed at which you'd die in other What If articles involving relativistic speeds, it's pretty long." [18:27:51] https://what-if.xkcd.com/imgs/a/147/yikes.png [18:35:46] I still need to make myself a 3d printed potato gun [18:36:03] A nuclear one? [18:36:20] nah I don't have enough nuclear materials yet [18:45:43] My brother has one. I think he said the range on that thing is like...half a mile [18:46:11] Action: APlayer hides in his nuclear bunker [18:47:27] that is impressive [18:48:28] that's 0.8KM for Flub [18:48:53] I wanted to make one with a 4 meters barrel made to shoot spark plugs above 400kph [18:49:18] because im sure a spark plug at that speed is an actual armor piercing projectile [18:49:30] Fluburtur: I would be scared of the thing blowing up in my face [18:49:51] shhhh [18:50:02] not shh, ssh :) [18:50:40] And I should mention that xkcd's 'what-if' is the ultimate Nerd Snipping [18:50:55] i am immune [18:50:58] they are too long [18:51:06] so i gave up on reading them [18:51:29] You don't know what you are missing.... literally [18:51:49] i read the first some of them [18:52:00] i like them [18:52:06] but it is a matter of optimization [18:52:25] I can do a TL;DR of most: "Boom!" [18:52:47] or black hole... whichever comes first [18:53:02] ve2dmn: I still think he's completely worng about burning things with moonlight [18:53:22] "This is, by far, the most destructive What-If scenario to date." [18:53:55] because the moon is not a black body emitter. it's reflecting light from the sun [18:54:09] Althego: Random quote to make you read xkcd: "The flash of light and heat would be so bright that if you were standing at the surface of the Sun, it would be brighter above you than below." [18:54:16] i read the comicsa [18:54:24] i have been doing so for more than a decade [18:54:35] What-if xkcd, I mean [18:54:42] no time for that [18:54:47] https://what-if.xkcd.com/145/ <-- this one is totally wrong [18:54:54] I like the comic that said 'The sun (actual scale)' [18:55:09] oren: I was wondering about that too [18:55:32] It does not satisfy my question of why the Moon is not considered as part of an "optical device" [19:00:28] APlayer: it is also wrong about the temperature on the surface of the moon. the moon's equator in broad daylight is 116 celsius which is more than enough to kill Buzz Aldrin [19:00:48] he was wearing a thermal protectiv garment for a fucking reason [19:01:16] Sorry, but please mind your language [19:01:33] also had an active cooling system [19:01:40] it's like wrong in four different ways [19:01:55] where the amount of sublimating ice was the real limiting factor of the moonwalks, not the amount of oxygen they had [19:02:03] But let's say the 116 deg C thing is nitpicking [19:02:28] The point of the article lies somewhere else [19:02:57] It tries to illustrate that the moon is not hot enough to start fires (under normal fire starting conditions, at least) [19:03:51] but the moon's light is not equal to its black body temperature (citation: rocks at 116 do not glow white) [19:04:27] Well, that's where things start getting interesting to me [19:04:58] Why is the Moon not considered a mirror in the same optical system that should focus light onto a point and start a fire? [19:05:08] considered to be a mirror* [19:05:12] #KSPOfficial: mode change '+o Deddly' by ChanServ!ChanServ@services.esper.net [19:06:37] I think randall is just wrong [19:07:00] Not sure [19:07:26] The beginning of the article explicitly says "It involves a lot of arguments that sound wrong but aren't, and generally takes you down a rabbit hole of optics." [19:08:44] And Randall sure is a pretty smart guy with lots of readers who would point out such blatant mistakes in his facts [19:09:04] There must be something we are missing [19:09:50] http://forums.xkcd.com/viewtopic.php?t=113444 [19:10:05] nah, people are calling him wrong on hsi won forums [19:11:09] https://www.reddit.com/r/xkcd/comments/451qis/whatif_145_fire_from_moonlight/czuqlfg/ [19:11:23] I could start a fire WITHOUT moonlight :D [19:13:59] oren, "The Moon's sunlit surface is a little over 100°C, so you can't focus moonlight to make something hotter than about 100°C. That's too cold to set most things on fire." [19:14:13] he does say that about the temperature on the moon [19:15:57] trying to fix an old hard drive from my other computer, maybe I can use the remaining life on it. https://i.gyazo.com/57a87c6efba4ea29cb1bacf313e37575.png [19:17:09] Draconiator: that Hardware ECC recovered is a bit high.... otherwise it looks fine [19:17:38] https://www.reddit.com/r/xkcd/comments/451qis/whatif_145_fire_from_moonlight/czvr6rk/ [19:19:45] I feel like there's an easier approach to this problem [19:19:59] The practical one? [19:20:21] well, you *could* build a giant lens and see if you can set things on fire with the moon [19:20:50] That how Oxygen was discovered... (except with sunlight) [19:21:54] Alright, this convinces me: https://www.reddit.com/r/xkcd/comments/451qis/whatif_145_fire_from_moonlight/czuq8hj/ [19:21:57] but I think you can just measure the moon's apparent brightness and figure out how much energy you're getting from it; shouldn't that tell you whether you have enough incident energy to start fires without even worrying about the exact properties of the moon? [19:26:25] And I should (again) mention that xkcd's 'what-if' is the ultimate Nerd Snipping [19:27:16] haha [19:36:52] Sons and daughters of Kerbin: Wild Visari used TAIL WHIP! [19:38:01] . . . But it had no effect on BLACK HOLE SWARM https://phys.org/news/2018-04-tens-thousands-black-holes-milky.html [19:38:13] Action: Scolar_Visari curses Nature's paywall. [19:39:41] Black hole swarm, won't you come... [19:40:01] ve2dmn: Sadly, they're affected with SLEEP. [19:40:23] But for some new work that doesn't have a paywall restriction, I present to you Han et. freaking al., "OGLE-2017-BLG-0482Lb: A Microlensing Super-Earth Orbiting a Low-mass Host Star" Earth and Planetary Astrophysics 2018 https://arxiv.org/abs/1803.10830 [19:44:51] Because formatting scientific notations is a pain in the final end of the digestive tract, I'll paraphrase this article: Observed planet with unreasonably long name measures in at around 9 Earth masses (!) and orbits a star with around 1/5th the mass of the Sun. [19:44:51] Scolar_Visari: I was reference an old song from 25 years old [19:46:39] ve2dmn: I was actually thinking of Ron Ormond's, "If Footmen Tire You, What Will Horses Do", as it ends with a one Estus Pirkle quasi-rhetorically asking the audience, "Won't you come?" multiple times in a perturbing manner. [19:46:54] https://www.youtube.com/watch?v=3mbBbFH9fAg [19:46:54] YouTube - Soundgarden - Black Hole Sun [19:47:22] I'm not sure the stellar mass black holes would be welcome at his congregation.
