  1. Then the glaciers start melting. On the other hand, should they be afraid of the ocean level?
  2. Would sound funny before the KSP2 release... Any step in hardware means two steps in the problems complexity. In any case, one can't preset the whole universe in the emulation, until the emulation asymptotically reaches the universe complexity level. This means that the only emulation having enough level of presets to indistinguishably emulate the universe is the universe, and the ultimate simulation is what the reality is. No people reported that they can see only polygons in the microscope, if proper experiment conditions had been provided. Every positive makes the negative less probable.
  3. If take a microscope and watch a drop of dirty water, you'll see microbes. If take Skyrim with Hi-Res mods, you will see either polygons, or internal space of the object. Because in the world around the bacteria, the atoms, the quarks, etc. have been existed before you took the microscope, while the hardware to run Skyrim has limited capabilities, so the designer is limited in detalization. No bacteria, no atoms, only polygons, until somebody adds a microbe mod. The universe contains a full set of possible details from scratch, and the FPS doesn't fall, thanks to its parallel architecture. So, while originally you don't know if there is a simulation or a reality around, with every next level of detalization the probability of the latter is growing. Asymptotically, you come to the holographic universe, where all possible states have already been rendered, thus it provides infinite FPS.
  4. Then the generation algorithm must be defined. I.e. in any case the simulation has limited depth of prepared emulation levels. Only the universe-wide presets can provide a model for any level without preparation. And this unique universe-wide simulation is called reality.
  5. First a mathematical description of the physical model should be created, to let them have what to show. Otherwise the next level will be either empty, or random and thus not related to the previous and the next next level. The reality is the ultimate set of possible states of all existing physical models. It's the ultimate level of simulation. But they can't simulate what's inside the proton, until you define a mathematical model for that. Yes. Limitedly. They can't simulate zillions of atoms, the planet consist of. The reality can. Because its hardware is the whole universe, and the same universe is a code for that. No Matrix would emulate bacteria and quarks, when the purpose is to let them live in a virtual life. Because its hardware resources are limited.
  6. To simulate something, it should first have a model what to simulate. And on the deeper level... And on the deeper level... And on the deeper level... And on the deeper level... And on the deeper level... To simulate any level, you should have models of objects on any level. Thta's what is the reality. Any other simulation is limited with some final level of detalization. Ask a jinn to create a working clock. Will it be a mechanism or a medal with painted dial? So, while you can get deeper and deeper into any thing, you can't say for sure that it is a simulation. And by default, it's the reality.
  7. Take a hammer and hit your watch/clock. If this is a simulation, you will see nothing but polygons. The only simulation, able to get deeper and deeper is called "reality". In the Odyssey'2001 last chapter, there is a scene where he is living in a room constructed by the aliens, who had no idea about the books, so the books are actually cans with powder (?).
  8. 1761 * 3600 * 9.81 * 9 / (3*108) ~= 2 light speeds in total. It's a superluminal launch pipe.
  9. https://en.wikipedia.org/wiki/Kolobok The classic Russian legend tells about Kolobok ("The Round-Sided One"), who was a sapient, human-faced, spherical bread, made out of remains of grain in the stock, by the couple of elders. It can't be just a coincidence that Kolobok has a hydrostatic equilibrium shape. Obviously, it was baked in zero-g, so the oven, used by them, was somehow related to the further orbital station experiments. If send Kolobok enough far, to the hypothetical Oort cloud, it could be a planet.
  10. Now they know, which god's damnation they had happily evaded from, thanks to the editor good manners.
  11. Floor 4523: A friendzone. Only friends around.
  12. Oh hey, join the club, I turned 53 back in September! More than cards in a poker pack. Two jokers began. Then will be the turn of the Major Arcana.
  13. To not found colonies on the airless bodies. Also, "airless" == "low gravity", what is also not healthy.

  15. Using the magnetic sail used as a magnetic chute as a magnetic sail. Returning to the interstellar Orion design described above. So, the basic propulsion unit is: a wireframe magnetic reflector ~300 m in diameter, used as a pusher plate. It's hanged in magnetic suspension. On every nuke it's powered with induced electric current, reflects the tungsten plasma back, and pushes the ship forward by recoil. Then slides back and repeats. Probably, it also rotates somehow. The fission stage of the nuke is less-than-weapon-grade U-233 (made out of Th) without chemicals, unable to explode on its own, useless without additional enrichment for random people who found it. It gets radially compressed by the ring of X-ray beams from X-ray emitters (harder than the chemicals could do), gets supercritical, explodes, heats and compresses the secondary fusion stage of the nuke, which in turn heats and compresses the inert third stage with the tungsten membrane. After the acceleration, the ship turns with nozzle forward, and keeps flying so. The X-ray emitters become anti-meteorite battery, which evaporates everything on the way, turning it into ionized dust or plasma, reflected by the magnetic nozzle. The nukes are classically packed into lateral columns of cola-drums, which get jettisonned on getting empty. On approach to the destination star the propulsion unit extends several (read - six) long trusses, which are originally folded between the drum columns. The trusses, electrically connected to the magnetic nozzle, form a wireframe antenna-like supernozzle 300*2 + 300 + 300*2 = 1 500 m in diameter, which is the magnetic sail. The incoming proton wind from the star generates electricity in the external part of the supernozzle (formed by the trusses), which pushes the protons back by the central part of the nozzle, i.e. by what was reflecting the plasma. It decelerates the ship from interstellar speed down to the hyperbolic interplanetary speed, aiming at the tops of the star protuberances. On close approach, i.e. at the Oberth maneuver altitude above the star surface, it enables additional electric circuits, placed on the same wireframe rose, using the whole thing as an electric chute, which interacts with the star magnetosphere and slows the ship down to the high-elliptic speed, sending it to local Jupiter. In the local Jupiter it again slows down and redirects the ship to the local Earth, and finally it gets into orbit, uses the supernozzle as a radioantenna, and then as a wireframe structure: to attach radiators or solar panels, to dry the clothes, etc. *** But of course we could use it also for acceleration. The problem is, that it doesn't interact with laser beams, only with proton beams. So, the lasers are useless. We must send a proton beam from the place with cheap protons and energy, i.e. from the Sun or Jupiter proximity. But the proton beam will quickly dissipate, due to the electrostatic distraction. So, the beam must be of neutral hydrogen, turning into protons on approach to the ship. Say, the hydrogen beam crashes into a cloud of something dense, behind the ship, gets ionized, splashes against the supernozzle and pushes the ship. So, a hydrogen scoop at Jupiter; a powerplant somewhere at Io, or a ring of near-solar light scoops forming a UV laser to the Jupiter; the acceleration emitter at the Jupiter orbit uses the laser beam from Io or Sun for power, ionizes the hydrogen, collected by the scoop, accelerates these protons, neutralizes them in the recombination chamber, and emits a fast beam of neutral hydrogen to the ship; instead of the nukes, cans of something dense and hydrogen-rich (plastic?); the same X-ray emitters to evaporate the can to form the small cloud to stop the incoming short beam of hydrogen. Thus, the only difference is the cans of something instead of the nukes, in same drums. So, it will be a Unified Interstellar Tug with two modes: active (drums of nukes) and passive (drums of cans). Both modes are pulse. The active mode obviously, the passive mode is pulse to let the next can fly out, get heated by X-ray, and evaporate. So, the hydrogen beam emitter is also pulse, synchronized with the currect precise position of the ship. The hydrogen beam must come exactly on the cloud creation, and finish exactly on its dissipation. Thus the emitter beam has constant duration of the beam, but precisely varying shot moment. As a mis-hit can damage the ship, maybe the active mode is for crewed or uncrewed pioneer crafts, while the passive mode is for regular cargo sending.
  16. BanYou Tapestry bans for Ye Olde Englishe.
  17. https://historynewsnetwork.org/article/181681 800 km in diameter = 500 000 km2 = 0.5 mln km2. Earth land area = 140+ mln km2. Say, a half of the land is deserts and wastelands. So, you need ~150 x 10 Gt to eliminate the terrestrial life. Say, it's based on LiD and uses 238U for casing. Then it's ~50 000 t heavy in total, Together with propulsion and other, 200 000 t. Say, average density is ~1 t/m3, like for the known meganukes. Total volume ~200 000 m3. Centrifugal artificial gravity habitat safe radius = 100..200 m. A typical crewed ark cross-section area = pi * (100..200)2 = 30..120 * 103 m2. 200 000 / (30..120 * 103) ~ several meter length. So, the 150 x 10 Gt fit the mass-dimensional capability of a typical space ark (i.e. an interstellar genetration ship, or a mass rescue ship at the Earth, or a near-Mars orbital habitat), with a hundred-up-to-thousands crew and a fridge+incubator facility with frozen ravioli colonists. Just it is a ring of 10 Gt warheads instead of the artificial gravity ring. And their propulsion unit is absolutely the same. So, there is no problem to send three such ships in advance, before sending the colonists. It comes to the star of interest, calculates intervals of arrival (to let the warheads keep the safe distance from each other, and to let the planet of interest rotate and bring next hit point under the next warhead hit), and releases the warheads, without braking. The no-brake scheme is important. If the local biosphere is equipped with defense systems, it's much harder to intercept the incoming warheads, which are moving at the near-interstellar speed. After the 150 x 10 Gt near-space explosions, the landmass is totally burnt, so the local lifeforms are eliminated, the local ecological chains are broken, the local biosphere starts collapsing. Next, another crewless set of ships arrives and spreads the terrestrial grass, rodents, rabbits, cats, and wolves (consult with Australians, what they don't let to import, it's exactly what you should send). They eliminate the remains of the local biosphere, and form the Tier 1 of the terraforming. Several decades later, the fleet of colonial arks begins arriving, occupying the planet, and populating it with the correct set of lifeforms. By repeating this scheme on every next star system, you will successfully perform the interstellar extinction of the previous sapient species, and terraform entire galaxy. *** In case if somebody thinks, that it's a joke, no. It's absolutely the traditional historical way, how the things are being done. https://en.wikipedia.org/wiki/Slash-and-burn https://ru-m-wikipedia-org.translate.goog/wiki/Подсечно-огневое_земледелие?_x_tr_sl=ru&_x_tr_tl=en&_x_tr_hl=ru&_x_tr_pto=wapp "Slavic colonists are developing the eco-village on the burnt surface of Epsilon Eridani 5". (You can see the already terraformed areas at the background)
  18. You may need a standby orbit to wait for a good lunar weather for landing. Stormy lunar seas, clouds, solar winds, sometimes tornados.
  19. The sentenced to death term. So, they know some secret sentence, which kills the prisoner when they pronounce it. P.S. It looks so plain, that I now even doubt, if it's not a granny's joke in the original book...
