Could the equator of a world be a closed-time like loop? Most works of fiction have quite imaginative views of time travel. Mighty machines that teleport in time instead of space. Gaping portals in space that take you to another time. Mystical beings with a special power to move freely in time, sometimes taking a mortal companion. Physicists, on the other... (more) |

How would crystals be different in hyperbolic space? Let's say our world is set in a hyperbolic space with a curvature K of −1 per 9 square meters. How would crystals be different than those in our world (assuming that the atoms are the same as the ones in our universe)? One thing to note that on small scales, hyperbolic space is approximately euclid... (more) |

If humans were biologically immortal, but had an average lifespan of 100 years, what would the distribution of ages be? Let's say that humans were biologically immortal. Once they reach adulthood, they effectively stop aging. Due to disease though, the average lifespan is 100 years. (In practice, your access to healthcare would have a huge effect on your lifespan, but we'll ignore that for the purpose of this question... (more) |

Scientific/biological basis of someone with unlimited willpower? Meet Greg. Greg was born with pretty average genetics. It seems like he was destined to have average intelligence, average strength, and be average at everything. There was one particularly though: he has unlimited willpower. Willpower is the ability to resist short-term temptations in order to meet... (more) |

Space elevator into a blackhole. Possible? Inspired by Spaceship orbiting a black hole under the event horizon - a prison where no one escapes, I was wondering if it is possible to make a space elevator that goes down into a black hole. In particular, I imagine it would have the following parts: The space prison, where the prisoners can pl... (more) |

What if a traversable wormhole hits the earth? So, I the question of what if a black hole hits the earth has been asked to death by various people, but what if the somewhat tamer wormhole hits the Earth? In particular, we'll say that one mouth is floating somewhere in free space, and the other falls into Earth's gravity well. The radius of the m... (more) |

How would computer monitors work if we could sense the frequency of light? Human's abilities to perceive light is quite limited. Essentially, we have three type of light sensors that each give a linear signal, and if two different light sources give the same signals they will look the same. This is convenient for monitor makers though, since then computer monitors do not to... (more) |

How would a superhero who needs to fall asleep to use his powers fall asleep during battle? The Dreamer (a.k.a. The Sleepy Psychic by his teammates and enemies alike) has telepathic powers. The problem is that, while extremely useful, he can only use them whilst sleeping. My question is, how does he fall asleep and stay asleep during battle? Notes: He specifically needs to enter and stay... (more) |

At what scale would negative curvature be noticeable (and a nuisance to the flat space society)? After playing some HyperRogue, I got interested in the use of hyperbolic geometry in WorldBuilding, in particular how an area grows exponentially with respect to its radius. Let's say that the universe is a hyperbolic space. The world itself is a disc with a radius of 30 miles and an area with 196.9... (more) |

Can you just wait out the heat death of the universe? Okay, so the heat death of the universe is approaching. You can't stop it. You can't dodge it. What do you do? You wait it out. According to wikipedia, about $10^{{10}^{56}}$ years after the heat death of the universe, random quantum fluctuations will start another. Therefore, it would seem that it... (more) |

My program designed to be resistant to malware and DOS attacks isn't letting me turn it off. What do I do? So as an experiment, I took a bunch of machine learning algorithms (neural nets, genetic programming, traditional optimization, etc ...) and connected them in a mess of reinforcing loops, along with of my own algorithms. I'm pretty sure it's Turing complete, and could in theory develop any algorithm,... (more) |

What kind of human music do badger-folk like? Okay, so now that we've established that the badger folk (or Melinae sapien, if you want to be politically correct) are trading their ore to the humans for cat food. Now we need to determine what kind of culture exchange they'll have. To look at one particular issue, what kind of human music would ... (more) |

Is moonvertising feasible? As the legend goes, Coca-Cola was planning on shooting lasers at the moon to project their logo. Unfortunately, the FFA said no (they didn't want planes to be blinded). I haven't been able to confirm or deny this specific legend. My question though, is it feasible? Could you project a logo on the mo... (more) |

How would radical vegans/animal rights activists kill all the animals (to prevent them from being eaten)? This is a terrible planet for animals to live on, with all the humans around. Someone should just put all of them down. There is a group of radical vegans/animal rights activists that want to kill all animals. Specifically: They want to do this with the minimum power and influence possible. You ... (more) |

What would a space elevator on the moon be made out of? Okay, so some space miners fly into space to get Helium-3, and then fly it back to earth to sell to non-space people. Flying into and off the earth is rather expensive, so they want to simply take an elevator into space, but they can't find anything big enough to build it off. Flying into and off the... (more) |

Is it practical to build dirt scrapers instead of skyscrapers? Buildings are often build on the ground into the sky. Would it be conceivable if instead, we build down into the ground instead? We wouldn't have to worry about wind then. I think we could go farther down than up. Could a world have this? (more) |

Stealth in Space: How realistic is it? This has been considered other places on the net, but I thought it would be good for the hard-science challenge, since it is often an example of the subtle difference between soft and hard science. Okay, so you have your spacey ship in outer space. Then it is reported that space pirates have come to... (more) |

How many entities would a post-singularity A.I. in a world recognize itself as? So we make code for an A.I., and it makes better code, which makes better code, which makes better code, etc... ad infinitum. I'm not going to specify its goal. Maybe it's Robot Overlord Green. Maybe it's a paperclip maximizer. Maybe it's an oracle. Maybe it's just trying to find the true meaning of ... (more) |

What would self-repairing armor be made of? My question is, how can, say, a spacecraft have self repairing armor? It works using three layers: Delicate computers and people inside, armor repair system surrounding that, and then the armor itself. When the armor is damaged, the repair system excretes new armor. It sort of like when you get a scr... (more) |

How much life could our galaxy support? Okay, so we are figuring out, that at least for how we are running things now, our Earth can fit about 10 billion people. We can probably raise if your economy distributed resources more efficiently, but their is another route, SPACE! Anyway, so we get really efficient at going into space. My ques... (more) |

What would the economic impact of the ability to transmute lead into gold? Okay, my first trial run, How would humans and society react to a superhero existing and saving the earth?, of social sciences with hard-science is looking some what sickly at the moment (maybe someone is preparing an answer, but it is taking a while), so maybe I will chose a more mathy social scienc...

How would humans adapt their language in response to moving through time at different rates relative each other? Okay, so humans are finally transitioning to a space-colonial society. We sent ships out, colonize worlds, etc... We aren't really in the business of sending multigenerational ships. Instead we use time dilation. We generally only go somewhere when we can get there within a year of subjective time (a... (more) |

Could there be an atmosphere in which I could both be alive and float? There an atmospheres in which I can live, like Earth's. There are atmospheres in which I can float, like if it were a really heavy gas. Is there some atmospheric composition where I could both be alive and float, unaided? By be alive, I mean I could survive until I run out of food or water. By float... (more) |
