The mass of an economically feasible non-microscopic traversable wormhole Background In my hard sci-fi settings, there is an advanced Type II Civilization, that are progressing toward Type III Civilization (yes, I am referring to Kardashev Scale). They are sprawling across the galaxy with relativistic ships, generational ships, and perhaps counless unmanned Von Neumann pr... (more) |

What would be different if a person has broader visual spectrum than normal What would be differently perceived from a person with broader visual spectrum than normal? So I've seen this question, especially the accepted answer, and it certainly is not what I'm looking for. The question asks for a man with the eyes of martial eagle. The answer, likewise, considers the acui... (more) |

Thermal Energy Recycling from Daylight Operation to Power Night Time Operation of Volatile Computer Storage Is it possible to use thermal byproduct of daylight operation to power night time operation of volatile computer storage? In my setting, a moon-like moon with almost no atmosphere has one of its sides (the far side) populated with nodes powered with sunlight (solar flux of said planet is around $124... (more) |

How would I calculate how much of Venus would be covered in water if 8.8E16 m^3 was added to its surface? If $8.8 \times 10^{16} m^3$ of water volume is added to the surface of Venus, how would I calculate how much of Venus would be covered in water? The land of Venus has its topographical features with plains, valleys, high lands, etc, therefore water would not be distributed evenly across the surface.... (more) |

What is the best way to classify Intelligence in a world full of various Intellects? [This question was posted on Sandbox] Abstracts In a world where there are different kinds of intelligence, I am in need to assign classes to each mind encountered. The measurement doesn't have to (and is encouraged to not) be human centric in comparison, so human intelligence may have non-human ce... (more) |

Calculating Time Dilation Effects on Relativistic Accelerations Prologue In my current worldbuilding project, I decided to put a ban for faster than lightspeed travel, and decided that most space flights be done in slower than lightspeed travels. Assuming efficient engines had been invented in this universe (say, some sort of 80% to 90% energy efficiency), and a... (more) |

How could earth civilizations send 2000+ humans to Venus in six years? Current Settings Humanity could no longer access earth for some reason (it could be anything from alien invasion, third world war, ecological disaster, etc) starting at 2028, and they know about this as early as 2022. They gather resources and decided to flees up from earth. Some party looks to the ... (more) |

A spacecraft the size of Apollo 11's lunar module, composed of antimatter, around a normal star After writing this question, I came up with a new question. Consideration The considerations are mostly similar to the linked question (reading it is highly encouraged, as I am trying to post as little redundancy as possible) The ship in question is comparable to Apollo 11 lunar module The distanc...

What is required to make watery, blue-white colored jovian planet at habitable zone of a star Background In my story, HD 28185 star system harbors life. One of them is a jovian HD 28185 d (Subralis), located around 1AU of this sun-like star. In-universe, Subralis is approximately 132,000 kilometers in diameters with around six times the mass of jupiter. Its atmosphere should contains water-m... (more) |

Apparent feature of a jovian planet approximately 1AU from an earthlike planet Background In my story, HD 28185 star system harbors life. One of them is an earthlike planet called Aucafidus, located at L4 of HD 28185 d (Subralis). In-universe, Subralis is white-blue in colors with white-ish clouds due to water vapors on its atmosphere, its diameters is approximately 420,000 ki... (more) |

How should I introduce heavier elements on this world? Based on this question I asked a while ago, I would like to know how to safely introduce new heavier elements to the world by asteroids without wiping the entire life and even keeps handy quantity of civilization to stay alive and prosper. Assuming the quantity that would be delivered is roughly sim... (more) |

Humanoid evolution Background We all know that our species evolve during and after the last ice age, (or is it sufficient to say that they evolve at the end of ice age?). A. Initial Condition Suppose I had another planet with similar ancestor of human-and-apes species, but they evolve on the beginning of ice age (in... (more) |

Antimatter Storage Is it possible to contain similarly charged particles in a magnetic field or traps, in generally large scale (say, all of them have positive charge), and could be utilized as power reserves quite easily? Isn't it be easier to implement, than to put antimatters (say, antihydrogens) in a magnetic stor... (more) |

What would be the most likely colour of leaves on plants on a planet orbiting a red dwarf? Imagine a red dwarf star orbited by a considerably Earth-sized planet in the star's habitable zone. Assuming the planet has a sufficiently powerful magnetic field to protect its surface from the star's radiation, and life thrives on the world, what would be the most efficient pigment for plants on th...

Nanobots Ecosystem, is it possible? The Settings: A pod of nanobots stranded on earth-like barren planet orbiting sun-like star. Assume no life form has formed on the planet, and nanobots popuate the planet. Could they evolve complex ecology (techno-sytem in place of ecosystem) where plant-like and zoo-like species composed entirely ... (more) |

Planetary Habitability at twelve to seven billion years ago Following this question, I had additional question of habitability. Assuming that life could exist on planet formed roughly twelve billion years ago, allowing complex life to exist as of seven billion years ago, what would be the most plausible explanation of how they survived from: Given the muc...

Cosmic Background Radiation in the past I have a story where a species of the very first (literally first) carbon-based humanoid life (surprise!) that happen to emerge roughly seven billion years ago (their home system were formed twelve billion years ago). Assuming that it's possible that a star with age of around twelve billion years has... (more) |
