What would it take for humans to survive on mars, without shelters, akin to the Martian, in terms of genetic engineering? Is it even remotely viable, or would some mechanical assistance (oxygen tan...
Background I just read this question about how to get a planet to have one hemisphere with tropical climate and one with polar climate. The (not yet accepted) answer with the highest score recomm...
I have read many posts about planets in perpetual sunset or twilight. Tidal locking, perpetual sunset at the poles of a planet with zero axis tilt, and so on. Great information by the way. This que...
In a game scenario I am developing, one option for a fleet to infiltrate an enemy is to use ftl to "hard burn" through a black hole's event horizon. Their ftl drives use a "warp bubble" principle t...
In my world, ten is an important number that shows up frequently. In the solar system my world belongs to, there are ten other planets beside it, and there are ten months in a year. I know next t...
I'm conceiving of a world where humans can readily terraform worlds that were once considered "dead" due to the planet's magnetic field being long gone. In such a situation, what could humans do t...
I have a (digitigrade) quadrupedal alien creature with one of it's front limbs having a longer metatarsals, I'm trying to visualise how it would walk with this deformity for an animation. I'm havi...
In which wilderness area on modern-day Earth would it be easiest for a lone human to survive year-round? What resources are available there and what tools and skills would be necessary? What is t...
I was wondering, if a planet in similar size and mass to earth would have, from its creation, been spinning at this hypothetical planet speed limit (with it somehow staying in once piece) could lif...
Human sight uses about 500 megapixels. Now, imagine someone who uses more than 500 megapixels (with the same width), I assume that he would see things more accurately. So my question is : - how man...
I would like a planet that's a tropical paradise on one side but covered in ice and glaciers on the opposite side, whether it be the Southern-Northern or the Western-Eastern hemisphere. I know it...
Properly ventilating a deep mine is a significant engineering challenge. Ergo, you don't want to be carrying around torches that use up some of your precious breathing oxygen if you don't absolutel...
I've been trying to answer this question for a premise involving a cyborg being out of touch with modern civilization for a prolonged period of time, and the roadblock I keep hitting is that counte...
For my question, I was wondering the idea of a creature that needed to be visually seen by Humans or else, if no sight on it by a human being has been made then it can only last for 24 Hours. I w...
If you look at one of my previous questions, I ask about a tidally locked planet and it has come to my understanding that such a planet would be under a lot of radiation from the sun. So I'm curiou...
Normally when conducting DNA testing, I presume techniques are utilized to ensure you're just testing one individual's DNA from a sample, even if it is possible that sample was contaminated one way...
Over several hundred years, a tide-locked, but otherwise Earth-like, planet orbiting a red dwarf is terraformed. The terminator is a very habitable zone, in terms of temperature, atmosphere, etc. C...
We've seen it throughout media before, a crazy mutation that creates zombies, rabid people, giant spiders, etc. I'm spot checking how crazy I can get with this short story I'm writing about a bacte...
The Akashic Records are a catalog of all events, thoughts and feelings that have happened on Earth. Supposedly its stored on the etheric plane. I'd like to have this information existing in the t...
Assume that an Alcubierre drive is feasible. In fact, assume that one has been built. A superluminal starship can propel itself through space by distorting space in front of it and behind it. Howev...
The whomping willow is a fictional tree from the Harry Potter series of books. It is a magic willow that can move its branches to punch people who come close to it. Small animals such as cats an...
Consider a planet $P$ of radius $r$ larger than Earth, whose mass is $r^3$. By the square"“cube law, this planet will have the same density as the Earth... assuming that the gravitational compressi...
I understand that some non human animals build structures that they innately know how to build, such as how birds innately know how to build nests, and spiders innately know how to make webs, and b...
I am currently working in a "fantasy" world without any kind of magic and I thought of a race with different skeleton color (blackish in particular but I want to know in general). I am not well ver...
Given an arbitrarily long time to do so, what is the maximum depth too which a dwarven civilization could practically extend their mines / cities? And what would be the final limiting factor preven...
