Okay, so I'm an engineer who's been tasked with transforming Mars. I don't need to make it perfect for people to be able to walk around free with no life support. But I do need to make life, espe...
Imagine that all men in the world became infertile right now. (This would apply also to all new born boys for as long as no cure was found.) How much time would humanity have to find a cure (or li...
In the story I'm building, a 3rd atomic bomb (same spec as Fat Man) was created for use on Japan - and dropped. However, for whatever reason, the 3rd bomb never detonated - impacted the ground and...
Thanks for all the comments and I've re-edited the question: All nature settings(radius of planet, etc) are similar to the real world earth except the continent layout. I used Mogensen Planet Ge...
In a previous question I asked how Mutually Assured Destruction could be made not assured. Most of the highly rated answers focused on political methods, but one answer raised the possibility that ...
Background A 100 years in the future Mars has been colonized, new settlers and resources arrive from earth every 26 months (when the planetary orbit lines up best) by first taking the space elevat...
Consider a universe in which leptons & quarks (every fundamental particle that possesses electric charge) all have twins with magnetic monopole charge instead, resulting in two parallel kinds o...
(Please note that this question is the sandbox version and the replacement of the original question) I have been wondering about how humans require facial muscles in order to be able to produce sp...
The Perspective: My story is told from the perspective of the simulated AI. In other words, The AI's world is influenced by the reason the developers chose to use a world-spanning war to test the s...
It has been said that one of the inspirations of the Cyclops of Greek mythology was from a skull of a dwarf elephant. Being twice the size of a human, people interpreted the nasal cavity (for the t...
I'm designing an alien race that in structure to humans. One exception is that they have long muscular tails. I remembered while I was designing them, the reason why humans have no tails is becau...
The premise of my story is somewhat similar to Jurassic Park in that a creature needs to be replicated from very little remaining organic matter. In this case, though, the relevant material is no...
I'm trying to design a humanoid or anthropomorphic organism that would be classified as a plant. The main argument people mention is that it wouldn't be able to produce enough energy to survive. I'...
Let's say a genetically engineered organism (as large as a whale), capable of swimming and breathing underwater, have an EMP field as a form of defense against man-made watercraft like warships and...
I have a slug that I need to kidnap. Not an ordinary garden slug; this slug is special. This slug's slime is violently reactive with the atmosphere on my planet, and explodes into flame on contact ...
Is it possible, with modern, or easily foreseeable technology, to build a compact digital data storage device that cannot be erased without removing the data store? The storage in question to be us...
Could a moon or planet with otherwise no atmosphere maintain gas pockets in sufficiently deep craters, and could it be habitable by humans without pressure or space suits? I found this similar que...
I'm writing a JRPG-inspired novel set on a planet with 1.7 Earth masses and 1.4 Gs, but is it possible for life to even develop on such a high-gravity planet in the first place? I tried scouring th...
My world has multiple layers of floating islands, which by itself causes a lot of climatic-involved problems for me to sort out. That being said I stomped into a very simple yet important factor to...
In Warlords I envisioned the "outermost colonies" around Neptune and Uranus to be a political faction of their own. Separate from the inner planets (Hegemony) and the Jovian and Saturnian leagues. ...
I'd like my world to have humanoid protagonists, while still reinforcing that they are ultimately not human, but have simply evolved in a similar way due to convergent evolution. To provide a const...
My world is very earthlike and I am looking to create a bird that primarily eats bone marrow. I wanted my bird to crack the bones of the carcasses to eat the marrow inside. What would the ideal bea...
I have a town, the capital of an empire. It covers 560 Hectares. What kind of natural barrier conforms to the following requirements: Is both heavily defensible and does not hinder trade all too...
So many millions of years ago their was a lobe finned lung fish named tiktaalik that led to the evolution of all tetrapods and the diversity they hold today. And I wanna do that again, but instead ...
So, I'm developing a world for my fantasy setting, but I thought it'd be neat if this particular world had a nebula visible in its night sky. (So, it might not be a nebula like the kind we have in...
