In many series (Elder scrolls for example) they have a huge moon. It is rare though when they explain how it can be larger. There are only two choices both of which couldn't work; One is to brin...
I understand that Antarctica plays a large role in driving ocean currents and thus the climate of the planet. However, I'm curious what the world would be like if there was no Antarctic landmass at...
The idea is- as the moon is passing over, the pull of Earth's gravity on immediate area surrounding the spacecraft somehow temporarily cancelled out (still working on the how) and the craft falls t...
So for the purposes of this question, the following items are already determined by our world: The humans and human society are in very beginning of an Industrial Revolution almost identical to o...
Consider yourself a decision maker for a fledgling space infrastructure project. You've been tasked with establishing the first few extraterrestrial colonies for your species. What aspects of the...
There exist numerous theories on why the Moon lacks a layer of air if any, however the main culprits are gravity and the lack of Geo-dynamo simply put the Moon does not have the necessary mass nor ...
A moon is, fundamentally, a rock that's caught in the gravitational field of a bigger rock (a planet) and drawn into an orbit. Some of Saturn's moons, for example, are speculated to be debris from...
Here on the stack exchange we talk about dragons... a lot. We have discussed all the factors that would allow dragons to exist and yet, there is a question we have not asked. What evolutionary pres...
Here on earth, the moon is this big white thing that lights the world and hangs in the sky. Every culture on the Earth has incorporated the moon into some of their legends. Sometimes as a woman, so...
Suppose you have a 2+1 dimensional universe where the physics of that universe (we'll assume that the physics causes something similar to chemistry and that there is no gravity, but there is specia...
The older man looked at the younger one. He took a deep breath and began to tell his tale, just like he was told before when he himself was that young. I've been here way longer than you, let m...
All multi-cellular life as we know it is composed or eukarotic cells -- cells with a nucleus. Some single-celled organisms are eukarotic, some are prokaryotic (cells without a nucleus, such as bact...
The US Government, and eventually the UN and all nation-states around the world, have realized they are broadcasting their existence to potential enemy civilizations in the nearby galaxy (at least ...
We have all heard about the idea of space elevators, a cable so long that it literally reaches into outer space, to be used for launching payloads cheaply into Earth and interplanetary orbits. Howe...
I have got a big rotating space station (radius is 5 km and length is 30 km) which provides its occupants the luxury of full terran gravity and atmosphere. The biggest part of the cylinder's inner ...
I have a group that's building a moon colony. The final end goal is a self-sufficient colony of at least 1 million humans. They have access to one million metric tons of lift per week at nominal ...
I am an immortal, megalomaniacal supervillain with unlimited resources and patience. I want to slowly eliminate the Earth's axial tilt so that its equatorial plane is coplanar with its orbital pla...
We like the moon. It's close, you can see your home from there, low gravity well, so you get easy mass drivers to orbit for fleshing out your spacer economy, plus you can do fun things in pools. ...
A group of scientists has been slaving away largely in obscurity for two decades, with very few publishable results. Suddenly, one of them has an epiphany, which turns out to be instrumental to ena...
I was thinking of a sci-fi story where a large population of human beings (let's say anywhere between hundreds and millions) live on a planet with robot guardians. But after a certain amount of tim...
Let's say my terrestrial planet has a stable circumbinary orbit around two suns similar to the Kepler-47 system, in the habitable zone, with an orbit similar to Kepler-47c. The challenge here is th...
At a crucial point in the development of human civilization, there is a split in the timeline: one where FTL travel is facilitated by jump-drives/wormholes, and another with superluminal speeds (St...
Question: Are there are any serious biological or evolutionary plausibility issues with separating the energy storage/production function from the production of structural/regulatory biomass? Back...
I am mad scientist and I captured Average Joe, who is not average only in one remark: He is person not to be missed (I double checked). Otherwise he is healthy male, around 30 years old, with no fo...
I'm working with a city that has cut itself off from the surrounding area. There may be as many as 10,000 people within it, or as few as 1000. I'm trying to be as realistic as possible. How long...
