NASA received a telegram from the direction of Proxima Centauri stating that the abominable snowman are coming for a visit and they expect snow to fall everywhere even along the equator. They also ...
In a distant future world, people going to cinemas will not just see movies but 'experience' them. Spectators will be a part of the cast with the help of immersive virtual reality. How would these ...
Context NASA commissioned some awesome, vintage-style prints a while back advertising the colonization of Mars. Three of them stood out to me because they depicted colonization of the moons of ...
If a sentient supercomputer was created as a weapon of mass destruction, and it wants to consume humans for their flesh, why would it do that? I know this might seem too far-fetched, but if there'...
What I am proposing is a bridge making it possible to travel between two planets, I have some ideas but I would like to know if and how it would work. Maybe somehow stopping their orbit and locking...
I have a series of astronauts landing on an asteroid. I'd like to know the threshold of mass for them to not fly off into space. Specifications: Assumption is all astronauts are under 180cm, 80...
I had the idea to make an artificially constructed planet which is terrestrial, but has the diameter of Jupiter. Instead of being a solid sphere, it would be five spherical layers, with land on the...
A hypothetical species reproduces by females impregnating males a la seahorses. However, their reproductive system appears woefully ill-suited to this task. Their genitalia are outwardly similar to...
There have been many questions of moving, floral animals, most of these focus on their intelligence, but what about their sense of sight. I fail to understand how a botanic based alien would be abl...
When confronted with cloning which leaves the original alive, there is the known issue that the clone could want to replace the original (e.g. as seen in The 6th day). A shared consciousness is ver...
On Earth we don't really notice many effects of the Earth spinning, apart from the day-night cycle. It took a long time for people of Earth to realise that it even was spinning, but there are measu...
You gotta admit. That roguish guy you just met at space bar looks cooler with cig in his mouth. Not only he always shoots first, but also he manages to do so while puffing awesomely looking clouds ...
Before you comment "dragons can't happen", we've been there before. Based on the question linked above, assume dragons are scientifically plausible. You may change what you need about the...
In pillbugs, sex is determined by two chromosomes: Z and W. Individuals who inherit two Zs develop as males, while ZW individuals become female. But in some populations, these rules are over...
Could anyone could survive a nuclear war and all that follows? I have read many things saying they would, and read other science-based answers, but they all talked about a nuclear war that was re...
In my story, a portal is opened from the Earth to an alternate world. However, this world is toroidal in shape and has a surface gravity equal to that of Earth. It rotates around an axis that goes ...
I've read this question, but most of its answers don't seem to apply to my question directly other than possibly this one, which suggests that in order to change a planet's orbit, you would have to...
I asked a similar question a small while ago. Unfortunately, the way the problem was defined excluded certain viable solutions. So I want to try again. The society would have to be complex. Perhap...
Part of a series I'm starting since the recent What could make a star green? did quite well and others could use the information here in their worlds. There aren't any "violet" stars. When a ...
Here on the Space Station 'A long way from anywhere V' (not to be confused with any other space stations) a wide variety of species pass through on their way to the Krasnikov tube terminal. Even th...
How do you cut through an unbreakable armor? With an all-powerful sword, of course. No really, if we had seemingly unbreakable matter (lets give it the original name of Unobtadamentium, or Uium for...
The largest animals alive today--and to loom into the human imagination--are the whales, a group of mammals that had been going from skinny-dip to full-blown dive in just 53.5 million years. Due...
Human (spoken) languages have a great variety in terms of grammar and what the basic elements are, but they have essential features in common in terms of being a time sequence of phonetic primitive...
Or, technically, a civilization near the core of a planet. In this question I will describe some aspect of my design, and you may comment on the realism of these aspects and add improvements, or p...
I'm working on a quest (Space game, but don't ask, it won't be good in anything but story and even that may be a stretch. XD), and I'm looking to use our solar system, Jupiter and Saturn specifical...
