Assume that you have a Rogue Planet hurtling through deep space. Somehow, an alien civilization from, say, 1,000 ly away acquires astronomical data from this planet. This data is in the form of h...
Imagine you have a weather-controlling device that you use to eliminate all lightning strikes. They're just too dangerous. What happens to the earth? Does lightning serve a necessary purpose to ...
I'm in the process of naming some routes and roads in my medieval fantasy themed world, and I want to specify routes that could only be managed on foot. I'm tempted to say trails, but since every b...
On my Conworld, the oceans are purple. This is mostly for aesthetic purposes and my current explanation is an abundance of cyanobacteria. I'm not sure that this explains it correctly, so what could...
In my world, a "perfect" robotic eyeball has been created. This eyeball is electronic, but it emulates a human eye perfectly. This does not necessarily mean that it has millions of synthetic cones...
My world is set in ancient times on a planet similar to Earth, but with a different civilization and different geography (and lots of canals). I need to find a way of giving the inhabitants better ...
I want to propose a new method for tree growth to exceed the max of 120 or 130 meters restricted by Earth's gravity. I propose for the tree to rely very little on its base or roots. The living part...
I'm working on a sci fi story where one of the species has batlike wings and comes from a moon around the size of Titan with roughly the same atmospheric pressure as Earth. Initially, I thought the...
Hopefully this isn't two separate questions - I do feel like they are interconnected enough that they can be counted as one. I'm wondering if it would be possible for primitive human ancestors. Le...
Spacecraft in my Scifi setting use strong magnetic fields for many purposes. Fusion containment, magnetic nozzles, gauss guns, magnetic fields as pusher-plates for nuclear pulsed propulsion and def...
My jet-propelled squid uses a scavenged shell for its pulse jet deflagration chamber, I am trying to determine how often he'll have to replace it. Including the shell it's a 5 kg animal using a ...
A familiar scenario in scifi: a bubble of space is isolated artificially from the outside world by means of time dilation: time inside the bubble moves more slowly than time outside it. Assume that...
I've been thinking of the idea of creating and adding an alien species that's antimatter-based (being from a universe where antimatter became the majority instead of "normal matter"). However, I'm...
So I have this underwater echolocation using species. I'm wondering if they could have a language partly based on recreating sounds from returning echolocation waves to 'talk' images at each other....
How would human appearance be different from what it is now if our circulatory system used Hemocyanin for oxygen transport instead of Hemoglobin? Limitations, restrictions, additional details, etc...
Things like Dyson spheres need a whole lot of raw material, which is rather difficult to come by, since the elements needed for good structural steel are scattered fairly thinly into the universe u...
If I want a home for aliens like those which invaded in Battle:Los Angeles, what would be the best fitting features? The aliens: Burn water for fuel (assume they are using deuterium for fusion) ...
I'm working on a roleplaying game in a medieval fantasy setting with a focus on crafting and I am having trouble visualizing how armor made from scales of creatures would be assembled; both for art...
A group of scientists discover a heretofore unknown species of fungus. unbeknownst to them, let's say it is of extraterrestrial origin but it operates very much like certain fungi on Earth (e.g. op...
I'm interested that some ULF (ultra-low frequencies, especially the 17 HZ zone) can cause humans to experience sensations of fear, trembling, or even claims of seeing ghostly apparitions. What an i...
What would happens if due to increased volume and reduced density, the global warming cause consistent loss into space of certain gases of atmosphere? What would we observe?
Are there any holes in the following reasoning? Black holes form gravitational lenses. So they bend light. Is it possible for an observer to see his own past image as a result of light bending aro...
Alright so in my sci-fi a prominent corporation dominated by the Borlak species (Mantis-like Hexapods). The Borlak make their money by mining "dead systems", solar systems without any habitable pla...
I'd encourage you to take about 4 min to read the whole post. Multiple masses of parabanic acid appear at random around the world (but see Context and constraints), displacing any matter in their ...
In my fantasy world, there are several species - both sapient and non-sapient. They all originally evolved from a group of insects that, after millions of years of isolation and no competition, hav...
