Pssst! Come here! Imagine an ecosystem where animals have evolved highly developed mimicry of each other's calls (perhaps they have the universal vocal apparatus discussed in earlier question...
This is the ideal set up for my solar system: EDIT It's been pointed out that this is not a stable set up, so I want to clarify that everything in this set up can be changed at will to fit my plan...
It would preferably be something that will either last a fairly long time fifteen to twenty years perhaps, periodically and last at least some months between or last indefinitely. I do not require ...
In this universe, mass and gravity work differently so stable torus planets are possible (donut shaped). How would a torus world orbiting a single star have to rotate in order to have a stable da...
I am looking at realistic options that could damage the Earth so severely that it would be impossible for mankind to survive there and that would also not allow us to just colonize other planets or...
What can a country do to become self sufficient in isolation and can it improve its technology as fast as countries such as the USA, Japan, or Russia?
Compressed archives in computer science are, from some perspective, decreasing the data size by minimizing repetition of data. Take each particle (to any precision you prefer) in the whole univers...
The character I'm working om has the ability to compress/decompress air in a 2 foot radius around his body. His signature move is the "Thunder Punch" in which he compresses the air in front of his ...
I'm a supervillain. I have no name, but you can rest assured my intentions are dubious and always result in general harm. My biggest problem these days are these pesky superheroes keep finding my ...
I just detected a strange object in space, and it appears to be of alien origin! Telescope readings seem to indicate it is some sort of deep space probe, with a golden disk of some sort attached to...
This is a followup to this question about city building on flood plains. There is a civilization that developed along the rich varzea flooded forests of an enormous rainforest river, larger than ...
How can a part of a continent (super or other) remain unexplored by the apparently civilized majority? The undiscovered part must be habitable but inaccessible, by land or sea, so that the rest of ...
My colonists have been terraforming a planet for centuries. They chose this exo-planet for its many earth-like qualities (size, gravity, Goldilocks zone, volcanos, similar sun). However, it is like...
So one of the aspects of my science fiction world is genetic manipulation and modification of humans by one of the factions. I am wanting to have a subset of humans who receive a single eye transpl...
Ships are capable of FTL warp and relativistic speed flying. In order for a ship to intercept other ship at high non-FTL speed, it needs a mechanism that will enable it to slow down the other ship....
While asking another question about Jormungandr, the Snakebot of Doom, a point was made that it is so big and hot that it might produce its own weather effects. To that end: Jormungandr is 446 me...
I watched Independence Day: Resurgence the other day. In it, Earth's first line of defense is a lunar base (that gets blown up), followed by an orbital satellite network (that gets blown up). Now...
My generation ship aliens have 2 thumbed hands. No, not the 2 thumbs on the same side that some humans have but the 2 thumbs on opposite sides. So it would be kind of like this: Except more rept...
So I am building giant spider species in my world, but I want to make semi-realistic changes to their physiology in order for them to be possible. Pack hunters like these spiders which hunt coope...
I'm writing a species of dragon-sized butterflies¹ as flying mounts into a low-magic fantasy setting², and would like to know if these creatures have to be imbued with magic, or if they could jus...
Vantablack is very dark, absorbing 99.965% of light. I've also heard it absorbs waves beyond the visible spectrum. Does this mean planes painted with Vantablack would be invisible to radar? If ye...
I'm imagining an intelligent race of beings with only one major difference from humanity: that they share one mind. Biologically speaking, they're identical to humanity, and their world is, by all...
I want to create a character with the ability to simulate an increase or decrease of gravities effect on an object or area. Is this possible? Restrictions: Gravity will still work (I want to work a...
I was wondering about a setting where a moon orbiting a gas giant can sustain human life on its surface, i.e. with nearly identical conditions compared to Earth (e.g. size, gravity, mean temperatur...
I have a bomberplane capable of carying a nuke. A large nuke. Let us say that I don't like the idea of wiping a city from the face of the earth. Instead, I decide to mass-produce solid CO2, and dro...
