I want the Netherlands to be flooded entirely, and I want the event to be of such a scale that it goes faster than hydroengineering can keep up with. This will mean that I need a sea level rise of ...
In my story there will be animals that are incredibly strong and resistant to injury. To better understand how to design my creatures, I'm asking for help understanding how to make the Eurasian Br...
We all know that the universe is going to die one day: all the stars will die, all the black holes will evaporate and life will be gone. But hypothetically speaking, if a super advanced alien race ...
The situation I'm considering is as follows: A large research vessel with a crew of about 100-200 attempts to land on a potentially habitable planet, but something goes wrong during the descent. A...
I've been grappling with a story for a while, involving a scenario where gravity starts to fail. The goal of the story is mostly how people react to the knowledge that the world will end. But, I al...
This is something that is starting to bug me, I'm creating a universe in which space travel is cheap and comfortable and space habitats can be built roomy enough that no-one actually needs to live ...
I've had this idea for a short novel, at the intersection of the One thousand and one nights and the Multivac (& co) short stories from Asimov. The idea is that there's some kind of super AI t...
Humans are savage creatures. This is indicative in the way they get rid of bodily waste. Squatting over a glorified hole in the ground or aiming their spear tip toward same hole and hoping for succ...
Slimes are seen as merely base-level enemies which don't really challenge the heroic main character, the Chosen One. My question is how to make slimes incredibly powerful without using magic. The...
In my yet to be named sci-fi universe humanity has begun to expand into space and has established large scale space stations near Earth and on places like Eros and Luna. I wanted the stereotypical ...
Is it possible for a planet in our part of the galaxy to have a night without stars? I'm looking for some kind of natural phenomena that would hide the stars, but allow the sun to rise and fall as...
I'm writing a story in which a civilization previously capable of (firmly technobabble-based) FTL travel has become stranded, orbiting an isolated star with no rocky planets. (There was a planet, b...
In my story, something pretty insane happens during the 3rd season. The common conception was that an asteroid strike contributed to the extinction to dinosaurs, but unbeknownst to all it was not...
For an elf-like race whose people do not age beyond physical maturity (the accumulated DNA damage associated with aging does not occur), what would prevent overpopulation? This elf-like race is f...
I'm my sci-fi setting's history, various hominid species are in competition with each other for dominance of earth and its resources. Among these races are "Halflings" ... okay, not haflings per se...
Researchers are developing increasingly powerful Artificial Intelligence machines capable of taking over the world. As a precautionary measure, scientists install a self awareness kill switch. In t...
Imagine a single, long, straight stretch of track. On the track there is a train heading in one direction at 100 km/h and a second train heading towards it at 200 km/h. The latter train is a specia...
