Let's say there is a planet orbiting a star. The planet is much like our own, with a similar atmosphere. However, the star this planet orbits differ from out star. It differs in such a way that it ...
I have come across a weapon by The Killing Star, which is called the Absorbic Bomb. Apparently, it reverses the formula E = mc^2, of how matter is converted to energy during standard nuclear blast...
The cylinder is 32 km long in total, 8 km in diameter, with 3km long endcaps, resulting in a habital area with a length of 26 km (= and an area of cirka 754 km2). The main body of the cylinder is...
Here on earth, it takes about 90,000 years for major ice sheets to build up, and another 10,000 for them to collapse, resulting in 100,000 year cycles of major glaciation, from what I understand. ...
When you have foresight, it's guaranteed that confusion will be your epitaph (thumbs up to the one person who gets the joke). Basically, it only grants you advantage on actions, so you still can't ...
Unless I am mistaken, a Jaculus, also called a javelin snake, is a creature found in Roman myth, described as a snake that hurls itself from trees and impales its prey. Its head is usually describe...
The metric system (SI units) is a base-10 measurement system based on the meter, kilogram and second. But it is tied to earth. A second, which historically was defined as 1/86,400 of a day, now d...
For an artificial gravity ring station, could you make a central hub, using similar magnet technology used to levitate magnet trains here on earth, to reduce the amount of mass rotating? My thought...
In our timeline Alexander Fleming accidentally discovered penicillin by accidentally leaving petri dishs out over a long period of time. If a person from an earlier time, e.g. ancient Rome, woke u...
Set in a parallel universe, in a galaxy far far away, an Earth-like planet orbiting a yellow dwarf star with the mass of 1 solar mass. And yes, indeed that planet comes with a natural satellite tha...
I was reading this question, and it made me wonder if something like this is possible or not. So, the question is, Is it possible to have an alien species in whom, the newborns are bigger than adu...
So, once there was a war between the titans and the gods. In the end, the gods' leader, Anon, found a way to permanently remove the titans from the world, but the victory extracted a terrible price...
as the title say my question is: What planet composition is need to have giant human that make earth human similar in comparison to ant size to them? i know realistically and probably its imposibl...
If a dichromatic mammal had better night vision than a human, including tapetum lucidum, could they see large (red) and medium (green) light wavelengths but not small (blue)? Would something simila...
What metal or material could be used to make super high-pressure canisters in the 1700s? It is for use as a fuel or propellant for a piston-driven engine to power vehicles, due to the fact that a g...
I'm trying to develop a realistic system with a limited understanding of astrodynamics. Is it possible to have two binary worlds capable of sustaining atmosphere and complex life orbiting one anot...
I was imagining a sort of post-apocalyptic/collapse setting, where a few centuries of climate catastrophes brought on by climate change cause essentially your general end of the world as we know it...
So, I was thinking about flavouring psychic damage and thought "If I'm anime > western civilization, then wouldn't it make sense for me to reflect it a bit more?" In an anime, I watched, there ...
From 2.4 to either 2.1 or two billion years ago, Earth underwent a surge in a waste product that we know as "oxygen". Before that, life thrived in an ocean rich with iron under an atmosphere loade...
If you were air dropped onto another planet, where multi-cellular non-plant life did not evolve, could you survive on what was only around you? The planet in question is a clone of earth, in almost...
During much of the Cretaceous period, oxygen levels were substantially higher than they are currently, with estimates indicating that around 30% of the atmosphere consisted of oxygen. Obviously, t...
Setup: Earth developed in an alternate universe with small oceans and little water. A little before animals first left the oceans and began to walk on land, when all of Earth's land was barren sand...
So I'm not really sure whether I get it right or not, but apparently most mammals are dichromatic. Humans have three cones that detect light wavelengths, small for blue, medium for green, and large...
Many mythological creatures have a popularity secondary only to the dragon (the one true global force.) Among them is the griffin, a half-bird-half-cat cut-and-paste. Now, in an alternate Earth, ...
In many fantasy settings, a race of mushroom creatures are often encountered. They may or may not look humanoid but still have the biology of fungi. My question is how. How can a mushroom be mo...
