Okay, I have a bipedal creature around 500 to 600 pounds (226 - 272 kg), and I wanted it to lift around 2 tons (1814 kg), preferably over its head, and throw the weight about 10 feet (3 meters) on ...
Ignoring the plausibility of their evolution and sources of food, could a whale-like creature which internally consists largely of hydrogen bladders/gasbags realistically stay aloft? If these cr...
Snares are anchored cable nooses set to catch wild animals. There are two types, active and passive. An active snare has the wire under tension and a trigger to cause it to snap closed, while a pas...
From pictures I've seen, all rocky planets in our solar system are some shade of grey, brown, and red. Ignoring stuff like atmosphere and oceans and plant life of course. I was thinking of a world...
This is a partial extension to this question: What kind of natural armor would stop bullets? I was wondering if a creature could grow armor in such a way which would allow for it to detach a porti...
I am building a world where most of the wildlife is capable of flight and there is an ecosystem that is almost totally isolated from the ground. Is it possible to have a mammal, roughly the size of...
On a planet, a species uses magnets (i.e. float in the air) instead of wheels for transportation. Roads are easy enough, just slap some magnets in it, at it works. But I was wondering about the f...
I'm designing an ocean planet. I did a quick search with this question on the interwebs, but nothing that came up was helpful (I don't have any physics or scientific background). I was wondering wh...
A civilization is very good at bio-engineering, and I was wondering if there was any kind of chemical an organism could produce which would produce viable rocket fuel. It has to do a of couple of ...
A weapon is needed for a climactic battle against an otherwise invincible wolf monster. In principle it could be any random thing, like the traditional silver, but we want something based in scienc...
Following on from my previous question here concerning the ancient civilization I have called the Androy and their struggle to survive terrible drought conditions on their planet. After years of s...
/Edit : so, I would like to create character which is supposed to have some metal grafted under his skin, but by under his skin I mean straight under, like a second layer. This is supposed to be li...
Using only existing technologies, can we shoot 4-5 kg bullets into a stable, specific Low Earth Orbit (at least 1000 km)? The bullets don't contain "hardware" such as electronics, so acceleration ...
This is my first post here, but here we go: I have been creating an alien world for a while, and the sentient species on it is very canine-like. They have a canine body, legs, and head, and the on...
In my universe, there are two ocean-based planets floating in space. I would like to merge them together in a realistic way. What kind of event could cause the planets to merge into a bigger one? (...
There are seven planets, and each one has a different coloured sky. One has red, one has orange, all the way up to indigo and violet. Of course, they don't have a sky this colour all the time, but ...
So, the end-point I want to work towards is a creature that lives on a high-gravity planet that has some sort of adaptation that neutralises the effects of that high gravity, ideally in a way that ...
In a world where torch ships sometimes will accelerate over 10Gs for hours, maybe sometimes days on end. Is there any way to keep the crew alive and preferably fully functional in during such hars...
I'm designing a world in which starships have renewable energy, refueled by parking around black holes or stars and recharging batteries with solar panels, but what fuel for an engine could be extr...
Imagine the following star system: The star is very much like ours. Orbiting this star is one planet, very much like Earth. Let's call it the Orb. Orbiting the Orb are two moons: a large one, Mon...
In my story, technologically advanced aliens create a "white hole" at the center of the sun that constantly spits out matter (hydrogen) from a parallel universe, increasing the star's mass quickly....
Let us take an earthlike planet. Approximately same radius, atmosphere and climate. Now let us create an approximately circular, paleovolcanic mountain approximately 30 kilometers in height and 15...
Similar to other suggested dynamic structures using kinetic energy to provide structural support, I am considering options for resisting external pressure in a vessel (e.g. a diving bell) by incorp...
Taking something like the anime Log Horizon as an example, where NPCs (non-player characters) are essentially humans, but in a game (let's wave our hands and say that the tech is available for maki...
Enter Iaeptus - A million man mission born on a fleet of ten thousand ship to the outer solar system. Their commander : Minevera, a brain-in-a-vat super computer. With a weight of 5 tons, a neuron ...
