Space nets are a theoretical space organism designed by Tim B, to quote him: Imagine a life-form shaped like a giant net. It gathers space dust into itself to grow, using light from stars bot...
What would be the best way to launch space craft/get into space from a northern latitude? Canada, Scandinavia, UK, Russia, Alaska, those sorts of places. I understand that being closer to the equat...
Would it be possible for a virus to extend the average human life-span (but only by about 50-70 years max) if the infected people kept it controlled enough where it wouldn't (alternatively) kill th...
There is a nocturnal mammal, about the size of a common red fox, which has evolved (by way of some unspecified-at-this-point selective pressure) the ability to see well in situations involving larg...
Let's say I have a Dyson sphere roughly the same size of the earth with a very small "star" in the center. Continents, oceans, and people inside the sphere experience a reverse gravity in the oppos...
Could a kugelblitz be stored in a container lined with metamaterials to reflect back the outpouring of hawking radiation or would it require something more exotic? Could it be pinned in the center ...
Knowing that our brain uses just about a few watts of power and is as powerful as a supercomputer using megaWatts of power in 2016 and that we seem close to the physical limit of what silicon can d...
Spaceships are a peculiar thing. We've got them in all forms, sizes & colours. They are everywhere and go everywhere else. carrying with them anything from music, over tractors, to foodstuffs a...
If you arrive at a distant planet you mean to colonise, without enough food for the long term - just maybe a couple of plants and a bunch of seeds and enough food in storage to keep you going for t...
The Hoatzin is a jungle bird whose only remarkable trait, other than looking fabulous, is that their wings have fingers. Is it possible that these wing fingers could evolve into arms? What abou...
This scenario requires an alien creature with a decent chance of defeating a modern armor in a brief combat. This alien should be: At least as large as a horse, but not much larger than a semi-tr...
So take a creature like a werewolf or a Fallout deathclaw. Either through evolution or genetic engineering has claws with a graphene edge instead of keratin. The claws work like a more organic v...
Even now, in 2016, if you take a look around in a 7-Eleven or any European counterpart of similar small shops, you can find a comparably huge selection. In fact, this applies to large counterparts ...
I want to set up a long-term self-sustaining colony on Mercury. What and how needs to be done for a colony to survive and thrive on the planet Mercury?
Scenario: A generation ship travels to a star system that has at least one planet that's believed to be potentially habitable and, therefore, a possible location for a colony. After sending some p...
I have an asteroid. I want it to hit Earth. The best way to hit Earth is from behind the Sun, which makes it harder to detect you if you're an asteroid. Now, I have a basic understanding of things ...
What would happen if all dark energy (cosmological constant) instantly converted to radiation due to vacuum metastability event, while otherwise vacuum properties remain the same? Dark energy dens...
If two planetary bodies were tidally locked to each other (e.g. pluto and charon) then could there ever be a situation where the smaller of the two bodies had the 'heavier' gravity? Could you ever ...
My world is based on the concept of afterlife, with a twist: people who died in other worlds are resurrecting in mine. Once in the afterlife world if they suffer another lethal injury or condition ...
So I'm pretty sure your are all aware of what a cell is the microscopic organic units that make up all life. Well they don't have to be microscopic. An unfertilized chicken egg is a single cell. ...
A short time ago I read that life might be possible on interstellar planets (i.e. planet-like objects which aren't bound to a star by gravity.) They may be insanely cold on the surface but inside t...
In a world I am building, I want the primary species to be 100% peaceful. The best way I have thought of for doing this post-sapience is to remove all identifying traits (skin, eye and hair color, ...
Cube worlds are cool and many people like them but unfortunately, they are less than feasible. Does this have to be this way though? What factors could lead to the creation of a roughly cube shape...
Far in the future, I have a bomb about to detonate in the skies above my city, a real city/province killer. A hero dramatically manages to enclose the bomb at the moment of detonation in a living c...
Stanley Miller's experiment was an amazing step forward in unifying inorganic and organic chemistry. It was also a landmark development for the theory of chemical evolution. Miller-Urey Experiment...
