The probe in my mind is unmanned, with a super-reflective surface to deflect most of the energy from the Sun on all wave length, only absorb enough to power its operation. Please also elaborate i...
I am currently reading an eternal golden braid, i've gotten as far as several lengthy chapters about the brain. He talks about neurons and symbols, what 'meaning' is and there is a lot of hypothe...
The light from the sun is dissipated in a sphere, so there is a squared relationship between the distance from the sun. Would it be possible to place either a lens or solar collectors with a laser...
I am trying to figure out how to make a moon (75% of Earth size) of a gas giant habitable. To give an idea of the technological level, here are technologies the colonists have access to: fully a...
I am trying to figure out how to build a human colony on a moon (75% of Earth size) of a gas giant. Some details of the planetary system chosen for colonisation: K-type main sequence star (about...
In my setting elves can see very well in the dark. I've suggested tapetum lucidim but that would make their vision less clear so would larger pupils make it easier to see in low light areas?
What is the best material to use for a near future spaceship. Assume that most materials in the solar system can be mined and used. The spaceship is 700m long, 500m wide and 500m high. It travels...
We all, perhaps, know the theory behind space elevators. Similar to the principal of a bucket on a string, suspend a large anchor in space that orbits the planet in synchronous orbit around the equ...
Given ample access to uranium and a race that is naturally resistant to radiation poisoning, how soon could a civilization invent nuclear reactors?
I'd like to have a large underground world. Imagine the "Underdark" which will be familiar with DnD folks. A huge network of large and small caverns connected by winding passageways. The occasio...
This is a self-contained follow-up to a different previous question. Based on the answers I got there I've taken a different approach to my original idea, and now want to try using antigravity on ...
Friends, Many years ago"”in a book about building space stations"”I read that humans can thrive and maintain enough bone density and muscle to successfully reacclimatize to live at 20% Earth's Grav...
While Prionosuchus and other large temnospondyls are definitely imposing and capable of causing mortal harm, they still adhere to a distinctly salamander-like profile. Anurans (relating to frogs...
I'm thinking of making a species that evolved in a planet that has a type of algae that secretes a nutrient rich sludge that the species only has to drink to survive. I know that this would make th...
Because I need a spine that works for massive and small creatures I'm thinking of making a plant-based spine (which has its own DNA). The spine acts kind of like a cucumber, in that when it sucks u...
Many animals have ears that revolve and pivot when they hear noise. Humans have vestigial structures in their ears that allow them to wiggle their ears somewhat. How would elves achieve this same e...
So my story takes place on a moon orbiting a gas giant about the size of Jupiter and I was wondering if it was at all possible for a planetary ring to exist beyond the planets Roche limit. I get th...
Scientists seem to be vacillating as to whether a Red Dwarf planet could support life or not. Imagine a G-Type star much like our Sun. Imagine an orbit that would make an Earth-Sized planet warmer ...
I am designing a rather sizable (~ 2000 kg) carnivorous predatory species and I want it to expel all the waste it produces in the form of dry, compacted pellets (similar to owl pellets, except of c...
I'd like earthquakes to cause deep gullies along some mountainsides of my planet. Here on earth, vertical fault scarps can form from earthquakes, but the examples I see online tend to be less gully...
The backstory of one of my characters involves being lowered onto steadily rising, open flames back first. The story is set in a dystopic/post apocalyptic time where modern technology became unavai...
In some parts of the world, termites are consumed opportunistically by humans. I'm considering the possibility of using mound-building fungus-farming macrotermes as livestock for a culture of corvi...
Humans developed martial arts to give themselves an advantage in combat against untrained, but possibly stronger or better-armed opponents. Presumably, martial arts are one way of making up for the...
Meet Joe. Joe is generally an average person with one special trait: He loves astronomy and star gazing. However, Joe has a great paying job as a web developer. He earns 120 000 USD yearly and has...
