You don't understand the concept of the Dyson Sphere if you are trying to "get rid" of all that heat. Heat is energy, and the DS is meant to capture the energy. The "sphere" requires many new techn...
I understand that the answer is already accepted but: albucierre drive lanes. Albucierre drives create a kind of fold in space you can ride and achieve FTL without really going FTL. A disadvantage...
Art-critic types would fulfill meat gathering roles and such. Imagine that someone prefers to write books for a living, they'd go get a job digging holes if they couldn't afford to eat or clothe t...
The search engines see imported posts as duplicate content, and penalize us accordingly. Scientific-speculation.codidact.com is essentially black-listed, and some of that even seems to be spilling...
Can electricity be generated directly from nuclear decay? It occurred to me that in alpha decay two protons fly off rapidly, leaving their associated electrons behind. If the alpha particle was ca...
Is it plausible to assume that the total amount of water (edit: water molecules) on planet earth was, in different periods of earth's history, significantly lower or significantly higher, or rather...
I've looked into the usual structure of typical animal rhinarium (hairless nose skin with nodules), and it looks possible? — Rhinarium skin structure and epidermal innervation in selected mammal...
There seem to be two separate questions here: Would a moon colony need to be deep underground to get more gravity? No. This is basic physics. Going deeper into the a gravitational body reduces ...
Define every single human by their own phenotype, generation and breed. DNA analysis has a price but it's not too expensive, childbirth has never been cheap afterall. This way your identity is ba...
This question is a little nebulous unfortunately and perhaps a bit disturbing. The evil-empire in my WIP captures Mages and breaks them down into loyal and obedient servants. The Mages aren't as d...
This can't be answered because it depends greatly on the details of some drug/process/whatever that caused them to stop growing You made this up. Only you can say what the long term effects are....
In the foreseeable future, a scientific community has discovered an alternate universe in which the solar system centers around a binary system of G-type suns, unlike the one G-type that ours orbit...
That question was off topic for two reasons: There was no speculation. Paraphrasing loosely, this site is about "what if" questions with a foundation in science. It was about history. This is n...
As mentioned in this discussion: How to keep humans pilots instead of AI in sci-fi future? the ability to handle G forces is a limiting factor on what pilots can do. Some of my solutions to addres...
A simple enough question, but one that Grimmsdottir and I agonized over. Basically, what would enable close-ranged fighting between space fleets/ships? We both agreed that having gargantuan ships ...
It's becoming obvious from how could humans recognize another species as sentient / intelligent that recognizing another species' intelligence is very complicated. There are no universal tests, no ...
The story begins in classic disaster film style. A small rogue black hole is approaching our Solar System. It isn't going to get close enough to destroy everything, but it will agitate our Sun, ca...
The Technology We're in the year 2250 on an Earth-like planet. All the space on the earth's surface has been used up by the population of 15 billion, so we're moving into the air. Cities, along wi...
Given Earth's current level of technology, space- and ground- based astronomical tools, etc., to what extent would it be possible to locate the Milky Way from a somewhat distant galaxy, say, in ano...
I am working on a 2D platformer game, and I'm trying to introduce a jetpack which would give a shinespark-like ability from Metroid series, i.e. it needs a run-up to a certain speed, at which the e...
Is there a way to create a nuclear explosion that only destroys things within a few feet of the bomb? The point is to completely eradicate something relatively small, leaving no trace. Let's assum...
Suppose we have a rocky planet (somewhere between Earth- and Super-Earth- sized) orbiting a star far enough away that it would be around Pluto's temperature if sunlight was the only heat source. If...
Suppose our alien neighbors woke up on the wrong side of the bed and decided humans would be less annoying if their home planet was hit with a giant artillery shell travelling at half the speed of ...
I was wondering if a small black hole would make a feasible/possible propulsion source, and if so, how. Pros Black holes release Hawking radiation, would should be easy to direct in a certain ...
Is it possible to contain similarly charged particles in a magnetic field or traps, in generally large scale (say, all of them have positive charge), and could be utilized as power reserves quite e...
