Let's assume that sometime in the far future, ice-mining on Europa has become a very profitable business venture due to dwindling fresh water on Earth and the growing demand for more water from the...
It's the height of humanity's space-colonization golden age when casual interplanetary travel has become possible and humans have either colonized or established large space stations around nearly ...
Would there be any benefit to this? At first I was thinking if you had an outpost on Mars you could spend less money on the actual trip to the belt itself, but I'm not sure if having your launch st...
Aside from resorting to a grey goo-ish nanoplague that kills indiscriminately regardless of biochemistry, how might an alien virus, bacteria or other pathogen still be dangerous to humans? Could a ...
As we all know, hydrogen and by extension water, gaseous, liquid or frozen, is pretty much everywhere in our solar system besides maybe Mercury. The most abundant source may be the Asteroid Belt, w...
Think basically a Jupiter brain (a megascale computer made from a gas giant) but with a Dyson shell surrounding it to act as a threefold nutrient/waste exchange (assuming it repairs itself and adds...
As in, could negative matter (N.B. not the same thing as antimatter) exist on the macro-scale as a solid, liquid or gas without the weird effects that cause it to repel normal matter and possibly v...
Self-explanatory. I have a planet-eating entity moving slowly across the solar system towards Earth and I wanna know how long it would take for us to notice its presence once it starts consuming Pl...
Assuming the wars of the far, far future aren't either fought exclusively by unmanned spacecraft/robots/drones or in ways so incomprehensible to us that comparisons are meaningless, the only foolpr...
Okay, so I have a species of tree that's absolutely enormous, 1-5km tall when fully matured. Its immense size is supported by a large base, bark that incorporates a 2-d carbon lattice for strength ...
To elaborate on the title, can alien plant life on an Earth-like planet look similar to ours, or would plants on an alien planet be radically different, unrecognizable, or incomparable to Earth pla...
My story has brain uploading, but in practice it serves a purpose more like reincarnation, recreating the original recorded state of the scanned brain in a pre-prepared clone of the deceased. I nee...
And I mean faaaaar future. Like, twenty thousand years minimum. 13 million years at maximum. Let's say the Earth is doomed and to avoid the impending extinction of the human race, we throw most o...
Okay, as an extension of my previous question, I'm just going to lay bare all the details I've written down about this planet (including corrections from my last question), and ask the big question...
Like on a scale of one to ten, how plausible are Alcubierre drives in terms of our current understanding of physics? Plausible enough to be considered "hard sci-fi", or are they just another form o...
After reevaluating my sense of perspective on sublight interstellar travel, I'm thinking of moving my planet closer to Earth to cut down on travel time and fuel costs. However, the planet my coloni...
And I'm not talking about insects. In what kind of environment could a large number of different species all develop six legs/limbs/appendages the same way most vertebrate species on Earth have fou...
How scientifically plausible is this? A giant, self-aware fungal supercomputer made or evolved from something like the Blue Mountain honey fungus or maybe a slime mold of a similar size? Could some...
So I've got a bunch of freeze-dried colonists traveling in torpor to a solar system 55 light years away at 92% c. From an outsider's perspective it takes them sixty years to get there, but how long...
A caveat I will begin this question with is this: this system MUST be entirely organic. In fact it must be EVOLVED. Therefore Ghost in the Shell or Metal Gear-style nanocomms or cranial implants ar...
So I had an idea earlier today and was wondering. Most sources you consult about the supposed "vacuum metastability event" say that the bubble would begin expanding at NEARLY the speed of light, no...
Another question about my exotic matter planet. I mentioned floating landmasses via anti-gravity and exotic matter mining, but I recently read this: https://www.sciencenews.org/blog/context/fact-a...
Okay so we all know that one planet from the movie "Interstellar" that orbited the black hole Gargantua. How do I NOT get that? What's the minimum safe distance for a planet to be from a black hole...
So here's my rough idea for how you could basically send one large ship with a crew of a few thousand (at least ten thousand, maybe forty) to establish a colony on an Earth-like world: First step ...
So I want my planet to have six suns, but I'm not sure how far apart these stars would have to be from each other to not produce adverse effects on the planet that would prevent life from developin...
