This is another question for a setting I mentioned in previous questions (currency, ammo). The setting is: It's happening in post-apocalyptic SE Europe (Balkans specifically), about 60-80 years fr...
I am writing a Sci-Fi story that involves space ships shooting each other, as is the custom. I'm using a lot of handwavium, e.g. reactionless drives, FTL, gravity plating, etc., but I'd like the ac...
I'd like to keep this as science based as possible. I'm not even sure if this sort of question fits this exchange. Is there a possible world wide affect that when triggered (by human/cosmological i...
I'm trying to build a world that is orbiting a red giant but sustains life similarly to the conditions of earth.Since red giants are about half the temperature (3000 kelvin) of our sun (6000 kelvin...
Is it possible for humans to survive on the surface of the Earth, assuming the Sun was, for some reason, not emitting any light/heat/other radiation? Would whether the Sun was actually present affe...
Language revolving around the Sun would probably not be used on a planet with a different star, right? For example, if a planet was orbiting Sirius, "siriuslight" or "siriusburn" seems a tad clunky...
I'll confess that I have a real issue with iron--it rusts quickly. In fact, the History Channel program Life After People constantly states that, left to its own devices, the iron that makes up a ...
So in most fantasies elves and men are very similar in their physical appearance to where they look mostly the same, the only way they tend to be physically differentiated is by their ears and clea...
In my universe, there exist molecular level machines that can behave as a single entity. The humans use them for many purposes, including faster than light travel. The concept is as it follows: T...
This question (and the links I found for my answer) Can a "dune" worm actually swim in sand? got me thinking about how a sandworm might reduce friction while "swimming." One idea I hit on would b...
I am still working on my intelligent detrivore alien species and so far I have gotten some great help from you guys. But after searching online a lot about detrivore psychology I still cannot find ...
There's this creature that swims over the surface of water and it's giant, almost the size of a whale and has thick scales as armor over its back. This creature almost never dives underwater so fro...
How much caffeine could you fit into a roasted coffee bean (that will later be ground and steeped) while still having a strong coffee flavor? I'm aiming for a super-caffeine boost -- something whe...
I have a bipedal kaiju-style monster that walks upright on two legs and weighs 20,000 metric tons. Supposing, of course, that it can carry its own weight, its muscles can support the stress, and th...
One of the ways to create a major mountain range is a process called subduction. Here, heavy oceanic rock sinks beneath the lighter continental rock. The result--coastal mountain ranges like th...
The development of microgravity cuisine is an interesting topic, especially when it comes to transferring simple processes like the successful thermochemical processing of muscle tissues (e.g. barb...
From what I can tell, pulsars emit light in beams from the poles of the pulsar. Would it be possible to construct something to get energy from a pulsar's beams of radiation? Or is this as idiotic o...
What shape would the eggs of a species of oviparous humanoids be? Eggs are common enough that you'd be hard-pressed to find someone who hasn't seen one. While birds' eggs are often thought of more...
Ok, I get it, me dumb, you smart. Only smart questions allowed. In any case I'm going to leave the question unaltered in case some others might get something out of the answers. Thanks to everyon...
I would like to better understand intragalactic ship design (aka, "spaceships"). It's travelling at a barely tolerable 0.05c (86 years to Alpha Centauri). It happens to impact with a baseball (14...
I've heard several schools of thought. From a hard science standpoint, could there be gravity on the habitable surface of a Dyson Swarm plate? I keep thinking no. But if the outer shell were to b...
Would two moons of equal size and distance on opposite sides of a planet counteract each other's tidal pull?
I've seen many sci-fi scenes that feature a ship underway on a deep space journey. As the ship passes the vantage point we can see engines burning during sub-FTL speeds (The Expanse most recently)....
So when I say everything, I mean everything. Humans, animals, plants, fungi, bacteria, all dead. If the bacteria and other detritovores and decomposers can't decompose anything since they themselve...
Is it possible with some chemicals as intake for humans to completely convert the food/chemical to energy to survive? This is similar to when we are talking about clean energy where water and some...
