I was looking for special missiles that do more than just explode or release radiation, thus I looked at some of the harder Warhammer 40k weapons, until I came across the Hellfire Missile. To desc...
I normally ask sci-fi questions, but oh well... It's fairly well established by this point that gills, while fine for fish, wouldn't work for mammals, as we need more oxygen than can reasonably be...
The Old Ones build continent-sized bunker complexes to protect themselves from the enemy, which followed through the cosmic ocean. The Hunter succeeded easily despite their efforts and their corpse...
Suppose an extra-solar object the size and mass of the Earth, travelling at a speed of $26\ \mathrm{km/s}$, the same of ʻOumuamua (the first known interstellar object crossing our solar system), h...
Let's say a few centuries in the future, we have captured an asteroid into orbit and built a space station out of its material. The station is a ring that encircles the equator in Low Earth Orbit, ...
I'm imagining a hypothetical scenario based on the Big Rip theory of the end of the universe (https://en.wikipedia.org/wiki/Big_Rip), where eventually the expansion of the universe causes everythin...
So as I was creating a variety of creatures I wondered if speed is exclusive to smaller creatures or if a large organism could move deceptively fast to take prey or predator by surprise. This is as...
Would it be possible to create a probe which could survive the crushing pressures and temperatures to reach the solid core of Jupiter and return data to Earth? What would make this impossible? This...
So, the dragons of my setting were inspired by several things, which include D&D dragons, a mockumentary and Asian water monitors. Now, dragons look something similar to this: They glide for...
Is it simply inevitable that on a planet organisms would split into motile and non-motile groups. I'm planning on creating slime-like amoebic chemotrophs for my light devoid-planet that are the "pl...
Imagine a gas giant as massive as Jupiter has a enormous planetary ring which will expand and contract throughout its orbit around a main sequence star. Then there is a moon as massive as Mars an...
So I'm working on this new novel with a fungal-like disease that is alien in nature and I have a question pertaining to spore germination. Some background - the disease is fungal-like, but not nec...
To help imagine it and my inspiration, it's basically similar to pictures from Abrahamic religions with burning trees like this one. They can't speak though, they are just trees or plants that are ...
This is a follow up question to: How realistic is the Swampus? What adaptations would current octopus have to evolve, to become land based, meaning that they spend at least 1/3 of their time on la...
In the 2002 documentary the future is wild, numerous biologists and other scientists speculated about the future evolution of various species. In the '100 million years in the future' segment, the...
I am developing a fictional planetary system in which a large gas giant planet (slightly less than the mass of Saturn), has migrated into the habitable zone during the formational years of the syst...
The Grey Alien trope almost always features a disproportionately large head, which often comes in unusual shapes to boot. There's nothing wrong with the trope, large brains are cool but what baffle...
"They fly now?" "They fly now!?" "They fly now" One of the most iconic characteristic of dragons is their ability to fly, on top of that, my intelligent (human level) dragons also use a fu...
The larger an animal, the harder it is to cool down. Ignoring the problem of bone/muscle strength vs size/weight and saying an animal could get to outlandish sizes, would a second cardiovascular sy...
The purpose of this question is to know whether or not organic tissue can be used to power and android. Compared to a nuclear cell or an ordinary battery this doesn't seem efficient, it needs food,...
Our estimates of our own habitable zone--a piece of space in which liquid water is possible--have varied over the years, but the current estimate is by Ramirez and Kaltenegger in 2017. Based on an ...
Bringing a human child to term generally takes place over a period of nine months. They are marked by different stages, from 1st to third, and are marked by different events and expectations for mo...
Assume planetary-scale cables are easily constructed, and subsequently ignored. I am assuming these cables would run just under the surface of the planet from one side to the other for minimal mai...
I was thinking of creating an alien planet that orbits a star slightly past the habitable zone, but is kept warm by an extremely dense atmosphere, made primarily of a black gas, but still contains ...
We already know how to heat things up, but what about cooling them? How do we make Earth's climate like that of Mars? Or go further: can we, by any hypothetical ways, make Earth somewhat like Pluto?
