This is a question for an alien species. Is there anyway to scientifically justify having two separate beings/creatures that depend on each other for life? In other words, two separate bodies tha...
For this question, the word 'metals' does not refer to elements heavier than hydrogen and helium. It instead refers to metals as defined by the periodic table of elements. After researching the ab...
66 million years ago, the dinosaur empire was in its death throes when its final nail in the coffin came hurtling down from the sky. A clump of rock the size of Mount Everest smashed into the Gulf ...
I'm building a world with humans being genetically engineered species, created by certain advanced Alien civilization ("gods", Creators etc ...) like in the Sumerian hypothesis, but with a twist: t...
The square-cube law applies to bodies with the same shape, and require them to be increased/decreased in all three dimensions. If you were to take a cube, with every edge being a long, and expand i...
Having read previous questions on radio wave communication on biological creatures would it make sense for race of alien creatures to have developed dish like bone structures for radio wave communi...
In my story, there is a planet that experiences near constant sunlight. Since sunlight so plentiful and reliable most organisms are, at least in part, photosynthetic. The only intelligent life on ...
I understand, vaguely, how human voices vary with the overall size/shape of the individual(s vocal chords), and I can use that to make reasonable assumptions about what the voice of non-human fanta...
Warning lots of text ahead. The fluff: The story uses a Catastrophe Inhibitor (CatIn) to stop nukes, orbital bombardment and other such weapons from being the go-to method of defeating everything...
Currently, NASA is investigating the use of hydroponics, aeroponics, and other low soil techniques to grow regular plants for consumption and oxygen generation/CO2 removal on long voyages in space....
A radical shift in the Earth's orbit has made the Earth much colder, with all the oceans freezing over, and the atmosphere liquifying and falling as rain. Humans live deep underground in areas of h...
Pretty simple (in theory that is) question for one of my worlds. I heard carbon fluorides are intense greenhouse gases but otherwise harmless and didn't lead to large issues (atleast none that I co...
After receiving answers to this question, I now know that viruses cannot be written in machine code in such a way that they can universally infect all kinds of systems. Every machine has a unique s...
There's iridium-based blood called Chloro-carbonyl-bis(triphenylphosphine)-iridium that's effective at transporting hydrogen alongside oxygen. What I want to know is that, are there other metal-ba...
This is a follow up question to one that I made earlier. Basically, after God wiped out all life after the flood, earth has changed into a lush but dangerous environment. Every living thing, from ...
Say there is a plant-based toxin that causes what is essentially a state of deep sedation but has no other real effects. In this world there is one animal that is immune to this toxin (the plant is...
God had decided that humanity as a species is an overall disappointment. After wiping out all life with a flood, he decided to start from scratch. Humanity's new environment would be constantly cha...
I'm writing a sci-fi story with some fantasy elements, and I'm trying to keep even the most outrageous moments grounded in the laws of our universe. This is one of those moments. The Situation ...
Suppose a two-storey timber cottage has been left unoccupied for 15 to 20 years. The entire structure is wooden, including all beams and supports, with a rammed earth foundation. It's situated with...
Aye so, so I been thinking about the square cube law and such and I was wondering if say, for a humanoid or a human or some creature, to be larger than average but keep similar proportions to the o...
In my world, there was a man that wrote a virus in binary code - which in turn infects every computer-based system in the world, as long as it is connected to the internet. Is this even possible? ...
It is inspired by this furry trout. I mean fish (not necessary to be a trout), not aquatic mammals, and real fur, not from fungi or mold (or looks like fur because of the dead cell, like Mirapinna...
So, I have been watching a lot of flat-earth debunking videos on YouTube, which has tickled my world-building bone. So, I'm imagining a world with a sphere of sunlight-level luminosity hanging rela...
Why and how could an organism evolve to make its bones or exoskeleton out of a UTH (Ultra High Temperature) ceramic like TiB2, WC, B4C, or TaHfC? Is it even possible?
One popular theory to explain how Earth got its water is that it was delivered by asteroid/comet/etc. The form this theory usually takes is that many small impacts occured over a long time, each d...
