Say that a heavy (150ish kg) android was involved in some kind of incident in orbit and came crashing back down to earth (traveling at orbital-ish speeds upon re-entry). Would they be going fast e...

I am writing a story where a freak magical accident causes a fully-formed landmass to pop into existence like it was there all along. For the purposes of this question, let's assume: the contine...
Each technology, that is evolving, begins with simple piece of programming code that starts with variables of certain data types. It is interesting to note that many calculative and computing techn...
I was thinking about how one of the reasons humans have been so successful is that we can adapt to live almost anywhere. A big part of this is that we can put on more clothes when it's cold, and ta...
How might a fictional parasitic superorganism like the Halo franchise's "Flood" function? Put plainly, how would the biology of a parasitic superorganism that grows by converting the biomass of o...
This question is focused on a purely chemical messaging system for humans that provides the same degree of nuance that spoken human languages convey now as well as all the information that smells c...
In a not-so-distant future, around 2300, mankind finally find a way to keep the body intact over hundred of years, allowing a limited number of humans to travel over hundreds of years in order to j...
A world, I am building, had been flooded, causing a species of fire ant that makes ant rafts to evolve a collective behavior, ditching anthills and becoming an ant-hill (I'm not sorry). Over thousa...

Entropy in a casual definition is the tendency of things to progress from order to disorder. There are a variety of specific definitions in different arenas of thought. For example, heat will diffu...
So, to make it normal for a human to have tetrachromacy, having four color receptors, would make our night vision nonexistent. In an answer in the question linked above, someone brought up the tap...
Inspired by this question, suppose that the Earth decided to move its orbit much further out to reduce the effects of, say, global warming or the effects of a dying sun (or far enough to make this ...
In a world where man entered North and South America without causing a mass extinction, all of the paleofauna which became extinct ~10,000 BC in the Americas are still around. There are several fam...
