If a three-month dark period was a normal, recurring, part of a 15-month calendar, and plants had evolved to be bio-luminescent, could they survive? Would only some survive and, if so, would it be ...
I'm thinking of having a world that has a moon that's been partially split (so not fully halved) with the debris slowly separating from it. At night you'd see the split moon mainly and lots of var...
OK, OK, I know, darkness is nothing but absence of light, so there can be no substantial darkness. Darkness, on its own, doesn't exist. But, can we not get pretty close to this? Can there be some...
This is an edited hopefully more focused version of a question I asked a while ago. I made the mistake of asking too many questions the first time so I'll try and be a bit more focused here. I d...

Let's say I have a terrestrial planet superficially like earth, except that it rotates much slower (about 10-15 days per rotation) and its atmosphere is ideally several times thicker. If I want thi...
I don't wanna reveal too much about my world, however, the basic idea is that there is a town of people who live deep underwater (they are biologically capable of doing underwater gas exchange and ...
I was wondering whether it would be feasible to have a tree that at times may have light green, at other times dark green leaves. Why would a tree evolve to change the shade of its leaves? Yes, I...
This question has its origins in the word "dendraphile" used in a YouTube comment. It was used in an insult used by dwarves towards elves. My chain of thought then was that the dwarves would use pl...
You're a lone immortal who's decided to breed raccoons to a human-level intelligence (over the course of hundreds of thousands or millions of years). To do so, you need to both feed a significant p...

Given a rotation rate comparable to Venus & axial tilt like Uranus (about 90deg), what should I expect for atmospheric winds? I anticipate a stratospheric wind only, dropping to the surface at ...
In my world there is a rogue scientist who wants to wipe out at least 90% of humanity. He's has a sample of measles which are very contagious but he needs something new. Could he merge measles with...
I had a vision of a creature that touched things, and wherever it touched, it left a mark opposite to the original colour. For example when it walked across the grass the grass had red footprints,...
Take a planet with an atmosphere similar to Earth's but, say, 9-10x as dense. What is this going to mean for the performance and design of the heat engines that are so familiar to us? Higher oxygen...
I am a collector traveling from planet to planet, who believes that art is an expression of human emotion and feeling, and can come in all types of forms. Many greats, such as Picasso and Van Gogh,...
I want to have air and STP (standard temperature and pressure) around my spaceship. Other properties: Objects can enter and exit it without bumping into any kind of a barrier? In fact, there doe...
In a setting with multiple sapient fantasy races (ie, elves, orcs, humans, dwarves), assuming these races could interbreed and this activity became common, would they eventually reach a point of hy...
Let's assume that there is a lake that has formed from snowmelt and rainfall. The lake has never been in contact with other bodies of water. How might this lake become a complete ecosystem?
Biologically speaking, what would be the best real world explanation for a pyro, torch, fire-starter type mutation. Leeching heat energy from the environment might freeze dry your surroundings. G...
