I'm curious what it would take to get a planet with so much free fluorine that you can have an atmosphere of predominantly or purely fluorine. I realize how improbable a planet like this is, so I'm...
Since gamma radiation consists of photons, just like visible light does, albeit on a different frequency, isn't there a plausible way that in, say, 200 years into the future, we could harness the p...
Is it possible that there might be a virus (of the giant, ancient, frozen-in-glaciers type) that is, for lack of a better explanation, double-layered? As in the first layer affects the host and the...
Background In an environment with little visibility/short line of sight, in a roughly medieval setting, people who wish to represent their business and guilds etc., choose do so using sounds/music...
I am working on a scenario that begins with an impact event. I have multiple questions, but I'll start with the catalyst for this world. Is there a type of impact event that would not be a global ...
If a typical human were shrunk down to be 3cm tall weighing 2.5 grams (ignoring all problems that would cause), would the blade of the grasslike plant described below be able to stop its fall from ...
For no apparent reason (this is a song, not a story, so I'm pretty economical with exposition) nearly every tetrapod on Earth has vanished, and water is gone from the oceans. Just sort of hand-wave...
Primordial Earth was buried in carbon dioxide. When life started, it was with algae using energy from the sun to crack the carbon out of carbon dioxide, with the byproduct of releasing the corrosiv...
An airborne disease with an incubation time of 18 years goes unnoticed, but spreads across the world. 18 years later, its "timer" goes off, killing all adults. Good idea (thanks, @Morfium !), but I...
I've been looking for information on this, but I haven't come upon an answer that could actually help me figure this out: Imagine a planet, inhabited by somewhat "human" beings, that has one sun-l...
Is this even remotely possible? Source Outline: Coral Polyps (along with their copious Calcium Carbonate excretions) are the individual organisms that make up the super-organism we identify as...
Is it possible to create a room-temperature solid made from 100% human blood? One of my stories features a girl who has the passive ability to block the superpowers of anyone in a 100-meter radi...
I was wondering what would happen to life, when an infamous epidemic plague would be able to infect and kill any imaginable plant, be it on land or in the waters. Would the lack of oxygen eventual...
If for instance in 2117 when we have the next Venus transit (Venus between the Sun and Earth). There was a huge solar flare or storm right on the line from Venus to Earth. Could this give enough en...
This is a very closely related question to my previous: Evolution of tree-dwelling species that will help predators find prey if prey species doesn't give it a bribe? The premise is the same, a t...
Suppose we have a Branching Timeline paradigm, in which time travel into the past creates a new timeline. Is it fair to assume that any probabalistic events which might occur might be very differe...
For space travel: would you need to recreate earths air composition? Or could you just get by with the top 2 or 3 main components, i.e. either 78% nitrogen and 22% oxygen, or 78% nitrogen, 21% oxyg...
I have an idea: can a moon float on the atmosphere of a gas giant, just like a piece of wood floats on the water? It is based on the following situation: The density of the atmosphere increases ...
The current technology around this subject is somewhat hard to gauge. For obvious ethical reasons, there is not a lot of empirical precedents. Also, given that it's subliminal, it is by nature diff...
So it's plausible that any planetary civilizations (alien or human) may have landfills. It is also natural to think that many planetary civilizations would die out, or migrate away from a planet. S...
Just thinking if it is possible to have a Fire-Freeze Planet? A planet with permanent Ice cover on one hemisphere while a hot terrain on the other side of it. A planet that may have moder...
So in many games you have regions that are bordered on all sides by impassible geography of some sort or another. This has always bothered me as necessary but also acts as a reminder to pull you o...
Most of the AI's in films/books/series seems to turn out evil or using destructive/harmful ways of achieving what they want in critical situations because they can't understand the earth's biology....
I'm writing about a small desert planet (about the size of pluto) that humans can live on. Is this possible?
This is a follow up to the creature 'griffins' I sort of created here: Anatomically Correct Griffins The idea of the final griffin was a small tree based species that will leap down on much larger...
