In my world, zombies are quite common, and are considered a part of the wild life. Most of the usual flora and fauna are similar to those in IRL. I have three key questions, but I'll put the other...
Bird wings are made mostly of feathers, and there's about a million articles out there on that subject. Bats, on the other hand, have wings made largely of skin and bone. These are flexible, giving...
I want to write about a planet that has a high average temperature, but low enough to be comfortable. Just because of curiosity, I would also like to know the lowest comfortable. Additional Info:...
I mean can time be controlled within an area or even a small portion of space? I would like to mention time-bombs, which either reverse time in a radius of explosion or take time forward. Also nan...
I am trying to develop an alien species that could live on Titan and at first I supposed it would be easy with the species being able to use yellow, red and near-infrared wavelengths of light to se...
Context To revive the Carboniferous period of earth one man and a group of other scientists have been genetically engineering and breeding land arthropods into giant sizes and exotic shapes since ...
Question: What circumstances (theoretical or based on actual past events) could lower the global temperature on Earth or an Earth-like planet to an average of 30℉–40℉ (-1℃–4℃)? Conditions:...
So, awhile back I asked this question Reversing the rotation of the Earth, effects In it I said that, We can probably assume that Dr. Doofenshmirtz wanted this to happen quickly, within a day...
What is a flower or shrub back home is a tree in an alternate Earth, and vice versa. That is something worth exploring. For example, Taraxacum officinale can grow from stems typically up to 5...
My protagonist is an astronomer in a fantasy world. Ideally, what I want is software where I can specify some properties of this planet, e.g. orbital and rotation period, nearby stars, number of m...
If there was a planet half the earth's diameter, for which every other aspect of the earth was changed proportionally to keep the Earth's perfect ratio intact (including having the perfect orbital ...
I had an idea for a race that is humans alchemically fused with various animals. One of the sub-varieties is rabbit-people, who have the famed bunny fertility. How might the bodies of the women be ...
I'm writing something in which the main character has become a vampire, or vampire-like entity, due to the influence of a Lovecraftian horror. What are some things they, as a conscious person, may...
First post, if it isn't completely obvious. I've discovered this site by trying to "google" that question. Here's what I'm investigating: Long ago, pre-deluvian civilizations built ancient megalit...
I'm building a near-future world on top of someone else's older world with not-entirely-well-thought-out "elemental" magic. I'm willing to use "because magic!" arbitrarily to answer questions of ho...
Let's say that the aliens exist, do you think that they are smart enough to create their own Mathematics? Or even their own Sciences?
While it does not occur in nature, I have wondered if a sufficient amount of energy deposited in a sufficiently small space in a sufficiently small amount of time could ignite a thermonuclear deton...
We all know that the universe is going to die one day: all the stars will die, all the black holes will evaporate and life will be gone. But hypothetically speaking, if a super advanced alien race ...
Imagine if the Moon had its own moon. A moon (likely an asteroid) that lies within the Moon's Hill Sphere. I have read elsewhere about the fate of such a moon. Over time due to the Moon being tidal...
Presume a decade of darkness, after a several months of steadily shortening daylight. Assume that the temperature and weather patterns remain (inexplicably) fairly unchanged. Ten years later, whe...
For backgrounds sake, let's say that there are large, and I mean large beings living underneath the icy surface of Europa. Now consider this excerpt from NASA's page on Europa: One of the most...
Inspired by a brief comment converstaion found here. I would like to investigate the design and development of an alien species whose technological development did not include an understanding of ...
Cross-linked polymers are vitally important materials used all the time in modern life. For example, the resins used in composite materials are usually some type of cross-linked polymer. What typ...
I'm making a game which takes place in an asteroid field that is very dense - I'm talking close enough that one is able to jump between asteroids (provided you have some sort of additional thrust b...
What additional difficulties might the inhabitants of a gas giant moon face when attempting to launch spacecraft beyond their moon's orbit, especially beyond the planetary system? I presume that th...
