Think of Saturn. In this book, some people travel to a gas giant with rings and find an ecosystem in the rings of a planet. It has predators and prey. It has plants and animals. Autotrophs and Het...
Suppose you had a tower-like mega-structure, rooted all the way into near-infinite geo-thermal energy of the Earth's crust, connected to the ocean such that water is not a limiting factor to the su...
Below the surface of Dalia, there exists a monstrous beast that eats humanoids alive. This creature is called the Tayan. The Tayan is 150 feet tall, and 35 feet wide. It nests itself underground, a...
In the middle of the night, while J. Random Human is sleeping, A. Hypersphere picks him hyper-up extremely carefully (so that none of his matter falls out in a direction he doesn't have), flips him...
Just a fleeting hypothetical that crossed my mind. Say that no flowering plants exist. I don't know why - say a world has been terraformed with various Earth species. Bumblebees are present, but fl...
I'm looking for a map of stars within a few hundred LY of the Sun. I'd like to be able to add text tags to stars, so I can name them within my SF universe. Then I'd like to be able to rotate the im...
What should conditions on an alien planet be like, if the aliens of said planet move 3 or 4 times slower on their home planet than they could if they were to come to Earth? (Gravity, atmosphere, et...

In A Canticle for Leibowitz, the Plains Nomads conserve water for their animals by men drinking animal blood and women and children drinking milk instead. However, since ingesting any decently size...
I'm designing an alien planet which is roughly similar to earth (continents, oceans, breathable atmosphere, plant and animal life on it), but i was wondering: Could a planet that is very similar to...
How Long? In the 1960s, unknown to most, the United States set up a secret base on the moon manned by an "extra" aboard each Apollo lander. NASA architects decided that the base must be built into...

I've been thinking on the concept of the human race dying off (the reason doesn't matter), but most of the other living species on the planet survive. Although we die off, the remains of books, the...

If there was a city using antigrav to maintain a position over Kolkata, and it had approximately the area of New York City (roughly 300 square miles, or 780 square kilometers), what altitude would ...
Is it possible for there to be a "solar system" of sorts with a black hole and a few suns orbiting around it? Could that system be stable and (if so) would it be possible for some civilization(s) ...
