Could life originate on planets outside the circumstellar habitable zone (CHZ) where there is very little exposure to sun (like Uranus). If so what kind of energy source would they depend on. Coul...
This post-apocalyptic environment, as narrated in the book, depicts a world where most if not all animal life has been abruptly killed, and similarly most vegetation burned out. After the disaster,...
What is the best method for creating a visual that mimics aerial photography for a fake island. The desired quality is USGS standards for actual aerials, preferably 2 foot aerials. The end product ...
Considering that the oceans are rising (and that humans don't seem too keen on doing anything about it) and that population is growing exponentially, is it plausible to imagine that in a not too di...
I am looking at different ways to destroy a planet. I am assuming the planet is of a similar size and composition to the Earth just to keep things simple. I am starting at boiling the atmosphere t...
Take, if you will, a sci-fi setting in which power is cheap and handheld energy weapons (blasters, lasers, plasma rifles, that sorta thing) are common. In this setting is an isolated community bas...
Given a planet about the size of Earth, and a moon the Size of the Moon, how could one destroy the moon without flinging the fragments onto the surface of the planet or into outer space? How can o...
We lived through loads of questions regarding aquatic races, so buckle up, I am going to gather some ideas around insectoids. The homeworld and race This race lives on a planet which has lower g...
What would cause an area to get continuous rainfall (a la Blade Runner), and what implications would that have for other parts of the world? Ideally I'd like to hear about both natural conditions ...
And could it look anything like the universe we know? Don't get hung up on the terminology. In general, you seem to see through it easily, so I don't want any more answers mentioning that. I'll sa...
Question is ultimately asking why would we do this? A few parameters first... Technological: Our current knowledge of physics is correct and there is no such thing as faster than light travel, ...
Say we had a planet which was a gas giant. Is it possible that at the core of the planet where meteors, asteroids, and comet debris had collected that there could be a layer of atmosphere similar t...
What would be the major changes to our bodies if we were herbivores? Would our bodies be weaker because they were not getting any protein from meat? Would we be completely different? (Probably, I s...
As you see my other question What would be the major changes to our body if we were herbivores?. Instead of being herbivores, what would happen if we were obligate carnivores?
What kind of asteroid would it take to hit our sun out of its current position, even by just 50 meters? And how big does it need to be in order for it to do so? Would it continue to travel throug...
We've discovered stars that are contact binaries. This means that they orbit so close together that their photosphere reaches through their Roche lobes and links the two stars together. This sta...
Thanks to the recent discovery of handwavium "¡ filaments that can in principle be extruded to any length, we will be able to build space elevators sooner than most people would expect. The inte...
Pretty self explanatory question...can the Cube Earth described at the link below support a spherical core and a magnetic field? How would a civilization that has been living on a "cube" Earth di...
First see this great answer on considerations when making a calendar. Consider a human colony on our own moon. Let's assume that the colony is influenced by the Gregorian calendar. Let's suppose t...
What conditions would have to happen to re-animate a mummified person to come back to life with consciousness fully restored? What would the conditions of the mummification be and biological/techni...
Missing magnetosphere on Mars keeps popping up. Most likely caused by Mars core being cold, mantle not bubbly enough. Mars mantle is dormant, core does not move. What would be good way to get it g...
Another question based off of this one here. Let's say on a cube styled Earth-like planet, there was a similar race to humans. If the differences in the planets were minimal (besides, you know, the...
I was wondering what would happen if you attach 2 Huge ion engines(I mean really really really huge) to planet earth. They should be attached on the north and south poles. Are 2 huge ion engines ...
What would happen a volcano the size of Australia were to erupt? How high on the extinction-list would it rank? Would it be above the asteroid that hit Earth and killed the dinosaurs? Which known...
On earth, we use a simple but effective coordinate system which determines position unambiguously on the surface (GPS achieving accuracy within 1 meter, which speaking as an engineer, is a remarkab...
