I had this one idea of having the government create chips that monitor the thoughts of prison inmates as a way of preventing future crimes. At the same time still, give them a degree of freedom and...

In a near future setting I am working on, humans have built space-habitats and have established colonies on celestial objects such as Luna. Their spaceships cannot go faster-than-light and have the...
I recently watched this Kurzgesagt video exploring the question of what would happen if you had a black hole the size of a coin. To summarize the video: A black hole with the MASS of a coin wo...
The Setting I'm doing background work on a story involving a civilization about as advanced as ours materiologically. A significant part of their military operates along the continental shelf zone...
The situation: the good guys are attempting to infiltrate an enemy base, and cause mayhem either in person and/or by planting explosives and running away. They know there is a big dust storm on the...
How could the amount (total mass) of oxygen be increased on a planet like Earth (with a similar atmospheric composition), preferably by natural processes? For the sake of having a ballpark number...
I am currently trying to make a world that has casual interplanetary commutes with near future technology (within one century); so, to find a reasonable top speed for crafts in my interplanetary wo...
There is a group of people with about renaissance-level technology clearing out underground granite. They have no access to work animals. 700 men are working at any given time. Mining Using rena...
For a SciFi project I work on I have a space-station orbiting earth that uses an 8 hour 3 shift system for its staff. Each shift is assigned to one-third of the countries and organizations on earth...
Many questions on this site hypothesize about two planets in close orbit of each other, each developing their own civilizations. How feasible is that? Some 4.5 billion years ago Theia, a planetary...
Assume an Earth-like or super-Earth terrestrial planet in a state comparable to Precambrian or Archaen Earth. The atmosphere is mainly nitrogen and carbon dioxide, perhaps some methane, but very li...
So, I the question of what if a black hole hits the earth has been asked to death by various people, but what if the somewhat tamer wormhole hits the Earth? In particular, we'll say that one mouth...
I'm working on a sci-fi book, and a chapter I'm currently on is about a guerilla attack on a human city on the planet. The outer atmosphere is mostly CO$_2$ and methane. The aliens breathe methane...
In a very distant future people have survived by slowing the metabolism to extremely long timescales, reducing the energy consumption per time. It is causing thought processes and movements to be e...
Suppose we have an Earthlike planet, with a rocky moon orbiting it. Under what conditions would dark lunar maria form on its surface, and would they always be on the side facing the planet? For Ear...
So I was curious what would be the advantages and disadvantages to have 12 DNA bases? For example could it be used to store complex memories in an organism, could it cause very complex structure in...
Chthonian planets are gas giants that orbit their stars so closely, the intense heat from the star strips off the gas giant's atmosphere, leaving behind a tail of gas. This turns the gas giant into...
I'm writing a book and I want to use rail-guns for advanced space age factions in warfare. I would like to make them as realistic as possible so I did a bit of digging myself, but most of the inf...
This is a follow-up to Neutron Star mining. Assuming that problem can be solved, it would eventually degenerate to something similar to this case. And if it can't, white dwarfs seem like the next b...
EDIT: As it turns out the method I had thought of using to combat aging doesn't work the way I expected. As such I have rethought this question in more vague terms. New Question: Using current hyp...
We know from the International Pronunciation Alphabet (IPA) and the research that gave us the IPA, what sounds typically used in human speech (certainly not all sounds that can be made). This is al...
In the question of a biological cannon How would a Biological Cannon work? , one option was to use biological by-products for chemical propulsion of the cannon ball. It might have also been propel...
I'd like to explore some details on a so-called water-ball planet (i.e. a planet in the habitable zone of a sun, covered by a 100 km deep ocean). I am particularly interested where life could devel...
There exists a single solitary tree at the mouth of a small river. This tree is basically a fountain of youth, granting immortality to anyone who eats it's grapefruit-sized fruits. As you can ima...
