A Dyson Laser would be a spherical swarm megastructure arrangement of robots focusing mirrors directing sunlight towards a particular planet in a system heating it with enough energy to melt it. T...
What would happen if an extremely advanced race removed the metal (everything beyond H and He) from a star. Would the star still function? Would it change in appearance or properties at all?
Is it possible for a planet's moon to always rise at the same time of the night? And in this way be used as a timekeeping device? What if there are two moons?
An Orbital is a miniature ringworld used by the Culture in Iain M. Banks's Culture series. Wikipedia has details on their basic structure, but to simplify, the main difference from a Niven ringworl...
My understanding of the hypothesis is somewhat hazy, so I probably have gotten something wrong. But as I understand it, the total energy density of the universe is either very small or exactly zer...
Given advanced enough telescopic technology, would it be possible to detect that a planet in the order of 50 light years away is inhabitable? (i.e. without having to actually go there) I'm just lo...
For the sake of simplicity, my species is similar to humans but far more advanced. We will also assume that they live in a solar system similar to ours, and that they are advanced enough that they ...
This will be a companion question for How plausible is my monster?. My previous question dealt with a story treatment for a hard science and realistic take on Kaiju/ giant monsters. While that sto...
Here's the scenario: animals on a world with an atmosphere with a significant amount of a certain gas is able to store "air" into a transparent growth (like a crest) and, with an electrical chord i...
Usually, forms of life are associated with organisms like humans, plants and animals. The probability that such can evolve in an environment is very low due to the many constraints that have to be ...
Description : Even in the ⅩⅩth century, biological warfare was studying only existing diseases. But recently we're able to modify viruses in order to cure genetic impairments. Would it be pos...
So a rainforest creates a positive feedback loop"”vegetation creates evapotranspiration which encourages rainfall, which in turns encourages more vegetation. If you wanted to badly enough, could y...
Short question, what events would induce the evolution from hands of 4 fingers and 1 thumb into hands of 2 fingers and 1 thumb like the hands of Yoda in Start wars?Would be 2 thumbs and 1 finger be...
Why would an non-Eusocial animal have a caste of sterile individuals? Formicidae and Apoidea have sterile workers,but those outnumber the fertile drones and princesses or queens. In another anima...
I am a clockmaker: I work with time and can control it on a small scale. One of my powers allow me to return some minutes back in time after having experienced my death, but I remember everything ...
If a tribe of homo evolves into a wild animal that doesn't resemble at all a hominid, is there any chance for this animal to evolve back to the original humanoid shape through atavism/other means? ...
Inspired by Mapping the far side of the galaxy, I wondered how it would be possible to create a real-time map of the entire universe. As that question dealt with the issue of a one-time travel to ...
I'm working on a story that deals with an inordinate leap into the future and was wondering what leaps and bounds in science the human race may have reached by then. So here's what I'm wondering: ...
So, I just had an idea inspired by This question here while simultaneously listening to a video about language... Could we make a sort of International Phonetic Alphabet for Emotions and States of...
Using pre-industrial era technology how does an intelligent creature create the perfect illusion that reproduces vision,sound and touch sensations and make them seem perfectly ''real'' from the vie...
If your blood pressure ever falls below the ambient atmospheric pressure would it be possible for you to bleed. Because if blood pressure was less than that of atmosphere air would move in if you g...
We all know (or know how to find) the "rocket equation" that drives the design of a conventional rocket, and we've gone over such things as "specific impulse" and the difference between fuel and re...
Superconductors will be a revolutionary enabling technology for many aspects of space construction. One such use is a magnetic field to protect a craft from solar activity, in the same manner that...
Say if a planet had either no greenhouse gases or a small percentage of a certain greenhouse gas (roughly 5% or less) in its atmosphere, but all other elements in the atmosphere could support life....
I am creating a fictional fantasy (Medieval-ish era) world. The area covered by my map is fairly large, and contains an ocean, mountains, plains, lakes, forests, swamps, etc. It's pretty much all t...
