I want to make a superhero that can control all forms of energy. From what I've heard you can do a lot like, manipulate time and space, open blackholes, teleport, shape shift, and manipulate matter...
Other than photosynthesis being an issue, if the Earth's surface became inhospitable and humans were forced to live underground, what biological changes would they be expected to go through to adap...
The basic question is: When is a location good enough to build a space centre on it? Some info to the function of the space-centre: The space centre has a lot of traffic, also humans. I imagine...
It's easy enough to figure out how a species might evolve a third biological gender in general (e.g. some sort of asexual drones/workers, ala insects). But what I want to build is a system where t...
Related Question : Can we 'beam' energy from the moon? I was wondering if instead of 'beam'ing energy from the moon, could it be possible to extend a power cable from the earth to the moon? If th...
Related to the this question about not going SPLAT. That one was for conventional travel through space at high speeds. Now I want to know about how things would work with an Alcubierre drive. I...
I've been hearing and reading about that solar flare in 2012 that could have sent us back to the 18th century, by causing huge geomagnetic storms which would have prevented (every?) electricity-bas...
Assuming that you had: some sort of amazing power plant on the moon that can create an unlimited amount of power a similarly amazing solar panel on earth that can receive an unlimited amount of p...
Instead of trying to tether the Moon, can we somehow harness the Moon's kinetic energy, the same way we do wind? If so, how is this possible?
Could you build a ring around the earth, so that it would just sit in the sky? I'm not talking a geostationary orbit of rubble like the rings around Saturn, but a solid structure just high enough t...
Background story: In near future (max 10 years from now) mega-rich person suffers yet unknown disease. He obviously employs every doctor possible and spends loads from his fortune on researching, w...
Imagine a species (the cause is largely irrelevant - could be alien meddling for all I know) that is Homo sapiens in all except one detail: they have additional organ which is kind of like gills - ...
I am not a writer. I have never written any story and I have no idea of what it takes to get this idea into any meaningful narrative. It's more of a thought experiment for me and I formally give th...
My time traveller has a maybe 20-minutes-into-the-future smartphone and laptop. They can store large amounts of data, on the Petabytes level or higher. The time traveller can effectively store the ...
In a video game series called Portal, we are given a gun, which shoots two portals: an orange one and a blue one. These portals have the following properties: Anything that goes into the orange ...
Visiting the Worldbuilding site plays with my creativity and imagination. So I am going to describe the dream I had: I am member of a different (alien) culture, from a different star system. Also,...
A question about portals from the 'portal' games. In the games, pairs of flat, identically sized and shaped, effectively for simplicity rectangular, portals, that lay flat on surfaces, link two pl...
What underground, for example burrowing or tunnelling creatures on earth, have underground organisation/societies, that are intricate enough for interesting narrative features, for example friendsh...
What are realistic time-schedule expectations for far-future terraforming and developing earth-like plant and animal/fish/bird populations on distant planets, by means of robotic space probes with ...
Apologies; it just didn't seem like an appropriate question for Earth Science or Biology. Let me know if I'm incorrect. Maybe Physics? If all the ice, permafrost, ice caps, etc. melted due to glo...
So the world has been destroyed. Pick your poison. We have probably 300 different scenarios lying around here somewhere. What's Left: The world is a desolate wasteland, dry and crispy and barr...
Gas giants can generate heat via the Kelvin-Helmholtz mechanism. It's oft-repeated that Jupiter actually generates more heat internally via this method than it receives from the Sun. Scale this mec...
Characteristics: has close to 80.000km in diameter The atmosphere is composed of: -30% hydrogen (cold gas planets have hydrogen but it makes sense it exists in a rocky planet?) -20% oxygen -...
What if, sometime in the next say 600 years, humanity develops a device capable of manipulating the four fundamental forces in the area around it. (For example, a handheld device could work in a ra...
I've been wracking my brain about a world I'm writing in, how to make some group of regular people able to survive in space for extended periods with or without a suit. I can reduce the amount of t...
