What would, roughly, a scientific research station look like on a gas giant? Use Saturn as a baseline. The station would float because of a "balloon" carrying nothing. Vacuum is the lifting "gas", ...
I just spotted this article about a metal foam that stops armor-piercing bullets as well as radiation. It's a press article, not a scholarly paper, so it may be complete bunk. And rifle bullets a...
I am trying to build a world which has a bit larger gravity force than earth, 1.25g. And I was wondering which impact could this have on its geology and life evolution. I think that with a higher ...
The world is divided in several factions. Among them : Insects and Humans. When I say Insects, I don't mean insects : insects are the little creatures with six legs while Insects regroup all soci...
A volcanic island can obviously come into existence quite easily and swiftly by natural causes, as evidenced for instance by the appearance of Surtsey off the coast of Iceland. However, people have...
I was thinking of a lifeforms that would have a brain more similar to that of a quantum computer than an ordinary brain. I was thinking the brain would use something similar to qubits that could be...
I'm trying to come up with a scenario involving a mining base built on a planet that may only be approached from the shadowed side; the star (or other body) allows only that narrow lane of approach...
It's common knowledge that one of the things that makes stealth aircraft so stealthy is that the body is covered in a skin of special material that interferes with radar. Would it be theoretically...
Consider a very conveniently placed asteroid in orbit around the earth, and we hang the space elevator off of that. It doesn't have to be at the geostationary altitude but it would probably help if...
So I'm writing a story set in the close(ish) future(say 2130), and space debris is starting to be a real problem. Stations in orbit are constantly having to maneuver out of the paths of orbital deb...
Some days ago I had a discussion with a friend about possible alien life forms. He was stating that there anywhere could be lifeforms that do interplanetary or even interstellar travel by jumping ...
So I am trying to make a sci fi story and I wanted directed energy weapons for starships besides lasers and plasma. I heard that a neutron particle beam weapon could be visible, but could any one c...

I have devised an alien species for a universe I am working on. They originate from the same planet as my high-pressure creatures (What would happen to a high-pressure creature in a low-pressure at...
In my world (set in the near future - no magical tech), every child after reaching the age of 1, is sent to study for 15 years in a centralised location shared by the entire world. With some playin...
In a short sci-fi story i am writing, Earth has a shadow twin. A planet with the same chemical/geological characteristics as Earth and wildlife very similar (but different species because evolution...
Mercury temperatures varies from −173 °C to 427 °C , though temperatures in the poles are always below −93 °C. To have a reference, the lowest recorded temperature in the Antarctica was -93°C ....
My space colonies are mainly located onto large, partialy terraformed moons in our solar system. They still travel using rockets but due to their vessels' large size they need very powerful propuls...
This is based on the notion of adaptive radiation, a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environm...
Everybody, even those who are complete beginners in the field of Astronomy, know Io, the cryovolcanic moon of Jupiter that looks like a burned pizza with skin cancer. Volcanoes constantly spit out ...
Let's say that something horrible has happened and a Mars-sized planet is knocked out of orbit and is hurtling towards an Earth-sized planet. How much time will they have? How will this affect the ...
