So humanity has decided to reach for the stars, they can't get anywhere near light speed but that hasn't stopped them. The plan is to create a self sustaining ship and attach it to a large sungraz...
One of the things that affects the color of the sky is the wavelengths of light that the star emits, like the image in this question. Here is the image again: If you are standing on a circumbina...
Real parasitic plants target only plant hosts and in certain species fungal hosts. How plausible are parasitic plants (or algae, lichen, or other photosynthetic organisms) that targets animal hosts...
It's a common trope that during the Cold War (and afterwards) America, the UK, the USSR, and sometimes nations beyond these developed super spies, capable of acts of espionage, sabotage, and direct...
I'm writing a story where some children (age 5 to 16) are abducted by aliens and now live on an alien planet. The atmosphere is similar enough to Earth's that the children don't need any special su...
In the marvel universe mutants are much more fortunate than in our world; they often have extremely useful powers; ranging from telekinetic abilities to wings. As interesting and plain fun as this...
I've heard that the atmospheric pressure on venus is 90 times that of earth, but I don't know the melting point of $SiO_2$ at 90 atm nor at what temperature its vapor pressure hits 90 atm. Basicall...
On my planet, the only animals are plankton, krill, shrimp, etc., but no fish or land animals. The colonists on this planet have brought equipment and embryos from the home world, but the only free...
For a complex world-building scenario I want a habitable moon orbiting a habitable earth-like planet. The habitable moon should allow for flora, fauna and landscape as similar to earth as possible....
So there's a planet that is used as a farming world (food) for its system. This planet has a single, Mediterranean sea-sized ocean on it and lacks any other major surface oceans (he hasn't excluded...
I was imaging a system which has a black hole, a star and Earth like planet. The star and planet orbits around the black hole, but the planet has same orbital period as the star, which is a "quasi ...
That title is really long... but the essence of this question is basically asking whether a complete combustion flame would be more destructive(burn things faster? and spread faster?) than a incomp...
My question is pretty simple, all the details about the planet are pictured below.
Of all the creatures in Hatjörn's dominion, there is none as peculiar as the Murinae Spirita, the mean booze-rat. A vermin so resilient that has developed the most wondrous means of defence and...
Assume a world with no multiverse theory, just a single unbroken timeline. If you were to go back in time to the town your parents lived in on day of your conception, the air displacement due to yo...
Disclaimer: This question is the third of a new series of questions of mine about introducing hexapeds to the fauna of my conworld. There are/will be other questions addressing i.a.: characteristic...
There is a alien species known as the Titanians. The Titanians are organic biologically, but of a alien biochemistry much more cryophilic and oily. They drink ethane, breathe oxygen (you can ha...
So in (a lot of) sci-fi we have magic gravity that gives up and down and layer-cake decks, and nice and easy set design for the TV studios. I'm actually pretty much okay with this, but what rubs me...
More specifically, I've had some debates with a friend on how a planet with low oxygen would work. Of course, it's his IP so he insisted on low oxygen, and we're hand waving aspects of it. But for...
I Was playing space engine and i was looking for a planet like Earth for quite some time and then i stumbled on this beautiful world covered with liquid water which orbited a main sequence star wit...
What if, through advanced psychological techniques and enough knowledge of a human mind, could someone construct a building that when a person lives there for an amount of time, could subliminally ...
Evil Wizard got his hands on a Handwavium Wand, and wished the Earth's magnetic field no more. Now the surface is vulnerable to solar wind, solar radiation and cosmic radiation. How long will it ...
What would colonists building a base on Europa use for building materials? I am interested in habitats in three locations: on or just under the surface bolted onto the underside of the ice sheet...
What colour will planetary rings made up of dust and rock (not ice) appear to be? Would there be a difference looking from space and from the surface? More importantly, how will the rings affect t...
