I have seen from various questions here (and from my research), that a Pangaea-like supercontinent would be very dry, with lots of deserts, since rainclouds couldn't travel a great distance inland....
One of my fictional planets is a lot like Venus. Tons of volcanoes, extreme air pressure, similar density. The volcanoes are active. There is 1 creature here that depends on minerals and acids. Wit...
My planet has an atmospheric density 12x that of earth with 0.8 Earth Gravity. Someone pointed out a while back that this would increase the wind strength proportionally. Now this is a problem as a...
I have some typical gryphons in my world. Bird head and wings, cat bottom half. Four legs and two wings. How crucial is a bird tail for flight? Could my gryphons be good flyers with just having a ...
I am writting a novel ( in a world where magic exists, and is evolving every second ) A lucky guy, found the notes of an ancient artificer on a training artifact. The artifact was very easy to mak...
I have scoured through the archives here and cant exactly find what I am looking for in terms of a specific setting I am trying to render in my novel. Let's say the world has built up so much smog...
Let's assume that sometime in the next year, we receive a transmission from deep space containing what appears to be blueprints of an alien genome. After extensive study and determining that the da...
Background: In the world of Krynn (Dragonlance) there was this worldwide catastrophe, the Cataclysm. What happened: Gods became angery to a single person, so they threw an asteroid at him, oblite...
I want to explore the possibilities of an alien species not much unlike that of known to Earth: snakes going through evolution in a way that made them able to reach the intelligence necessary to us...
There is an earth like planet, with similar mass, gravity, atmosphere and magnetic field. The main difference with earth is that it has a highly eccentric orbit (eccentricity 0.8). Let's say that ...
Suppose that a god has created a universe with nothing in it, except for a single, solitary celestial body. For simplicity, I'll call it a planet, although it most probably technically won't be. Fo...
It's 2020, carbon emissions are in decline but not fast enough. Oceans continue to rise at an increasing rate, so a plan is proposed to cut ALL carbon emissions: Cover the moon in solar panels (ta...
Premise; A magma/lava planet tidally locked around its sun. The side facing the sun is always erupting lava, the dark side is a cooled shell, which sinks into the magma beneath in a global whirlpo...
I read somewhere that the size of a planet can influence the number of pressure belts (the areas of high and low pressure that cycle wind, heat and moisture about the globe) How would you go about...
Alright, this is an edit of my previous question, in response to a number of urges to clarify it. I'll do my best to be clear and concise. How long would it take a spaceship, locked in geostationa...
I was wondering: what if a planet (such as earth) suddenly had all surface tension removed (mainly in water, because all carbon based life forms need it.). What would happen?
Thanks to enhanced space telescopy Earth has found some great candidate star systems for colonisation. But they are not yet ready to try sending people. There's no new physics. However, the cost...
Alright, so I've been doing some research on hypercanes, which are, in short, theoretical hurricanes that may have ravaged Earth in its ancient past, when ocean temperatures were much higher (at le...
There are a wide range of environmental temperatures located all around the world, from the low -90° C to high 60° C at the extremes. When looking at the core body temperature however the range i...
Could an alien underground macroscopic ecosystem including human sized plant-like organisms evolve around lava as an energy source? These organisms could use heat and/or light from the lava to synt...
I am writing a story for school about a human level AI. I want to have him be able to optimize and improve upon its own AI, but does this breach the Halting Problem? Thanks in advance.
Situation: a large terrestrial planet (a 'super earth', around 9 earth masses with a surface gravity roughly double earth's) with a mostly hydrogen atmosphere and ammonia oceans (pressure is high...
This cat looks like a normal Maine Coon to the unsuspecting victim. Except for one little detail: Red claws that inject a neurotoxin into the victim onpon scratching it. What would be the most app...
Humans have achieved FTL and have colonized several planets in our greater stellar neighborhood. While we have discovered several planets that harbor life as we know it, we have not yet discovered ...
Some species which reproduce sexually will replace one sex with (or add) hermaphrodites. The coexistence of males and hermaphrodites is androdioecious, females and hermaphrodites gynodioecious, and...
