This idea comes up quite frequently in science fiction, but there has not been a question about it yet on Worldbuilding.SE. Is it possible that intelligent life was brought to Earth by an alien ci...
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?
Currently your work and life schedules fall mostly into 'day' and 'night', with a few areas breaking up work times into 3 part shifts, morning, evening night etc. Imagine we live in an artificial ...
It's always ~7:30 PM. Gravity and air are normal, and clouds and winds and storms exist, but there's no moon, and the sun is always just touching the horizon, without ever moving in the sky. The w...
I'm aware of hard radiations from space can wipe out life but I believe that would also causes the planet to be inhabitable for a period of time. Is there any other kind of energy that could destro...
Far into the future, humanity is largely split into 2 groups. The first group consists of space-dwelling humans, who live in enormous space stations equipped to sustain human life indefinitely, ...
If the moon had life and it progressed at the same rate as life on earth, including key points of technological discovery. When would we, on earth, have first detected them? Technological discover...
As a matter of course, a number of scientific articles and books have held speculation as to the possibility of life on a Jovian (gas giant such as Saturn, Uranus, Neptune, etc). Typically, this co...
Let's take our regular "Great Blue Star Whale", with a mass of about 10 000 tons. That poor, poor whale is reaching the end of its life for whatever reasons. (Damn you! Space whale hunters!). It w...
Is subsurface life possible on Titan (Saturn's moon) ? Temperatures on the surface are way too low to sustain any life (<-150 degrees Celcius) but since there is some tectonic activity, I was w...
If we made a large moon near Mars, the tidal forces would encourage the tectonic system to rev up again, and start up the inner dynamo effect. There would be volcanoes, producing a new atmosphere, ...
I have a world that has unexpected lifeforms detected. There are to-be-revealed reasons for it, but the way the ecosystem is set up is: Microbial life is abundant everywhere There is a single sp...
So, like my question says, I've been wondering if a rocky planet, that looks much like our planet from the surface (oceans, forests, mountains, ext) could be possible. I've read through a good nu...
I have a world idea (and definitely not the only one with such an idea in which the main location is a moon of a gas giant, that has life like on Earth. What are the effects of the presence of the...
The binary stars system is comprises of a red giant with 6 solar masses and a Sun-like star, the exoplanet is orbiting in the Goldilock's zone with a molten iron core which generate a magnetic fiel...
I have a world in mind that is essentially a planet-wide underground ocean. The planet doesn't have a strong magnetic field, so radiation on the surface is too high to allow life, but what I'm thin...
Inspired by this article about the recent discovery of a subsurface ocean. So now we know it has a liquid water ocean and a magnetic field. The subsurface ocean is also protected from radiation by...
Following this question, I had additional question of habitability. Assuming that life could exist on planet formed roughly twelve billion years ago, allowing complex life to exist as of seven bill...
