Is it possible for a earth-like planet to orbit a neutron star & have intelligent life-forms, even if said neutron star 'moves' through different galaxies? as seen in this video - https://www....
Setting: Western world nation, Earth as we know it, May 2016, Gregorian calendar. Eccentric billionaire, large multinational corporation or similar; lots of money, and ability to enlist the help of...
Imagine an Earth-like society that has developed into the digital age. They have computers, the Internet and most of the conveniences of the modern age, but they still use a significant animal work...
A large group of people has been banished from Earth and punished to scrape out a perilous existence on a strange planet. The planet has breathable atmosphere, and consists of an immense ocean teem...
In an alternate Earth (or even in a pos-exctintion future), suppose intelligent but primitive humanoids 1/10 the size of humans inhabit the planet. They don't coexist with current humans or have ac...
I have a parallel universe very similar to Earth but with a society with the technological level of Europe during the Middle Ages. I want this parallel Earth to be one big continent, one giant land...
I'm writing a setting for some fantasy novels, and came up with an idea about weather and climate. The world I'm imagining has an elliptical orbit around a binary system, giving it basically 2 st...
In a world I am working on, I have a wilderness-living, social, group-living species that for various reasons lacks access and ability to anything resembling modern medicine, including vaccinations...
Not too far off in the future, maybe 20-50 years from now, an anomaly is detected a little ways outside our solar system and it's like nothing we've ever seen before. Researchers begin studying it ...
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...
Could an unmanned solar plane go not only above the clouds, but also so fast that it always is in the day-side of the planet? A solar plane flying above the clouds receives sunlight $12$ hours per...
If the moon started to move closer to the earth, for e.g. one meter per year, I suppose that it would be accelerating towards the earth and then, eventually, will crash to it. I suppose that if it...
Imagine the population of our planet is given free (almost) and unlimited energy. What kind of technologies would go mainstream which are not feasible today due to prohibitively high energy requir...
If half the earth was made antimatter and contacted the other half all at once, would the resulting energy be enough to "destroy" the observable universe? I did some math based on the mass of the ...
There have been a few questions about an intelligent avian species lately and they have gotten me thinking. It seems to me that it would be hard for an avian species to evolve to be more intellige...
I've been designing a world and wanted to base it on a rather interesting cosmology proposed by the ancient Greek philosopher Philolaus. He was a very early opponent of geocentrism, believing that ...
I know about humans, and how we have adapted to different eviornments with skin and hair color, but I want something a little bit different for my creatures. They are amphibious humanoids, and live...
If there was a majority of land on earth (66 percent land), how would it affect the animals and plant? Lets say somehow earth has been created with 66 percent land and 34 percent water? Would our p...
Would it be possible to have a planet made up of about 60-70% water with no landmasses larger than Australia? I would like this planet to be as earth like as possible, but I'm open to changing aspe...
On an Earth-like planet, there is a massive plateau, standing more than 1km high, and the breadth of a continent in the middle of an otherwise ocean planet. I know there are climactic issues to th...
Let's assume that the earth has stopped spinning. To be clear, the earth did not end up being tidal locked with the sun, but instead, it would just stop rotating around its own axis. This should re...
If I understand correctly, it's highly likely that the planets in a twin-Earth binary planet system would be tidally locked. But is it totally impossible for them to be much farther apart"”say, at ...
If there was to be a habitable planet, similar to earth, but with varying gravity at different points on its surface - lets pretend that it varies from .8g to 1.2g - what sort of terrain or form wo...
Imagine a scenario where the moon is not tidally locked with one side facing the earth but where it is able to rotate about its own axis. This could be due to a larger distance from earth or a mild...
I have an alien species that is my pet project. Now I'm to reproduction, which I have a specific idea for, I'm just not sure exactly how it works. My creatures are aquatic, and everything goes on u...
For fun (and for future evil diabolical schemes) would humans have the ability if given the finances and resources, to use some kind of massive wrenching system to pull different continents togethe...
Given the existence of neon kittens with: the internal properties and mentality of normal kittens bioluminescent fur. What evolutionary process outside of intentional human breeding/gene manip...
Given a "parallel" Earth-like world with 9 days to our own 7 days (ie, each day is around 18 hours, 40 minutes), what other differences would one expect/require to be otherwise "normal" and habitab...
I have two binary pairs of planets in a planetary system. All of the planets are habitable, and similar in mass and composition to earth. Each pair is identical, or nearly so. The planets are tidal...
I've seen related discussions here before so thought I'd share this idea. It is believed to be the only realistic (doable) method an individual or small group could use to apply such force upon Ear...
So here's the premise: We have an Earth-like planet, with a civilisation at roughly the same state as ours today. Scientists have been monitoring the atmosphere for centuries, what with forecastin...
I need an event man-made or not on Earth that can generate consistent earthquake that never grow weak, sky is the limit meaning any astronomical events will be ruled out. My story can take place du...
If all, or most, fresh water was frozen due to temperature drop over the space of a few generations, what would be the effects on living organisms such as humans and animals? Take in to considerat...
Following the answer from this link and assuming this is the best choice from the lot, if we had leave Earth right now and inhabit another world in a different planetary system, how would we humans...
It's just another average day in the life of modern day earth. Suddenly a transmission from orbit washes over the planet! Oh no! An alien race, calling themselves the "Thull", has suddenly arrived ...
Is there a way for a moon to usually appear relatively similar to our own moon, but occasionally appear much larger from the planet's surface without causing natural disasters due to extreme gravit...
Following up the ideas given in this question, we introduce a new gas to the mix of air. Meta: Assume an Earth-like planet. The proposed change is a pre-development change (meaning it's there sinc...
This theory, what I call the world shift theory, states that the Earth's original orbit was solar stationary at one of its poles constantly facing the Sun, building, over time, the magnetic poles. ...
I have a planet that I want to have a greenish atmosphere. I've heard in a few places that chlorine gas has the potential to make the atmosphere greenish, but also to kill humans. So, the question ...
A few years ago, an isolated tribe was found in the middle of South America. They seemed to be a normal tribe, but near their village is a lake with a special property- you can breath underwater in...
I am somewhat new to worldbuilding so forgive me if I am not as clear as I could be. I have created a continent, but for relate-ability sake, imagine the US and Mexico, but where the Yucatan Peni...
Right now the Earth rotates around the y-axis so East and West replace one another. What would the affect be on Earth's seasons if it rotated on either other axis? The first is the Z axis, pointi...
Related to this question, which deals with the no-papers visitors. However, in my case, instead of a character with no paperwork whatsoever -- we're dealing with someone from an alternate reality ...
I am building a fantasy world roughly the same size, elemental makeup, and atmospheric composition as Earth. In this world, there is an island (about the size of Australia) known by outsiders as th...
With today's technology could mankind create a system of rings similar to Saturn composed of different masses of water particles and silicate minerals that would freeze? How could mankind accomplis...
Bangladesh, like a lot of other third world countries require an awful lot of work to become, 'first-world' ready, thoughts we take for granted are condemned in such societies, but if they were to ...
Scenario run-down. Several billion years from now, Sol has finally exhausted its hydrogen supplies and has entered the red giant phase. It has already been increasing in lumosity for some time and ...
Does the position of the sun in a hollow earth scenario affect the way light scattering would "color" the sky? My understanding is the reddish-orange color during sunrise/sunset is caused by the ...
Let say a asteroid hit earth and you survived in a bomb shelter. How long would you have to stay in that bomb shelter before it was safe to leave it? How would earth look when you got out from the ...
I'm building an RPG world and the ice caps are rather large. How big of an effect would it have on the climate and seasons of said world? Would it be slightly colder or would it be similar to an ...
