As the title says, I'm wondering if a species could theoretically boost an asteroid near a planet for easier mining access. If this was to accidentally crash into the original planet could a habita...
Scenario: A colony of 20,000 is founded, and has no access to any further inhabitants. Assuming this colony is humans of varying traits (genetics such as skin color, eye color, etc) with no single ...
I'm continuing to work on my map, and one thing that's giving me difficulty is figuring out the geology of a region that I wanted to be similar to the Ethiopian highlands and African rift valley. T...
Another user's answer to a recent question, specifically the way it was worded, gave me a vision I cannot shake. Our intrepid adventurer, Joe A. Venture, is making his way through a subterranean n...
From: https://en.wikipedia.org/wiki/Multiverse The multiverse (or meta-universe) is a hypothetical set of various possible universes including the universe which we live in. Together, these u...
I was thinking about people who once told me that I must feel the rain earlier than them (I'm tall). So I thought of a world where the rain falls so slowly that the humans of different size living ...
I want to have my aliens have a culture that clashes with human modern culture and one way I want to achieve this is having some extreme sexual dimorphism. For these aliens the sexual dimorphism ...
Can two objects solar powered, equal in weight, traveling on the same orbital path in the opposite directions propel each other to intersect on the opposite side of the Earth in alignment to propel...
My idea has been a colonized planet or moon with incredibly strong winds so that life is only possible in deep valleys protected from the wind. I recognize that wind is primarily driven by tempera...
As many here likely know, one of the factors that make both Mars and Venus uninhabitable to humans are their lack of a magnetosphere to keep solar winds out. In the setting I am working on, I want...
What about the atmosphere of earth makes green the best color for plants, and what would have to change to make blue the best color? The fact that these changes could not happen on earth, an so wou...
One of the veggies that my Keplerians grow is peppers. I have heard of some sweet peppers cross pollinating with hot peppers making the sweet peppers hotter and the hot peppers sweeter. However tha...
Everyone knows that water is necessary for life because it is such a good solvent, but could a lifeform use water vapor as a solvent instead of water, or any other gas that works a solvent instead ...
Writing a science fiction where the air outside is not breathable for long periods of time. Some characters get high from the air, but large amounts of it cause the user to become paralyzed or blac...
What would Germanium based life look like and what conditions would favor it. I know that it's not that common but I am going to handwave that. What would be the resulting look for such a lifeform...
I haven't been here in a while but I got another question, Would it be scientifically possible for sunlight to cause a zombie to self combust into flames? And if they would only self combust if the...
The situation is the usual, we have lots of junk metal lying around in cities, great but not impossible difficulties with logistics (meaning that a few railroads are in operation at immense cost, b...
In an alternate timeline, Ceasar lives, forges an alliance by marriage with Egypt and dominates the entire Mediterranean. He then performs a raft of economic and political reforms that basically sk...
Are there any such world elements that would seemingly randomly cause creatures to faint for extended periods of time, ranging from a few minutes up, but revert before they started suffering perman...
I'm building a world that orbits close in to an M-Dwarf sun. I've figured out a bunch of the physical parameters of the world, I just can't quite get a solid handle on my tides. I know my tides wi...
Lately, I have been working on the way a group of humanoids vocalizes. In the anatomy of vocalization, I have recently asked about and explored some variation in vocal cords. The hyoid bone typi...
It is a somewhat common limitation of spaceships in some universes, that they cannot go underwater. They can land on the planet, take off into orbit, hyperdrive into the next star system, but they ...
Piggybacking on this question: Could soft matter infused with nano or pico sized magnets be used to clump together so that we could create environments with it? ...So we have a planet that has low...
The smallest type of dragon in my world is a bipedal dragon about the same size as a moderately sized bird, maybe about a falcon. In addition to its breath attack and high intelligence, this little...
From what I've read, planets orbiting red dwarf stars would most likely be tidally locked. Under what circumstances might this change? For example, if a planet had been the recipient of some kind o...
