I was wondering if a moon Is in the center of two planets If the gravity will rip It In half or If a moon can rotate around both planets or if the moon manipulates the planets rotation
A planet much like Earth orbits a star much like the Sun, but with one difference: the energy from the star is magically transformed into sound within the planet's atmosphere. There is no longer st...

Recently, I found this map of Africa's paleolakes in the Imaginary Maps reddit: Finding this map was mere coincidence, but this map definitely interests me. Now there have been multiple what-if...
So in theory, I would want this planet to have the same everything as earth besides the radius (and anything that affects how radius plays into gravity). I know the density of this Planet X would h...
This planet's atmosphere has oxygen at a partial pressure that is breathable to humans, and the rest of the atmosphere is, at least, not made up primarily of Nitrogen (that is, it's not just Earth'...
In my last question, I have asked on how, once Mars has been terraformed, Terran species of plants and the insects on which the majority of them rely on would adapt to Mars's longer year. By far, ...

I want a character to get sucked into what she thinks is an FTL-wormhole-gate. While it turns out that the gate is indeed a traversable wormhole, it does not allow for FTL travel. The gate transpor...
Gray skin and red eyes is a common look for Dark Elves, and I have a similar race in my own world. But what would physically cause such an appearance? Hard Requirements: Must not be the result o...
Gravity does exist in this world, and so does air and clouds. But this creature only has enough weight to stay in the air without falling or being lifted up. It's big like a whale and it does have ...
A rare design I have seen in fantasy games is a wyvern or humanoid being with hand like wings to fly I'm curious if this is in any way a practical design and the reason something like this would ...
On this parallel earth all vertebrates received the ability to efficiently produce super strong materials from readily available minerals/nutrients in the mid Triassic. The specifics of these comp...
Exactly what it says on the tin. Kleeber the warrior is wearing a gambeson and carrying the standard adventurer's gear (leather backpack, 100ft of hemp rope, bedroll, spare clothes, waterskin, dry ...
Is it possible for an organism to evolve a capacitor if the conditions were right (carnivore that stuns fish, living in complete darkness, etc.)? What kind of challenges would there be to evolve so...
