So I have a brain parasite that needs to enter the skull of a host organism (in this case humans) with the least amount of effort, but is too large to enter through the circulatory system and must ...
Would it be possible for a moon that receives a lot of tidal heating from its gas giant parent planet like Io to develop intelligent life? Assuming moon is big enough to support an atmosphere and i...
In my fantasy setting, dreams are located in what could be called a parallel dimension - commonly known as "The Void". Some people are able to develop powers related to the Void through long traini...
Scenario: In my Evil Overlord plan, I release a poison into the wild which should kill all humans. However I made some sort of mistake in my poison design and I killed all Vertebrates bigger than 0...
First the situation, then the question. Here's the situation: An Earth-like planet had a civilization similar to ours, but when it emitted its first radio signals, a nearby alien observation post ...
Thinking of terraforming a localized region, how (if possible) can we create an artificial high pressure zone, whether practical or not, Initially I thought, perhaps we can arrange heatsinks to i...
Suppose humans have developed the technology to travel between star systems. This might be some science-fiction method like warp drive, jump drive, peanut butter drive, hyperspace drive or whatever...
A common feature that we consider to be alien is the eyestalk and rightfully so. To my knowledge the only vertebrate that even comes close to having eyestalks is the hammer head shark (if you can e...
Could a world with no animals whatsoever (not even insects, no humans, etc) still have plant life? These plants do not have to include all the plants in our world, or even any of the same plants. I...
Let's say an alien species discovered Earth and wants to land here and establish contact, however their homeworld's gravity is only 46 percent of Earth's, Would it be possible for them to be able t...
Small vs. Large! If you had nearly the same creature, and the only difference was size, what advantages and disadvantages would large size vs. small size have--beyond the usual--reaching leaves mor...
If dolphins came out of the water again and evolved into something approaching human intelligence, how would that look, taking into account their physical characteristics and what happened evolutio...
How scientifically plausible is this? A giant, self-aware fungal supercomputer made or evolved from something like the Blue Mountain honey fungus or maybe a slime mold of a similar size? Could some...
In a comment to this question imallett brought up the idea of a gas giant spinning so fast that the air is moving at near orbital velocity. In Mission of Gravity Hal Clement has Mesklin spin so fa...
Some months ago I made this thing, it doesn't have a name.So let's just call it Jonathan like my brother. Basically a lizard in erect posture with the head of a mammal, two ''tentacle'' antennas i...
What modifications would be needed for a mammal, bird or reptile to work with electricity? For work I mean mostly think and move, for example it would need to eat in order to repair it's body, gro...
Given an unlimited time to evolve: what are the best ways to make any wild bovinae immune to its natural predators like the classic big felines (lions or tigers) and most reptiles (crocodiles or Ko...
The potential story concept I have needs a tattoo that can change colour. I was wondering how possible that might be given small advances in current technology. From research I've found the 'blac...
Assuming we had a gas giant instead of Mars in our planetary system. Everything else stays the same. Which long-term and short-term consequences for life on Earth would I have to take into account?
I'm currently enamored with the idea of having a species of living, sapient stars (called "astrae") as the firstborn children of the gods in my space fantasy setting. Magic exists in this setting, ...
I'm currently working on an idea for a ring world. Thus far I've worked out the following things: Radius of 1 AU Width of half the circumference of Earth 2000km high walls across the rims to keep...
Suppose humanity found a rocky planet outside the solar system. It is in the habitable zone of its star, has breathable air, clean water etc. A true paradise. Only problem is, its surface gravity ...
If on a water covered planet, an aquatic species such as the merfolk evolved sapience and now wishes to go into space, how would their spaceship take into account the lack of land? How would a spac...
I have seen some questions asking whether some atmospheric compositions are survivable for humans. Most of them focus on long term survival, as in people being able to breathe indefinitely without ...
The idea of a collective consciousness (or anthill) species is pretty simple; instead of cells tissues and organs you have ant-like creatures, all making up a larger creature. This is different fro...
