I've read a lot of questions about the specifics of meteor impacts on this site, but strangely this one seems to still elude me: Assume a meteor of sufficient mass and speed to wipe out human life...
In my world a space civilization is colonizing a massive solid planet. The planet has an extraordinarily fast rotation. The gravity is severe at the poles, making life impossible, but life flouri...
continuing from the question I had asked yesterday, I have had another query come to mind. For my humanoid alien species to possess horns, it would surely put forward the risk of being the shortcut...
Caulerpa taxifolia, an algae species popular with aquarium owners, is the largest single-celled organism known to us as of today. It is notable for being able to regenerate from any part of the b...
Can we go from this: to this: Suppose over millennia (or as long as it takes) humans on Earth are artificially selected by aliens to be big and healthy. Is there any theoretical reason that ...
So, let's say a group of survivors tie an immortal being to a young tree sapling. The immortal does not need food, nor water, so can survive indefinitely. After about 100 years, could that young ...
Background: The creature is bug-like, and similar to an armadillo in size. Its diet consists of metal, and is found underground in large colonies. It uses the metal it ingests to: Enhance it's s...
I am currently working a humanoid roughly deer-like species in a sci-fi roleplay setting, and one of the developments I have had with such species has me stuck trying to explain it in a way that ma...
I have dragons in mind for my world, but I'm trying to find logic in how would a medium-sized anything fly off and still be a danger to humans. So far, I have a lizard-like cheetah with wings, ho...
This question is pretty straightforward: What is the minimum and maximum distance for a planet to be in the habitable zone of an average sized (not biggest, not smallest) Red Dwarf star?
I was thinking about the classic beanpole design for interstellar travel. Wouldn't the Whipple shield need to be at least twice as wide as the ship is long to fully protect it from collisions with ...
A black hole is supposed to suck in everything by nature. Micro black holes are theorized to "fizz out", so for example if one was on Earth it would not grow until Earth was consumed. It would seem...
As per my last two questions asked, I still have a niggling query left regarding a humanoid species in production. To further support their matriarchal theme through evolution, I have decided to ma...
The Emperor (may he live forever) plans to visit the Solar System on a rare royal visit in ten years' time. The Bureau for Interplanetary Tidying have decided that the Asteroid Belt is an eyesore t...
So, I have devoted an unhealthy amount of my time to the dragon question, and a final solution will have to wait... for several thousand years at least. My original plan was to make them at around...
There is a popular belief that the muscles of our body are controlled only by electrical impulses. This is not entirely a lie, but ... From what little I have researched, the nerves send a command ...
Inspired by this question and my comment on one of the answers. If the earth were flung out of the solar system, it would rapidly become far too cold for any unprotected life to survive on the s...
This question here brought up interesting points on what kind of distribution we could expect for the increase in computational power of mechanical computers in a world relying solely on such non-e...
I know of the conceptualized "Sinkers", "Floaters" and "Hunters" that Carl Sagan and Edwin Salpeter of Cornell conceived of - as possible life forms that might inhabit a gas giant. At the time they...
In a story I am writing there is a being with Superman level strength, flight, the ability to produce lasers, and survive in space. He has decided to solve the mineral crisis by finding and grabbin...
So, I'm writing a sci-fi story, which has a setting which involves human colonists crash landing on a massive, icy hellhole. The weather is extreme on the surface, and because of it, wireless commu...
For an elf-like race whose people do not age beyond physical maturity (the accumulated DNA damage associated with aging does not occur), what would prevent overpopulation? This elf-like race is f...
Research shows that some creatures in the animal kingdom manipulate the sex of their child in order to maximize the number of grandchildren. Parents in good condition, based on health, size, domina...
Back home, many large planktivores have ingenious ways to trap food and not water. For sharks like the basking and the megamouth, that is no problem, as they have modified their gills into rakers ...
Imagine an inhabitated planet like ours with a moon of the same projected size in the sky. The moon has visible structures of colors or darker and lighter areas. Every evening when the moon gets ...
