I was wondering if there is a scientific way to explain how my characters are capable of extreme levels of strength when engaging in combat. My characters are biological but have implants that all...
Please note: I am asking about planet orbiting a star, not a moon orbiting a planet. So I've been trying to get this planet down for a long while now but there are still so many pieces of the puzz...
so i want to know What organs or modifications are need for a biological creature to develop lethal force as a pooping machine gun. something like how skunk spray their stinky odor as defense mec...
So in my world there's a creature as big as a common rodent or as big as a rabbit in size. They live in packs, usually burrowed, but occasionally come to surface to get food. The alpha male is task...
Ecosystems like the african savanna have lots of megafauna which to some extent compete with each other for the same prey/vegetation, but still coexist just fine. So how do I construct similarly d...
You are 70 years old but you look 50, this because you have always maintained good health, mentally and physically. After experimenting with various clones before, you decide it's time for you to ...
So in my setting there is a small and exclusive group of people that have access to devices that work like computers (but which are not the same as computers. They do not use semiconductors and ele...
While I'm working on the Magical Artillery, let's look at another common spell. Mage Light is a very handy invention. When cast, the spell creates an orb, 13 cm in diameter. The orb radiates whi...
Imagine your spaceship encountered a gravitational anomaly and discovered that you are lost in space, your computer tells you that you are still inside the Milky Way galaxy but it cannot find the S...
Pegasuses in most works of media are often depicted as hexapods with four legs and two wings: The only problem is (from what I understand) no vertebrates on earth are hexapods, so I've decided ...
In modern day society, few or many people have been fascinated with integrating robotic parts to their bodies. But sometimes that idea is taken to the next step, in which people want to have their ...
So, in the S.S Portland (The main setting of my story) there is a variety of rooms. A lounge, a lab, etc. so, i was thinking that at some point, the lounge would be changed out for a 0-g pool. A ba...
Don't you just hate when Euron injures your pet dragons and perforates your fleet with a ballista? Don't worry, all you need is a shipful of Wildfire and a very long fuse (or Mehdi Sadaghdar with ...
Atlantis is real. It's just that there's more than one of them, and none of them are actually called "Atlantis". Instead, they consist from the Kerguelen Plateau in the Indian Ocean to Zealandia,...
A major plot point for my story is the Protagonist stumbling upon a planet that was purposely hidden from the rest of the galaxy (at the edge of the galaxy) as it's being used by high level governm...
Consider a planet with Earth like gravity but an atmosphere that is 10x what Earth has at sea level (atmospheric composition is equivalent to Earth). If the vegetation is similar to Earth's, would ...
We have a variety of ways of describing our location here on Earth. We can refer to a nearby landmark (eg "by the City Hall"), we can describe our location relative to an area (eg "in the South of...
In my setting Dragons evolved on a n isolated continent far from where man evolved. But in the past thousand years dragons have been introduced to the human inhabited continent, which is filled wit...
When designing a flying car intended for congested city routes with slow traffic, should turn signals indicate all possible directions. In most sci-fi, I've seen designs that have no turn-signals o...
In my question: Sustainability of Regular Global Wildfires Due to Oxygen Rich Atmosphere An answer was proposed for a kind of "Boom Bust Cycle". The atmosphere has little CO2 but a lot of O2. W...
I'm making a series where a multi-purpose frigate travels to Jupiter in order to help in the Mars versus Jupiter war. However, I don't know what the colonies would look like. Maybe floating wit...
In a scenario in which all heavenly bodies are flat including earth. How to bring the effect of day and night effect like now i.e when day in japan and night in USA . Considering nobody can live b...
The species I have created looks eerily humanlike, practically indistinguishable from human except for a reptile-like tail and an exposed brain. The top portion of the skull is replaced with a gla...
Imagine a cuboid planet with a thick atmosphere orbiting a star similar to our Sun. The inhabitants are as intelligent as humans and recently discovered the universal laws of gravitation and motion...
Eusociality, is the most sophisticated level of organization of sociality, is defined by the following characteristics: cooperative brood care, overlapping generations within a colony of adults, a...
Given that you can travel back in time and have a baby there, or alternatively, send your baby back in time, would it be possible that this baby one day becomes your own mother (gives birth to you)...
Good day everyone. I've recently finally gotten around to writing a sci fi novel but need help on some of the science of a few concepts I would like to incorporate in the novel. I'll start with ...
The universe is dying because it has exhausted nearly all of its resources. Humans became the last species in the universe because of their resilience and sheer willpower. And yet, humanity still...
Shamelessly inspired by this question, where a race was capable of counting only 0, 1 and "˜many', I have designed a yet more extreme race!! The Continuuoids are a pretty complex race. They can so...
Earth rocks are largely silicates, combinations of silicon, oxygen, and various other trace elements. What would a planets geography look like if the crust was primarily composed of ceramics like...
Reptile reproduction, it turns out, is more flexible than our own. Whiptails, a girls-only species, can lay unfertilized eggs without the need for a male. And Komodo dragons have recently been di...
I am doing some hard sci-fi worldbuilding and really want to get as much correct as I can, but the effects of high sub-light speed travel on the travellers is doing my head in. I've pored literally...
In a distant galaxy, there is a young, yellow-white star. Orbiting this star is a gas giant comprised almost entirely of oxygen-nitrogen, and water. In its core, there is a relatively large nickel-...
My species lives on a world that is filled with very few storms, lush environments, and naturally forming metallic monoliths. The species are like humans, but one thing that sets them apart from hu...
Imagine a species of humanoid beings living on an Earth-like planet somewhere in the universe; they have developed complex spoken and written languages and they can study their own anatomy and the ...
In terms of scientific and engineering challenges, which one is closer to fruition? Specifically I am looking for the feasibility of using one of these systems for space-only travel between the orb...
Mariam Nabatanzi Babirye is a woman in Uganda who has had 44 children in her life due to her bearing many children at one time. This unusual situation is because of a rare genetic abnormality that ...
So I remember reading a long time ago about how a theoretical "wave" could exist, as the laws of physics suddenly changed in one place and then this rippled across the universe, basically at the sp...
(I'm new here, so if I'm doing something wrong please let me know) I have an idea for a world where most fauna (and potentially flora) have floating, disembodied limbs that hover in place. Think R...
Imagine a race of humanoid alien living somewhere in the universe evolves weird sensory organ which can only picks up frequency of light ranging from 800MHz up to 2.5GHz which is in the microwave s...
This is another question that seeks to provide assistance in the design of ''Eosi Humans'' an alternate human species which makes up the population of my fantasy world ''Diggoran'' ( Pronounced Die...
Since the 1800s, the levels of testosterone has been steadily rising in males across the world. The increase in male testosterone has increased strength, speed, height, energy, and aggression. The ...
