Stars are born through the fusion of light atoms and the star's nucleus. So let's say that as a star is being born, the nucleus split and creates two stars. Could this even happen? If so, would the...
Is it the case that if I was to develop an alien world that the most likely outcome would be that the animal in the middle of the food chain is going to be the one that is most likely to develop in...
Humanity has been exposed to prolonged nuclear radiation for thousands of years. In the past, hundreds of nuclear bombs dropped; then nuclear warfare ceased for thousands of years. Assume that hum...
Was wondering if anyone with physics knowledge could tell me something about desert worlds. If the surface of a planet was mostly a fine sandy material (e.g. Sand) then could tidal forces cause th...
Let's suppose a solar system: A main-sequence star similar to the Sun. G2V or so. A Hot/Warm Jupiter HJ with a semi-major axis somewhere from 0.5 AU to 0.0001 AU. An Earth-like planet EL with a s...
What materials would be significantly better than currently commonly used radioactive materials (Uranium/Plutonium) for energy generation? I am looking for some material which could've been brough...
The capital of the society my story revolves around is built on top of a cliff, similar to the White Cliffs of Dover (pictured below for reference). For story reasons, they settled in this location...
Imagine a terrestrial creature with a sail on its back, like a Spinosaurus or Dimetrodon. Would it be possible to use this sail as a lung for oxygen exchange with the air?
Is it possible to create a scenario where nuclear power is a practical option for nomads living like in Mongolia? There's two possible applications of nuclear power. One is to just use it as a hea...
In Nemesis Games, the 5th book of The Expanse series by (pseudonym) James S. A. Corey, a disenfranchised group seeks to disrupt the solar system by "dropping rocks" on Earth (pushing or otherw...
All right, so I have a game that I already made, the concept is that there are "planets" that do not move and ships that can stand still without being sucked in to the gravity of the planets. I ne...
I am in the midst of writing a book wherein one of my characters (Let's call her X) can affect spacetime, mostly by causing time to dilate. My character is earthbound and a shadow organization di...
In a setting with (mostly) near future technology what material would a top end naval spaceships hull be made out of? The hull must follow the following requirements: Able to withstand the strai...
What orbital parameters could I give seven Mars/Earth sized planets so they have stable orbits around a G-type star like The Sun, they need to fit between 0.5 AU and 1.7 AU.
A great way to introduce advanced technology to a story is to have it be of extraterrestrial origin. E.g. have a spaceship crash on earth, or, like I was planning to, put a derelict spaceport on th...
Suppose you have a race of early people similar to humans, except that they have fish eyes to help with peripheral vision. Would this adversely affect their spacial reasoning skills? It seems that ...
So, with all the recent discoveries and almost certainly true theories that a few of Jupiter and Saturn's moons could have a subsurface ocean, notably Enceladus and Titan, would an ~10 meter long s...
First of all, this website is a dream come true. I'm a total sucker for this stuff. Secondly, I love astronomy and worldbuilding, and lately, I've been thinking of a hypothetical situation, and wa...
Imagine a large butterfly- or moth-like creature, with a wingspan of about one meter (it's moth-like, not actually related to Earth insects). It lives its entire life high in the open sky, never to...
Disclaimer: This is not a duplicate of this question. This question deals with a specifically non-marine snake. My fantasy story requires a giant snake. The easiest way to create one (as far as f...
I'm considering the mechanics of a "shock and awe" scene in my novel which could see an old dam being brought down. The era is equivalent to that of the middle Roman empire, so introducing explosiv...
My question is as the title put it. I would like to know how large and thick of a wall we could currently construct. Given we have no limitations in money or materials. Bonus if it's actually sturd...
In this universe, the planet Paveiha has a mountain range that completely surrounds a region in a semi square/rectangle(ish) shape. Inside the borders of this vast mountain range is a verdant land ...
I'm writing a short story about space faring race of people. I want to emphasize how technology has allowed a casual approach to space, making it seem like only a minor inconvenience or hazard. O...
Following in the vein of super-villains with problems... I am an anonymous villain (the best in my world), and have recently bought some new land and am in process of building on it with the inten...
