I've seen some cool art and scenes from the Cowboy Bebop which had trade lanes made up of what looks like large rings that accelerate and deccelerate a ship. I wanted to replicate a system like th...
Let us say there is an adult male, adult female, a boy, and a girl. They experience time-travel. As a psychologist, what would you examine before and after the travel to ensure that psychologicall...
Looking into fleshing out my world story. One of the things I had in mind was an infrequent but consistent shipment of supplies to a planet from Earth. For simplicities sake, we'll use 10 as the nu...
Setting: Modern day Earth, no special technology advancements. Situation: On day, in a relatively populated American city (the specific city is unimportant...the purpose of this point is that it's...
This question is inspired by Could a species develop the tech necessary to land on their own moon without comprehending light? Consider following scenario: a civilization of alien tricksters abduc...
Inspired by comments to JBH's answer to The worlds between, the consequences of instantaneous FTL. The Premise A technology for instantaneous travel exists, making it possible to travel to any po...
What additional difficulties might the inhabitants of a gas giant moon face when attempting to launch spacecraft beyond their moon's orbit, especially beyond the planetary system? I presume that th...
IF they were real, would wormholes work in the way that they do in sci-fi (for all intents and purposes "teleportation", travel without movement, FTL, immediately "appearing" at the other location)...
What properties of a species of plant would make it the ideal choice for taking it on a year-long trip through space as both an oxygen source and food source? We should assume that the amount of ...
Is it possible to calculate/estimate the size of a star's heliosphere? If so, how? I am working on a semi-near future, sci-fi novel. As part of the technology base, humans are able to travel betwe...
Executive Summary Thank you for considering Chronograph Talent Consulting for your talent acquisition needs. We select the best talent from all previous periods of human history and make them ava...
Suppose I have a time-traveling DeLorean (of all things), and I've used it to travel back to 1955. But then I ran out of juice. Fortunately, I just happen to know that a certain clock tower will be...
I've been wracking my brain about a world I'm writing in, how to make some group of regular people able to survive in space for extended periods with or without a suit. I can reduce the amount of t...
Assuming we never break Newton's third law, in the near future thousands of chemical/nuclear/electric powered spaceships will be flying through our solar system expelling reaction mass. Since a g...
In Charles L Harness's 'The Paradox Men', a spaceship crashes on earth several years before it launches, having circumnavigated the universe faster than the speed of light. It is a good read, but ...
The idea of "Flat Space", an area of space-time with minimal, preferably zero, gravitational curvature, is an important concept in many Sci-fi universes, often those with "jump-drive" based FTL tra...
Imagine I have a device that can stop time for the person who holds it (similar to Bernard's Watch). This device works in a very specific way - it creates a bubble around the user (just large enoug...
This question would be best answered for the time period of our first colonized planet, which will most likely be Mars. With the thinner atmosphere, weaker gravity, low oxygen, and the bodily damag...
It's the height of humanity's space-colonization golden age when casual interplanetary travel has become possible and humans have either colonized or established large space stations around nearly ...
I want to be able to have interplanetary travel very cheap and fast, within minutes. Seeing as planets are light minutes away from each other, I suppose even for fast interplanetary travel the tech...
When flying a big spacecraft, one needs to keep several things in mind when designing the "user interface" used to control the spacecraft's flight path, or ultimately, the output of the thrusters/e...
Assume a world with no multiverse theory, just a single unbroken timeline. If you were to go back in time to the town your parents lived in on day of your conception, the air displacement due to yo...
First, yes I was inspired by this question: "How do you check if a room behind a door aboard a spaceship has an atmosphere/pressure?" I wanted to take the scenario further, instead of asking how t...
Consider a near-future situation where humans have begun to explore the solar system, most groups are still working to start a profitable mining operation and only a few ships have gone beyond Jupi...
Prelude Prelude TLDR; A fleet of ships is passing through our galaxy, stopping off at particular stars and causing small dips in the light from stars. This is related to a couple of other questio...
In my world, humanity reaches their new home among the stars by way of a portal that pops into the solar system one day. This portal instantaneously transports those who enter to a place that is lo...
In the near future, say about 50 years, the most powerful governments are starting to compete for control of interstellar resources. The first step is to send a probe or probes to a neighbouring st...
The title says it all. How would one go about creating a planet with aliens that have medieval grade technology (windmills and carts and stuff.) No high level technology. However, I want the aliens...
I am writing a hard science fiction story and I want to avoid violating known physics, while still enabling some of the classic mainstays of science fiction under the auspice of sufficiently advanc...
While once living in Texas, my family and I had the privilege of watching a shuttle re-entry. It was breath-taking. I kid you not, it was like watching the finger of god drawing a line of fire th...
I've seen many sci-fi scenes that feature a ship underway on a deep space journey. As the ship passes the vantage point we can see engines burning during sub-FTL speeds (The Expanse most recently)....
I'm trying to figure out a concept for some sort of super-advanced space propulsion system that works by bending spacetime. As I understand it, planets' orbits are actually straight paths, but the...
Let's imagine that people, if they'd want could freely leave Earth to pursue their own destiny on other planets etc. How far could we get assuming following: Assumption No. 1: It's trivial to get ...
Suppose you had a device with the ability to temporarily give your ship tachyonic properties. Would this allow for FTL? How would it affect warfare in a sci fi universe? The reason I am asking thi...
After a long forgotten apocalypse, humanity struggled to rebuild itself, so of course, no one has been in outer space for over half a Millenia. In the early days after the cataclysm, newly formed f...
Can two objects solar powered, equal in weight, traveling on the same orbital path in the opposite directions propel each other to intersect on the opposite side of the Earth in alignment to propel...
Suppose NASA, SpaceX or any other aerospace company has managed to build a technology that allows them to fire a rocket to the moon, from "space". Basically, they have created a huge weather balloo...
So I'm working on a story that at its groundwork has a lot of sciency things, and then has a lot of unsciency things attached to it. The story has an FTL drive which is the good old "fold space, pu...
I'm writing a game script at the moment that involves the protagonist exploring various planets in several solar systems. The character starts the game with nothing to their name, but I want them t...
Assume that you are in an alien star system. Your ship is currently being hit by a phenomenon called solar overflow, which messes up your electronics and can kill you without good shielding. It is ...
[![enter image description here][5]][5] Model Lightcraft under laser power While sadly the funding for this research has not been forthcoming, there have been proof of principle flights and ope...
When in space, the amount of force required to move goes down drastically, due to the virtual lack of drag. In this environment, would be feasible for engines in space (more specifically belonging ...
Let's take a world that is based heavily on Elon Musk's specific ideas of Mars colonization, to whit: Launch technology from Earth evolves to be to <$100/lb cost to launch ratio, due to reusab...
In my universe, there exist molecular level machines that can behave as a single entity. The humans use them for many purposes, including faster than light travel. The concept is as it follows: T...
Please reality check my place from which one could watch time outside move faster... A space station constantly moving at near light speed. The space station is created by a race with superior te...
Ok I have a moon, or cored out moon, that is a generation ship. I really do: I built it by mining out one of the rock/ice moons around my solar systems gas giants (not earth's solar system). Its...
I had in mind a sci-fi setting where humans have begun terraforming nearby planets without the benefit of faster-than-light travel. For example, Wikipedia lists a handful of terrestrial planets wit...
Sci-fi setting where cargo is being shipped to colony worlds. If a spaceship has to land and take off again, that costs a lot of money, so that mode of transport is reserved for people and urgent, ...
In the universe there are several worlds where energy harvesting is feasible without pesky wild life habitat preservers standing on your patch'o land bare breasted. So earth has set out to harves...
It's now the late 23rd century and there are now hundreds of space stations, orbiting approximately at the height of the (now deceased) ISS, give or take a few kilometers. Lately, the International...
