I'm trying to calculate the solar declination at the solstices, solar altitude at solar noon, and hour angles at sunrise and sunset to build a standing stone calendar at latitude 53.8 degrees South...
[Critter's descriptions] (D1) appearance closely resembles a cat (D2) no bigger than a dog (D3) toothless (D4) strange claws to climb any surfaces (D5) powerful hind legs can sprint like a cheeta...
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...
Some of what I read in How could a 4D organism influence events in our world made me think in a different direction about a question I asked before. I'm trying to create a large sphere shaped fiel...
Imagine a civilization developing on Planet X that is orbiting a black hole (or a similar gravitationally massive object). Given the time dilation near such a massive object, do the inhabitants of ...
In this question, I asked about a matter-filled 4-spatial-dimensional universe, with a gross structure defined by my own answer to that question. Then, in this question, I asked about what the per...
A wormhole usually helps us to create a shortcut to a distant object through a higher dimensional space. Can the time factor in that higher dimensional space differ from our three-dimensional spac...
I am working on a story and came up with a doubt regarding an explanation given for time travel using wormholes as portals. The below given is taken from Wikipedia link: https://en.m.wikipedia.org...
I have a character who ends up jumping backwards in time by 24 hours. Essentially nothing else changes, but the character has their jPhone in their pocket at the time of the jump. How functional sh...
For us earthlings, the concept of "year" came from the observation that the Sun reaches a minimum and a maximum span in the rise-set path in the sky. On a planet experiencing extreme perihelion p...
I am working with a story. I wish to make my story somewhat logical by adding some science and thereby not making it to appear fantasy. This story is on a fictional planet far away from Earth. Let...
I wish to clarify my doubts regarding time dilation Is it possible for a planet to be habitable like Edmund's planet from interstellar, which has somewhat similar gravitational force as Earth (9....
Faster than light travel is a really cool thing to have in sci-fi settings. It allows humans, in relatable time scales, to travel the galaxy and see a variety of worlds. It allows for conflicts spa...
For a SciFi project I work on I have a space-station orbiting earth that uses an 8 hour 3 shift system for its staff. Each shift is assigned to one-third of the countries and organizations on earth...
I was reading Flatland, and the thought occurred to me that interaction between an n-dimensional being and a n+1+-dimensional being may not only be difficult but dangerous, that Flatland contains e...
You are native to a planet that falls between two suns, thus ensuring eternal sunshine. How would we be able to tell the time? Do you formulate some kind of system based on which sun is in the sky...
This is my first post, I apologize in advance if my English is not accurate, it is not my first language. My question is: in a world where very advanced civilizations have achieved intergalactic t...
There seems to be a connection between orbital revolution (one year) and distance from the star the body orbits. For example, Earth orbits the sun at a distance of 93 million miles and completes o...
I find time dilation confusing so I'm not sure if it is a relevant factor. Lets say you have a spaceship. There's no such thing as faster than light travel, but you do have inertial dampener techn...
We have these "magical" items everywhere in fiction; from the classic rabbit coming out of a hat illusion, to the TARDIS from Doctor Who, to Newest Magical Beast Newt Scamander Briefcase. These ite...
What would be able to explain a visor like device that can see the past or future? I'm trying to make it as little as clarketech as possible. Any ideas?
In my universe a 4th SPACIAL dimension exists around our 3 dimensions. I'm playing with ideas for a society that has access to a 4th spacial dimension and am currently thinking of what they would b...
Note: I'm talking about a fourth spatial dimension. As far as I can tell, a 2 dimensional creature has one possible digestive system structure; have a cavity inside its body connected to the outsi...
I'm working on a science fiction story involving starships travelling about 95% of the speed of light. I wanted to have a reason for the starships to need to shield themselves against time dilation...
I was imagining a scenario where an 21st century engineer accidentally finds himself transported through time to early Renaissance Europe. Realizing that no help or rescue is on the way, he decides...
In my world there is a neolithic civilization of people who inhabit earthen trenches. The people first soften the earth with ... fluids ... and dig out 6 - 12 foot deep trench systems that extend o...
Suppose we have a Branching Timeline paradigm, in which time travel into the past creates a new timeline. Is it fair to assume that any probabalistic events which might occur might be very differe...
In novels (SF and FF) that hint at being earlier in Earth's history, such as Lord of the Rings and The Wheel of Time, in which period would such a story need to take place to plausibly and realisti...
I saw this old closed question on Physics.SE and thought it would be perfect for here. The original author is long gone, so I thought I'll just have to post it myself. We can consider factors of p...
So I'm not sure this is possible but I was hoping someone might be able to figure out a way for it to work. My planet is smaller than earth. I'd say about 75% the size. However for plot reasons, I...
So it's plausible that any planetary civilizations (alien or human) may have landfills. It is also natural to think that many planetary civilizations would die out, or migrate away from a planet. S...
In 1890's H.G. Wells famously takes a "science fiction" approach to time travel by building a machine that can move freely through time as a dimension. It was made of clockwork "” mechanical gears...
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...
From 359 to 298 million years ago, the "Carboniferous Coal Swamps" dominated the continents. It was the Carboniferous coal itself that sparked one of the greatest watersheds in human history--th...
Because of an error in the interpretation of the Mayan calendar I just discovered, I know now that Earth will be destroyed on March 13, 2021 at 11 o'clock in the morning, time zone of Palenque. I ...
All known life forms have life cycles that are not time symmetric as they look different when time is reversed. I was wondering if there could be a life form that would have a life cycle that wou...
Okay, so I have a sci-fi setting in which there is a form of FTL travel. Imagine the universe(all three/four dimensions of it) was stretched out onto the surface of a sphere. Now assume that ther...
This seemed too scifi or hypothetical for physics, so here goes. Suppose a manipulated quark with 0 mass could travel faster than the speed of light. It's known that the faster you go, the slower...
I just got shoved through a stargate onto a planet I don't know. I was told the gate would open again in exactly one Earth year. I wasn't carrying anything; I don't even have my watch. How do I k...
Our perception of time is steeped in the rhythms of our world, and blended with the most ancient of superstitions, decrees and mathematical conveniences. Thus we have days that track our world's ro...
Let's say we have a wild rabbit that can see a few minutes into the future. Being a non-sentient animal, it barely registers these abilities, and largely uses it to find food, avoid predators, save...
I am trying to understand the physics of an interstellar race. Say two ships are racing past a black hole as if it were a corner on a race track. One of the ships takes a hard line and comes very ...
We know the depressing fate of John Doe who woke up one day in the Middle Ages, to quickly die or spend his life in a monastery. His more lucky friend Mark had a vision before being transported a...
When I was younger I learned about time dilation and since my story was (and is) set post-planet I thought many hours about how to handle it. I came to the conclusion that I could just drop it and ...
So, here's the setup. Spaceship emergency lands on a habitable planet in the middle of a desert. Being a desert with decent wind movement, the ship quickly ends up being buried under the sand. A f...
Imagine a world with time travel, got it? Good. Now imagine that time has multiple dimensions. Time has its OWN dimension of time, along which it can evolve. This is called hypertime, or "w" (As i...
Judy likes coffee. Right now he is standing in the middle of the urban park sipping it. Unbeknownst to him a local phenomena occurs somewhat near: space itself bends where a lovely group of lilies...
I am working on a story which is based on space time hacking and moderation. While researching I found that a wormhole is simply a Folded time-space-as shown in demonstration below (Image credits: ...
I've got a cave civilisation who have never seen the Sun, and don't have much of a concept of time. I was inspired by a Reddit post from someone with a similar situation, and like me, the OP was wo...
If a spaceship left earth traveling at near or at light speeds (that being possible in this situation) would they not when coming back to earth, arrive many years in the future due to Einstein's th...
