In the movie Interstellar, they go to a planet where time flows by much slower for them while on it because of the increased gravity that planet is experiencing due to the nearby black hole. My que...
It has become accepted knowledge that the planet Earth was birthed via a swirling cloud of dust and gravel clumping into larger and larger pieces of rock. It began 4.54 billion years ago, and 100 ...
Ever since grade school, we have been taught to visualize time in the form of a time-line. This model works particularly well considering the fact that, according to widely accepted scientific theo...
Here are some lists of North American and South American megafauna that went extinct during the Quaternary. In Eurasia, many species of large mammal were domesticated, most particularly the 'big 4...
In a world where man entered North and South America without causing a mass extinction, all of the paleofauna which became extinct ~10,000 BC in the Americas are still around. There are several fam...
The BBC in the UK are currently screening a archaeology series exploring the idea that the Neolithic peoples in the Orkney Isles (North of Scotland) were the cultural capital of the British Isles. ...
Checkpoints have been a staple of video games for decades and are almost as old as video games themselves, but how? These little tiny features have made a huge difference in the way we play games, ...
Each technology, that is evolving, begins with simple piece of programming code that starts with variables of certain data types. It is interesting to note that many calculative and computing techn...
A Kardashev Type III civilisation has need of a long-scale timepiece, and as such has arranged a series of planets around a black hole such that their orbital periods can be used to tell the time i...
In many countries, we number the years based off of proximity to an event in the Christian religion - we are over 2016 years past that date. However, in this scenario, religion has become less main...
Imagine that God has many universes to deal with or just needs a break sometimes. He has a pause control. What plausible mechanism does God use to perform the pause without breaking the laws of ph...
Here on Earth, time standardisation was enabled by the invention of accurate time pieces which allowed us to create a global constant (GMT/Zulu time) and regional offsets. If we travel outside our...
Let's assume I can travel in a space-time on Earth. Every time I jump I get to almost the same place, but in different past time relative to the first jump: it solves the problem of planet rotation...
In the story I'm writing, an ancient civilization once roamed the local group, traveling from galaxy to galaxy with ease. Thousands of millennia after their disappearance, humanity stumbles across ...
I'm writing a Earth history time travel story, and the main character needs to solve puzzles from each time period he visits. I'm going very far back in history and I'm concerned about being able t...
I have a habitable moon orbiting a gas giant, and there is another moon orbiting the planet on a closer orbit. The cultures on the near-side of the further, habitable moon use the transit of the cl...
The story So Bob, the multi-billionaire, is a wealthy person today but in a not so far away future he will lose quite a chunk of his wealth and become just an ordinary millionaire. Future Bob is ...
From 5.96 to 5.33 million years ago, disaster struck the Mediterranean Sea. A tectonic snag turned this... ...into something like this. In this alternate scenario, the sea separating modern ...
Ok, this is take two. Hopefully this is specific enough. I have a link to the original question here. And for those of you eager to see my sources for this, I'll link two videos here from the You...
A person is traveling in a space craft that was designed and built by sufficiently advanced aliens. This space craft left from Earth and is capable of traveling infinitely close to the speed of lig...
Newton who laid out a set of mathematical rules to predict the motion of objects from a falling apple to planets orbiting the Sun, however it was Einstein who described how two masses tend to accel...
Okay so I have a sci-fi world masquerading as a fantasy world where numerous different genetically-engineered humanoids live on nine different ringworlds orbiting an artificial Earth-mass black hol...
How would I future-proof a complex machine or set of machines so that they will still be running 2000-3000 years from now? Is this possible with our current level of engineering and we just don't d...
Major William die in a combat versus aliens. Now he have the capacity to wake up on the same point of time every time he dies. (Movie: Edge of tomorrow) He uses this power to win the war, but he h...
And I mean faaaaar future. Like, twenty thousand years minimum. 13 million years at maximum. Let's say the Earth is doomed and to avoid the impending extinction of the human race, we throw most o...
Okay so in my world, I have two pre-industrial societies that live thousands of miles apart from each other on their ringworld. One lives in a desert climate similar to India or the Middle East whi...
I am a clockmaker: I work with time and can control it on a small scale. One of my powers allow me to return some minutes back in time after having experienced my death, but I remember everything ...
The concept of "age" on Earth is based on the number of revolutions the planet has completed since one's birth. In a setting where interstellar colonies exists, of even in a setting where multiple ...
Asking for what pseudoscience might explain a storytelling need: Given parallel dimensions (worlds), we discover that through a portal device, a person equipped with a special spacesuit-like outfi...
Any ideas how an advanced alien race could speed up time in a specific region of space? I'm working on a storyline in which an alien race uses a time bubble to accelerate time so the construction ...
I'll have a limited space like $1 km^3$ that have (through handwaving) more then three dimensions. But anyone entering it would perceive it as a three dimensional space. A little bit like this vide...
There is a planet that is orbiting around not a single star, but the core of a galaxy. It is independent of the other solar systems in the galaxy, but is affected by the center of mass of the core....
Imagine a human colony with the concept of an Earth day being transported somehow into the deep, deep space between galaxies. As we know, gravity wells affect the relative passage of time. So, in...
A scientist has recently invented a gravity machine. This machine pulls all mass within a certain radius (say 50 feet?) towards it at an adjustable rate. The machine can... create as strong a g...
Is it safe to assume that any two binary planets of 0.5 to 1.5 Earth masses having mass ratios of 1:1 up to 2:1 would always have become tidally locked to one another long before any life could nat...
Assuming that we have a universe with four spatial dimensions plus time, within which atoms exist that can form solids, liquids, gases and plasmas, the compounds that can be formed having physical ...
It's the year 2100, oil reserves are mostly used up. In this hard times Evil Corp has invented time travel and it send back engineers and material to drill for oil in the Creaceous. The question:...
Summary version: So we're talking people living on top of 30 miles of topsoil, fake dino fossils and water on the outer surface on a hollow (but sturdy) unobtanium sphere with a radius about 1 AU....
A village is famous for its flowers and wants to bring in tourism by replacing its timekeeping and basing everything around a flower clock. Schools and shops all agree to set their times by the flo...
I am trying to make a fake metric-time app to prank some friends when we take a trip to Canada soon and would like to know how I could make this work conceptually. I already know that the time is ...
Five million years ago, the warm Miocene gradually descended into the cool Pliocene before dropping into the frigid Pleistocene. Such a change in temperature was so gradual that life went on withou...
I want my actors in outer space but I don't want them roaming around freely. Like, if the actors were in a building, there would be walls, doors, elevators. If they were on a land, there would be ...
This question is closely related to, but more specific, than the question/comment that inspired it: Could a modern times time traveler produce an antibiotic in medieval times?. Imagine a person is...
The Doctor's TARDIS is larger on the inside than on the outside. How can this be achieved? The conventional answer is that The TARDIS is dimensionally transcendental ... the interior exists i...
What sort of time/date system would suit a Dyson Ring, also known as a Ring-World, an artificial habitat megastructure shaped like a circular band, located in the habitable zone encircling a star, ...
In my answer to my own question, Physical laws for a matter-filled universe, I detail the gross physical laws that would shape my four-spatial-dimensional matter filled universe. Given a slowly ex...
In a parallel universe if two objects occupy different positions in space then in the reference frame of each object the other has length contraction and time dilation. If the two objects are very...
I know that in our universe, electromagnetism and gravity decrease with the inverse of the distance squared. Would it be possible though for there to be a force in another universe with three spati...
Okay, so humans are finally transitioning to a space-colonial society. We sent ships out, colonize worlds, etc... We aren't really in the business of sending multigenerational ships. Instead we use...
I would like to have a world on which humans can live unaided -- they can breathe, the climate is workable, they can eat the local vegetation, etc -- but on which a complete day is substantially sh...
