Re: Relative Velocity Time Dilation:
Pioneers have travelled 4.2 light years to Alpha Centauri Cb in 9 months. Handwavium tech can transport mass in this timeframe. Upon their arrival to Cb, they are ...

How would FTL travel based on tachyons most likely work?
So, I am trying to design an FTL system for my sci-fi setting. I find the concept of tachyons to be intriguing, and want to incorporate it into the system, but I'm not that familiar with how they work....

How would I pull off FTL travel in a universe where inter-universal travel is also widely used?
I'm trying to implement proper FTL travel in my story. I have already looked at the Alcubierre Drive, but every implementation of said drive that I've seen is too outwardly obvious for my taste. ...

Speed of light in higher-dimensional space [closed]
In science fiction, one of the widely used tricks for achieving faster-than-light motion is traveling through "hyperspace". By that I mean, entering a space with more than 3 spatial ...

Can an Alcubierre drive be built by starlifting?
I am setting up a very futuristic world for a sci-fi story, where having FTL tech would be very practical. For a bit of context, here is what I am imagining:
It is a type 3.2 - 3.3 civilisation, where ...

Is it reasonable for the development of faster-than-light travel to significantly slow the development of machine learning technology? [closed]
One of the settings I'm in the very early stages of working on is based on the idea that, if humans had somehow developed faster-than-light travel in the mid 2000s, the development of machine learning ...

What could be used to explain the visual effect of the ‘Blackout Flare’ phenomena described?
As stated on a work-in-progress document for the phenomena I’m referring to as “Blackout Flares”:
A Blackout Flare is a short-lived, instantaneous warping of shadows produced by an object moving ...

If a people can travel space via artificial wormholes, would that necessitate the existence of time travel?
The primary mechanism of “faster than light” travel in my story is via artificially formed wormholes that can be created to transport a craft to a reasonably precise location. Would the existence of ...

Where can a non-clarkean civilisation find an FTL Space-drive?
So, this is the deal. In this scenario, humans are unable to create an interstellar civilisation. They have tried colonising exoplanets the slow way, at about a quarter of the speed of light, but this ...

Would a living being moving at 99% the speed of light see time stop, or would it see time move faster?
Let's say I want to write about a living thing that can naturally go to 99% the speed of light in just one second of acceleration.
I would like to write what this being would experience at such speed ...

How do we create an interstellar communications system?
In my science fiction project, humans have settled in a new Galaxy, known as the Novan Cloud. In order to communicate information to other alien races humans require, alongside superluminal travel, (a ...

What would the launch and explosion of FTL-missiles look like?
In Effects of being hit by an object going at FTL speeds, the effects of a spear going at FTL speeds are debated in detail.
For my setting, humanity's last hope of stalling an alien invasion comes ...

A device to negate time dilation believability [closed]
In this setting spacecraft are able to approach the speed of light and are equipped with a device to negate the time dilation, this allows things to go horribly wrong if this device fails plot wise.

How would the laws of physics need to be adjusted if there really were a preferred frame of reference for FTL?
I am considering how to implement faster-than-light (FTL) travel in a sci-fi setting without the attendant problems with causality. One of the ways I've been thinking about for this is establishing a ...
