How would FTL travel based on tachyons most likely work?

Not even a little bit plausible. But neither is Star Trek's warp drive, or any other free-form FTL travel in any other setting, so there's not a problem. Just saying that there is faster than light ...

How would time dilate for pioneers travelling to Alpha Centauri Cb?

A little bit more than 4.2 years. For any large time dilation factor, the astronauts spend most of the journey very close to the speed of light in the Earth frame, so you don't need to do a hard ...

How would FTL travel based on tachyons most likely work?

Nope. And here's a bit of why... From any point in time and space there is a Schwarzschild double cone, extending into the past and future at the speed of light. Everything within the cone exists ...

How would FTL travel based on tachyons most likely work?

Since this is SCIENCE-FICTION question, lets play a bit fast and lose here: Your ship travels at FTL speeds by basically abusing Quantum Entanglement: It finds a spot somewhere else in the universe ...

How would FTL travel based on tachyons most likely work?

"Does any of this seem plausible from a theoretical standpoint?" No, it doesn't. Oh, and tachyons do not actually exist, therefore you cannot be "familiar with how they work". They ...

How would time dilate for pioneers travelling to Alpha Centauri Cb?

I am not sure if I follow other answers. Let's ignore time dilation before we hit the desired travel speed for simplicity. At 3g acceleration and deceleration we can reach the speed of light in 4 ...

How would FTL travel based on tachyons most likely work?

Tachyons are imaginary, but that doesn't mean they don't exist. The way they're theorized, they're like quarks, but with a different set of quantum statistics. The creation of the Bose-Einstein ...

How would FTL travel based on tachyons most likely work?

Magic Let us ignore all the initial problems with tachyons being theoretical and the like. There is a very simple problem to solve. You want the spaceship and it's occupants to 'ride along' and go FTL....

How would time dilate for pioneers travelling to Alpha Centauri Cb?

Assuming you have inertial dampeners or functional equivalent, so that we don't need to worry about squishing the squishy humans as in g s's answer, there's an easy ...

How would FTL travel based on tachyons most likely work?

If you want a sort-of-coherent description of tachyon behavior, consider the following: a tachyon is a specially-engineered microscale black hole with an Alcubierre-like warp field built into it. You ...

How would FTL travel based on tachyons most likely work?

If you have tachyons there is one obvious way this is possible: Alcubierre drive. The current theoretical problem with the Alcubierre drive is that to keep contracting space in front and expand it ...

How would FTL travel based on tachyons most likely work?

The basic problem here is that you are asking about something that is forbidden by physics and then asking how would physics deal with it. In science nothing is absolutely written in stone and any ...

How would FTL travel based on tachyons most likely work?

Frame Challenge I suggest that you look at some writers who have used FTL in their stories. I'd start with Ursula LeGuin, Arthur C Clark, Isaac Asimov, even E. E Smith. They all use magic or hand ...
