I do wonder if we will still call them light years when we have faster than light travel? Nice to see some more personnel in game takes in the articles from a players point of view.
Lichtgeschwindigkeit (Vakuum)?
c = 2,99 792 458 · 108 m·s-1?
Und jetzt kann jeder, der die Grundrechenarten kennt, die Entfernung berechnen, die das Licht von einem Punkt zu einem anderen Punkt zurücklegt. Diese wird in Lichtjahren angegeben.
Konstante = Maßeinheit
Ohne Konstanten, keine Mathematik und ohne Mathe wird es eng in der Physik.
The question to the physicist:
Why do you think "light years" is called "light years" even if you can travel faster than light?
Response:
Because in physics you need constants for calculations.
Examples of physical constants:
Atomic mass unit?
Boltzmann constant?
Electric field constant?
Faraday constant?
Gravitational constant?
Hubble constant?
Rydberg constant (m → ∞) ?
And.
Speed of light (vacuum)?
c = 2,99 792 458 - 108 m-s-1?
And now anyone who knows basic arithmetic can calculate the distance light travels from one point to another. This is given in light years.
Constant = unit of measurement
Without constants, no math, and without math, physics gets tight.
It's like Schrödinger's cat....

Welcome to the forums!
Great answer, my question was off key; I was thinking along the lines that we would change to a warp year (even month or days) unit when measuring the distance between stars. But light would still need it's constant and we don't say "Its "travel time" from London to New York" as that can chnage, we talk in terms of miles and kilometers which are "constants" (not by physics, by international agreement).
For this, a locomotion with a multiple of the speed of light is necessary, but this is impossible according to the statements of the theory of relativity - the today generally accepted and many times experimentally confirmed state of science. Because: To reach the speed of light the moved mass becomes formally infinite. Thus infinitely much energy is needed to travel so fast. There even a hypothetical owner of a "death star" becomes envious. Almost like in Star Trek, where the energy of a sun would have to be applied according to calculations of witty physicists - for doe famous cup of Earl Grey. That's probably why the developers of Elite Dangerous didn't include Witchspace as a unit of measurement in the game. However, the developers have included a total of 400 billion star systems in Elite, and 160,000 of these systems correspond to real models. So, no - sorry, I can only speculate.
Have a nice weekend!

Warum nennt man "Lichtjahre" wohl "Lichtjahre", auch wenn man schneller als Licht reisen kann?
Antwort:
Weil man in der Physik Konstanten für die Berechnung benötigt.
Beispiele für physikalische Konstanten:
Atomare Masseneinheit?
Boltzmannkonstante?
Elektrische Feldkonstante?
Faraday Konstante?
Gravitationskonstante?
Hubble-Konstante?
Rydberg-Konstante (m → ∞) ?
Und...
