# Superluminal Travel Time Formula (STTF)

t = Roughly the time it takes to get to the star in seconds, if you don’t multiply the result by 31,540,000, it will be measured in years

d = The distance from you and the star in light years

v = The multiplied speed in c your FTL drive can go, it doesn’t actually calculate the speed of light in meters per second (299,792,458 m/s), it just calculates it as a number, like 1c, 2c, 5c, and so on.

t = d ÷ v * 31,540,000

Remember that going at or faster than the speed of light will be instantaneous when you arrive at the star, unless you are a distant observer

Here is a calculator for it

• i actually just realized that i created the already existing formula for travel time, just using the speed of light 😂😂😂

sub-light travel is rocket science, near lightspeed travel is rocket science with more energy

So, basically t = d/v as credited to Galileo Galilei and many others before his time way back when? Not trying to burst your bubble, but I just got to say it. Anyways, you can take this a step forward to make it also useful for sub-light travel. Add the length of burn time for the acceleration and deceleration burns using a variation from Tsiolkovsky's classical rocket equation. This equation is t = ( (M_initial * Exhaust Velocity) / Thrust ) * (1 - e ^ ( - Velocity of Burn / Exhaust Velocity ) ).

@FriendlyFin yeah I thought it was kinda weird to use the speed of light in a time formula

no no we don’t use the speed of light anymore in this formula

@FriendlyFin oh okay I see what you mean like you use the v relative to the c

because 1 * 26.02004054987223 = 26.02004054987223

and from my experience of complex math you must involve multiplication and division for variables

and subtracting 10 (which is how fast the alcubierre drive can go in c) from 299,792,458 (c in m/s) won’t make any significant changes, it is now 299,792,448. you’re gonna have to subtract it from 10^a lot to have an impact

why would you multiply the speed of light by the potential max ftl speed? It would make more sense to subtract the max ftl speed from the speed light
edit: nvm I wasn't looking close enough
