# Length contraction at FTL? Are slower FTL speeds “faster”?

## Recommended Posts

I’m not a physicist but let’s say hypothetically ;we have the Millennium Falcon. It’s FTL hyperdrive can go Class 0.5 past lightspeed. Then we have an X-wing which has a Class 1 past lightspeed drive. This is all from the lore. MF is 0.5 and X Wing is 1 but MF is faster. Anyway even though the Class 1 is “faster”; is it due to length contraction at FTL that’s make the lower grade drive faster or am I hopelessly off base?

well considering that star wars lore legends and main cannon both say that FTL is achieved through exploiting another universe/plain of reality getting around all if not most of the issues that come about because of light-speed travel let alone FTL

but i'm assuming your asking how does this nonsense works in a mechanical way and in that case X-wing has a class 1, the millennium falcon has class 2 the difference between the two is the multiplier applied to the travel time where the class is the multiplier e.g. 1 days hyperspace travel can be covered in 1 day by the X-wing while the millennium falcon takes 2 days. and yes a class one can travel slower to allow for a coordinated assault like the battle of the second death star

The Millennium Falcon has a Class .5 hyperdrive which means that it takes 1/2 the time of the general measure. A Class 1 hyperdrive goes at the speed of the general measure. A Class 15 hyperdrive takes 15 times as long to reach a given destination as the general measure.

@P-47 Thunderbolt is correct here. The rating for a hyperdrive is a multiplier. You multiply the base time a trip normally takes by this amount in order to get the actual travel time.

That's ok, the people that came up with the FTL stuff aren't either.

But yeah, as other's said above, the number associated with the FTL drive, is the multiplier used to determine travel time.  So the smaller the number, the better.  The Falcon is super fast compared to other ships, because it's got a 0.5 multiplier.  So any travel time you plug into the Falcon's drive calculations, will be significantly shorter duration than a x1 or higher.

A good point here (silly pseudoscience incoming) is that hyperspace isn't FTL. I mean it allows you to move obscenely faster than the speed of light, but because of how it works, you're actually cheating physics to do it.

The whole deal with hyperspace is that instead of actually going x times the speed of light, you're instead bumping over into another dimension where the laws of physics don't apply in the same way, both allowing FTL travel and bypassing things like time dilation, energy requirements, and so on.

Narrative-wise it's a cheat that allows you to cover extreme distances quickly with a simple hand-wave, while also applying just enough bogus science to explain away real science.

Almost like it was cooked up by a bunch of art/film students to tell a big story, and not people who study high-level quantum mechanics and gravitational theory and whatnot.  Imagine that.

Yeah. Ghostofaman is absolutely right. It’s one of the higher 11 dimensione.
