How exactly does FTL work in the Frencoverse?
Just curious for the thoughts of everyone else, and wondering if like, all the various factions use the same method to achieve FTL speeds.
Humanity got it's hands on FTL from reverse-engineering the wrecks of Utan ships after the invasion, so everyone's FTL is running on the same base function (that doesn't count tweaks, though).
As for the technical side of things, Auro had a great explanation as to how it functions that I went with.
I'll copy and paste the TG I sent this in.
"In essence, it's a warp drive. But as the speed that the ship travels at increases linearly, the energy requirement to do so increases exponentially. Now, as time passes and more efficient drives are developed, this speed-energy curve gets shallower and shallower. There's also a 'minimum initiation energy' necessary for the drive to actually work, probably roughly equal to the energy required to travel at 1c. As time passes, this energy also gets dramatically lower.
Furthermore, the shape of the warp bubble also matters. Naturally, a large warp bubble needs more energy than a smaller one. But also, the most efficient shape is a perfect sphere. The bubble can only be a spheroid, but the larger the ratio of the spheroid's longest axis to the shortest axis, the less efficient it is. This logically leads to spheroid ships, which are ugly, so I reckon we can make this inefficiency not very large so one can simply disregard it as long as one's ship isn't the shape of a bloody pencil.
It can only be activated when one's not too deep in a gravity well, but this isn't an enormous limitation - for planets the size of Earth and slightly larger, that only means low orbit. There's only a notable difference for enormous bodies, such as stars and black holes.
To prevent the situation of "my FTL bombers warp right to your planet, unleash planet-killers, warp back immideately", essentially stealth in space, a craft can be detected when it's using the warp drive. A craft in FTL flight can also 'see out' of the warp bubble just fine, which is kind of necessary if you want to be able to know when to stop warping anyway. But all it can do is see out and send/receive communications - it can't fire weapons while warping or anything like that.
There is no effective way to engage/destroy/damage something in FTL flight; however, a technology exists which can 'deflect' a craft which is flying past, causing its trajectory to curve away. A beam projector of sorts. This works because the FTL drive can't 'steer' - it can only go forwards. This also has the effect of, if a spacecraft should be warping directly towards it, simply slowing it down. Therefore, if it's fired at a craft which is warping directly away from it, it can accelerate it. This can have interesting implications, I'd imagine.
There are also FTL communications. I haven't thought about this very much, except that it has far, far lower energy requirements than the drive, and therefore can practically be made near-instantaneous over very long distances."
I was thinking that the Nexus/Nexum utilized (tweaked) Albecurrie drives, but since I like all human(species) using the same warp method, I might just go with the reverse-engineered Utan FTL.
What do you think?
