So I have been looking into FTL for a while now, and have come up with 2 basic rules for my mental understanding of FTL, but it has left me with a big question.
Faster Than Light Travel with require specially crafted materials to facilitate it it (See Worldline numerics applied to custom Casimir geometry generates unanticipated intersection with Alcubierre warp metric)
Faster Than Light Travel will require the energy to accelerate a subluminal bubble of space to superluminal speeds (See Introducing Physical Warp Drives)
Most of the physics here is sadly beyond me and I need to do more research, but it has left me with 3 lingering questions:
If we have already created miniature warp bubbles, then how could we overcome the energy requirement needed to push the bubble past the light barrier?
Would these slightly less theoretical bubbles be able to merge so a line of them have one big bubble?
