Thats just an artist's rendition of what it MIGHT look like. All of it is purely theoretical
Exactly, they can't develop warp drives due to many factors.
1. Hyperfriction
2. HOW THE HELL DOES ONE WARP?
3. Uses helluva lot of fuel
and etc.
(Looks more like a station than a ship, no landing gear)
1) What the forget is hyper friction
2) It operates by distorting space time into a sort of wave which it then rides
3) Probably yes, but im sure they figured that problem out.
