I wonder if these guys know about the conservation of momentum! In order to accelerate a mass in space, you have to expel mass. Nano stuff isn't going to do it.
The ships are particle accelerators. So they are expelling mass at nearly lightspeed. There’s your propulsion, and that’s why the ship has to be kept tiny and light.
