So ships banking in space has been bothering me for a while. This has likely been hashed before but I’ve been unable to find a reasonable SiFi explanation.
From what I have seen, ships in EVE slow down due to the influence of the warp core “dragging” on space. I’d like to propose a further explanation as to why ships bank and otherwise act like they are moving like aircraft. With aircraft the whole point of banking is to produce horizontal lift. In space there isn’t any “lift” so banking makes zero sense. Maybe there can be something else.
I think it has already been described that the warpcore manipulates space time around the ship causing “drag” which causes the ship to slow to a stop without thrust. Since acceleration is per second second if local space time were distorted such that time in the direction opposite of V was “faster” then we would observe a force in opposition to our V. Existing lore describes the core as a device which basically digs a hole into the quantum foam to essentially create a space where the speed of light / time is faster and we drag that through space. The problem here is relativity. Since there is no privileged reference frame what does stop mean? If we mean it to be in reference to the universe then we have a problem. If we take it to mean the boundary energy of the bubble matches the local curvature then it would be in relation to gravity IE planets, stars, space stations if sufficiently close. This would be much more acceptable as it does not imply there is a universal STOP velocity. I think this explanation could work. When the ship is moving in relation to the local space time the core would observe compression along that vector. Acceleration would be this squared so the harder you accelerate vs the diameter of the field would result in larger forces.
Anyway from that, lets address banking. Since the core can manipulate the field if we induce a distortion such that time is off axis from V we would essentially curve space such that we could curve the line projecting along V to be our desired turn. Thus thrust in one direction would result in off axis acceleration. This would be limited to the strength of the core vs the thrust of the drive. However now the core is acing basically as a 3d space time rudder. This would also explain why slapping an oversized AB kills your ability to turn. This would not even be that hard. Just shift the core off axis from the axis of thrust and bam you are turning. Just a few actuators to move the core around. This would explain why some ships appear to have drives that would result in a axis of thrust not passing through the center of gravity. If the core were offset then you would need offset thrust to compensate.
Anyway that’s my two cents on that. Ships banking in space.
