Going back to the asteroid one last post on this.

Just rewatched the asteroid field scene. I understand the perspective argument, but we don't have enough information to dissect the physics. You don't know how fast the MF is flying, whether the big one is stationary or moving, the direction or speed at which the smaller ones are moving, etc. We see the MF approaching "one of the big ones" through the cockpit, and then we see just how massive it is in the next shot. That's all we really need to enjoy the scene.

Could it be tweaked? Possibly by having it remain roughly the same size the whole time we see it through the cockpit. I've never had any trouble accepting it as presented, though, especially since it is only on screen for a few seconds before the exterior shot.
