Scene Context: During the approach, the crew experiences nausea, "floating" inertia, and, upon crossing the threshold into the rupture, a near-total sensory collapse.
Essence of the Phenomenon: This concept moves beyond experimentally verified physics and relies on a hypothetical model of locally desynchronized metric nodes. In classical physics terminology, the closest analogy is tidal forces and gradients of inertial properties. However, in this scenario, they are amplified to a critical level where the central nervous system loses its ability to integrate the sensations of body, time, and space into a single continuous perception.
Theoretical Extrapolation: The model assumes the lifeboat is inside an unstable soliton bubble. If the two stringlet pairs do not operate in perfect synchrony, metric "beating" occurs inside the cocoon—a constant shifting of force vectors that the human body interprets as nausea, loss of inertial grounding, and sensory shock.
