Scene Context: Upon exiting the transition, it is revealed that the lifeboat has arrived not near Earth, but near the TRAPPIST-1 system.
Essence of the Phenomenon: To a layman, an error of this magnitude sounds absurd, but within the model, it is the consequence of an imprecise metric transition, not a standard navigational miscalculation. TRAPPIST-1 is a real planetary system located approximately 40 light-years from Earth. Consequently, for Les, this news does not mean "we drifted slightly off course," but rather the absolute collapse of any hope of returning home.
