Modern physics considers interstellar travel virtually impossible due to g‑forces, travel time, and fuel requirements. This paper presents a hypothetical alternative: synchronous movement. Based on a hypothesis by Alexander Belik, the concept suggests that matter can enter a state of global synchronisation through a non‑electromagnetic field, losing inertia and localisation. A crewed ship would vanish from one point in space and appear at another without trajectory motion, g‑forces, or conventional fuel. Navigation takes time, but travel time is zero. The concept is logically consistent but contains six white spots. Three simple experiments are proposed for empirical verification. --- Keywords: synchronous movement, interstellar travel, inertia cancellation, non‑local field, white spots, crewed starship, Ksenolog.
