What Will Finally Stop Voyager?

Voyager 1 is losing power. Within a decade, its last instrument will go silent, its radio will die, and the farthest human-made object will become a cold, dark shell drifting through interstellar space. Most people assume that is the end of the story. It is not. Losing electricity does not mean losing speed. Voyager has been coasting on momentum borrowed from Jupiter and Saturn since 1980, and in the near-perfect vacuum between the stars, almost nothing pushes back. So what could actually stop it? Not the thin gas of the interstellar medium. Not the fading gravity of the sun. Not the slow erosion of cosmic dust. This documentary traces Voyager's future from its final engineering crisis through the Oort Cloud, past foreign stars, across full orbits of the Milky Way, through the collision with Andromeda, and into timescales so vast they stretch toward the heat death of the universe itself. Along the way, it reveals a strange and unsettling truth: in a cosmos with no friction and no absolute state of rest, stopping may be the one thing the universe cannot do to this small machine. The answer to "what will finally stop Voyager?" is far stranger than you expect.
