The interstellar void is not a pure void but is filled with diffuse plasma, the Interstellar Medium. Which, because plasma is electrically conductive at large length scales, you can brake against using gargantuan superconducting coils producing a magnetic field (which induces eddy currents in the plasma, producing a force opposing the direction of motion), slowing down like a magnet dropped into a vertical copper pipe: https://youtu.be/uh0bbW6S3BY?si=kE-1jYagQxGHIVMA https://youtu.be/uh0bbW6S3BY?si=kE-1jYagQxGHIVMA
