This isn't really right, the wave in the fork will reflect off the boundary, it doesn't just disappear. In atmosphere, most of the energy in a running fork reflects off the boundary with air as well, but in space essentially all of the energy stays in the fork, so the sound wave will just keep bouncing around and around inside. It's an impedance matching problem, and the acoustic impedance of space is essentially zero
