No, sound does not stay in one spot in space. Sound is a mechanical wave that requires a medium, such as air, water, or a solid, to propagate. In the absence of a medium, such as in the vacuum of space, sound waves cannot travel and propagate as they do in a medium.
In space, where there is a near-vacuum, sound waves cannot transmit and propagate like they do in Earth's atmosphere. Without molecules or particles to vibrate and transmit the wave energy, there is no medium to carry and sustain sound waves. As a result, sound cannot travel through the vast empty regions of space.
However, it's worth noting that space is not entirely devoid of particles. There are still extremely low-density particles, such as atoms, ions, and dust particles, scattered throughout space, especially in interstellar and interplanetary regions. Sound waves can potentially propagate through these sparse particles, but the energy transfer would be highly inefficient due to the vast distances and low densities involved.
In summary, sound waves cannot travel in the vacuum of space because they require a medium to propagate. In the absence of a medium, sound does not stay in one spot but simply does not propagate at all.
