In the absence of a medium, such as air or water, sound waves cannot travel through space as we typically understand them. Sound waves are mechanical waves that require a material medium to propagate.
In the case of sound waves traveling through air, for example, they are created when a source, such as a vibrating object, causes air molecules to oscillate. These oscillating air molecules then transfer their energy to adjacent molecules, creating a chain reaction of particle collisions that propagate the sound wave through the air.
However, in the vacuum of space, there are no molecules or particles to serve as a medium for sound waves to travel through. Therefore, in the typical sense, sound cannot propagate in the empty regions of space.
That being said, there are other forms of waves that can propagate through space, such as electromagnetic waves, including light waves. Unlike sound waves, electromagnetic waves do not require a medium and can travel through the vacuum of space.
