Sound waves require a material medium to propagate, so in absolutely empty space, sound waves cannot be produced. In the absence of any particles or molecules to vibrate and transmit the mechanical energy, there would be no medium to carry the sound waves.
In scientific terms, sound is defined as a mechanical wave that travels through a medium by the vibration of particles in that medium. Without a medium, there would be no particles to vibrate, and thus, no sound waves can be generated.
This understanding is supported by experimental evidence and scientific principles. For example, in outer space where the density of particles is extremely low, sound cannot travel because there is no medium to propagate the waves. Astronauts and space probes cannot transmit sound as we experience it on Earth since the vacuum of space lacks the necessary particles to transmit the mechanical vibrations.
It's worth noting that while sound waves cannot propagate in empty space, electromagnetic waves, such as radio waves, can travel through vacuum. Electromagnetic waves do not require a medium and can propagate through the vacuum of space, allowing us to receive radio signals and communicate with space probes and satellites.
