In the vacuum of space, those sounds would not reach a spacecraft's hull, as there is no air to carry the vibration. Light is an electromagnetic wave that travels perfectly through a vacuum.
Can Sound Travel Through Outer Space? The Reality of Sound Waves in Vacuum
Understanding the boundary between wave types allows researchers to map the distribution of invisible dark matter and trace the dynamics of galaxies that would otherwise remain silent. Misconceptions in Media and Entertainment Cinema and television frequently depict dramatic space battles where the roar of engines and the impact of explosions are heard clearly through the vacuum.
However, the density of this interstellar medium is incredibly low—trillions of times less dense than the air we breathe. When one particle is displaced, it collides with or pulls on its neighbor, transferring kinetic energy in a domino effect.
Can Sound Travel Through Outer Space in a Vacuum?
Sound requires a medium such as air, water, or solid objects to travel. Light, radio waves, and X-rays belong to the latter category, which consists of oscillating electric and magnetic fields.
