But for sound to be transferable it would have to interact with baryonic particles. Sound is the vibration of baryonic particles though a medium. It's a motion of energy that requires interaction between successive particles. If that energy reaches a point where it can no longer interact with nearby particles, it ceases to propagate. And because dark matter does not interact with baryonic particles, sound cannot propagate through it. |
Sorry to still go further on this but can't radio waves be a possibility to connect with frequencies of objects and other sources that emits them?
