Have you ever wondered if a tree falls in the forest and there is no one there to hear it, does it make a sound?

Have you ever wondered if a tree falls in the forest and there is no one there to hear it, does it make a sound?

Science answers: No! The universe has no "sound," only "vibrations." What you are hearing right now is your brain converting those vibrations into an experience you can understand. Without the brains of living beings... the entire universe would remain forever silent.

Here is an interesting fact from Hermann von Helmholtz's book *On the Sensations of Tone*: Sound is not an object; it is our body's response to the world around us. What do you think about this? Leave a comment below to discuss!
