The question of whether or not a tree that falls in the forest makes a sound - if there is nothing or no one around to hear it - comes up frequently at my house.
So, my question is: is there any way to "prove" or "dis-prove" this using physics? If it can be proven what is the answer?
My idea is yes, of course it makes a sound even if there is nothing to sense it! However, my parents seem to think that if there is nothing to "take in" the sound waves, there is no sounds.
