Well that question has definitely been answered for me after digging deep into this first chapter..."What question is that Dave?" Im glad you asked "If a tree in the forest falls and there is no one there to hear it, does it make a sound?" The answer is no it does not make a sound BUT it does cause fluctuations in the atmospheric pressure thus causing compression as it bounces to and fro at nearly 761mph, probably at some crazy frequency. So now I ask myself, what questions shall I answer from chapter2? Stayed tuned.........
