Can You Hear Sounds in Outer Space?

Science Fair Project Idea

Scientific Method

Have you ever wondered what sounds you can hear in space? The answer is simple: none! In outer space there is utter silence. There are no sounds of traffic jams or thunderstorms or crashing waves. No buzzing bees or babies crying. Just silence. In this experiment, you will discover why empty space is void of sound and prove it with the help of the microphone in your phone and a sensor app. Read more
