There Is No Sound In Space

Description: A famous physics phenomenon is included in the video below. A bell ringing in a bell jar will become quiet when the air is removed from the bell jar. Since sound is caused by vibrating material and all of the material has been removed from the bell jar there is no sound. This means that there is no sound in space. Recent discoveries from NASA has shown that there may be sound in space (due to oscillating interstellar gases) but it is not a sound humans can perceive on their own.
