If we (humans) and light can travel freely through the vacuum of space, then why does sound need a medium to travel through something and can’t travel in space?
In: Physics
I’m in no way qualified to make this statement, but I was always under the impression that sound came in the form of waves. These waves travel through particles in the air. Earth’s air is made up of oxygen and other gases to make it’s atmosphere, and when a noise happens within this atmosphere, the sound reverborates through the particles in the air on it’s way to you. In space, or even in a vacuum, there are no particles of anything to carry the sound to you, making it impossible to hear anything in space
