Hello again To my understanding, sound is vibrating particles in the air. Does that mean that in Space you can't hear anything because its mainly a vacuum?
Well, in one sense it's true but in another it's not.
For example, if you were outside a spaceship and rang a simple bell, that sound would not propagate.
However, if while outside you set-off a gaseous explosion, the expanding gases would provide a medium for sound waves.
In other words, if 2 spacecraft were relatively close to each other and one exploded, the violently expanding gases and materials impacting the second craft would most definately be "heard" by those inside when the vibrational impact affects the hull and then the air inside the second craft.
Yes, but there isn't enough coordinated/coherent energy in those collisions to create audible sounds. The vibrations have to be in phase to cause your eardrum to vibrate.Now my brain is hurting. Are vibrations in particles caused by other particles banging into them? Does sound genterate every time a particle vibrates?
But would the vibrations stop after a few minutes to where the atoms can't collide to make a sound?
