Can you hear sound in space?

Remember me (?)
Sound can only travel through a medium (solid, liquid or gas) by making their molecules vibrate. This therefore means that sound need any one of the three states of matter (solid, liquid or gas) in order to travel. Space being nearly a perfect vacuum, means sound waves can not travel from its vibrating source through the vacuum to another point in space or to the ear of an individual. In order for one to hear sound it must travel through gas particles which space has very few per cubic centimeter. This is very much less than that in the Earth’s atmosphere. So, can you hear sound in space ? or does sound travel in space? The answer is no, space is silent.[ex/]

sound is vibrating molecules to my understanding. such as O2 ect.
we do not understand the universe and sound enough to say not to that question, but i don't think that sound has mass, it is merely a force acting on mass.
