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.
So do not be fooled by space movies where you can hear the loud explosion in space of a space ship or planet, spaceships engine giving off sounds or the firing of guns. This myth of sound in traveling in space, is spread mostly by Hollywood space movies and also by TV. This is only added for special effects as sound effects and music greatly enhance the psychological effects that movies have on an audience thus, making the movie a lot more interesting and entertaining.Related Articles:What is the Kinetic Molecular Theory of Matter?What are the Three States of Matter?How does sound travel?What is Sound?Is outer space a perfect vacuum?
