# Why Can T Sound Travel Through A Vacuum?

As defined by the scientific community, vacuum is defined as the empty space in which there are no matter particles present. Due to the fact that sound is a mechanical wave, a material medium is necessary for it to propagate. It is impossible for sound to travel in a vacuum because there are no particles present for vibrations to occur.

When it comes to space, sound does not travel at all. Almost no air can be found in outer space due to the vacuum of space. Because sound is simply the vibration of air, there is no sound in space because there is no air to vibrate.

## Why can’t sound waves be transmitted through a vacuum?

It is impossible for sounds to move in a vacuum because there is no medium via which they may be transmitted. Sound travels through matter due to the interplay of electrical forces between particles, which causes sound to move through matter. Because a vacuum is by definition devoid of substance, there is nothing for a sound wave to pass through in this environment.

## Can sound leap across a vacuum?

An article by David Shiga that I read presents a theoretical study conducted by Mika Prunnila and Johanna Meltaus of the VTT Technical Research Center that suggests sound may be able to jump between two objects constructed of piezoelectric crystals separated by a vacuum.

## How does a sound wave travel in space?

Sound is a compression wave, which means that it propagates in a material by compressing and then lengthening (or vice versa) the relative distance between two adjacent particles. In the vacuum of space, particles are too far apart to interact with one another, and hence moving one particle does not have an effect on the particle farther down the chain.

## What is the probability of sound being transmitted through space?

There is 0% chance that sound will be transferred into space that is completely devoid of all matter, sometimes known as a vacuum. Transverse waves in solids can propagate across a medium such as air, water, or solids, whereas longitudinal waves in air, water, and solids can travel through materials as longitudinal waves (see Longitudinal and transverse waves, below).
