There is sound in space despite what they say

We were told there was no sound space, He is silent. But is this true?

The simple answer to that, of course, is yes: space is silent because it is empty. After all, what our ears perceive as “sound” is simply a pressure wave passing through a medium, whether solid, liquid or gas, vibrating the molecules within it.

When this pressure wave hits our ears, it causes the tiny hairs and bones inside to vibrate, sending an electrical signal to the brain that we interpret as sound.

But in a vacuum, where there are no liquid, solid or gaseous molecules to move, this cannot happen – so no sound is heard. But when you’re talking about space, the simple and easy answer is rarely exactly right – and that’s the case here too. This is because the space is not actually empty at all.

Yes, there are large areas of it, especially in interstellar and intergalactic space. But inside galaxies and nebulae are huge, swirling clouds of gas and dust, and the particles in those clouds are quite capable of rolling and swiping in a pressure wave — that is, sound — like their counterparts here on Earth..

In 2022, NASA released a recording of the black hole, derived from observational data from the Chandra X-ray Observatory.

Hear the sound of a black hole

Prove it Black holes produce a low-pitched sound that sounds (exactly) like something from the soundtrack of a 1950s B-movie sci-fi movie.

It’s a sound so low that your ear wouldn’t be able to hear it normally, so NASA used a process called “sonification” to make it perceptible to our ears. Gravitational waves and plasma waves (such as the solar wind, a stream of charged particles constantly emitted from our parent star) also provide a medium through which sound can travel.

It’s not loud enough to hear if you’re there, but clear enough to be spotted by ground-based radio telescopes. So, yes, it’s mostly quiet – but not really quiet.

How does sound travel and why does it not travel through space?

Like light, sound travels in waves. Unlike light waves, sound waves are referred to as mechanical waves.

In the case of sound waves, these mechanical waves come in the form of a vibrating wave that carries energy as it moves from one place to another. This wave must travel through what we call the medium, which in this case is through particles.

But let’s look at an example, to make it a little clearer.

If you play a string on the guitar, the string vibrates. This initial vibration sets off a chain reaction in the surrounding particles, not unlike the ripples caused by a pebble falling into a pond. Each affected particle then transmits vibrations to those around it, resulting in a transfer of energy.

The further the sound wave travels, the weaker the vibration becomes. This happens until the sound wave ceases to exist, due to the loss of a small amount of energy in each transfer between molecules. So for sound to travel, we need particles. These particles can make up a whole range of things, including water, gas, liquids or even solids.

but, Sound cannot travel through space because it is empty. If you played the guitar in space, you wouldn’t hear it.

There are no particles in the vast zero voids between cosmic bodies in space to vibrate, so the elementary vibrations of a guitar string will have nothing to carry, and no one will ever hear them.
