Is the space completely silent?

---

Many people will hear expressions in space, no one can hear you scream.

Like many others before you, you can simply accept this true without thinking more about this topic.

Some may even have fallen further and know that the space is silent because the sound cannot go through the vacuum.

While these two are right, you've ever wondered why?

To go to the end of this, we need to take a closer look at the science behind all.

So space is a vacuum, but what does that mean?

We all know about this are called space, but what exactly is that?

To put it simple, space is everything that you can find the atmosphere outside the earth.

Although filled with stars, planets, asteroids and so on, the space is called vacuum.

A technical vacuum means a completely no problem space.

Inside the vacuum has absolutely nothing.

So how is a vacuum space, if there are so many cosmic body filling the night sky?

How to sound traveling how, and why can't it go through space?

In case of sound waves, these mechanical waves have energy vibration waves when it moves from one place to another.

This wave must go through what we call a means, in this case through the particles.

Consider an example, to make it a little clearer.

If you play a string of a guitar, vibrating string.

Each particle is affected then turns the vibrations up the vibrations around it, switching energy.

The wave sounds farther, the weaker vibration becomes weaker.

This happens until the sound wave no longer exists, due to a small amount of energy lost in each transfer between particles.

So to have sound to travel, we need the particles.

While most of the space is a vacuum, and therefore completely silent, there are still some areas that can hear the sound.

But wait, this doesn't go against everything I have said so far?

During the clouds of the universe can be found.

In this spatial space cloud, it can give clustering gas and dust, and therefore dense.

This means it can really have enough particles close enough to sound that happen, and even move a small distance.

An example of where sounds occur in space are in black holes, but unfortunately, it can't be heard.

This sound was first recorded in 2003 at NASA's Chandra X-ray observatory, and it came from Perseus Galaxy over 250 million years of light.

The sound is measured as B-Flat, but at a much lower frequency level than physically for people to listen.

While the space is silent you can imagine, it doesn't completely have no sound.

The sound waves cannot go through space, but there are some extremely small areas where sound can survive, in very specific conditions.
