How Fast Does Sound Travel Through Space?

by | Last updated on January 24, 2024

, , , ,

A: The speed of in a vacuum is

zero meters per second

, as sound cannot travel in a vacuum. Sound is a wave, which means it spreads through the vibration of particles in a medium, such as water or air. Since a vacuum is empty space, there is no medium for the sound to travel through.

Has NASA recorded sound in space?

The space agency used instruments on several probes (like Voyager and HAWKEYE) to record these waves. Then they put them together into a recording of a sound for all of us to hear. The result is a sound that is (frighteningly) akin to what you would expect to hear echoing as you sink into a black abyss.

Does sound travel faster in air water or space?


Sound travels faster in water compared with air

because water particles are packed in more densely. Thus, the energy the sound waves carry is transported faster.

Is there sound in deep space?

So, in order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate.

There is no sound there

.

What does space smell like?

Astronaut Thomas Jones said it “carries

a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous

.” Tony Antonelli, another space-walker, said space “definitely has a smell that's different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I …

What is the loudest noise in the universe?

The

1883 Krakatoa volcano eruption

was the loudest sound recorded on Earth, but there are much louder sounds in space, even though we technically can't hear them.

Are there vibrations in space?

The vacuum of outer space has essentially zero air. Because sound is just vibrating air,

space has no air to vibrate

and therefore no sound.

How cold is space?

Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that,

at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit)

.

Can you scream in space?

Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through.

If someone were to scream in space, the sound wouldn't even leave their mouths.

Can light travel through empty space?

Light can travel in a vacuum.

A vacuum is empty space. There are no molecules of air or anything else in a vacuum. Like all forms of electromagnetic waves,

light can travel through empty space, as well as through matter

.

How far can a yell travel?

The normal intelligible outdoor range of the male human voice in still air is 180 m (590 ft 6.6 in). The silbo, the whistled language of the Spanish-speaking inhabitants of the Canary Island of La Gomera, is intelligible under ideal conditions at

8 km (5 miles)

.

Can light heat and sound travel through space?


Sound cannot travel through empty space

; it is carried by vibrations in a material, or medium (like air, steel, water, wood, etc). As the particles in the medium vibrate, energy is lost to heat, viscous processes, and molecular motion.

Can you play music in space?

First things first,

it is possible

.

As there is air on a spacecraft, musical instruments should still work. However, it might not work if you try to play outside of a shuttle or space station. On a violin or guitar, the strings would vibrate without producing a sound.

How loud is a black hole?

But that number that is considerably smaller than the energy created by

1,100

of sound. Converting the energy of 1,100 decibels to mass yields 1.113×1080 kg, meaning that the radius of the resulting black hole's event horizon would exceed the diameter of the known universe. Voila!

How loud is the sun?

The answer might surprise you, as solar physicists estimate that the solar surface would be

approximately 100dB by the time it reaches Earth

! The enormity of the sun's surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.

Can you fart in space?

Surprisingly, that isn't the biggest problem associated with farting in space. Though

you're definitely more likely to worsen a small fire when you fart, it won't always injure or kill you

. The worst part about farting in space is the lack of airflow. Let's take a step back and remember how farting on Earth works.

Will a body decompose in space?


If you do die in space, your body will not decompose in the normal way, since there is no oxygen

. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.

Why can't you see the sun in space?

In space or on the Moon

there is no atmosphere to scatter light

. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.

CAN 1100 dB create a black hole?

With energy as great as 1100 dB,

it would create enough gravity to cause a black hole to form

, and an incredibly large one at that. Decibels are a logarithmic unit. That means 20 decibels isn't 2 times more powerful than 10 decibels, it's 10 times more powerful.

Does the sun make noise?


The Sun does indeed generate sound

, in the form of pressure waves. These are produced by huge pockets of hot gas that rise from deep within the Sun, travelling at hundreds of thousands of miles per hour to eventually break through the solar surface.

What is the quietest thing in the universe?

Microsoft currently holds the world record for the quietest place on Earth at -20dBA. Almost no part of the world is left untouched by sound. In fact, the only place in the universe with absolutely no sound is

where there is absolutely no mass

– which can only be found in a perfect vacuum.

Is there sound in a black hole?

The logical part of you would immediately react, ‘

it sounds like nothing

! ‘ because space is a vacuum and no sound can travel through there. While technically correct, modern technology can make the most improbable be possible.

Does heat travel through space?

Heat conduction and convection do not occur in space since there is no air in space.

Heat transfers in space, which is a vacuum, only by radiation

.

Can sound travel in all directions?

In short,

sound travels in both directions up and down

, sound is omnidirectional which means it can travel in any way and direction, however, there are some factors that may influence the direction of the sound.

How long is 1 hour in space?

One hour on Earth is

0.0026 seconds

in space.

Why is space dark?


Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes

. And with no light reaching the eyes, they see black. —What color is the sunset on other planets?

What happens if you bleed in space?

In space,

blood can splatter even more than it usually does on Earth, unconstrained by gravity

. Or it can pool into a kind of dome around a wound or incision, making it hard to see the actual trauma. (Fun fact: If you are bleeding more than 100 milliliters per minute, you are probably doomed.
