No, you cannot hear any sounds in near-empty regions of space
. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
Do you need atmosphere to hear?
Sound requires a medium to travel
. Sound is a vibration that travels through air. There is no sound in space because space is a vacuum and there is no medium for it to propogate in. If sound could travel through space, we could hear the sound of the sun and it would be pretty noisy.
Can sound waves travel through nothing?
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. So, the sound wave gets smaller and smaller until it disappears.
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.
Can humans hear sound in space?
No, you cannot hear any sounds in near-empty regions of space
. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
Does light travel as waves?
Light is made of little particles called photons.
These particles travel in waves
.
Where sound waves Cannot travel?
The correct answer is Vacuum. Sound vibration must travel through matter. Sound cannot travel through
a vacuum
. A vacuum is an area without any air, like space.
Does light fade in space?
The answer to your question is that
light does not ‘fade as it travels'
. Light from very distant stars is red – shifted – which I would not classify as ‘fading'. So that makes distant things look dimmer.
Why can't astronauts talk in space?
Because there is nothing out in space (like an atmosphere), the sound waves from one astronaut's whistling can't travel over to the other astronaut's ears
. That's why the astronauts use radios to communicate—even if they're floating in space right next to each other!
What happens if you talk in space?
In the spacecraft, there is plenty of air, so they just talk normally. When they are spacewalking, they talk by means of radios in their helmets.
The radio waves, again, have no problem in space, but they're not sound
. They're radio, which has to be converted into sound by the astronauts' headsets.
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's the loudest thing 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.
Can planets make sounds?
The planetary sounds we hear, are wavelike vibrations of air molecules occurring within the range of frequencies to which our ears are sensitive
, according to the BBC .
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)
.
Do black holes make sound?
Some produce relatively high pitches, because of the intensity of the gravitational waves, while others have a low bass rumbling
. Some even make the sound of a wobbling top as the two black holes swirl around each other, before eventually meeting and becoming totally absorbed into one another.
Is space completely silent?
In space, no one can hear you scream. This is because there is no air in space –
it is a vacuum
. Sound waves cannot travel through a vacuum. ‘Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears.
Is there gravity in space?
Because
gravity is everywhere in space
, objects in space are always falling: towards the earth, towards the sun, and towards the galactic center. There are two reasons that objects seem to be floating without gravity in space when they are really falling. Each galaxy is held together by strong gravitational forces.
Does sound travel as waves?
Sound waves traveling through air are indeed longitudinal waves
with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air do not vibrate in a transverse manner. Do not be misled – sound waves traveling through air are longitudinal waves.
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?
Do photons travel in waves?
Unlike a particle which has wave centers that create standing, longitudinal waves measured as mass,
the photon is a packet of traveling waves
.
Can sounds travel through gases yes or no?
Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.
Sound travels most slowly through gases
because the molecules of a gas are farthest apart.
Can sound pass through wood?
Sound travels fastest through solids such as wood or metal
. 3 1 The particles of solids , liquids , and gases vibrate differently . Sound waves travel about thirteen times faster in wood than air.
Can we touch sound?
Well, sound is vibration, and vibration is tactile.
You can feel sound by touch
. Put your hand on a piano while someone is playing.
Is light infinite?
Were there an infinite value for the speed of light,
light itself would not exist at all
. Mathematically, the wave equation that describes light as an electromagnetic wave would lose its time-dependence.
Is light always moving?
Light, no matter how high-or-low in energy,
always moves at the speed of light
, so long as it's traveling through the vacuum of empty space. Nothing you do to your own motion or to the light's motion will change that speed.
How far can sound waves travel?
The speed of the sound wave is 340 m/s. The distance can be found using d = v • t resulting in an answer of
25.5 m
.
