Sound does not travel at all 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. If you are sitting in a space ship and another space ship explodes, you would hear nothing.
Why doesn't sound travel through outer space but light does?
As the vibrations of the particles reach your ear, your ear drum receives the vibrations which the brain then interprets as sound.
In the vacuum of space, there are no (or very, very few) particles to vibrate
, so sound cannot travel through this medium.
Has sound been recorded in space?
Space is a virtual vacuum. Since there isn't anything to conduct sound waves in space (there's nothing to transfer the sound vibrations from the source to your ear), many people assume that sound does not exist in the vastness of the cosmos. But
there is sound in space
.
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.
Can astronauts hear each other in space?
When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but
the other astronauts would not hear the noise
. In fact, the middle of space is very quiet. Sound travels in waves, and it moves at different speeds through air or water or other materials.
Can sound travel through empty space?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they
cannot travel through empty space
, where there are no atoms or molecules to vibrate.
Can light waves travel in space?
Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that
light can travel through a vacuum? a completely airless space
.
What does space smell like?
A succession of astronauts have described the smell as ‘… a rather pleasant metallic sensation … [like] … sweet-smelling welding fumes', ‘burning metal', ‘a distinct odour of ozone, an acrid smell', ‘walnuts and brake pads', ‘gunpowder' and even ‘burnt almond cookie'.
Where is Voyager 1 now?
NASA's Voyager 1 spacecraft is currently
over 14.1 billion miles from Earth
. It's moving at a speed of approximately 38,000 miles per hour and not long ago passed through our solar system's boundary with interstellar space.
What does space taste like?
In spite of its namesake, space experts believe that chocolate is not the commanding taste of the Milky Way. Although this may be a disappointing revelation, the taste of the galaxy is actually reputed to be
far fruitier — very similar to that of raspberries
, reveals The Guardian.
Do we age faster in space?
Scientists have recently observed for the first time that, on an epigenetic level,
astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
Why is Pink Floyd first in space?
Cosmonauts Sergei Krikalyov and Alexander Volkov insisted on taking a cassette copy of the album and playing it as they completed their mission. As a result,
Russian cosmonauts took the Pink Floyd album with them onto the MIR space station which marked the first rock album that was ever played in space.
How quiet is it in space?
While space is
more silent than you could ever imagine
, it's not completely devoid of sound. Sound waves cannot travel through space, but there are some infinitesimally small regions where sound can exist, under very specific conditions.
Why can't astronauts whistle on the moon?
“You can't whistle because the air pressure in the suit is only 4.3 [pounds per square inch], and normal atmospheric pressure is 14.7 psi, so there are not enough air molecules blowing by your lips to make a sound,” he said. What would Barry have whistled if he could have?
Can an astronaut fart in space?
The official verdict on gas in space: No burps, more farts, and no,
you can't use your flatulence to propel you around the shuttle
.
Can astronauts talk in space without any special device?
Answer: In space, there will be no medium for sound waves to travel through, only vacuum.
Because sound cannot travel through vacuum, it must be heard using special equipment.
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.
What Cannot sound travel?
Sound can move through the
air, water, or solids
, as long as there are particles to bounce off of. However, if there are not particles to bounce off of, it can't move. There is no sound in the vacuum of space, because there is nothing to vibrate the sound.
Is there sound on the Moon?
However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don't interact with one another). Thus
there is no sound on the Moon
.
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.
Is light infinite?
Answer 4:
Ordinarily, no, light will continue on its path forever unless it runs into something
. Now, this said, very powerful photons (i.e. gamma rays) can spontaneously transform into particle-antiparticle pairs.
Why can light travel in an 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.
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.
Does space have a bottom?
Space has no floor
.
However, it's not really an endless pit, either, because gravity doesn't pull in one direction. It pulls toward objects that have mass.
Do astronauts pass out during launch?
He also noted that
it's not possible to pass out during the launch
, because you are being pushed into space while lying on your back, so your blood doesn't end up draining out of your brain. Also, he said it takes about 15 seconds to go from a sunny day to complete darkness.
