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.
How fast does sound travel in space?
The speed of sound 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.
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 astronauts hear 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 you smell a fart in space?
In space, no one can hear you fart (but
they can smell it
). They can! Zero gravity could even help them to travel, if the aroma was spreading through a virtual vacuum. Smells travel by the movement of individual aroma molecules.
Is fire possible in space?
Fires can't start in space itself because there is no oxygen – or indeed anything else – in a vacuum
. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.
Can you smell in space?
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 …
Which waves can travel through empty space?
Electromagnetic waves
differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
What is the space where sound waves are unable to travel?
Sound cannot travel through
a vacuum
. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
Do sound waves move 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.
Why astronauts Cannot talk in space?
Now, when the two astronauts are floating close to each other in space, without the use of any special device, they cannot talk to each other
because there is vacuum between them
. As there is vacuum, it means there are no molecules or particulate matter between them for the sound to travel.
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.
How quiet is it in space?
In essence, there's no medium for the vibrations to travel through. So sound does travel in space, it's just too difficult to hear. The truth is, however, space is
extremely loud
; just not via mechanical waves.
Can you get pregnant in space?
As a result
NASA's official policy forbids pregnancy in space
. Female astronauts are tested regularly in the 10 days prior to launch. And sex in space is very much frowned upon.
How do astronauts wipe their bum?
Today, astronauts at the International Space Station go to the bathroom into a little plate-sized toilet hole, and
a fan vacuum sucks their excrement away
and a separate funnel equipped with a fan suction their pee away.
Why can't astronauts burp in space?
On Earth, gravity pulls liquids and solids to down to the bottom of our digestive systems, while gases stay up top and get forced back up the esophagus as a burp. That can't happen in space.
Without gravity to separate them, “the air, food and liquids in your stomach are all floating together like chunky bubbles.
How long is 1 year in space?
**One year in space would be
365 days
/1 year on earth…..
Do you age 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.
How does the sun burn if there is no oxygen in space?
Since there is a vacuum in space, there is no oxygen there, so how does the sun burn?
It releases energy because of nuclear fusion in it's core where hydrogen turns into helium
. That is how the sun becomes hot amd bright.
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.
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.
What happens if you take your helmet off in space?
Removing the helmet would leave
permanent ear damage and the lack of oxygen would damage many organs
. Also, if the astronaut is in a very cold part of the universe, the astronaut would start to freeze. While low pressure would lead to the boiling of his blood, saliva and in the end organs.
What causes a sound wave?
When an object vibrates, it causes movement in surrounding air molecules
. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules. This “chain reaction” movement, called sound waves, keeps going until the molecules run out of energy.
Can radio waves pass through human body?
RF radiation has lower energy than some other types of non-ionizing radiation, like visible light and infrared, but it has higher energy than extremely low-frequency (ELF) radiation.
If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to burns and body tissue damage
.
Why can light waves travel through 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.
