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
.
Can you hear a supernova in space?
NASA's new project turns up the volume on space's most extreme phenomena.
In space, nobody can hear you scream
— or explode, or collapse, or slowly collide with a neighboring galaxy.
Can you hear explosions in space?
To travel to us from outer space, the wave must be able to travel through regions of space which are essentially vacuum (nothing there). Sound cannot do this, as it requires a medium to propagate in, so
we would not be able to hear the explosion
.
Would an explosion in space be silent?
Despite the violent nature of the Sun's constant explosions, Hadfield noted that even astronauts in space couldn't hear them simply due to the vast emptiness and vacuum of space. In other words,
the sound of the explosions produced by the Sun can't travel across space
.
What's the loudest sound in the universe?
Greg Salvesen. As far as I'm aware,
the Perseus galaxy cluster
is the current record holder for the loudest sound discovered in the Universe. Generating sound requires two conditions. First, there must be a medium that the sound waves can travel through, like air or some other gas.
How loud is a black hole?
A Sound Of
1,100 Decibels
Would Create A Black Hole Larger Than The Galaxy.
Does your head really explode in space?
Oxygen in the rest of your body will also expand. You'll balloon up to twice your normal size, but
you won't explode
. … Without air in your lungs, blood will stop sending oxygen to your brain. You'll pass out after about 15 seconds.
What does space smell like?
In a video shared by Eau de Space, NASA astronaut Tony Antonelli says space smells
“strong and unique
,” unlike anything he has ever smelled on Earth. According to Eau de Space, others have described the smell as “seared steak, raspberries, and rum,” smokey and bitter.
Why we Cannot talk in space?
In fact, the middle of space is
very quiet
. … 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!
Does the sun make noise?
The surface of the Sun produces sound waves
because the surface is convecting and this produces pressure waves that travel into the inner corona. But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles! …
What is the loudest thing in the world?
The Krakatoa volcanic eruption
: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB.
Why is 194 dB the loudest sound possible?
A sound of 194 dB has a pressure deviation of 101.325 kPa, which is ambient pressure at sea level, at 0 degrees Celsius (32 Fahrenheit). Essentially, at 194 dB,
the waves are creating a complete vacuum between themselves
.
What happens if you make a sound louder than 1100 dB?
“If you could produce a sound louder than 1100 dB, you would
create a black hole, and ultimately destroy the galaxy
“.
How loud would a supernova be?
If we suppose that the same fraction of a supernova's energy is converted to sound, and a supernova releases 10
44
joules, That means that about 10
44
/(840 billion) = 10
32
Joules of sound energy, thirty-two orders of magnitude greater than 120 dB, or
about 440 decibels
.
How loud are gunshots?
Multiple shots fired from a single gun will each be equally loud —
around 140 decibels in the case of a handgun
. A small-caliber gun, like a . 22 rifle, will generally be quieter than a larger one, like a 12-gauge shotgun.
How long is 1 hour in space?
How is 1 hour in space equal to
7 years
on Earth.
