How loud is 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.

Is space quiet or loud?

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.

Is there any sound in space?

No, there isn't sound in space.

This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.

How loud is a black hole?

Converting the energy of 1,100 decibels to mass yields 1.113x1080 kg, meaning that the radius of the resulting black hole's event horizon would exceed the diameter of the known universe. Voila!

What is the loudest sound 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 loud is 1100 decibels?

40 decibels is 10 times more powerful than 30 decibels. Each time the decibel number goes up by 10, the power of the sound is multiplied by 10. The number 1100 is like starting with 10 decibels, and adding 10 on 109 times. That means 1100 is 10109 times more powerful than 10 decibels.

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. You can go louder than 194 dB, but that's not technically a “sound” anymore.

Can we create 1100 dB?

so to get 1100 dB, you need to explode 1*10^85 atomic bombs or 1 with 85 zeros on the right. Yes, that will create a blackhole.

How noisy is the sun?

The answer might surprise you, as solar physicists estimate that the solar surface noise 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.

What happens if 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.

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'.

Is it dead silent in space?

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 space completely dark?

Above the Earth's atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn't absolutely black. The universe has a suffused feeble glimmer from innumerable distant stars and galaxies.

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.

How loud is 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.

What if space was breathable?

At that speed, friction would strip Earth of its atmosphere as it caught fire. Since space is breathable, we might be able to survive if it weren't for the fact that Earth would also lose its kinetic energy, coming to a standstill in space the same way bullets do as they eventually fall back to Earth.

How loud is a supernova?

If we suppose that the same fraction of a supernova's energy is converted to sound, and a supernova releases 1044 joules, That means that about 1044/(840 billion) = 1032 Joules of sound energy, thirty-two orders of magnitude greater than 120 dB, or about 440 decibels.

Do black holes make sound?

Now, humans can hear the sound of the black hole forever. Since 2003, the Perseus Galaxy has been known to have a noise-making black hole at its centre. At the time of discovery of this black hole, scientists had observed it for 53 hours.

Can sound really create a black hole?

A sonic black hole, sometimes called a dumb hole or acoustic black hole, is a phenomenon in which phonons (sound perturbations) are unable to escape from a region of a fluid that is flowing more quickly than the local speed of sound.

How loud is a blue whale?

Not only can baleen whales emit calls that travel farther than any other voice in the animal kingdom, these giants of the deep also create the loudest vocalisations of any creature on earth: the call of a blue whale can reach 180 decibels – as loud as a jet plane, a world record.

How loud is Krakatoa?

The pressure wave generated by the colossal third explosion radiated out from Krakatoa at 1,086 km/h (675 mph). The eruption is estimated to have reached 310 dB, loud enough to be heard 5,000 kilometres (3,100 mi) away.
