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.

Is a supernova explosion loud?

Sound itself can only be transmitted through a medium and so in space we cannot hear a supernova. However since a supernova is a giant explosion triggered by the final death throes of a massive star, if we could hear it, we would hear an incredibly loud blast.

How much sound does a supernova make?

Sounds—which are simply pressure variations in a medium such as air or water—can't propagate in the vacuum of space, so the roiling surface of a star would make an impression on the eyes, but not the ears. A supernova would sound like 10 octillion two-megaton nuclear bombs exploding.

How strong is a supernova blast?

This explosion puts the “super” in supernova. A blast about 4.5 million light-years away has released about 10 times more energy than the sun will emit in its entire lifetime, making it the most powerful supernova ever spotted.

What is stronger than a hypernova?

Virus404 is 999,999,999,999,999,999,999,999 stronger than other viruses. Typical hypernovae can be anywhere from ten to a hundred times more powerful than a supernova. SUPERLUMINOUS SUPERNOVA (Hypernova): A burst 5 to 50 times more energetic than a supernova.

What is the biggest hypernova?

A cloud of expanding gas in space is the largest supernova remnant ever seen in the sky, a new study confirms. The Milky Way has some 300 known supernova remnants, each made of debris from an exploded star mixed with interstellar material swept up by the blast.

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 many decibels would destroy the universe?

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! No more universe.

What a black hole sounds like?

For the first time in history, earthlings can hear what a black hole sounds like: a low-pitched groaning, as if a very creaky heavy door was being opened again and again.

Can you hear explosion in space?

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. Exploding bombs, crashing asteroids, supernovas, and burning planets would similarly be silent in space.

What does 100 decibels sound like?

A 100 dB sound like that of a power tool or a car horn is 100,000 times louder than a sound that is 50 decibels like an average suburban home or a quiet room.

What does a dying star sound like?

"You can think of it as hearing the star scream as it gets devoured, if you like," Jon Miller, a University of Michigan astronomer, said in a statement according to Space.com. The answer is surprisingly simple: It sounds like a D-sharp played with a synthesizer about 16 octaves lower than the middle of a keyboard.

How loud is a star?

Throwing out an energy of 383 yottawatts per second, we get a translation of 290 decibels which makes for a very, very loud Sun indeed.

Why is there no 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.

Can you see a supernova on Earth?

Unfortunately, supernovae visible to the naked eye are rare. One occurs in our galaxy every few hundred years, so there is no guarantee you will ever see one in our galaxy in your lifetime. In 1987, a supernova called 1987A was visible in a nearby galaxy called the Large Magellanic Cloud.

CAN 1100 dB create a black hole?

With energy as great as 1100 dB, it would create enough gravity to cause a black hole to form, and an incredibly large one at that. Decibels are a logarithmic unit. That means 20 decibels isn't 2 times more powerful than 10 decibels, it's 10 times more powerful.

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.

How quiet is space?

Space isn't completely quiet — in fact, it's rather loud. Explore the anomalies that drown out all other noise. Sound doesn't travel in space. That's the knowledge most people have, however, it's not exactly true.

Will there be a supernova in 2022?

In 2022—only a few years from now—an odd type of exploding star called a red nova will appear in our skies in 2022. This will be the first naked eye nova in decades. And the mechanism behind it is fascinating as well.

Is a kilonova bigger than a supernova?

What matter is ejected by a kilonova does go out faster (30-60,000 km/s, versus about 10,000 km/s for supernova ejecta). On the other hand, a kilonova puts out much more energy in the form of gravitational waves, so they're bigger in that sense.
