What is the loudest sound in space?

The loudest sound in space isn't a single explosion but powerful pressure waves from a supermassive black hole in the Perseus galaxy cluster, a B-flat note 57 octaves below middle C, generated by ripples in hot gas, with energy equivalent to 100 million supernovas, discovered by NASA. While not audible to humans (requiring conversion), the most powerful event is a black hole merger, releasing more energy than all the stars in the observable universe, detected as gravitational waves, which scientists convert to sounds.

What is the loudest sound on space?

The sound waves emanating from the black hole in the Perseus galaxy cluster have been measured at 57 octaves below middle C. While we can't hear this sound directly, it has been detected by astronomical instruments and represents the most powerful sound waves in the cosmos.

Is 310 dB possible?

Yes, 310 dB is possible as a measurement for extreme events like the Krakatoa eruption, but it's not a "sound" in the normal sense; it's a massive shockwave, as normal sound in air maxes out around 194 dB before air molecules can't compress further, creating a vacuum and transforming into a destructive blast wave, with Krakatoa's source reaching this estimated level, which was heard thousands of miles away as a powerful pressure wave.
 

What is the loudest sound on Earth?

The loudest sound ever recorded on Earth was the 1883 volcanic eruption of Krakatoa in Indonesia, estimated at 310 decibels (dB), heard thousands of miles away, rupturing eardrums and circling the Earth multiple times, far exceeding the 194 dB limit for typical sound waves by converting into powerful shockwaves.
 

How loud would 1000 decibels be?

For reference, under normal conditions the loudest possible sound (on Earth) is 194 dB. A sound of 1000 dB would be loud enough to create a black hole larger than the galaxy. We wouldn't be able to get a bark that loud even if we covered every inch of earth with clones of champion barker Charlie.

8 Strangest sounds recorded in space

Can 1100 decibels 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. Matter and energy are interchangeable (E=mc^2). The black hole doesn't care if it's a great amount of energy or mass, it will still form.

What does "cachalot" mean?

The sperm whale or cachalot (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator.

Can a whale call Deafen you?

Did you know that the clicks of sperm whales can be as loud as 230 decibels. To put this into perspective, a jet taking off registers at around 150 decibels from 25 metres, enough to rupture an eardrum. The most powerful sperm whale clicks will not only deafen you they can vibrate the fragile human body to pieces!

Is the 52 Hz whale real?

In the 1980s, scientists discovered a mysterious whale singing at 52 hertz, a frequency no other whale uses. 🐋 They named it the Loneliest Whale in the World, believing it roams the seas unanswered.

What dB is a gunshot?

A gunshot's decibel level typically ranges from 140 to over 170 dB, depending on the firearm, causing immediate hearing damage without protection, with smaller firearms often around 140-160 dB and larger rifles exceeding 170 dB, far above the 85 dB threshold for safe listening.
 

Can 1100 dB destroy a galaxy?

For you to destroy the galaxy, you need to expend enough energy to destroy the galaxy. There are no shortcuts in physics. A 1,100 dB sound would require an astronomical amount of energy, beyond comprehension.

How loud is a bomb?

A 1-Ton TNT Bomb: An explosion from this bomb would measure 210 dB. 2. A 5.0 Richter Earth Quake: A strong earthquake such as this reaches a decibel level of 235.

Is 1 hour in space 7 years on Earth?

Generally, no. Different regions of space experience different degrees of time dilation, but the differences between most regions are negligible. It is only when objects are very close to very massive objects (e.g., black holes) that time can (theoretically) be dilated to this extent (e.g., the movie Interstellar).

Is space 100% silent?

Space isn't 100% silent because it contains plasma and has pressure waves, but it's essentially silent to human ears because sound needs a medium (like air) to travel, and the near-vacuum of space lacks enough particles for human-audible sound waves, though NASA converts cosmic pressure waves into sounds we can hear.
 

What is the deadliest thing in space?

Black Holes. Find out why we can't see them! At the center of most galaxies is one of the strangest and deadliest things in the universe: a black hole.

Can a blue whale live 200 years?

No, blue whales don't typically live 200 years, with their average lifespan around 80-90 years, though some can reach 110; the whale known for living 200+ years is the Bowhead whale, the longest-living mammal, not the blue whale. Blue whales, despite their massive size, live long but not exceptionally so compared to the arctic bowhead, which can exceed two centuries.
 

Can sperm whale clicks hurt you?

Ultimately, my experience with these whales over the last decade and hundreds of hours in the water with them reveals that there is practically a zero-risk in any harm, pain, or damage to the human body from sperm whale clicks.

Is it illegal to talk to whales?

Many people seek the opportunity to engage in interactions with wild marine mammals. These interactions are not only illegal, but are also potentially harmful to the animals as well as to the people. Feeding dolphins in the wild can be particularly harmful.

Is whale sperm a thing?

Whale Reproduction. Over the past few decades, it has been reported that whales release between 40 and 400 gallons (1.51 m³) of sperm during a single mating act, with only about 10% entering the female.

What is the closest DNA match to whales?

Whales' closest living DNA relatives are hippopotamuses (hippos); both share a common ancestor that was a four-legged, even-toed hoofed land mammal, making hippos their nearest living kin, despite their vastly different modern lifestyles. This connection is supported by genetic evidence, showing whales (cetaceans) evolved from within the Artiodactyls (even-toed ungulates), with hippos branching off as the most closely related group.
 

What animal can dive the deepest?

The deepest diving animal is the Cuvier's beaked whale, holding records for both the deepest (2,992 meters/9,816 ft) and longest (over 2 hours) dives for any mammal, followed closely by the Southern Elephant Seal, while the deepest fish ever filmed is a type of snailfish found at over 8,300 meters. These creatures have incredible adaptations, like flexible ribs and specialized blood, to withstand extreme pressure and find food in the dark, deep ocean. 

How loud are two black holes?

When two black holes slam together, they don't make a sound. And yet, this is what we hear if we listen closely. Let's listen again. That “chirp” is what we heard from two black holes that slammed together about a billion light-years from Earth.

How much gravity is needed to create a black hole?

Black holes are objects with high gravitational forces, but we don't know how much minimum gravity is required to form one. Here, we quantified it and report that if the gravity is $≥ c^4/G$ at any point of the object, that object will be a Schwarzschild black hole.
