How did NASA get audio of a black hole?

The viral audio, to be clear, is not a recording: it has been produced by 'sonifying' data taken from NASA's Chandra X-ray Observatory (another space telescope). The audio produced was originally 57 octaves below middle C, which meant the frequency had to be raised 'quadrillions' of times to be heard by human ears.

How did NASA get sound from black hole?

A new sonification turns X-ray “light echoes” from a black hole into sound. Rings of X-rays seen by NASA's Chandra and Swift observatories show the echoes. Material around a black hole can generate bursts of X-rays. The X-rays reflect off clouds of gas and dust like beams from headlights can in fog.

Has NASA captured sound of black hole?

NASA has released a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years away. The black hole is at the center of the Perseus cluster of galaxies, and the acoustic waves coming from it have been transposed up 57 and 58 octaves so they're audible to human hearing.

How is black hole sound found?

The black hole at the centre of the Perseus galaxy cluster has long been associated with sound. In 2003, astronomers discovered that the pressure waves sent out by this black hole cause ripples in the cluster's gas that can be translated into a note, albeit, one that humans cannot hear.

How loud is a black hole?

Hailey et al. 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.

Physics expert explains how NASA got sound from a black hole

Did NASA record sound in space?

NASA Has Captured 'Actual Sound' in Space and It's Honestly Terrifying. Vice.

How did scientists hear a black hole?

In its sonifications of the black hole in the M87 galaxy, which was first imaged in 2019, NASA created audio using X-ray, optical light and radio wave data from ground and space telescopes.

Is black hole sound like om?

While everybody had their theories about how it sounds, many users on Twitter claim they hear 'OM'. Sharing the video, NASA wrote, "The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel.

Can we hear black holes collide?

It is possible to hear them, because their wavelengths have been shifted all the way into the human range of hearing by MIT professor Scott Hughes. Drawn together by their immense gravity, nearby black holes will swirl faster and faster until they are finally absorbed completely into one another.

What is the loudest sound in space?

The loudest sound in the universe definitely comes from black hole mergers. In this case the “sound” comes out in gravitational waves and not ordinary sound waves.

Would entering a black hole hurt?

The fate of anyone falling into a black hole would be a painful “spaghettification,” an idea popularized by Stephen Hawking in his book “A Brief History of Time.” In spaghettification, the intense gravity of the black hole would pull you apart, separating your bones, muscles, sinews and even molecules.

What is inside black hole?

Black holes have two parts. There is the event horizon, which you can think of as the surface, though it's simply the point where the gravity gets too strong for anything to escape. And then, at the center, is the singularity. That's the word we use to describe a point that is infinitely small and infinitely dense.

Can a really loud sound create 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! No more universe.

Will two black holes collide in 3 years?

The astronomers in the study predict that if the signal is a true indication of a colliding binary supermassive black hole system, they will merge in an incredibly short period of three years.

What happens if 2 super black holes collide?

Logically, these giant black holes—each millions to billions of times heavier than our sun—must collide and merge, too. Such mergers can channel huge volumes of material into the black holes, sparking violent astrophysical outbursts that shape star formation and other processes in their host galaxies.

Is the universe a sound?

Einstein's theory of spacetime tells us that the real universe is not silent, but is actually alive with vibrating energy. Space and time carry a cacophony of vibrations with textures and timbres as rich and varied as the din of sounds in a tropical rain forest or the finale of a Wagner opera.

Does space have a sound?

Space Environment

So, in order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate. There is no sound there.

What sound would the sun make?

The Sun is a roiling ball of plasma and gas and if you could survive the temperatures within it, it would probably sound like a gigantic pot of boiling jam being hit by a nuclear bomb! The sound doesn't reach us across the vacuum of space, but there are slower waves that we can see moving on the surface.

What did Einstein think black holes were?

According to Einstein's theory of general relativity, massive objects like black holes distort space and time, which both magnifies the light and forces it to travel on a different path than it would otherwise — this is known as gravitational lensing.

What did Einstein think was in a black hole?

Over a century ago, Albert Einstein predicted that the gravitational pull of black holes were so strong that they should bend light right around them. Black holes don't emit light, they trap it; and ordinarily, you can't see anything behind a black hole.

Did Einstein think black holes existed?

The concept that explains black holes was so radical, in fact, that Einstein, himself, had strong misgivings. He concluded in a 1939 paper in the Annals of Mathematics that the idea was “not convincing” and the phenomena did not exist “in the real world.”

Why is space quiet?

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.

Why is space infinite?

Because space isn't curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.

Can humans hear 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.

How loud is 1 decibel?

When it comes to human hearing, sounds at or below 70 dB are considered safe. As 1 decibel is under this limit, this level is also considered safe for human hearing. Sounds at or above 85 dB are considered potentially dangerous if your exposure to them is extended (i.e., several hours per day).
