# Quick Answer: Can You Hear A Black Hole?

## How loud is 1100 decibels?

A 1100 decibel sound would require so much air/matter and the compression would be so intense that all that mass would be compressed into a super massive black hole.

Because decibels is a logarithmic scale.

100 decibels is a loud noise.

1100 db is 10 99 times more powerful than a loud noise..

## What would happen if a supernova hit a black hole?

A black hole is actually the end result of a supernova. … If the star that went supernova and the black hole were initially in orbit around each other, they would possibly remain so as a binary system, or the explosion may propel the second star away from the black hole.

## What’s on the other side of a black hole?

The event horizon is a proposed boundary around a black hole. On the other side of it, the gravitational pull of the black hole is so strong that, in order to escape it, an object would have to be moving faster than the speed of light, a feat that almost all physicists agree is impossible.

## How many decibels can kill you?

150 decibels is usually considered enough to burst your eardrums, but the threshold for death is usually pegged at around 185-200 dB. A passenger car driving by at 25 feet is about 60 dB, being next to a jackhammer or lawn mower is around 100 dB, a nearby chainsaw is 120 dB.

## Does time exist in a black hole?

For outside observers, a black hole is one solidary element, and there is no proper time inside the black hole, but there is only the observed coordinate time according to our spacetime coordinates.

## Can a black hole swallow the Earth?

If nothing can escape from a black hole, then won’t the whole universe eventually be swallowed up? … There is no danger of the Earth (located 26,000 light years away from the Milky Way’s black hole) being pulled in.

## What would a black hole do to Earth?

If a black hole were to form from the Earth itself, it would create an event horizon just 1.7 centimeters in diameter. … Eventually, some time later, any object at rest — no matter how far away from the event horizon it initially was — will cross that horizon and encounter the central singularity.

## What are the 4 types of black holes?

There are four types of black holes: stellar, intermediate, supermassive, and miniature. The most commonly known way a black hole forms is by stellar death.

## What happens to sound in a black hole?

A sonic black hole, sometimes called a dumb 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.

## Can you physically see a black hole?

You can’t see it (see paragraph 2 above). Every black hole has a minimum distance from it where, to escape its gravity, you’d need to move at the speed of light. Nothing can do this, which is why black holes are black (and why they’re holes, for that matter). This distance is called the event horizon.

## Do black holes die?

Black hole evaporation. … If black holes evaporate under Hawking radiation, a solar mass black hole will evaporate over 1064 years which is vastly longer than the age of the universe. A supermassive black hole with a mass of 1011 (100 billion) M ☉ will evaporate in around 2×10100 years.

## Has anyone been in a Blackhole?

But if you’re going to try it, you need to know this one small catch. Scientists say humans could indeed enter a black hole to study it. Of course, the human in question couldn’t report their findings—or ever come back.

## What it looks like inside a black hole?

The black hole bends light around it, creating a circular shadow. General relativity predicts that the shadow ought to be round to within 10%, says Avery Broderick, an EHT member and astrophysicist at the University of Waterloo in Canada, whereas alternative theories of gravity predict distorted, noncircular shapes.

## Are black holes silent?

To our instruments, black holes are far from black, and research suggests they are also far from silent. … Instead, as an object is pulled into a black hole, the energy of its motion is transformed into sound. We cannot hear these sounds, as space is silent, but we can “see” them with our telescopes.

## Do we know what a black hole sounds like?

“As the black holes spiral closer and closer in together, the frequency of the gravitational waves increases. Scientists call these sounds ‘chirps,’ because some events that generate gravitation waves would sound like a bird’s chirp.” Black holes can be phenomenally big.

## What is inside a Blackhole?

A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.

## Is 1100 dB possible?

It’s not possible as a continuous sound in air because the maximum overpressure is double atmospheric, with the troughs a vacuum, which works out at 194 decibels. The answer is unfeasibly loud, and no, it can’t create a black hole that big. At 1100 db it creates a 5 kg black hole with the same volume as a neutron.

## What will happen if we create 1100 dB sound?

Apparently, a sound of 1,100 decibels would create so much energy, it would act as a immensely high quantity of mass. This would, in turn, create enough gravity to form an extremely large black hole! Larger, in fact, than our observable universe.
