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.

Can you create 1100 dB sound?

It is not possible for a sound to be 1100 decibels (dB) loud.

Can a 1100 dB 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.

What is the loudest sound in the universe?

1. The Tunguska Meteor: This was a huge explosion in Russia close the Tunguska River of Podkamennaya. It had the comparable effect of a 300-315 dB 1000-mega-ton bomb. This is often regarded as the loudest one-time event in history.

Is it Quiet in a black hole?

“The spiral shape of the magnetic field channels the gas into an orbit around the black hole,” said Darren Dowell, a scientist at NASA's Jet Propulsion Laboratory, principal investigator for the HAWC+ instrument, and lead author of the study. “This could explain why our black hole is quiet while others are active.”

What Actually Happens When You Drop Something into a Real Black Hole?

Is it hot inside a black hole?

Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius. Supermassive black holes are even colder.

Would a black hole be scary?

Once you're past the event horizon things would get really grim. If you were heading towards the centre of the black hole feet first, the gravitational pull on your feet would be a lot stronger than the gravitational pull on your head. You'd get stretched and squished like spaghetti.

Why is 194 dB the loudest sound possible?

At 194 dB, the energy in the sound waves starts distorting and they create a complete vacuum between themselves. The sound is no longer moving through the air, but is in fact pushing the air along with it, forming a pressurized wall of moving air.

How loud can a human yell?

Loud appliances such as a vacuum cleaner or power tools could exceed 80 dB. Human screams can be quite loud, possibly exceeding 100 dB (as of March 2019, the world record is 129 dB!) —but you probably want to avoid that because screams that loud can hurt your ears!

How many decibels is a nuke?

Nuclear bomb – Explosion

A nuclear bomb explosion has been reported to be 240 to 280 dB+. A sound level meter set 250 feet away from test sites peaked at 210 decibels. At the source, the level is reported to be from 240 to 280 dB+.

How many decibels is the sun?

But if we could hear the constant roar, it'd be pretty loud, even from here. One heliophysicist crunched the numbers and estimates the noise would be around 110 decibels, or about the same volume as speakers at a rock concert.

How loud is a supernova?

A supernova would sound like 10 octillion two-megaton nuclear bombs exploding. A supernova, however, just might be the most brutal concert in the universe.

What dB is too loud for humans?

Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears. The table below shows dB levels and how noise from everyday sources can affect your hearing.

What is the loudest dB ever recorded?

On the morning of August 27, 1883, a volcanic eruption began. The sound of the eruption, as the lave split the Earth and shot out of the volcano, is estimated to have reached 310 decibels (dB). The eruption took place on the Indonesian island of Krakatoa, and it caused half the island to collapse.

How many dB is a shotgun?

Understanding Decibel Levels

For comparison purposes, a shotgun produces 155 dB on average. Prolonged exposure to high decibel levels can come from everyday sounds. When we're continually exposed to these noises, hearing loss gradually happens.

What would 200 decibels do to you?

Sounds between 170-200 dB are so intense that they can cause lethal issues like pulmonary embolisms, pulmonary contusions, or even burst lungs. As for exploding heads, you can expect that from sounds above 240 dB. However, such high intensity sounds are very rare.

Is it illegal to scream really loud?

Speech, even when it is loud, offends or annoys others, is constitutionally protected. Additionally, there is legal precedent to establish that merely yelling or cursing does not substantiate a disorderly conduct charge.

Why is silence so loud?

The brain creates noise to fill the silence, and we hear this as tinnitus. Perhaps only someone with profound deafness can achieve this level of silence, so paradoxically loud.

How loud was Tsar Bomba?

4. The infamous Tzar Bomba reached probably 224 dB(Z) (releasing one fourth of the Krakatoa explosion), and accounts for the largest human-made noise. Some sources report that this event created a 280 dB(Z) level, but I don't think it can be a correct value.

Is spaghettification painful?

Either way, spaghettification leads to a painful conclusion. When the tidal forces exceed the elastic limits of your body, you'll snap apart at the weakest point, probably just above the hips.

Is space infinite?

We could think of the universe as a sphere expanding indefinitely and infinitely. Or it might curve and bend in ways that could make it a closed system (like a donut), where if you were to travel in a straight line for long enough, eventually you'd end up back where you started: space would be finite.

Why can't you leave a black hole?

Black holes are dark, dense regions in space where the pull of gravity is so strong that nothing can escape. Not even light can get out of these regions.
