What is the loudest thing ever?

The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.

What is the loudest noise possible?

Strictly speaking, the loudest possible sound in air, is 194 dB. The “loudness” of the sound is dictated by how large the amplitude of the waves is compared to ambient air pressure. 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).

How loud are black holes?

On how the black hole audio was made

And it was essentially a B-flat about 57 octaves below middle C. So we’ve taken that sound that the universe was singing and then just brought it back up into the range of human hearing — because we certainly can’t hear 57 octaves below middle C.

How loud can a human yell?

Common Sources of Noise and Decibel Levels
Everyday Sounds and Noises Average Sound Level (measured in decibels)
Shouting or barking in the ear 110
Standing beside or near sirens 120
Firecrackers 140–150

What is the loudest thing ever? – Related Questions

How loud is the sun?

The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth! The enormity of the sun’s surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.

Do black holes have sound?

The sound waves were discovered in 2003, when, after 53 hours of observation, researchers with NASA’s Chandra X-Ray Observatory “discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note.”

What are the loudest things on earth?

Know your decibels: 10 of the loudest sounds
  • 230 dB: Sperm whale.
  • 180 dB: Rocket launch.
  • 130dB: A plane taking off 100m away.
  • 120 dB: Fireworks.
  • 110 dB: Live music gig.
  • 100 dB: Night club.
  • 97 dB: Fire alarm.
  • 94 dB: Lawnmower.

How do you make a 1100 dB sound?

so to get 1100 dB, you need to explode 1*10^85 atomic bombs or 1 with 85 zeros on the right. Yes, that will create a blackhole.

Can you hear the sun?

Today, we can hear the Sun’s movement — all of its waves, loops and eruptions — with our own ears. This sound helps scientists study what can’t be observed with the naked eye.

What does the Sun smell like?

But the truth is that the sun itself doesn’t have a smell — or if it does, we can’t get a whiff of it. So what we’re left with is the “smell” of outside air. And that’s where the story gets interesting, because it turns out that air really does smell differently based on whether it’s a warm, sunny day or a cold one.

How old is the Sun?

4.603 billion years

Does space make noise?

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.

What does space smell like?

sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’. Some astronauts have likened the smells of space to walnuts.

How cold is space?

Space is very, very cold. The baseline temperature of outer space is 2.7 kelvins (opens in new tab) — minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius — meaning it is barely above absolute zero, the point at which molecular motion stops. But this temperature is not constant throughout the solar system.

Is the Sun moving?

Yes, the Sun does move in space. The Sun and the entire Solar System revolve around the center of our own Galaxy – the Milky Way.

Will the sun ever burn out?

Earth will be scolded and become bone-dry. In about 5.5 billion years the Sun will run out of hydrogen and begin expanding as it burns helium. It will swap from being a yellow giant to a red giant, expanding beyond the orbit of Mars and vaporizing Earth—including the atoms that make-up you.

How long will the Earth survive?

The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.

Why don’t we feel the Earth spinning?

But, for the most part, we don’t feel the Earth itself spinning because we are held close to the Earth’s surface by gravity and the constant speed of rotation. Our planet has been spinning for billions of years and will continue to spin for billions more.

What would happen if the Earth stopped spinning for 5 seconds?

Could we ever lose gravity?

The only thing we know that affects a body’s gravity is the amount of mass it contains. So to change Earth’s gravity we would need to add or remove mass from our planet. But to make a noticeable change, we would need to move vast amounts of material. Another factor is the rate at which our planet rotates.

How fast would Earth have to spin to throw us off?

Gravity and the centrifugal force of Earth’s spin keep us grounded. In order for us to feel weightless, the centrifugal force would need to be ramped up. At the equator, Earth would need to spin at 28,437 kilometres per hour for us to be lifted off into space.
