What is the loudest thing in the world?
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away.
Why is 194 dB the loudest sound possible?
A sound of 194 dB has a pressure deviation of 101.325 kPa, which is ambient pressure at sea level and 0 degrees C. Thus, the sound waves are creating vacuums between themselves, and no higher amplitude is possible.
Is silence a sign of weakness?
“If one is silent during obvious situations of evil practices, this could be a clear sign of weakness or fear. If one is silent because they are a great listener, this is a simplified form of strength. Silence can be served by both the weak and the strongest of people.
How loud is a jet?
The sounds associated with jet planes measure between 120 and 140 decibels. Any sound above 85 decibels has the potential to cause hearing damage, especially with frequent or prolonged exposure. Wearing ear protection and limiting exposure to loud sounds is the best way to protect against noise-induced hearing loss.
Is silence better than Word?
Communication is so much more than words. Sometimes the most powerful thing a leader can say—is nothing. Silence has a habit of revealing meaning. A well-placed pause or an extended silence, especially after a powerful question, can communicate deeply.
Is silence considered rude?
Silence is not rude; rather, silence is a language of the wise that they prefer over the foolish tittle-tattle. These people understand the power of their words and use them carefully instead of speaking without thinking, resulting in breaking hearts and spreading lies.
Can a sound louder than 1100 dB black hole?
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 did the atomic bomb sound like?
“Almost no one in Hiroshima recalls hearing any noise of the bomb,” Hersey wrote at the time. It is jarring to hear. The boom is more like a shotgun than a thunderclap, and it’s followed by a sustained roar. Here’s one example, from a March 1953 test at Yucca Flat, the nuclear test site in the Nevada desert.
How loud is 1100 decibels?
1100 decibels is preposterous. 20 db is ten times as loud as 10 db. To the Human ear, it sounds about twice as loud. Our ears are well designed that way, we filter out loudness.
How many decibels is a nuke?
210 decibels
Where is the quietest room on earth?
In this room at Microsoft’s headquarters in Redmond, Washington, all sound from the outside world is locked out and any sound produced inside is stopped cold. It’s called an “anechoic” chamber, because it creates no echo at all — which makes the sound of clapping hands downright eerie.
Do stars make noise?
Like bubbles rising in a pot of boiling water, sound waves move through a star’s interior because of temperature changes. But unlike on these planetary bodies, stellar sound waves are generated continuously by turbulence in the near-surface layers of stars.
Is Indian flag on moon?
India is now the fourth nation to place a flag on the Moon after the Soviet Union, United States and Japan.
How noisy is space?
Although sound does not travel in the vacuum of space, the inside of the International Space Station (ISS) is quite noisy. There are many pumps and fans that allow people to live on the ISS. They control the station’s heat, humidity, and carbon dioxide levels.
What did the moon smell like?
Twelve people have walked on the Moon and all of them agree: the Moon smells like gunpowder. According to Space.com, astronaut Jack Schmitt said: “All I can say is that everyone’s instant impression of the smell was that of spent gunpowder, not that it was ‘metallic’ or ‘acrid’.
Can a star turn into a planet?
Yes, it is possible for stars to turn into planets. But this happens for only a specific category of stars- called as brown dwarfs. Brown dwarfs are often called failed stars. They are objects that are too compact in size to be stars, but too huge to be planets.
Who owns the moon?
The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised.
Why is space silent?
In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. ‘Outer space’ begins about 100 km above the Earth, where the shell of air around our planet disappears.
How dark is space?
Above the Earth’s atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn’t absolutely black. The universe has a suffused feeble glimmer from innumerable distant stars and galaxies. This artist’s illustration shows NASA’s New Horizons spacecraft in the outer solar system.
Is it possible for there to be nothing?
Therefore absolute nothingness is impossible. One moer point “nothingness” means “there not being anything (not something)”, and “be (being)” means “existence”, which according to your definition is an attribute – and an attribute can only be an attribute of something (anything).
Why do things exist rather than not exist at all?
Leibniz thought that the fact that there is something and not nothing requires an explanation. The explanation he gave was that God wanted to create a universe – the best one possible – which makes God the simple reason that there is something rather than nothing.
Is the flag still in the moon?
Due to the resolution of the LRO cameras, shadows from the fabric of the flag can be seen but the pole cannot, showing that the flags did not disintegrate entirely. A photo review of the Apollo 11 site shows that Aldrin’s observation that the flag fell over was likely correct, as no flag was seen in the images.
Is there noise on the moon?
NASA astronauts in orbit around the moon in 1969 heard a whistling sound described as “outer-spacy,” “weird,” and “eerie.” Apollo 11 astronaut Michael Collins, in a book published years later, said the noise was just interference between the lunar module and command module’s VHF radios, the Weather Network said.
Can you touch the moon?
Twelve people have walked on the moon since humans landed there 50 years ago, but no one has ever directly touched its surface. Touching lunar rocks inside a spacecraft, or in a museum, is one thing; removing a glove and exposing yourself to the vacuum of space is another.
Does sound exist in space?
Space is a vacuum — so it generally doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can’t hear them).
Where is the quietest place on Earth?
Minneapolis
Why do you not see stars in space?
In space, or on the moon, there’s no atmosphere to spread the light around, and the sky will appear black at midday – but that doesn’t mean it’s not just as bright. Even in space, stars are relatively dim, and simply don’t produce enough light to show up in photos set for bright sunlight.
Can you talk in space?
When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet. Sound travels in waves, and it moves at different speeds through air or water or other materials.
