Would black holes be loud?
Black Holes: Incredibly Loud and Extremely Distant.How loud can a black hole cause?
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!Is a black hole quiet?
Researchers from the European Southern Observatory say this black hole is unique, because it does not react violently with its environment: it is silent, practically invisible and the closest black hole to Earth. They detail their findings in a study published Wednesday in the journal Astronomy & Astrophysics.Can you hear a black hole?
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.How loud is a black hole in decibels?
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!A Black Hole's Magnetic Reversal
Can we create 1100 dB sound?
1100 dB is loud beyond any imagination and it is incincievable that any sound of this level could be produced on earth. However sound does not produce a black hole.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, at 0 degrees Celsius (32 Fahrenheit). Essentially, at 194 dB, the waves are creating a complete vacuum between themselves. You can go louder than 194 dB, but that's not technically a “sound” anymore.What is the deepest sound in the universe?
Sept. 9, 2003: Astronomers using NASA's Chandra X-ray Observatory have found, for the first time, sound waves from a supermassive black hole. The "note" is the deepest ever detected from any object in our Universe.What can escape a black hole?
Black holes are the blackest things in the universe. Because of their enormous, space-bending gravity, everything that falls into them is instantly ripped apart and lost. Scientists have never seen a black hole, because nothing, not even light, can escape them.What is the lowest sound in the universe?
They are 30,000 light-years across and have a period of oscillation of 10 million years. By comparison, the deepest, lowest notes that humans can hear have a period of about one-twentieth of a second. The black hole is playing ''the lowest note in the universe,'' said Dr.Are we rotating around a black hole?
Yes. All astronomical objects, including black holes, are formed by gravity pulling matter together. If a cosmic body originates from anything that had even the tiniest amount of rotational motion originally, then this spin rate will become greatly enhanced as the object collapses.Is the Milky Way rotating around a black hole?
So black holes cannot be the source of galaxy rotation: they are simply too small, and too far away from most of the galaxy to do it.Can a black hole spin at the speed of light?
For the first time, astronomers have managed to measure the rate of spin of a supermassive black hole—and it's been clocked at 84 percent of the speed of light, or the maximum allowed by the law of physics.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.What is the loudest sound ever made?
The loudest sound ever created by humans, not by natural causes, was said to be the atomic bomb blasts over Nagasaki and Hiroshima. Those clocked in at around 250 decibels. NASA's highest recorded decibel reading was 204 and that was the first stage of the Saturn V rocket.Is the sun really loud?
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.Is there a white hole?
The short answer, unfortunately, is no. White holes are really just something scientists have imagined — they could exist, but we've never seen one, or even seen clues that one may exist. For now, they are an idea. To put it simply, you can imagine a white hole as being a black hole in reverse.Does time stop in a black hole?
Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.Has anyone got lost in a black hole?
Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system.How cold is space?
According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).Is the universe silent?
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.How quiet is space?
Space isn't completely quiet — in fact, it's rather loud. Explore the anomalies that drown out all other noise. Sound doesn't travel in space. That's the knowledge most people have, however, it's not exactly true.How loud would a supernova be?
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.How loud is a nuclear bomb?
A nuclear bomb.Decibel meters set 250 feet away from test sites peaked at 210 decibels. The sound alone is enough to kill a human being, so if the bomb doesn't kill you, the noise will. Fun fact!
How loud is a blue whale?
Not only can baleen whales emit calls that travel farther than any other voice in the animal kingdom, these giants of the deep also create the loudest vocalisations of any creature on earth: the call of a blue whale can reach 180 decibels – as loud as a jet plane, a world record.
