Will the meteor make a sound?Astronomers say yes, they will speak out

How big is the chance? Intersection Emma Zulaiha Zulkifl took this amazing photo in Sabah, Borneo, Malaysia. On December 15, 2018, she just captured a bright meteor in front of the bright Venus. She wrote: "Yes, the meteor is indeed scratched in front of Venus! Only some contrast and noise reduction adjustment in Photoshop CC2018." Good work, Emma! Some people claim to hear the sound of meteors. Is this possible? Looking down.

Listen, the sound of meteor?

The moment of meeting meteors is not only fun, but also in awe of us. The fleeting Taoist reminds us that there are many small rocks and even slightly smaller ice kernels every moment -almost no size can exceed sand particles, and they are entering the earth's atmosphere. As early as the surface of the earth, most of them were burned on the atmosphere. Seeing meteors is a interesting thing, but can they be heard?

It seems that astronomers do think so.

Hearing VLF radio waves?

Over the years, professional astronomers have not considered the idea of ​​the sound of meteor sounds. Why? Generally, meteors are burning at about 60 miles (100 kilometers) on the surface. The sound of sound is much slower than light. In a few minutes after observing a particularly large meteor, we should not be able to hear its bombardment. It is like thunder after the flash has happened. A 60 -mile meteor exploded about five minutes after appearing. This is a "sound wave" meteor. Its noise is related to the ultrasound explosion caused by supersonic aircraft.

Buw, sip, hissing

In 2013, "Life Science" reported a typical example of people hearing meteors. It happened in 817 AD, when a meteor shower passed through China. According to a report from the physicist of the University of Newcastle, Australia, a report from the physicist at the University of Newcastle, a report from the University of Newcastle, a report from the University of Newcastle. Similar incidents occurred in the UK in 1719.

Astronomer Edmond Halley Said:

Astronaut Edmond Hally said:

When the meteor passed, several accidents happened, and many of them were purely fantasy. For example, when they heard thesing sounds when moving forward, they surrounded them.

The negation of these observations believes that the perception of the sound may be the psychological role produced by "frightened imagination", which has made the research on this phenomenon backward for nearly two centuries.

A meteor in 1978 changed people's thoughts

It was not until the 1970s and after the 1970s that scientists began to take this report seriously. As Keay reported in the magazine "Small Star, Comet, Meteor", those who claimed to hear meteors were rejected as lunatic. But later, a large meteor in New South Wales caused hundreds of reports in a large meteor over New South Wales. Keay analyzed 36 of these reports.

VLF radio waves spread at the speed of light, so the observers will hear them while seeing the meteor spending over the head. But these waves require some physical things as converters and make sounds. Keay found that various objects, such as aluminum foil, character, pine needle and other plant leaves, fine wires, dry hair, and wire frame glasses can make that kind of sound. This phenomenon is called acoustic and electronics.

An example of an observer pulls these items together:

When I was watching Leo Meteor Shower in 1999, my head fell to the ground and heard the sound of the cricket. My head was close to the grass and then moved away, and I also wore metal frame glasses. The sound is obviously at the same time as the observed light appears at the same time.

Mongolian meteor

A team of scientists conducted a lot of experiments in Mongolia during the Leo Meteor Shower in 1998. They found a position very carefully. In the center of Mongolia, there was no life, no night activities of humans and animals, as well as the power cord and any type of AC electrical equipment. The grievances covered by snow are very cold, -17 Fahrenheit (-27 degrees Celsius). In addition to capturing the sound records from the two bright meteors, the observer also heard the sound of the meteor. This is their results and these results come from other studies.

The sound appears before the brightest moment

You can hear the sound before the fire meteor reaches the maximum brightness. The frequency of sound is 37 to 44 Hz. The sound audio that ordinary people can hear is 20 to 20,000 Hz, so the sound frequency of the meteor is close to the low -end of the range. You may have heard a 30hez voice, if you have drove the rear window to drive quickly on the highway.

How can you increase the probability of hearing the sound of meteors?

There are some suggestions here: sitting on a plastic waterproof cloth near the dried leaves, rolling your hair, wearing metal frame glasses, and a few sheets of aluminum foil and printing paper. Take a look at the discussion and comments here.

Not only did the meteor produce a low -frequency sound. Aurora, earthquakes and large rockets re -returned to the stage of electro -sound sounds.

Hearing more meteors you see?

Keay's assumptions were further tested on November 18, 1999. Researchers detected different VLF sounds, and found that many meteors could not even be seen by the eyes, but they could be heard. In fact, the number of meteors detected with VLF signals is only 50 times that of sight. Dennis Gallagher, a spatial physicist at the Marshall Space Flight Center in the United States, said: What makes this exciting is that we are talking about a phenomenon that has been experienced by people for thousands of years. Even people who heard such a sound were laughed at in modern reports. Only about 25 years ago, Keay can do research to make the experience of all generations look acceptable. It shows that there are still miracles in nature that has not been conscious and understanding. We should open our hearts for this meteor experience as a reason to open our hearts that are still waiting to be learned.

Interesting facts: When a meteor body — a small rock body like space and dust -burning in the atmosphere, they are called meteors. When a meteorite is large enough to survive when it can enter the atmosphere and hit the ground, it is called meteorite.

Dian language: Can you hear the sound of meteors and see them? Scientists are.
