Antarctica is often referred to as the Frozen Continent. Beneath the permafrost ice, there are many mysterious things hidden, where we are constantly making new discoveries. The scientists decided to conduct an experiment by throwing a piece of ice into a 90-meter-deep borehole. When the ice fell to the bottom, a very strange sound was made. What does this voice represent?
Antarctica is one of the largest lands in the world, and only scientists and researchers from all over the world live there. In order to study the ancient methods of self-purification of air and atmosphere, scientists dug a hole in the thick layer of ice and drilled a clean cylindrical cave at a depth of 140 meters on the surface with a special drill bit, some of which is as old as 800,000 years old, which is a good indicator of the past climate state, a bit like we determine the age of a tree by looking at the rings of trees, but its actual situation is much more complicated. After easily drilling out of the hole, the scientists decided to put some ice in the hole to see what would happen next, so they heard some very special sounds, which seemed to be on a space shuttle, crossing obstacles, accompanied by the sound of countless stones colliding with each other, so that the pitch changed with the rapid fall of the ice, from the high note all the way to the end of the heartbeat-like bass. Scientists were so confused when they first heard this sound that they threw more ice into it, only to find that the same type of sound was produced, but in a different way of discerning, and they didn't know what was underneath it, and more importantly, why it was made.
Antarctica has many volcanoes, many of which are hidden under super thick ice, and scientists have found 91 volcanoes and said there may be many more in real numbers, so Antarctica is likely to be the largest volcanic area in the world. As they were doing routine scientific research, they found many obvious giant cones underground, some 3 kilometers below the ice, some more than 914 meters and several 10 kilometers wide, but on the surface everything seemed as flat as a piece of paper, and they might have thrown the ice into a volcano on which they were standing, but it was unlikely. Although scientists stumbled upon the existence of an underground volcano, it is unlikely that they would actually stand on top of a volcano that carries their workstation, and they are more likely to work in an area that is easier to study ancient climates than elsewhere and safer.
They collected samples of ice and studied them in the lab, like exploring a piece of amber from the time when dinosaurs roamed the earth millions of years ago, except that now scientists are not studying small insects, but ancient dust, bubbles, sea salt, volcanic ash, and anything else that may have come from the environment, which simply show the climate conditions of that period, and these ice samples may indicate that the ice in western Antarctica melted during a certain period of time in the past, if so. Then this is likely to happen again. That is, if it happens, sea levels will rise and affect coastal cities and remote islets, but despite the evidence, scientists are less certain that this is the case. Depending on the discovery, the process of studying the ice sample may take a week, or even a year, scientists little by little or crush, or melt the sample for analysis, just like the rings of the tree, the deeper the more you can see the more ancient state, in order to study the ancient bubbles trapped in the ice, researchers have to compress the sample under the vacuum cover to prevent air from entering, while extracting the air from the bubble and putting it into a small bottle, the laboratory has a variety of instruments and equipment can study these ice samples However, because this sample is very easy to be destroyed, every measurement must be made in a clean room to avoid any damage. Scientists had to wear proper tights, wear layers of gloves and keep air circulating, and even something as trivial as a fingerprint could ruin a sample, and they looked for specific patterns to see how the sample changed in atmospheric composition and temperature.
But throwing a few pieces of ice into the hole isn't too bad, it makes this strange sound for the same reasons that it makes a difference from the sound of the car honking when driving and the honking when it is forbidden, in scientific terms, the Doppler reaction, that is, relative to an observer who moves relative to the wave source, this has a pronounced frequency change, this effect does not mean that the frequency of the sound has changed, it is just a change, this also applies to other types of waves, such as water waves and light waves, but the most common in the Doppler effect is the example of sound waves. So when the scientists threw the ice cube to the bottom of the hole, the sound waves traveled upwards and bounced back and forth around the narrow pipe of the hole they had drilled, so it made a popping sound, and the ice went all the way down 140 meters under our feet.
Oil tankers will dig holes thousands of meters deep in the crust of the seabed, and Russia's Kola ultra-deep drill is the deepest hole ever dug by humans, it expresses more than 12,200 meters deeply, and it takes nearly 20 years to reach 12 kilometers, drilling 12 kilometers down, but reaching the mantle. In 1992, engineers discovered that the temperature was 37 degrees Celsius higher than they had predicted, so they stopped drilling, and then the hole was abandoned, and now it is just a meaningless cave. This is the closest place we have excavated to the center of the Earth, and the terrible thing is that some of the staff at the scene said they heard sounds coming from inside.
In Yemen, Bahout, the heart of the country's eastern desert, has an ancient cave that is actually closer to Oman's capital, Shana. Unlike the holes in Russia and Antarctica, which have not been artificially drilled, or have been kept here for many years, and the locals have always stayed away from it as much as possible, they don't even like to talk about the hole, so they say it will bring bad luck to the people around them and even those who say its name. They claim that the hole was built for the sake of seeing the soul, but this is not very likely. The hole is 30 meters wide and 100 to 200 meters deep, and you can even hear strange noises coming from inside, but according to some scientists, the hole is almost empty, and there is almost no oxygen underneath, so it is really unlikely that there are people or any life there.
In March 2016, scientists captured certain muffled grunts in the Challenger Abyss of the Mariana Trench, some of which were accompanied by screams, and scientists spent weeks using some sort of too-encapsulated microphone to capture these sounds so that the enormous pressure at Earth's lowest point wouldn't crush the microphones most used for radio. During the radio, the scientists also had to slowly lower the microphone, because the pressure there was 1,000 times greater than the pressure at sea level. For a full 23 days, the microphone recorded the classic sounds of whales passing by, the sounds of ships passing overhead, and even the rumble of nearby earthquakes, but they couldn't be sure exactly what caused those initial grunts. The researchers couldn't understand whether the noise at the bottom of the Mariana Trench was caused by humans or naturally formed, and they also wondered whether the sounds would have an impact on marine life, such as dolphins and whales that rely on echolocation. They still haven't sorted out the doubts, but scientists estimate that the noise in the ocean is 10 times greater now than it was 50 years ago, and that with the development of shipping, submarine and underwater construction technology, the noise of the ocean will only get louder over time.
The Northern Lights are usually accompanied by sound, but no one has discussed this. Usually the sound can be heard when the aurora is at its strongest, and scientists have not wondered what caused the faint crackling and crackling sound that we can still hear even if it is far away, they used some special microphones, and found that the sound appeared 70 meters above our heads, which is quite low. They are caused by the electrical charges acquiring energy in specific areas of the laser, which are disturbed by the magnetic storm that causes the Northern Lights, so that some tiny sparks are released into the atmosphere, resulting in a faint crackling and crackling sound.
