Unsolved mysteries of science. Damn questions of modern science
Incredible Facts
This project was launched two years ago, when several hundred scientists were interviewed, who were asked one question: what do you consider the greatest secret of nature and science?
Here's what they said.
What drives evolution?
You have probably heard the answer to this question: natural selection is accepted by scientists as the main engine of the vital functions of organisms and their very functioning. This is one of the most well-tested theories in science. But evolution through natural selection is the only explanation for the complexity of organisms?
"I believe that one of the great mysteries of biology today is whether natural selection is the only explanation for the process of evolution, and therefore the only way to generate the complexity of organisms, or are there other properties of matter that also play important role", - says Massimo Pigliucci (Massimo Pigliucci), specialist in the Department of Ecology and Evolution at Stony Brook University in New York (Stony Brook University).
What happens inside an earthquake?
In fact, it is very strange that we do not know the processes that are taking place on our planet right under our feet. Experts can tell you exactly where an earthquake is, what type of earthquake it is, and how long the tremors will last. But they are completely unsure of what is happening inside the planet during this natural disaster. The character and nature of the forces involved in this process is not yet completely clear.
"The issue of plate displacement during earthquakes is not yet fully understood and is one of the fundamental problems in all of earth science," says geophysicist Tom Heaton (Tom Heaton). "To this day, the nature of earthquakes remains a great mystery to physicists around the world."
Who you are?
The nature of consciousness has long puzzled psychologists and cognitive scientists. Part of the answer to this question, however, is surprisingly simple: most of our actions depend on the functioning of neural circuits. This opinion is shared by Joseph LeDoux, a neurologist at New York University.
"The intuitive idea that things are banal, like 'I'm in control of my behavior' is just as wrong as the idea that the Earth is flat," explains LeDoux. While we often think of ourselves as independent beings, this is actually not the case. Everything we do is influenced by unconscious environmental processes.
How did life appear on Earth?
The earliest evidence of microbial life on Earth dates back to 3 billion years ago. How it came about, no one knows. Ideas vary from development chemical reactions that occurred on the seabed before the occurrence of the corresponding reactions in rock formations.
"There are many theories about the origin of life on Earth, but since none of them can be either confirmed or disproved, there is no officially accepted theory," summed up the biologist Diana Northup (Diana Northup).
How does our brain work?
Of course, today we know much more about the activity of the brain than a few decades ago. But still, billions of neurons, each with thousands of connections, is a very complex topic. "We all think we understand the brain, at least our own, through experience. But our own subjective experience serves us very poorly in matters of how our brain works," said Scott Huettel (Scott Huettel), specialist Center for Cognitive Neuroscience at Duke University.
"We still don't have good way studying how groups of neurons form functional networks when we learn, remember something or do something else, including watching movies, listening to music, etc.," says University of California neurologist Norman Weinberger. " If we fully understand our brain, we can understand both its potential and its limits for thinking, emotions, reasoning, love and everything else.
Where is the rest of the universe?
"I call it dark side Universe," says University of Chicago cosmologist Michael Turner, referring to the great mysteries of dark matter and dark energy.
In fact, only 4 percent of the matter and energy in the universe has been discovered. The remaining 96 percent remain elusive, but scientists continue to search in the most remote corners and in deepest bowels Lands in order to solve two dark riddles.
Why does gravity exist?
You might think that this concept has long been understood, because Newton explained it many years ago. But in reality, everything is much more complicated. Gravity is the most poorly understood force in the universe, and it cannot be explained using the standard laws of physics.
Theorists believe it's all about tiny, massless particles called gravitons, which are the brainchild of gravitational fields. "Gravity is completely different from other forces that are described in a standard way, because when you do some small calculations of gravitational interactions, you get stupid answers, because the math just doesn't work in this case," says theoretical physicist Mark Jackson (Mark Jackson).
Is there a "theory of everything"?
There is a good "standard model" in physics that divides the universe as we know it into particles in order to describe every detail, from magnetism to what atoms are made of and how they stay in a stable state. The Standard Model considers particles to be small points that perform certain functions, some of which carry certain forces.
But the standard model has two serious shortcomings: it does not explain the process of gravity, and all the information loses its relevance when we are talking O high levels energy.
If, after all, a theory can be developed (many scientists say it will never happen) that explains gravity and can withstand the incredible energy forces of the early universe, then a universal theory of physics will become a reality.
Does alien life exist?
Life is everywhere, at least on this planet. Therefore, it is logical to assume that it exists in the entire universe. But so far we've only been able to scrutinize one world.
We know that solar systems like ours exist beyond. "We are here, made of stardust. So it's likely that there are other forms of life in the universe," says Jill Tarter, director of the Space Research Center in California.
Moreover, it is very likely that life forms that are outside our planet are very smart. "Humanity has made scientific and technological progress in just the last 200 years of the approximately 4.5 billion years of life on Earth," said Frank Wilczek, a physicist at the Massachusetts Institute of Technology who received nobel prize. "Therefore, it is likely that there are many scientific and technological civilizations that have existed and developed for many millions or even billions of years."
How did the universe begin?
This question is perhaps the most exciting. Simply put, all other secrets lie below this question, because it is paramount. Yes, the theory says it all started with the Big Bang 13.7 billion years ago. In the blink of an eye, the explosion grew to cosmic proportions. The idea, it would seem, is not bad, but there is only one bad thing: this statement cannot be believed in any way.
"The big bang theory is an extremely powerful idea, but it's still unclear what caused the explosion," says Eric Agol, an astrophysicist at the University of Washington.
There are so many in the world unsolved mysteries and secrets that even get a little uncomfortable! Someone is constantly trying to comprehend these secrets of the higher worlds, but once again fails. Ciphers, coded messages, mysterious signs on the margins, cryptograms, and so on - all this intrigues not only scientists, but also ordinary people. Each of us at least once in our lives, but think about one of the many mysteries of our universe. Or maybe someone else has yet to figure it out?
Secrets are all around us.
How many films have been made and books written about how to unravel these mysteries, but all these films are just fiction. In fact, neither the world-famous manuscripts nor the complex messages to descendants from their ancestors were ever completely unraveled.
Mystery of Voynich
It was not possible to unravel the unknown language in which the manuscript was written. In 1912, Wilfrid Voynich, a dealer in antique books, purchased a very strange book. All of its 240 pages contained completely new letters and numbers (if they were exactly these signs at all). In the book, in addition to words in an incomprehensible language, there were also diagrams, illustrations that demonstrated incomprehensible events, and also depicted unthinkable plants. Mystery? Also what! It was not possible to establish who the author of the manuscript was. But scientists were able to determine the time period in which the book was created - 1404-1438.
Manuscript "The Secret of Voynich" Whoever did not try to unravel the handwritten manuscript, and all in vain. But it does not seem that the author of the text simply decided to mock his descendants and drew scribbles in order to mislead everyone. Today there are a large number of theories in which the great scientists of the world are trying to solve the mystery of the book. Some think that this is a manual on alchemy, others are a pharmacopoeia, and still others generally see the intervention of other worlds in the creation of the manuscript and assign the book the status of an extraterrestrial manuscript. But whoever the author of the manuscript was, he definitely did not regret his personal time, effort and money for its creation!
Secrets of the higher worlds! Difficult to understand, encrypted and not fully solved the riddle on the sculpture located near the CIA in the USA - this is the sensational Kryptos! The sculpture was created by the master Sanborn and the four encryptions on its surface have not been completely unraveled (despite such a “neighborhood” with the CIA). The scientists managed to solve the first three riddles, but with the last one (despite the artist’s hints that the answer to it is encrypted in the first cipher), they are still tormented. In 2010, the most persistent researchers were still able to unravel one word in the code - Berlin, but what other words are nearby is still unknown.
Bail Treasure Search
Thomas Bale at the beginning of the 19th century was able to extract the treasure in the process of developing gold deposits in Colorado. It is not known what motivated this man, but the location of real wealth from a large number precious metals and stones he decided to encrypt. For this he used a set consisting of three ciphers. Of these, only the second was decoded, and the American Declaration of Independence became the key to it. This code indicated the area where the treasure is located, but the exact location of the cache is still unknown. Many seekers of adventure and mysterious treasures still hunt for untold wealth to this day.
How to find the Holy Grail?
In the UK, there is the famous Shepherd's Monument, created in the 18th century in Staffordshire. Many think that this is a message from the ancients to our contemporaries regarding the place where the Holy Grail is kept. The letters of the code have a certain sequence, only no one can decipher it. The author of the cipher is unknown, and this is another mystery of the surrounding world. Scientists suggest that in this way the secret of finding the Grail was encrypted by the Templars. Many celebrities have tried to decode this code, including Charles Dickens and Darwin.
Writing system or Rongorongo
On Easter Island, mysterious signs were found, depicted on artifacts and called Rongorongo. Scientists believe that these may be writing systems invented by different branches of mankind. It has not yet been possible to decipher the secrets of the ancient words, but there is an opinion that the encryption contains some information about the civilization that built the statues on this island.
Message from space
In 1977, as part of a program to search for signals from extraterrestrial intelligence, Jerry Eman recorded an incomprehensible signal, and it really did not come from Earth. Only 72 seconds continued human communication with an extraterrestrial civilization, which was supposedly located in the constellation Sagittarius, which is 120 light years away from our planet. On his transcript, the young man wrote the word "Wow", as an expression of delight about communicating with aliens. Perhaps the younger generation uses this word for a reason, but at the suggestion of other worlds!
Secrets of the Phaistos Disc
This is the most difficult riddle that would be beyond the power of Indiana Jones himself if he actually existed, and not just on the TV screen. The disk was found at the beginning of the last century by an archaeologist from Italy named Luigi Pernier. There are some strange symbols on this disc. One can see their similarity with the hieroglyphs of the ancient Chinese written languages. Secrets are supposed to ancient world are contained in this message, because it is at least three thousand years old, it was made in the second millennium BC. The Phaistos disc is the most important of all the mysteries of archeology.
Mysterious underwater world
Secrets underwater world interesting to scientists and ordinary people on all continents. Learn about the ancient civilizations that lived before the Flood, uncover the secrets of the sunken Atlantis and solve other most challenging tasks related to the Hydrocosmos - this is important for understanding our history. And if earlier they devoted a lot of time to the study of the underwater world, now they have switched to more for space exploration. But in the depths there are also many secrets that have not yet been comprehended!
Who are the NZOs?
Incomprehensible noises are recorded using modern acoustic devices (hydrophones). For the first time they were used by the American military services to track the movement of enemy submarines - the USSR. With the help of instruments, it was possible to listen not only to the songs of whales, but also to something more interesting. The secrets of the underwater world were not fully revealed to scientists from this, but they concluded that someone in the ocean was sending purposeful conscious signals. was named NSO - unidentified sound object. And who emits these signals to this day has not been established. Maybe these are the messengers of the ancient world, aliens, sea monsters or someone else?
"Quakers" of the oceans
Great scientists tried to answer the question of who makes interesting sounds “kva-kva” under water. Maybe it's a huge sea frog? Doubtful! It all started with the interest in this phenomenon of sailors who served on submarines. With the help of hydroacoustic devices, they picked up incomprehensible signals and called them Quakers. This name is even mentioned in the official documentation.
The sound came from objects that circled around the boats. This is exactly what was established thanks to direction finding. Incomprehensible creatures that could not be detected, as if they were trying to establish contact with the submarines, because they willingly responded to the signals of the submarine itself. And there was no aggression from the Quakers. The submarine was accompanied by creatures to a specific area and then they left it, saying goodbye to their usual “qua-qua”. What it was is still a mystery. So far, scientists have stopped working on it (or do it unnoticed by large masses of people so as not to sow panic), but the sounds have not disappeared and still inspire fear in sailors.
This anomalous zone does not reveal the secrets of the underwater world one iota, but only confuses researchers even more. Complex calculations, great research - and the mystery has not been solved. Since 1492, this place has been considered at least strange and frightening. The glow of water and sky, flames, a furious compass needle - all this is noted in the notes of the expedition of Columbus himself. In 1840, the place, located near Bermuda, was given the unofficial name of the triangle. In this area, a self-moving vessel was then found, which was completely without a team. What happened to the crew and thousands of other people who disappeared in the area after a strange find, is unknown to modern science.
In this place, not only ships, but also aircraft disappeared and disappear. And to find at least some wreckage and remains has not yet succeeded even once. But scientists studying the seabed in the Bermuda region stumbled upon a huge pyramid, several times larger than the famous pyramid of Cheops. The walls of this structure are absolutely smooth - there is no plaque, no shells or algae on them, and they are made of a material that resembles glass ceramics. The secrets of the underwater world, even with this discovery, have not been fully explored. The ocean is still a mystery to us, which interested ancient scientists and our contemporaries. Many studies of great scientists are classified. But sooner or later, everything secret becomes clear, so let's wait!
Atlantis is out of sight
The world only after millennia learned that there was another continent. And it will take the same amount of time to search for and study it. The secrets of the underwater world are revealed only to the persistent! Among the representatives of the ancient world, Aristotle mentioned Atlantis. But words are words, but evidence of the existence of the continent in the form of the remains of civilization has not yet been found. They say that the Atlanteans did not die all and founded their city in Tibet. And Mount Kailash is nothing but one of the pyramids built by these giants. But where they lived before and what actually happened to their homeland is known only from myths. Whether to believe them or not is up to you!
The secrets of the ancient world, the depths of the sea, one generation to another - this has always aroused and is of interest to people. Great scientists have not yet been able to solve a lot of mysteries. Suddenly it is you who can do it, write in the comments!
Science has already opened many doors for mankind, providing millions of important answers. But today there are still secrets, the key to understanding which, it would seem, is about to be found. But so far he's gone. The popular science resource tried to figure out how the TOP 10 undisclosed, but very interesting secrets. Participation in the compilation of the list was taken by both eminent scientists and ordinary people who had heard a lot about the issues facing science. So, the ten main secrets are ...
10. What factor governs evolution?
On the one hand, this question was answered long ago by stating: natural selection. This is one of the most popular theories. Note - theories, not axioms. Many experts tend to believe that everything is not so simple, and evolution cannot do without this factor alone.
“I think one of the biggest mysteries in biology today is whether natural selection is really the only determining process responsible for generating the complexity of organisms, or are there other factors that also play a role. I suspect that the latter option will be correct, ”says Massimo Pigliucci, a specialist in the department of ecology and evolution at Stony Brook University in New York.
9. What happens in the "heart" of an earthquake?
A lot is known about earthquakes: thousands of graphs of seismological activity have been compiled different regions Earth. And, it would seem, there is no place for this issue in the list. However, the accumulated knowledge cannot be called complete. Scientists can predict what territory the cataclysm will hit, how long it will last, how significant its consequences will be ... But seismologists are not able to accurately explain what happens during an earthquake inside the planet. "The problem of frictional sliding in earthquakes is one of the fundamental problems in earth science," says geophysicist Tom Heaton. And he adds that scientists have been painstakingly working for the past 30 years, trying to understand the basic "physics" of earthquakes.
8. Who are you?
The nature of consciousness fascinates psychologists and philosophers as well as other scientists. Part of the answer is already there, and it is surprisingly simple: most of our impulses to this or that action are "written" in neural connections, to which conscious thought does not always have access. And is it needed? Be that as it may, the unexplored areas today largely include not only the unconscious, but also quite conscious decisions: how are they formed? Where do they come from? Well, all that...
The idea that the mind completely controls behavior is just as wrong as the idea that the Earth is flat, scientists say. And although it seems to us that we are in charge of ourselves, this is due to a lack of knowledge about subconscious motives.
7. How did life appear on Earth?
On the one hand, you can talk about this topic for hours and never repeat it. On the other hand… Theories, theories. No one can really say how microbial life appeared on the planet billions of years ago. The range of assumptions is wide: from chemical reactions in water to reactions in stones.
“Many theories have been proposed, but since they are very difficult to confirm or disprove, in fact, not one of them has been fully approved,” explains Diana Northup, a biologist at the University of New Mexico, who explains what the catch is.
6. How does the brain work?
Some might say that this question was undeservedly placed on the list of mysterious, because a lot is known about the brain. Fact. Much is known. But if we compare what we know with what we have no idea about, then, as they say, it becomes excruciatingly painful. Billions of neurons, each of which has thousands of connections ... Scientists, however, say that. Well, let's wait and see.
“We all think we understand the brain. At least your own: through experience. But our subjective experience is a very poor guide to how the brain actually works,” says Scott Huettel of the Center for Cognitive Neuroscience at Duke University.
5. Where is the rest of the universe?
Imagine that from a huge cake you have only a crumb. Somewhere, this is how scientists feel when they study the secrets of the universe. Today, cosmologists are said to have located 4% of the matter and energy in existence. The remaining 96% is the missing cake in some way ...
“I call it the dark side of the universe,” cosmologist Michael Turner of the University of Chicago shares his thoughts on dark matter and energy. In short, a mystery with many unknowns.
4. Where does gravity come from?
Wait, it's like Newton said a long time ago that... Yes, he did say a lot of the right things, but that doesn't make the mystery of gravity any less interesting.
Gravity is one of the least understood forces that act on us. “Gravity is completely different from other forces described by standard models,” says Mark Jackson, a theoretical physicist at the Fermi Laboratory in Illinois.
- When you try to calculate any minor gravitational relationships, the result is a stupid answer. The math just doesn't work." Some theorists tend to suggest that the answer lies in tiny, weightless particles, gravitons, that "radiate" gravitational fields. However, this is not even an answer, but only the beginning of the answer.
3. Are there overarching theories?
Physicists have a "standard model" that "decomposes" the known part of the universe into particles and explains most of the phenomena. But this model is powerless when it comes to gravity, and confused when applied to high energy. Whether it is possible to derive a theory "for all occasions" is still unknown. Some scientists believe that this will never happen.
2. Is there extraterrestrial life?
If life is possible on Earth, why shouldn't it be possible on other planets as well? The answer "yes" seems much more logical than the categorical "no".
“Here we are, descended from stardust. So at the very least, it's just possible that there are others out there," says Fox Mulder... oh, sorry, Jill Tarter: head of a research center in California.
“Humanity has reached the level of scientific and technological civilization in just the last 200 years of those 4.5 billion that life exists on the planet. So we can well expect that somewhere there are many scientific and technological civilizations that have had millions, or even billions of years to develop, ”agrees Nobel laureate Frank Wilczek with a colleague.
1. How was the Universe born?
This question topped the list of the most mysterious. Well, it's only natural "All other mysteries stem from this one," says writer and astronomer Carl Sagan's widow Ann Druyan.
Based on the generally accepted point of view, everything happened after that thundered almost 14 billion years ago. And it all started with a size smaller than the dot at the end of this sentence. But in the blink of an eye, the scales increased significantly (oh, how significantly!) ... It is “an incredibly powerful theory, but we still have no idea what led to the“ swelling ”- explains Eric Agol, an astrophysicist from the University of Washington at the University of Washington. .
Well, here it is - the top ten secrets of the universe according to experts and readers of LiveScience. Are all worthy riddles on this list, do you think?
Guys, we put our soul into the site. Thanks for that
for discovering this beauty. Thanks for the inspiration and goosebumps.

It would seem that our world has been studied far and wide, and science will certainly have an answer to any question that interests us. However, no matter how. Until now, there are many mysterious things and phenomena that have no rational explanation.
site collected for you 10 questions that scientists are not able to answer.
cat purr
Everyone knows that cats always purr when they feel good. However, no one knows how they do it. There is no special organ in the throat of cats to make such sounds. It is interesting that during the purring it is impossible to listen to the heart or lungs of cats, and the purring itself is continuous, on inhalation and exhalation.
Scientists believe that cats use their vocal cords to make vibrating sounds that we hear as purrs. Also, in the course of research, it turned out that the frequency of purring is in the range necessary to accelerate regeneration and wound healing. Therefore, your cat is probably an excellent doctor.
Appearance of views out of nowhere
Scientists have been struggling with this riddle for many years. The fact is that many species of animals and plants on our planet simply appeared out of nowhere. They had no ancestors from which they could evolve, and this baffles science.
So it was, for example, with amphibians: the stage at which the fish gave birth to amphibians is not exactly known. And the very first land animals appeared already with developed limbs and a well-defined head. And dozens of various kinds. Then, after the alleged cataclysm (about 65 million years ago), which led to the extinction of dinosaurs, several various groups mammals.
Magnetic compass in cows
You probably didn't even think about it. In general, no one thought before the advent of Google Earth. It was this service that allowed us to study thousands of pictures of grazing cows (don't ask why) and discover one strange pattern. About 70% of cows, when eating or drinking, turn their heads due north or south. Moreover, this is observed on all continents, regardless of the terrain, weather and other factors.
What is dark matter made of?
About 27% of the entire universe is dark matter. This is such a thing that does not emit electromagnetic radiation and does not directly interact with it. That is, dark matter does not emit light at all. This property makes it impossible to directly observe it.
The first theories about dark matter appeared about 60 years ago, but scientists still cannot provide direct evidence of its existence, although everything indicates that it is.
How many planets are in our solar system?
Since scientists officially excluded Pluto from the club of planets, it is believed that there are 8 of them left in our solar system. But no matter how. Most of our solar system has not yet been explored. The region between Mercury and the Sun is too bright, and the region beyond Uranus is too dark.
By the way, right in the outskirts of our solar system, beyond Pluto, is the so-called Kuiper belt, which consists of icy objects. There, scientists discover hundreds of thousands of objects every day, the size of Pluto, and even more.
By the way, they noticed a big gap in the Kuiper Belt. This suggests that there is another planet the size of Earth or Mars, which has attracted all these stones around. So scientists will have to rewrite textbooks many times to explain how many planets there are in our solar system.
Why are people divided into left-handers and right-handers?
Scientists have studied well why most people use right hand more often than the left. However, they still cannot understand what mechanisms work in this case.
It is believed that the majority (from 70 to 95%) are right-handed, a minority (from 5 to 30%) are left-handed. And there is also a percentage of ambidexters in which both hands are equally developed. Although scientists disagree here.
It has been proven that left-handedness and right-handedness are influenced by genes, but the exact “left-handed gene” has not yet been identified. There is also evidence that environment can also influence dominant hand selection. So, for example, teachers retrained children to use their right hand more often than their left hand.
Extinction of the megafauna
The common name for giant animals that once walked the Earth is megafauna. Megafauna disappeared about 10 thousand years ago. And scientists haven't been able to figure out why.
Some believe that the megafauna became extinct due to climate change, but there is little hard evidence for this. Another theory is that they simply did not have enough food. However, everything is not so simple here either. Scientists in Alaska sometimes find perfectly preserved ones, in the stomachs and even in the mouths of which undigested greens were found. This suggests that the animals died literally for dining table, and all at the same time. Why this happened, scientists do not know.
Why do we dream
Some people believe that dreams are just random images and brain impulses, while others believe that they are deep meaning, these are subconscious desires, problems and experiences. But one way or another, no one will give you an exact answer.
Incredible Facts
These mysteries still raise questions from scientists and researchers.
1. Holes in the ground on Yamal in Siberia
In July 2015, a 100-meter crater appeared on the Yamal Peninsula in Siberia. Despite the fact that a team of researchers was sent there in November 2015, the reason remained unknown. Since then, two more craters have opened in the Tazovsky district and on the Taimyr Peninsula.
There is an assumption that the formation of dips in the ground is associated with a gas explosion or an eruption from within the permafrost.
2. Walrus at St. Pancras
The walrus at St. Pancras was discovered by archaeologists in the old church of St. Pancras in 2003. This site was used for a mass grave due to a series of epidemics in the early 19th century.
One of the graves contained the remains of eight people, along with the bones of a Pacific walrus.
Scientists have not been able to find an explanation for how the remains of the walrus got there.
3. D. B. Cooper
In 1971, a man known only by the name D.B. Cooper boarded a Boeing 727-100 at Portland International Airport. The flight, which took place on Thanksgiving Day, was bound for Seattle. During the flight, Cooper gave the flight attendant a note saying he had a bomb, demanding $200,000 and four parachutes.
The flight was delayed by two hours to give the FBI time to collect the ransom and parachutes.
The plane landed at Seattle-Tacoma Airport, and once all of Cooper's demands were met, the passengers were released except for one flight attendant. Cooper ordered the pilots to take off again and head for Mexico City. On the way, he jumped out and disappeared.
4. Invasion of the Air by Max Headroom
During the airing of an episode of the television series "Doctor Who", the signal of the television station was interrupted and a man in the mask of Max Headroom appeared on the screen, who made inarticulate sounds.
The reason for this and the identity of the masked man remains unknown, although there are several theories.
The shutdown lasted just over 90 seconds and occurred on November 22, 1987, which some attribute to the assassination of President John F. Kennedy on the same day in 1963.
Earlier that day in 1987, the same person silently interrupted a news program on another television channel.
5 Meat Rain in Kentucky
In the spring of 1876, in Bath County, Kentucky, pieces of meat fell from the sky within minutes, as reported in several major media outlets. According to some eyewitnesses of the event, the meat tasted like lamb.
There is speculation that the phenomenon is related to nostoc, a type of cyanobacteria present in the ground that swell into a jelly mass when it rains.
6. The Man in the Iron Mask
You may have heard about this story in the book and movies, however historical truth about this person may seem even stranger.
For more than three centuries, people are still trying to figure out the identity of a man who was mysteriously imprisoned and forced to wear a mask to hide his identity.
7 Hinterkaifeck Farm Incident
This incident has it all. distinctive features horror films: a strange house in the village, complaints about ghosts, the sound of footsteps in the attic and, finally, the brutal murder of an entire family by an unknown person.
This crime remains one of the most mysterious in the history of Germany.
8. Real night hunter
The unidentified serial killer, also known as the "Golden State Killer" and "Rapist from the East," committed a string of crimes in Sacramento County over the course of a decade, including robbing more than 120 homes, raping 45 people, and killing 12.
It is known that he called the victims in advance, and sometimes after, mocking them.
It is believed that the perpetrator of these crimes is still alive, and the FBI recently launched a campaign in the hope of finding a man who managed to avoid justice for so long.
9. Hum
We really appreciate the silence when it disappears, especially when it comes to some incomprehensible sounds.
A hum is a constant, low frequency noise that people hear in different parts light from the UK to New Zealand. At the same time, the source of the sound cannot be explained.
10. Ship "Mary Celeste"
The Mary Celeste is one of the most famous examples of ghost ships, a ship with a crew that disappeared under mysterious circumstances.
The ship was found abandoned off the coast of Portugal, leading to much speculation as to what happened to her crew.
11. Signal "Wow!" 1977
Signal "Wow!" is a radio signal that got its name from astronomer Jerry Eyman, who discovered it by writing "Wow!" on its printout.
The unexplained radio signal is believed to indicate the existence of extraterrestrial beings. Despite many attempts, the signal was never received again.
12. Tarrare
Tarrare was an 18th-century Frenchman famous for his strange eating habits and voracious appetite.
During the performances, he ate stones, live animals and a whole basket of apples, but he never satisfied his appetite. Despite his gluttony, he was of average weight.
13. Silent twins
Twins June and Jennifer Gibbons were born in Wales in the 60s and did not communicate with other people, talking only to each other and sometimes in a way that was not clear to everyone else.
The story got even weirder when the twins grew up and ended up in mental asylum. They had an agreement that if one of them died, the other should start talking to the rest of the people. Jennifer soon died suddenly from acute myocarditis, but doctors could not detect any signs of poison or drugs in her system, and her death remains a mystery.
After her death, June, as agreed, began to communicate with others.
14. Tunguska meteorite
On June 30, 1908, there was a major explosion in the Podkamennaya Tunguska area. The nearest city was 60 km away, but still felt the effects. The explosion produced 85 times more energy than atomic bomb, dropped on Hiroshima, and leveled about 80 million trees.
Although the destruction is believed to have been the result of a meteorite impact, no impact crater has been found, leading to many hypotheses.
15. Cicada 3301
Every year since 2012, a secret organization puzzles the Internet by anonymously publishing complex puzzles online. Whether this is some kind of tactic of the secret services or hackers, or the tricks of some kind of cult, is still not known.
16. Green Children of Woolpit
This event took place in 12th century England when two green-skinned children visited the village of Woolpit. They spoke a strange language and claimed to have come from the underworld where other green people live.
17. Voynich Manuscript
The Voynich Manuscript is a manuscript written in an unknown language with an unknown alphabet, containing diagrams and drawings, dating from around the 15th century. Researchers have been trying to decipher the strange book for centuries, but they have never been able to do it.
18. Case of Taman Shud
The Taman Shud case involves the discovery of a dead man on the coast of Australia. He did not have a passport and could not be identified. An autopsy showed that he had been poisoned, but there were no traces of poison.
The case became even more confusing when, 4 months after death, an expert examined the body of a man. In his pocket he found a small piece of paper with the inscription "Taman Shud".
These were the last words in the collection of poems "Rubaiyat" by Omar Khayyam, which translates as "completed". A piece of paper was torn from a book that was in a car near the beach. The book contained the nurse's phone numbers and a coded message that the police could not decipher.
The nurse said she had given the book to a man named Albert Boxall. Some time later, however, Boxall reappeared alive and had the same book with the last words.
19. Disappearance of Malaysia Airlines Flight 370
One of the unsolved mysteries remains Malaysia Airlines Flight 370, which disappeared on March 8, 2014. There were 277 passengers and 12 crew members on board the international flight from Malaysia to Beijing. The last contact with ground services was made less than an hour after takeoff, and the plane itself disappeared from the radar screens a few minutes later.
Military radar followed the plane for an hour after the incident, watching it veer off course until it disappeared into the Andaman Sea.
No distress calls, bad weather warnings, or reports of technical problems. The plane is believed to have crashed in the Indian Ocean, but the wreckage has never been found. Disappearance theories range from black holes to alien abductions.

The Zodiac is one of the most famous unsolved murders in history. In 1969, he killed at least five people in San Francisco.
