The world is full of mysteries and secrets. Some of them have been solved. But there are also some reasonable explanations that have not yet been found. Below is a list of ten unsolved mysteries peace.
D. B. Cooper is the alias of an unknown assailant who, on November 24, 1971, hijacked a Boeing 727 with 42 passengers on board, flying from Portland to Seattle. After receiving a $200,000 ransom, he released the passengers, forced the pilots to take off, and bailed out. Despite an extensive FBI investigation, it was never possible to obtain any information about the whereabouts of the criminal, his real name and further fate. Of the ransom received, only $5,800 was found on the banks of a river in Washington state.
There are several theories regarding the circumstances of the crime and future fate D. B. Cooper. The FBI believes Cooper died after the jump, but no physical evidence was found to support this theory. This terrorist attack remains the only unresolved case of air piracy in American aviation history.
The Taman Shud case is an unsolved murder case of an unknown man found dead on December 1, 1948 at Somerton Beach in Adelaide, Australia. There were no visible wounds on the deceased's body. In addition, the autopsy showed that he was completely healthy before his death. In the man's pockets they found a bus ticket, chewing gum, cigarettes, coins, matches and several other things. The biggest resonance was caused by a piece of paper found on him, torn from a copy of a very rare edition of Omar Khayyam, on which only two words were written - Tamam Shud (“Tamam Shud”). The investigation has still not been able to establish either the identity of the deceased or accurately determine the method of his death.
Atlantis
One of the unsolved mysteries of the world is considered to be “Atlantis” - a legendary island, perhaps a civilization (an archipelago or even a continent) whose existence and location are uncertain. The Lost City became known thanks to the mentions and comments of ancient Greek historians Herodotus, Posidonius, Strabo, Diodorus Siculus, Proclus. According to the records of the philosopher Plato, Atlantis was located to the west of the Pillars of Hercules, opposite the Atlantean Mountains, and was swallowed up by the sea in one day (probably by an earthquake or tsunami) around 9500 BC. e. However, most modern historians believe that Atlantis is a typical philosophical myth.
The Voynich Manuscript is a mysterious, undeciphered book written in the 15th century (1404–1438) by an unknown author in an unknown language using an unknown alphabet. The thickness of the book is 5 cm, it contains about 240 pages, measuring 16.2 by 23.5 cm. During its existence, the manuscript was intensively studied by many professional cryptographers, including those recognized throughout the world, and none of them managed to decipher a single word . There is a theory that this book is just a bunch of meaningless random symbols that have no meaning, but there are also those who believe that the manuscript is an encrypted message.
In sixth place in the ranking of unsolved mysteries of the world is the signal “Wow!” - a strong narrow-band space radio signal recorded by Dr. Jerry Eyman on August 15, 1977 while working on the Big Ear radio telescope at Ohio State University. The anomaly lasted 72 seconds and did not occur again. There are many versions explaining the origin of the signal. The most interesting of these is the theory that the signal was sent from an alien starship that was moving.
"Taos Rumble"
The "Taos Rumble" is an unsolved anomalous sound phenomena coming from the desert near the city of Taos, New Mexico, USA. The sound is similar to heavy equipment moving along a highway, although there are no major roads in the area of the town. It is interesting that only local residents hear it and very rarely visitors. Scientists who examined it were unable to find the source of the hum.
Similar phenomena have been known since the early 60s of the 20th century and have been observed almost all over the world, but most often it is heard in North America, Europe and Australia. Sometimes “noises” are accompanied by other sounds, hissing, whistling, etc. When listened to for a long time, they can cause headaches, dizziness, nausea, upset stomach and other unpleasant sensations.
The Loch Ness monster (Nessie) is a mysterious animal or group of animals supposedly living in the mysterious Scottish lake Loch Ness, the depth of which in some places reaches 250 meters. Numerous eyewitness accounts describe this mysterious creature as a 40-foot-long animal with four fins and a long neck with small tubercles, which appears from time to time on the surface of the lake. There are several theories explaining the nature of the supposed animal, one of them says that the Loch Ness monster is nothing more than a plesiosaur that has survived to this day. Today, scientists can neither confirm nor deny its existence.
Amelia Mary Earhart - American pilot, journalist and poet. The first female pilot to fly the Atlantic Ocean in 1932. In 1937, while attempting to fly around the world, Amelia went missing in the central Pacific Ocean near Howland Island. Despite an immediate search and rescue operation on which the US government spent approximately $4 million (the most expensive and extensive operation in the history of the US Navy), no trace of either the plane or the pilot was found. The search for the famous female pilot continues today, but the mystery of the disappearance of Amelia Earhart, her navigator and the plane remains unsolved.
Jack the Ripper is the nickname of an unknown serial killer (or killers) active in the Whitechapel area of London in the second half of 1888. His victims were prostitutes from poor neighborhoods, mostly middle-aged, whose throats were cut by the killer before opening the abdominal cavity. The removal of certain organs from the victims' bodies was explained by the assumption that the killer had some knowledge of anatomy or surgery. However, all the names, the exact number of victims, as well as the identity of Jack the Ripper still remain a mystery.
First place in the list of unsolved mysteries of the world is occupied by the Bermuda Triangle - a geographical area with an area of 4 thousand km. sq. in the Atlantic Ocean. It is considered the site of many (more than 100) unexplained disappearances of ships, yachts and aircraft. To explain the mysterious accidents, most put forward various hypotheses from unusual weather phenomena, magnetic anomalies, giant rogue waves, to abductions by aliens or Atlanteans. Most famous case Associated with the Bermuda Triangle is the disappearance of five Avenger-class torpedo bombers. These planes took off from the US Naval Base in Fort Lauderdale on December 5, 1945 and never returned. Their wreckage was never found.
It seems that mysteries and secrets no longer exist in the world - they have all already been studied and revealed. It turns out that this is far from true. There are still secrets that man cannot reveal. Here are some of them. Most of the riddles are associated with all kinds of inscriptions and texts, the essence of which defies understanding.
Some of these items are discovered on recordings made on wooden tablets. They are decorated with rows of original symbols. If scientists could decipher them, then the reason for the appearance of the giant sculptures of the island would be clarified. The world learned about the “notes”, called rongo-rongo, from monk Eugene Eyraud, who visited the island in January 1864. Until now, mysterious messages remain “closed” to us.
In the USA there is a monument erected in the modern era - in 1979. However, it is puzzling and shrouded in mystery about the cause of its occurrence. It is called the Georgia Tablet and consists of 6 massive granite slabs, located according to certain astronomical events. The inscriptions are made in languages known to us and contain the commandments of the “Age of Reason” movement. Although the words can be read and there is no mystery in this, the reason for the construction and the authorship of the grandiose monument continues to intrigue. Some suggest that the carved rules of life established secret society, guided by the structure of the new world order.
Another example of cryptic inscriptions is found on the Kryptos sculpture, created in 1990 in the USA. There are three curved plates with a seemingly random row of letters. The contents of two have been read, and the third continues to excite the unconventional inquisitive minds of the world.
For lovers of forensics and detective genre The name Zodiac is well known. This is a serial killer who the police were never able to catch (1968-1969). He sent letters to newspaper editors, where he conveyed information about himself in encrypted form. Several of these sheets have been deciphered, some of them continue to be a mystery. As does the criminal himself, who goes by the pseudonym Zodiac.
Once-astronomer Jerry Eyman detected an extraterrestrial signal. He circled it in red and wrote “Wow!” next to it. What these sounds were and where they came from is shrouded in mystery. However, this signal, adopted in 1977, was called “Wow!”, that is, “Wow!”
The Case of the Mysterious Dead Man which was found on the shore of the Australian town of Adelaide, was named “TamanShud”. According to the words found in his pocket. They were written on a piece of paper torn from a rare old book authored by Omar Khayyam. Later the same book was found. on her back side Words similar to a code were discovered. No one can solve it to explain the man’s mysterious death.
There are quite a lot of ancient monuments in England. But the monument that stands out among them is located in the county of Staffordshire. It was erected in the 18th century and conveys a copy of a painting by a certain artist Poussin, depicted in a mirror version. Below it is an inscription that still raises questions among scientists. It is believed that it contains an encrypted key indicating the location of the Holy Grail, hidden by the Templars.
One of the coolest puzzles in archeology today is the Phaistos Disc. It got its name from the place of discovery - the city of Festus in Cyprus. It is known that this is an example of ancient, the very first writing in Europe. To transcribe a short recording made ancient people, you need to have at least one more similar object with the same signs. However, the Phaistos disc is still the only one of its kind. And his secret has not been revealed.
Treasure hunters and romantics know about Bale's cryptograms. There are three of them in total. According to those who read the treasure brochure, it indicates the location and amount of wealth. But no one has yet established how true this information is.
Finally, the most incredible mystery lies in the book, named after its first discoverer, Voynich. This is one of the examples of cryptography written in the 14th and 15th centuries. Neither the language nor the author's name are known. No one has been able to decipher the records for certain.
There are so many in the world unsolved mysteries and secrets that even make you feel a little uneasy! These secrets higher worlds Someone is constantly trying to comprehend, but once again fails. Ciphers, encoded messages, mysterious signs in the margins, cryptograms, etc. - all this intrigues not only scientists, but also ordinary people. Each of us, at least once in our lives, thinks about one of the many mysteries of our universe. Or maybe someone else has yet to solve it?
Mysteries are all around us.
How many films have been made and books written about how to solve these mysteries, but all these films are just science fiction. In fact, neither the world-famous manuscripts nor the complex messages to descendants from their ancestors have ever been fully unraveled.
The Voynich Mystery
It was not possible to unravel the unknown language in which the manuscript was written. In 1912, Wilfrid Voynich, an antiquarian book dealer, acquired a very strange book. All of its 240 pages contained completely new letters and numbers (if they were these characters at all). In addition to words in an incomprehensible language, the book also contained diagrams and illustrations that demonstrated incomprehensible events and also depicted unimaginable plants. Mystery? And what a one! It was not possible to determine who the author of the manuscript was. But scientists were able to determine the time period in which the book was created - 1404–1438.
The Voynich Mystery Manuscript No one has tried to decipher the handwritten manuscript, but all in vain. But it doesn’t look like the author of the text simply decided to make fun of his descendants and drew scribbles to mislead everyone. Today there are a large number of theories in which the great world scientists trying to uncover the secret of the book. Some think that this is a manual on alchemy, others - 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 spare his personal time, effort and money to create it!
Secrets of the higher worlds! A difficult to understand, encrypted and not completely solved riddle on a sculpture located near the CIA in the USA - this is the sensational Kryptos! The sculpture was created by master Sanborn, and the four encryptions on its surface have never been fully solved (despite this “neighborhood” with the CIA). Scientists managed to solve the first three riddles, but they are still struggling with the last one (despite the artist’s hints that the answer to it is encrypted in the first cipher). 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.
Finding Bale's Treasure
Thomas Bale in early XIX century was able to extract treasure during the development of gold deposits in Colorado. It is unknown what motivated this man, but he decided to encrypt the location of real wealth from a large amount of precious metals and stones. For this he used a set consisting of three encryptions. Of these, only the second was decoded, and the key to it was the Declaration of American Independence. This code indicated the area where the treasure is located, but the exact location of the cache is still unknown. Many seekers of adventures 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 Monument, created in the 18th century in Staffordshire. Many people 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, but 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 Templars encrypted the secret of finding the Grail. Many celebrities tried to decode this code, including Charles Dickens and Darwin.
Writing system or Rongorongo
Mysterious signs depicted on artifacts and called Rongorongo were found on Easter Island. Scientists believe that these may be writing systems invented by different branches of humanity. 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 actually did not come from Earth. Human communication with an extraterrestrial civilization lasted only 72 seconds, 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 at 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 Indiana Jones himself would be unable to solve if he existed in reality, 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. This disk contains some strange symbols. Their similarity with the hieroglyphs of ancient Chinese written languages is visible. Supposedly the secrets ancient world contained in this message, because it is at least three thousand years old, made in the second millennium BC. The Phaistos Disc is the most important of all archaeological mysteries.
Mysterious underwater world
Secrets underwater world interesting to scientists and ordinary people on all continents. Learn about ancient civilizations that lived before Flood, reveal the secrets of Atlantis that went under water and solve other most complex tasks related to Hydrocosmos - this is important for understanding our history. And if earlier they devoted a lot of time to studying the underwater world, now they have switched to to a greater extent for space exploration. But there are also many secrets in the depths that have not yet been comprehended!
Who are NZOs?
Unknown noises are recorded using modern acoustic devices (hydrophones). For the first time, they were used by American military services to track the movement of enemy submarines - the USSR. With the help of the devices 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 completely revealed to scientists, but they concluded that in the ocean someone was sending targeted, conscious signals. received the name NZO - unidentified sound object. And who issues these signals has not been established to this day. Maybe these are messengers from the ancient world, aliens, sea monsters or someone else?
"Quakers" of the World Ocean
Great scientists tried to answer the question of who makes the interesting “kwa-kwa” sounds underwater. Maybe it's a huge sea frog? Doubtful! It all started with the interest of sailors who served on submarines in this phenomenon. Using hydroacoustic devices, they picked up strange signals and called them Quakers. This name is even mentioned in the official documentation.
The sound came from objects circling around the boats. This is exactly what was established thanks to direction finding. The strange creatures, which could not be detected, seemed to be 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 the creatures to a specific area and then they left it, saying their usual “kwa-kwa” in parting. What it was is still a mystery. So far, scientists have stopped working on it (or are doing it unnoticed by large masses of people, so as not to spread panic), but the sounds have not disappeared and still bring fear to sailors.
This anomalous zone does not reveal one iota of the secrets of the underwater world, but only confuses researchers even more. Complex calculations, great research - but the mystery is still not solved. Since 1492, this place has been considered at least strange and frightening. The glow of water and sky, tongues of flame, a frantic compass needle - all this is noted in the notes of Columbus’s own expedition. In 1840, the place located near Bermuda was given the informal name of the triangle. In this area, a self-moving ship was then found, which was completely without a crew. Where the crew and thousands of other people who disappeared in this area after the strange discovery went is unknown to modern science.
Not only ships have disappeared and are disappearing in this place, but also aircraft. Moreover, it has never been possible to find any debris or remains. But scientists studying the seabed in the Bermuda region came across a huge pyramid, several times larger than the famous pyramid of Cheops. The walls of this structure are absolutely smooth - there are no plaques, 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, were not fully explored. The ocean is still a mystery to us today, one that 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 has disappeared from view
The world only learned thousands of years later that there was another continent. And searching and researching it will take the same amount of time. The secrets of the underwater world are revealed only to those who are persistent! Among representatives of the ancient world, Aristotle mentioned Atlantis. But words are words, but evidence of the existence of the continent in the form of remains of civilization has not yet been found. They say that not all of the Atlanteans perished and founded their city in Tibet. And Mount Kailash is nothing more than 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. But to believe them or not is up to you to decide!
The secrets of the ancient world, the depths of the sea, one generation to another - this has always aroused and continues to arouse interest among people. Great scientists have not yet been able to solve many mysteries. Maybe you will be the one to do this, write in the comments!
Many scientists have been trying to unravel the mysteries of the past for decades, putting pieces of the puzzle together. But there are artifacts and historical moments that are still shrouded in mystery.
1. Nazca geoglyphs
Geoglyph is a drawing on the surface of the Earth. In Nazca, similar images are made in the form geometric shapes or animals. It looks like they were carved on a hard surface.
To a person on the ground, they appear to be a plexus of lines. yellow color. Only once in the air can you see full-fledged figures: fifty-meter monkeys and spiders, condors 120 meters wide, or lizards one and a half times longer.
No one can say exactly how old the geoglyphs are. They can only be dated approximately. It has been proven that all this was created in different times. The first of them appeared in the 6th century. BC e. And the last ones - in the 1st century AD. e.
2. Mummies from the swamps of Europe
Back in the 17th century, it was mentioned that human mummies were found in the peat bogs of Denmark, Germany, Ireland and neighboring countries, which were perfectly preserved. Some are even worthy of display in museums.
Each body found was carefully studied by many specialists. Traces were found on everyone violent death: cut throat, affected areas from strangulation and blows, broken major bones, punctured head. Sometimes all at once.
For example, the “man from Lindow” lost his life due to an ax in his skull. The "Boathouse Woman" died because of the letter V, which was found deep in the back of her head. The “Kayhausen teenager,” who was no more than 15 years old, was found tied up so tightly that he could not even move.
Until now, many experts argue about what exactly it was: execution or sacrifice. After all, each of those found was dealt with cruelly.
3. Easter Island Statues
It is known that graceful stone creatures are the remains ancient civilization. They are noticeably different from those seen in other parts of the Pacific Ocean. 
The structures were first noticed by the Dutch traveler Jacob Roggeveen, who ended up on the island on Easter Day.
In 1955, Thor Heyerdahl, with the help of local residents, was able to erect one such statue vertically in two weeks. Using beams, they lifted the block several meters and placed large stones under it. This was repeated until the sculpture was in the desired position. But how exactly the hats weighing several tons ended up on their heads is not yet known.
4. Pope Joan
Medieval biographers report that Pope Ionna was born in 882. Since childhood, she loved to study and as a teenager she went to Athens to obtain the necessary knowledge. At that time, any education related to religion was unavailable to the fair half. Therefore, she decided to impersonate the young man John the Englishman. 
When the girl ended up in Rome, she was noticed due to her learning, beauty and piety. After some time, she managed to become a cardinal. And after Pope Leo IV was appointed successor. From the outside, no one had any idea about the trick. But during the next festive procession, Joanna suddenly gave birth to a child right in front of everyone. Soon she died.
After this, starting from 1000 and for five centuries, a mandatory ceremony was carried out, during which the gender of the chosen one for the throne was checked.
This story was considered authentic back in the 13th century. Already in the 15th century they decided to challenge it. In the 16th century, historians had little doubt that this was all fiction. It was believed that the legend appeared as a result of someone's joke, when women dominated the Pope's court - 920-965.
Similar phenomena were noted in late XVI century, when Alexander VI Borgia appointed his mistress as a “medieval accountant”. At the same time, her brother, at the age of 25, without having the corresponding rank, became cardinal-treasurer and bishop of three dioceses. After that, he took the throne under the name Paul III.
It is also known that during the military campaign of Alexander VI, by his own appointment, his youngest daughter was on the throne.
5. Tomb of Genghis Khan
Until now, the best minds in the world have not been able to figure out where exactly the grave of the famous Genghis Khan is located. This place attracts many. It is of unique historical value. In addition, according to legend, incredible wealth is hidden in the ground along with the deceased. According to some estimates, two billion dollars worth of precious stones, weapons and gold can be found in the grave.
After his death, Genghis Khan's body was returned to his place of birth. Now this is Khentii aimak. It is assumed that the great military leader is buried next to the Onon River. Along the way, everyone who met the funeral escort was killed. The slaves who performed the burial were slaughtered. And then the executioners who carried out the execution also died.
There are several legends that explain why searchers fail to find the grave. According to one of them, Genghis Khan’s followers laid a riverbed directly above the burial. On the other hand, a thousand horses were driven across the dug up ground, and then trees were planted on top.
6. Origin of the Basques
The Basques are considered one of the most incredible historical mysteries. At one time they occupied a small part of modern Spain and France. The first thing that is noted is that this people had a unique language that did not overlap with others present in neighboring regions. Genetics were also able to establish that these are people who had the highest percentage of Rh factor in their blood - 25. The difference between these people and others living in the neighborhood stands out noticeably. 
Most scientists believe that the Basques can safely be called the indigenous inhabitants of Europe. They came from the Cro-Magnons, who appeared in these places 35 thousand years ago. Presumably, this people decided not to change their location anymore, since no evidence could be found to refute this until the arrival of the Romans.
7. Time Travelers
Scientists in Lately More and more people are confident that time travel is possible. And numerous facts serve as proof.
For example, this photo shows the opening of the South Fork Bridge in British Columbia, which occurred in 1941. In the frame you can see a person who clearly stands out from the rest.
He has short hair, dark glasses, a sweater over a T-shirt, and is holding a modern camera.
This image can often be seen these days. But for the 40s it seemed strange. Experts conducted their own investigation, during which they managed to find the person who participated in those events. But, unfortunately, he did not remember the “strange” stranger.
The authenticity of the photo has been proven several times using various analyses.
8. Ancient Swiss watches
This small object was found in a Ming Dynasty burial site. The tomb was opened in 2008 during the filming of a documentary. To the surprise of the operator and archaeologists, a Swiss watch was found inside.
The former head of the Guangxi Museum, who then took part in the expedition, shared: “We were removing soil from the surface of the lid when suddenly a small piece of rock bounced off and fell to the floor from metallic sound. The object looked like a ring. But when we cleaned it of dust, we discovered a miniature dial.” 
At the same time, we were even able to see the Swiss inscription inside. The Ming Dynasty ruled China until 1644. At that time, they had no idea that such technologies would ever become a reality. At the same time, experts claim that this tomb has been closed for the last 400 years and no one has ever been in it.
9. Ancient computer
In Kamchatka, several hundred kilometers from the village of Tigil, the St. Petersburg University of Archeology found unexplained fossilized remains. 
According to the head of the excavations, this discovery surprised scientists, but could completely change history. Special analysis showed that these were originally metal parts that form a mechanism that is not yet understood. The most amazing thing is that the find dates back 400 million years.
10. Voynich Manuscript
The Voynich Manuscript is a mysterious book from the 15th century that no one has yet been able to decipher. It was written between 1404 and 1438 unknown author. In addition, the words inside have still not been translated. They are made up of a strange alphabet, which no one knows about either.
Book size: 23.5×16.2×5 cm. It contains about 240 pages. The manuscript has been repeatedly studied by many cryptographers, archaeologists and historians. No one could even come one step closer to deciphering even a single word. 
After futile attempts, some experts came to the conclusion that the pages contained random characters that were in no way related to each other. Others adhere to the theory that the paper contains not only information telling in detail about that time, but also data about the future.
11. Jack the Ripper
Jack the Ripper is a serial killer (or killers) who committed several high-profile crimes in London in 1888. All his victims girls lung behavior from the poorest neighborhoods. The maniac cut their throats, after which he opened the abdominal cavity. He took some organs. It is believed that the killer had good knowledge of anatomy. 
Only recently, a collector who purchased a shawl allegedly belonging to one of the victims handed it over to specialists. Using careful testing, they isolated the DNA of the alleged maniac. It turned out to be Pole Aaron Kosminsky, who came to England to work as a hairdresser. Despite this, many have criticized this method, since it does not definitively prove the emigrant's involvement in the murders.
12. Crystal Skulls
Many experts are already trying to solve the mystery of the origin of crystal skulls. for a long time. No one yet knows who could have created them and how? 
Scientists talk about 13 heads made of rock crystal. All of them are kept in museums or private collections. Artifacts have been found in Tibet and Central America. The exact time of their production has not yet been established. In addition, the tools with which this can be done are not known.
13. Ancient aircraft
The Incas, Aztecs and other peoples living in pre-Columbian America are known not only for their amazing pyramids and strange rituals. They also left behind many small figurines. One of them turned out to be the so-called “ancient aircraft”, which resemble modern aircraft in similar elements. 
Initially, experts believed that these were simply figurines of insects or birds. However, it turned out that they have parts more similar to modern aircraft: stabilizers, landing gear, etc. It was not possible to find large aircraft of that time. What the ancient tribes wanted to show by this is not yet known.
14. Phaistos Disc
The Phaistos Disc is a small clay round tablet that was found in 1908 in the Minoan Palace in Italy. Her secret still remains unsolved. 
There are various unknown symbols on the plate. It is believed that this language was created in the 2nd century. BC. Some people think that the drawings resemble the hieroglyphs of Crete. However, they cannot find the decryption key. This disk is one of the most famous mysteries in archeology today.
15. The Taman Shud case
So far, the best inspectors have not been able to solve the Taman Shud case. It was also called "The Case of the Mysterious Man of Somerton."
The case was opened when the body of a man was found at half past seven in the morning in the city of Adelaide, Australia. He was on Somerton Beach. It was never possible to establish who the deceased was. Then experts found out that death occurred as a result of drug poisoning.
In addition, a piece of paper found in a secret trouser pocket caused a stir. There were only two words written on it - “Taman Shud”. These were words taken from a rare book by Omar Khayyam. 
The police managed to find the required copy, which was missing the last page. On the back were several words written in pencil, resembling a code. It was never possible to find out what exactly was written there.
To this day, this case remains one of the most confusing and mysterious.
But many secrets remain shrouded in darkness. Below are ten of the most famous cases of mysterious deaths or disappearances in history that still remain unsolved mysteries.
In February 1959, a search team discovered in the north Ural mountains abandoned Dyatlov tent camp. A tourist group of 9 people led by Igor Dyatlov went on a ski trip and went missing. The tent discovered by rescuers was torn, but inside it were the shoes and clothes of tourists, while to the side there were traces left by people barefoot or wearing socks.
The bodies of the Dyatlov group members were found only in May, when the snow melted. As it turned out, most of the tourists died of hypothermia, but two of the group had fractured skulls and broken ribs, and one had no tongue.
The official version of the Soviet investigation was “death as a result of a devastating natural force,” which most likely meant an avalanche. But what really happened to Dyatlov’s group is still unknown to anyone for certain.
There are the most different versions happened, ranging from an attack by wild animals or Bigfoot to mass psychosis caused by exposure to low-frequency signals. They don’t even rule out the possibility of an alien attack, citing the fact that UFOs were often observed in those places. But the history of the Dyatlov group remains a mystery.
Tamam Shud and rubai of Khayyam
"Tamam Shud" is the most famous mysterious death of a person on Australian soil. The story got its fancy name from the Persian words written on a piece of paper that was found in the pocket of the deceased. The body of an unknown man was found on a beach south of Adelaide in 1948. No documents confirming his identity were found on him. The only items found on the deceased were cigarettes, a ticket for a commuter train, a comb and a piece of paper with the mysterious inscription “Tamam Shud,” which means “The End” in Persian.
Interestingly, as it later turned out, the piece of paper was torn from a rare edition of the book “The Rubaiyat of Omar Khayyam.” The mysteries became even greater when, as a result of the autopsy, it turned out that the dead man was most likely poisoned. Police subsequently found a book of poetry from which a piece of paper with the words “Tamam Shud” had been torn out. A phone number was found in the book, which led the investigation to an Australian resident. The woman claimed that she had never known the murdered man, and that the book had indeed once belonged to her until she lent it to someone.
In addition, cryptic handwritten inscriptions were found in the book found. In 2009, Derek Abbott, a professor at the University of Adelaide, suggested that the book's encoded writing could be the result of manual encryption or decryption - a spy technique that could be based on text from the book (in this case, the Rubaiyat of Omar Khayyam). . So, there is every reason to assume that the “Tamam Shud case” is somehow connected with the activities of a foreign spy in Australia. But the identity of the deceased still remains a mystery to society.

The mystery of flight number 19
Flight 19 was the name given to a group of five Avenger military aircraft that mysteriously disappeared during a daytime training flight off the coast of Florida in December 1945. This mysterious disappearance became one of the basis for the emergence of numerous legends about the mystical.
All 14 pilots who were on board the five planes, as well as 13 crew members who were sent to search for them, mysteriously disappeared. No bodies or aircraft wreckage could be found.
This disappearance gave rise to the legend of the existence of a deadly Bermuda Triangle between Florida, Puerto Rico and Bermuda, where the largest number of planes and ships disappear without a trace. But the US Coast Guard does not see anything supernatural in this.
It was flight number 19 that gave rise to myths about the Bermuda Triangle and stories about the mystical aura of this place and an encounter with a UFO here, which are reflected in world literature and cinema. For example, the story of mysterious disappearance American bombers are used as the basis for Steven Spielberg's science fiction film Close Encounters of the Third Kind.
Mysterious Mr. Cooper
Dan Cooper is a mysterious criminal who managed to hijack a Boeing 727, but at the same time remain an unknown hijacker. This mysterious story took place on November 24, 1971, on board an airliner flying from Portland to Seattle. Shortly after takeoff, a man who had booked the flight under the alias "Dan Cooper" claimed that he had carried a bomb on board in his briefcase. The hijacker demanded that the pilots land at Seattle airport, where he would receive a ransom of $200,000 and a parachute.
After the requirements were met, the passengers were able to leave the plane, and the invader and the pilots took to the skies again. At an altitude of about 3000 m, the mysterious Mr. Cooper jumped out of the plane with a parachute, taking the ransom he had received. Since then, no one has seen this man again.
FBI searches have yielded no results. Investigators concluded that Cooper most likely did not survive the jump from the plane. But there are numerous versions according to which the mysterious hijacker is alive. In 2016, a documentary was even released, the creators of which claimed that the hijacker was still alive and now lives in Florida under the guise of former veteran war.
Murder at the South Pole
On May 12, 2000 (in the midst of the Antarctic winter), Australian astrophysicist Rodney Marks died under mysterious and unclear circumstances at the Amundsen-Scott station located at the South Pole. Since winter flights to the South Pole are dangerous, the body of the deceased was kept frozen at the station until spring, and then sent to New Zealand. An autopsy showed that the scientist died of methanol poisoning.
In the process of investigating this mysterious death, 49 people were interviewed who at that time spent the winter at the Amundsen-Scott station. New Zealand police ruled out suicide, suggesting it was unlikely that Marks could have accidentally poisoned himself. In 2008, the case was closed, and official version The death of the scientist was called suicide. But it was this case that received publicity in the media as “the first murder at the South Pole,” the mystery of which was never solved.
Héloïse Bosquet de Wagner-Werhorn, better known to history as the “Baroness of Galapagos,” was a young Australian who mysteriously disappeared on the island of Floreana in 1935. Located in the eastern Pacific Ocean and part of the Galapagos Islands, the island became well known in Germany after it was “colonized” in 1929 by a German couple, Friedrich Ritter and Dore Strauss, who settled on the land in a primitive hut made of stones and driftwood They served as a clear example for other German families, who saw the island of Florean as a utopian paradise on earth.
In 1933, the “baroness” arrived on the island with her two lovers, Robert Philippson and Rudolf Lorenzo. After they built a house on the island, Eloise announced her plans to create a luxury hotel here with elements of aristocratic life against the backdrop of the simple colonists of Florean.
On March 27, 1934, Baroness Heloise mysteriously disappeared along with Philippson. Rudolph claimed that they boarded a yacht passing by the island, which was heading to the shores of Tahiti. However, no records were found that could attest to the passage of any ship past the island at that time.
No less intriguing in this mysterious story became the fact that a few days later Rudolf Lorenzo hastily left the island on the ship of a Norwegian fisherman who was heading to the shores South America. A few months later, their mummified bodies were discovered on a wrecked ship washed ashore on the island.
There is an assumption that Lorenz killed Eloise and Robert, and other colonists of the island helped him hide the evidence of this murder, but this has not been reliably proven. The mysterious disappearance of the “Baroness of Galapagos” is still one of the most mysterious murders of the 20th century.
The American pilot is one of the most famous female aviators in the world. In May 1932, she became the first woman to fly solo across the Atlantic by air, and in 1935 she flew solo from Honolulu, Hawaii, to Oakland, California.
In July 1937, while attempting to fly around the world, Amelia Earhart's plane disappeared over Pacific Ocean. The search by the US Coast Guard lasted two weeks (and went down in US history as the longest and most expensive), but was unsuccessful - no remains of the plane were found.
According to one unconfirmed version, the crashed plane and its crew (Amelia and her navigator Fred) could have ended up with the Japanese. There were even rumors that a white woman and a man were captured by the Japanese and were later executed. Another theory of Amelia’s mysterious death was partially confirmed when artifacts were discovered on one of the Pacific islands that are part of the Phoenix archipelago that could well belong to the legendary pilot.
An examination carried out in 2016 even showed that the remains discovered on the island could well belong to Earhart. But for certain, what happened on Amelia’s last flight remains a mystery, hidden by time and the ocean.
Mysteries of the pioneers of Everest
On June 4, 1924, British climbers George Mallory and Andrew Irwin set out from Everest Base Camp to conquer the inaccessible peak in the hope of becoming the first people to do so. Four days later they were spotted by their colleague, who was located on the northeastern part of the ridge. But the clouds hid the figures of the climbers, and no one else saw them.
Researchers and climbers believe that Mallory and Irvine likely survived the ascent to 8,848 m, but died during the descent from the mountain, presumably on June 9, 1924.
In 1933, Irwin’s ice ax was found on the top of the mountain, which confirmed the climbers’ guesses that Mallory and Irwin reached a height of 8564 m. In 1999, an expedition discovered Mallory’s remains on Everest at an altitude of 8230 m.
Some climbers claimed to have seen another body nearby. It is likely that it was Irwin. And although the finds confirm the death of the pioneers of Everest, the intrigue still remains as to whether Mallory and Irwin really reached the top of the mountain shortly before their death or whether this is all speculation that has no basis in reality.
Mystery "MaryCeleste"
On December 5, 1872, approximately 640 km east of the Azores, in the eastern part of the Atlantic, the American merchant ship Mary Celeste was discovered drifting with a partially preserved sailing equipment. On board the ghost ship there were a lot of supplies of water and provisions, which made it possible to safely travel across the sea for many months.
The only lifeboat on board the ship was missing. Most likely, it was on it that people abandoned board, but what is surprising is that, apparently, this was done not in a storm, but in good weather. No less surprising was the fact that people left the ship, leaving all their belongings on it. The cargo transported on the ship was also undamaged. Barrels of alcohol were found in exactly the quantity in which they were listed during loading.
The ship left New York, and a month before its discovery, without a crew, it was spotted in Genoa, Italy. At that moment there were 10 people on board the ship: 7 crew members, as well as the captain with his wife and two-year-old daughter. The reason why the Mary Celeste was empty still remains a mystery.
In 1884, several years before the Sherlock Holmes stories, Sir Arthur Conan Doyle published a fictional story told from the perspective of the hero who survived the Mary Celeste. In the story, narrated by the master of the detective genre, the crew was killed by a vengeful serial killer from the ship's crew. The story turned out to be more popular than real story, and was even often presented as reality in some newspapers.
There are other versions that explain how the Mary Celeste turned into a ghost ship. There is an assumption that the crew abandoned the ship due to the threat of an explosion from alcohol vapor leaking in the cargo compartment. According to another version, the ship was attacked by Moroccan pirates, who put people on a boat and left the cargo on board. In 2007, documentary director Anne McGregor presented another version of the events on board the Mary Celeste. According to it, the captain, anticipating a storm, saw land on the horizon and decided that it was safest to go ashore in a boat. But this could have turned out to be a fatal mistake, and the boat with its crew sank, while the ship was able to survive the storm and subsequently drifted across the sea without a crew or captain.
