Here are eight of the world's biggest unresolved mysteries, ranging from the little-known civilization behind one of the world's earliest advanced societies to our search for extraterrestrial life.
8. The Void in the Great Pyramid
Researchers examining the Great Pyramid of Giza uncovered an empty spot inside the pyramid about 30 meters long and directly above the Grand Gallery a few years ago. In 2015, Cairo University and the Heritage Innovation Preservation Institute collaborated to launch the scan pyramids research initiative.
Scientists discovered a gap or open room buried in the pyramid above the pyramid's grand gallery using an imaging method known as myography.
The scientists employed a variety of sensors to detect particles produced by cosmic ray collisions with the Earth's atmosphere. The pyramid's stones then absorbed the particles that hit them. Three different devices revealed a vast open area or potentially numerous secret rooms in a sequence.
Assuming that this is the first new structure discovered in the pyramid since the 1800s, it could store amazing wealth, yet many scientists are suspicious due to the emptiness. Some speculate that it was left as part of the construction process, either as an interior ramp to construct the pyramid's top or even for structural reasons.
However, who knows, perhaps there is a treasure there that has been lost for all this time. For the time being, scientists do not want to risk harming the monument by studying the room. Without any visible entries into the room, we may have to wait a while to find out what's really within.
7. The Bronze Age Collapse
The Late Bronze Age civilizations abruptly collapsed just after 1200 BC, and the world entered a dark age. For a long time, archaeologists and historians have been perplexed as to what caused this seemingly random event.
The cultural decline appears to have begun with the invasion of Egypt in 1777 BC, according to anthropologist Eric Klein of George Washington University. According to a wall relief in Ramses the Third's tomb, the intruders were simply known as the Sea Peoples. According to the account depicted in the image, Ramses the third defeated the invading army, but ancient Egypt and its surrounding lands suffered as a result.
Various ancient nations, like the Egyptians, Babylonians, Minoans, and Mycenaeans advanced maritime people for their time, effectively collapsed like dominoes. Sites where once-mighty civilizations resided show indications of rapid violence and abandonment, as well as the apparent loss of languages, architecture, settlement patterns, and art.
Hattusa, the Hittite capital, was burned to the ground and abandoned, while coastal cities such as Gaza and Canaan were demolished. So, why is there so much devastation, especially out of nowhere? It's most likely the result of a succession of tragic occurrences.
One possible cause for the collapse is that all of these ancient societies were intertwined and relied on one another for commerce, particularly when it came to obtaining tin and copper for bronze production. The domino effect makes sense from the perspective of fencing during the Bronze Age and for other economic reasons.
The driest Bronze and Iron Age years were between 1250 and 1100 BC, when all of those civilizations fell apart, according to a pollen examination of a sample from the Galilee area conducted in 2015.
showing that while drought may have had a role in their demise, a collapse of this magnitude, according to Cline, required the right mix of causes, or a perfect storm of catastrophes, and cannot be explained away by the ones I just mentioned.
Researchers are still divided and confused about the exact sequence of events that created this so-called perfect storm, but some have cautioned that it may happen again, and that modern mankind should not get complacent.
6. The Hanging Gardens Of Babylon
The Hanging Gardens of Babylon, according to ancient literature, were an oasis of luxuriant greenery nestled in the desert surroundings of modern-day Iraq. The 75-foot-high terraces, which cascaded with luxuriant foliage and exotic herbs and flowers, were supposedly created by Babylonian monarch Nebuchadnezzar II as a present to his bride in the sixth century BC.
Philo of Byzantium stated about 250 BC that the gardens had plants cultivated at a height above ground level and that the tree roots were embedded in the upper terrace rather than in the earth. However, it is unknown when the Hanging Gardens were constructed or even if they ever existed.
Despite spending decades digging Babylon, archaeologists have uncovered no evidence of them, and there are no first-hand testimonies known to exist; only secondhand reports were written after the gardens were reportedly destroyed exist.
Stephanie Dahle of the University of Oxford proposed in 2013 that the gardens were real and were located 300 miles from Babylon in the Assyrian metropolis of Nineveh. She also claimed that the gardens were erected by Nebuchadnezzar II's adversary, the Assyrian king Cynic Arab, in the early 7th century BC.
One thing is certain: if the Babylonian Hanging Gardens existed, an engineering achievement would have been necessary to keep them watered and healthy in the harsh desert environment. Dali's theory is supported up not just by ancient Mesopotamian texts, but also by uncovered evidence of a complex aqueduct system at the site where she believes the gardens were built.
Unfortunately, this enigma will likely never be addressed because wars and theft have severely harmed both Fabula and Inva in recent decades.

5. Mohenjo Daro
During the 3rd millennium BC, the ancient Indus River Valley Civilization at Mohenjo-Daro in modern-day southern Pakistan (before it was in India) arose. The roughly 500-acre city has a well-organized street grid and a sophisticated drainage system.
However, despite being one of the earliest known city areas in human history and the largest and best-preserved city of the Indus civilization, the University of Pennsylvania's desegregate pasal stated that otherwise, it's pretty faceless, in other words, little to nothing is known about mohenjo- daro's former occupants.
The site was first visited by archaeologists in 1911, and excavations began a decade later. Mohenjo-Daro had a 900 square foot pool called the great bath, which was fed by water from the Indus River.
Houses also boasted excellent plumbing, including far-ahead-of-their-time baths and toilets, as well as a sewage system and 700 freshwater wells. Palaces, temples, royal tombs, and other buildings of worship and governance are strikingly absent from Mohenjo-Daro, implying that, unlike other cultures of the time, such as the Egyptians and Mesopotamians, the city was not organized around state concerns.
Mohenjo-Daro was home to between 20,000 and 40,000 people. After 600 years, the city inexplicably crumbled, and no one knows why. Violent invasion or a change in the Indus River's course, for example, could have caused citizens to relocate solely for agricultural purposes.
4. William Shakespeare
You already know that William Shakespeare was a brilliant playwright and poet and that his works have historical and cultural significance. Although he lived in the 16th century and resided in London before returning to his childhood home of Stratford-upon-Avon, some experts feel that William Shakespeare did not compose all of the works that we believe he wrote.
To be clear, no one doubts that he lived, but he did not write the books himself. Why is this? Because certain aspects of Shakespeare's works, such as his use of French and knowledge of other countries' court proceedings and intricate legal and political matters, clash with his modest identity.
Aside from a few signatures and marriage and birth records, the man's life is glaringly devoid of official paperwork. Surprisingly, none of Shakespeare's paperwork refers to his 37 plays or 154 sonnets. Because of the lack of proof of ownership of his work, as well as his modest beginnings, many people have questioned if Shakespeare's work was ever truly his.
The playwright's genuine identity has been questioned by the most famous people in history like Charlie Chaplin, Henry James, Sigmund Freud, Mark Twain, and Helen Keller. So, if Shakespeare wasn't Shakespeare, who was he? Was it a group of people? Did he pay people to assist him with particular tasks?
Actually, the 17th Earl of Oxford, Edward de Vere, is the most popular candidate; he visited all of the locations mentioned in Shakespeare's plays and was a highly educated trained lawyer, making him appear to be more qualified as a playwright than the simple man from the countryside at first glance.
People who believe the Oxfordian theory say that he may have hidden his identity because of the politically outspoken character of the plays and the seeming shame that comes with a profession in playwriting. What do you suppose it was? Was it Shakespeare, someone else, or a group of people? Could he have been a spy?

3. The Mary Celeste
On November 7th, 1872, the American commercial ship Mary Celeste set sail from New York City for Genoa, Italy, with seven crew members, including Captain Arthur Briggs, his wife, and their baby daughter.
The Mary Celeste was discovered in stormy waters around 400 miles east of the Azores by crew members of the British ship Gracia less than a month later. Captain David Morehouse was perplexed by the sight because the Mary Celeste had arrived in New York eight days before his ship and should have already arrived at her destination.
He veered off course to assist the stranded vessel, only to learn that it was empty. The crewmembers' belongings were still on board, along with a six-month supply of food and water, and the cargo supply was undamaged; nevertheless, there were three and a half feet of water in the ship's bottom, and the only lifeboat had been lost.
So no one knows what happened to the Mary Celeste crew. Theories have circulated over the years that they were murdered by a vengeful former slave, homicidal sailor, sea monster pirates, or even a dangerous waterspout, but the ship was in remarkably good condition and well-supplied, ruling out both natural disasters and looters, as well as any other logical reason for Briggs to order the crew to abandon ship.
It's possible that the de gracias crew was involved in some sort of deception. The Trumans who discovered the Mary Celeste were entitled to salvage compensation, but they only received only one-sixth of the $46,000 that the ship was insured for, implying that the authorities were skeptical of their claims.
According to a 2007 investigation, the Mary Celeste had recently been refitted and debris may have damaged the pumps, making it impossible to visually measure how much water was in the hull, and possibly after navigating off course but seeing land, Briggs may have ordered the crew to abandon the Mary Celeste after all, but we don't know what happened.
2. Amelia Earhart
Amelia Earhart is regarded as one of history's most famous pilots, both as an aviator and as a woman. During an attempt to round the world in 1937, she and her navigator Fred Noonan vanished over the western Pacific Ocean, and searches for her began less than an hour after her final radio transmission.
Since then, explorers have been searching for her lost plane to no avail, and while Earhart's chances of survival were little to none, her fate has remained a mystery. Some even say she's been located but hasn't been identified. On Gardner Island in Kiribati, a woman's remains were discovered in 1940, together with a navigational sextant and the remains of a bonfire.
Following an autopsy, it was determined that the body belonged to a Caucasian woman, most likely of northern European ancestry. Given Earhart's location at the time of her disappearance, it makes sense that she might have ended up in Kiribati, but these findings have been disputed, and the identity of the remains is still unknown.
Other excursions have been conducted in the area since 2001, and more indicators of a woman's presence near the time of Earhart's disappearance have surfaced. One idea is that Earhart may have crashed on or near the island of nakooma RORO in Kiribati, based on an ancient photograph known as the Bevington image, which appears to show landing gear comparable with Earhart's plane.
A mystery photo of Amelia sitting on a pier with her back to us was discovered in 2017, according to a History Channel documentary, however, it was found that the shot was taken two years before her disappearance. There are still unanswered questions, and the lack of closure is not due to a lack of resources.
Last year, renowned explorer Dr. Robert Ballard led a multi-million dollar sea, land, and air search in the hopes of finally solving the eighty-year-old mystery, but the search yielded no trace of Earhart's Lockheed Electra plane.
Despite this, Ballard hesitated to declare the search a failure because it at the very least ruled out the region as a prospective location for the plains. This plane exists, according to Dr. Ballard, who told the New York Times in September 2019 that it is not the Loch Ness Monster and that it will be discovered.
1. Where are the aliens?
The search for extraterrestrial life was summed up in the 1950s by scientist Enrico Fermi, one of the atomic bomb's designers, when he suggested the Fermi paradox. It claims that there are billions of stars in the cosmos that are identical to our Sun and that these stars have a very high possibility of having planets circling them that are similar to our own.
If this is the case, there's a good likelihood intelligent life has evolved there as well. So why haven't we found any proof of it? However, despite the fact that it is statistically likely that alien intelligence exists, there is no evidence. According to some calculations, there could be as many as 20 civilizations in our galactic area, but instead of contacting us, they may be deliberately remaining silent.
But why would they do something like this? According to the dark forest idea, all living forms desire to survive, and there's no way of knowing if other life forms will kill you if given the chance. As a result, the best approach is to avoid them entirely.
Other possibilities include the possibility that civilizations on other planets that haven't evolved yet have already died out, or that we simply haven't looked closely enough.
