The Top Unsolved Scientific Mysteries
Thanks to science, we know a lot about the world around us, but there are still plenty of mysteries that experts can’t explain. Scientists are still puzzled by the secrets of the Taos Hum, the Japanese "Atlantis" and Egypt’s Great Pyramids, just to name a few.
Will we ever know the truth about all the strange phenomena left behind by the ancient world and the universe? Check out our list of the most famous unsolved scientific mysteries that are just begging for answers.
The Taos Hum Phenomenon
In the small town of Taos, New Mexico, you may hear a buzzing or humming sound that won’t go away. It’s not a bee or a mosquito, and it’s definitely not just you. The people of Taos have heard the weird hum since the early 1990s.
An Ancient Computer
This recreation of an artifact doesn’t look like much, but scientists believe it was the first computer — a 2,000 year-old computer to be exact. The device, also known as the Antikythera mechanism, was found in a shipwreck in 1901.
Saturn’s Bizarre Hexagon
Located on the north pole of Saturn, a cloud in the shape of a hexagon defies a scientific explanation for its formation. The massive hexagon was first discovered in 1981, and it has remained a giant question mark since then.
It’s raining…blobs of jelly? Jelly rain, better known as star jelly, has been found stuck in trees and laying on grass. It has appeared several times, including once in 1846 in Lowville, New York, and another time in 1994 in Oakville, Washington.
Aliens at Area 51?
Area 51 is a top-secret facility, so nobody knows much about it, other than it’s a military base. Many people think it’s actually the site of a huge cover-up and the facility is hiding space aliens. Area 51 has been the subject of extraterrestrial rumors since 1947, when conspiracy theorists first claimed an alien craft crashed in Roswell, New Mexico, and officials transported the vessel and the aliens to Area 51.
Missing Ships and Planes in the Bermuda Triangle
Notorious for the vanishing of ships and airplanes, the Bermuda Triangle is the area between Puerto Rico, Bermuda and Miami. Paranormal investigators blame everything from monsters and aliens to time warps for the mysterious disappearances. Scientists think it’s probably just waterspouts or methane gas eruptions.
The Unknown South Atlantic Flash
In 1979, Vela satellites recorded an unknown double flash near Antarctica. This event became known as the Vela Incident. What caused the mystery flashes? Researchers believe a nuclear explosion is responsible because satellites previously detected 41 identical double flashes that were known nuclear weapon tests.
Atlantis, is that you? Underneath the waters of Japan, a massive stone formation called the Yonaguni Monument fascinates the world. A diver found the huge stones in 1986, and researchers have visited the site ever since. They discovered the monument is at least 10,000 years old.
Missing Malaysia Airlines Flight 370
On March 8, 2014, Malaysian Airlines Flight 370 departed Kuala Lumpur International Airport and never reached its destination. After only 38 minutes of flying, it lost contact with air traffic control. The plane and its 227 passengers and 12-man crew simply vanished.
The Bloop: Giant Creature or…?
In 1997, the U.S. National Oceanic and Atmospheric Administration (NOAA) detected an ultra-low-frequency, high amplitude underwater sound. Experts thought the sound came from an animal, but the strange part is no animal on Earth can make such a powerful call.
The Oak Island Booby Trap
Near the coast of Nova Scotia, Canada, a bizarre hole with even weirder objects inside can be found on Oak Island. Since its discovery in 1795, many explorers have tried to see what’s hidden at the site. Reports of buried treasure and artifacts inside the hole began circulating and caused excitement.
Submarine Disappearances in 1968
One missing submarine is strange, so when a total of four submarines disappeared in 1968, it became a huge mystery. The missing subs included the USS Scorpion, a Soviet submarine called K-129, an Israeli submarine called INS Dakar and a French submarine called Minerve.
Saddle Ridge Hoard
In 2013, the story of buried treasure became a reality in Sierra Nevada, California, when a total of 1,427 gold coins worth $10 million were found hidden in the ground. It’s the biggest discovery of gold coins ever seen in the country.
Boom! It’s a cannon. No, it must be thunder. Nope, it’s actually — skyquakes? What in the world is that? Skyquakes are unknown banging sounds coming from the sky. The loud booms have been heard all over the planet, including the U.S. and Japan.
The Iron Pillar That Never Rusts
A 13,000-pound pillar stands in the Qutb complex in Delhi, India. Some researchers believe its origin dates back to 402 CE, but the exact date has been heavily debated. The best part about the pillar is that it’s resistant to rust and corrosion, even though it’s entirely made of iron. Whoa!
The Strongest Proof of an Alien Signal
On August 15, 1977, Dr. Jerry R. Ehman detected a signal that supported the theory of extraterrestrial intelligence. Using the Big Ear radio telescope, Ehman searched the universe for life beyond Earth, and he received a compelling narrowband radio signal from the constellation Sagittarius.
An Explosion That Came from Out of Nowhere
On June 30, 1908, a giant fireball flew over and exploded in the wilderness of Tunguska, Siberia. The impact killed several animals, millions of trees and supposedly three humans. With an explosion that was bigger than 1,000 atomic bombs, the Tunguska event is the largest impact on Earth.
The Disappearance of the Roanoke Colony
When 121 colonists disappear without a trace, something seriously weird must have transpired. That’s exactly what happened in Roanoke Island, North Carolina, in 1587. John White, the governor of the established colony, traveled to England to bring back supplies for the settlement.
The Unreadable Book
Researchers have failed to decode the strange language in a medieval book called the Voynich Manuscript. The handwritten book comes with weird text, painted illustrations and diagrams. Many pages contain text written in ink and pictures of alien-like plants or nude figures.
Amelia Earhart Vanished
Amelia Earhart inspired other women to become aviators by becoming the first female pilot to fly solo across the Atlantic Ocean in 1932. The journey took 15 hours and involved a burning engine, but Earhart managed to fly from Harbor Grace, Newfoundland, to Derry, Ireland.
One of the most famous monuments of all time, Stonehenge still has researchers scratching their heads. Standing on the Salisbury Plain in Wiltshire, England, the site is made up of upright stones and stone arches forming a circle. But who built it? Aliens? The devil? Glaciers?
The Moon Landing Conspiracy
Was Neil Armstrong's giant leap for mankind real? Some experts claim the moon landing on July 20, 1969, never happened. Nobody walked on the moon or even got near it. Skeptics think it was all staged and filmed in Hollywood.
In Langley, Virgina, the CIA headquarters is home to a bizarre 12-foot-tall statue by artist Jim Sanborn. He displayed the copper statue in 1990 and named it Kryptos. It's certainly not your ordinary statue. In fact, Sanborn put four hidden messages with 1,800 characters in it.
Mysterious Booms from Deep Space
Scientists jumped for joy after receiving messages from deep space in 2007 — the signals originated 7.9 billion light-years away — but they quickly became puzzled. They couldn't figure out what caused the signals, also known as fast radio bursts.
A 350-year-old rock formation located in Siberia has long had scientists running around for answers. Patomskiy Crater, also called "Fire Eagle Nest," is made of shattered limestone blocks, but scientists are uncertain of the crater’s origin. Is it a meteorite? Maybe even the Tunguska meteorite?
Humpback Whale “Super Groups”
Humpback whales have been known to be solitary, but these days they’ve been feeding in massive groups of 20 to 200. What on earth is causing the behavior? Scientists say they've never seen anything like this and find the sudden change of behavior interesting.
A big part of the universe is dark matter, but the makeup of that dark matter remains unknown. Some experts think it’s made of unidentifiable particles or ancient black holes, but nothing has ever been proven.
Hidden Void in Egypt’s Great Pyramid
What is the Great Pyramid of Giza hiding? Built more than 4,500 years ago, the Great Pyramid is where pharaoh Khufu rests. Thanks to particle physics, a hidden void was found in the largest pyramid in Egypt. More than 100 feet long, the void looks like the pyramid's Grand Gallery.
Giant Stone Spheres of Costa Rica
The stone spheres of Costa Rica look like boring lawn ornaments. However, they're actually prehistoric artifacts with unknown origins. Scientists can't identify how the balls were formed, but they know the United Fruit Company found the stones in the jungle in the 1930s.
Cursed Shipwreck in the Gulf of Mexico
Deep beneath the Gulf of Mexico, a 200-year-old wooden shipwreck rests on the ocean floor. Although the ship was discovered in 2003, studying it has been an extreme challenge. Machines mysteriously break down every time scientists get close to the vessel, inspiring many to claim the ship is cursed. One rover sent to the wreck smashed into the side of the ship. Another retrieved an artifact but then dropped it, never to be seen again.
