What is the Loch Ness Monster?

As far back as the 7th Century, people have reported seeing a Loch Ness monster in Scotland. Can science explain these mysterious sightings?

The Loch Ness is a lake in Scotland that holds the largest volume of freshwater in the United Kingdom. But rather than being known for its size, it is famous for the mysterious legend of the Loch Ness monster. For hundreds of years, people have reported catching a glimpse of a huge creature in the lake while others have shared photos they claim to have taken of this sea creature. The legend is so great that even scientists have been intrigued and many have conducted experiments and come up with theories to try and explain what people could be witnessing.

Painting of plesiosaurs, creatures thought to be most similar to people's descriptions of the Loch Ness monster.

A real creature in Loch Ness?

It has been proposed that Nessie � as the Loch Ness monster is commonly called � could be a prehistoric creature called a plesiosaur, an animal that spanned up to ten meters in length and has long been considered to be extinct. Adrian Shine, the leader of a British team called the Loch Ness Project, has spent over 30 years trying to rationally explain the monster sightings by researching the ecology of the region. If in fact a large creature was living in the lake, there would have to be evidence of a food chain for it to survive. A creature like the Loch Ness monster would most likely eat fish, which in turn would live off large quantities of microscopic animals called zooplankton. There would have to be enough zooplankton in the lake to support populations of larger animals.

A way of estimating the amount of zooplankton in the lake is to examine the quantities of green algae � the bottom rung of the food chain - that zooplankton feed from. Green algae needs some light to thrive, and so by examining how deep down in the lake sunlight can penetrate, researchers can estimate the amount of green algae and following from this, the type of population that could be sustained.

Scientists have calculated that a maximum of 17 to 24 tons of fish live in the Loch Ness. For a lake of its size, it is a small amount, and would be able to keep alive about ten creatures weighing 226 kg each. According to Richard Forrest, an expert on plesiosaurs, ten creatures would not be enough to keep a colony going. �Thirty to forty creatures would be the minimum size of a breeding population,� he says.

In addition, if creatures similar to plesiosaurs lived in the waters of the Loch Ness, they would be seen very frequently as they would have to surface several times a day to breathe. Eye witnesses have often mentioned seeing an animal throwing back its long neck from the water, but Forrest claims that plesiosaurs couldn�t do that. �The simple fact is that a plesiosaur�s neck is too stiff. The bones of the neck interlock and there are tall spines on top of them so the neck can�t go straight out of the water,� he says.

SONAR investigations

But it is not impossible for prehistoric creatures to still be around today. In 1938, South African fishermen caught a gigantic fish that turned out to be a Coelacanth, a prehistoric fish thought to be extinct for the past 80 million years. Because of murky water filled with peat, it has been hard for divers to properly investigate the depths of the Loch Ness and the life that exists there. The advent of SONAR � a measuring instrument that sends sound waves into water and measures distance by calculating the time it takes for an echo to travel back to the source � has proved to be useful for probing the mystery since the waves can detect any objects that come in their way.

In 1987, Operation Deepscan took place - the biggest SONAR exploration of Loch Ness. Boats equipped with SONAR were deployed across the whole width of the lake and they simultaneously sent out acoustic waves. BBC News reported that the scientists had made sonar contact with a large unidentified object of unusual size and strength. The researchers decided to return to the same spot and re-scan the area.

After analysing the SONAR images, it seemed to point to debris at the bottom of the lake, although three of the pictures were of moving debris. Shine speculates that they could be seals that got into the lake, since they would be of about the same magnitude as the objects detected. But no one has been able to confirm their identity.

The Surgeon's Photo: Famous picture that for a long time was considered to be the most trusted photo of the monster.

Similarly, many people have captured photos of monster-like creatures that have never been explained. Many have been dismissed as forgeries, but the most trusted one was called the Surgeon�s Photo, since it was supposed to be have been taken by well-respected surgeon Robert Wilson. For about 50 years, the true story behind the picture was a mystery, but it was finally revealed to be a hoax started by a man called Marmaduke Wetherall. Attempting to prove to the world that Nessie exists, Wetherall had already claimed to have found monster-sized footprints near the Loch, but when the casts he sent to the Natural History Museum in London were analysed, they were found to be hippopotamus tracks! As revenge, he made a model of the monster and photographed it on Loch Ness. He managed to persuade Wilson to pass it off as his own, since he knew that no one would believe him after his hippo prank.

Monster earthquakes?

Although many sightings could be hoaxes, there could also be a geological interpretation: seismic activity in the lake could cause disturbances on its surface that could be mistaken for Nessie. Loch Ness is situated on the Great Glen fault line that was created by the collision of continents that formed Scotland 400 million years ago. Over 200 years ago, a major earthquake with its epicentre in Lisbon, Portugal caused water disturbances in the Loch more than 1500 km away. �Reports state that a wave about two or three feet high was seen travelling up and down Loch Ness,� says Robert Musson, the principal seismologist at the British Geological Survey. But he claims that generally there is little seismic activity in the area and doesn�t think that earthquakes can account for the repeated sightings.

Dr Luigi Piccardi, an Italian specialist in Mediterranean geology, disagrees. Currently studying events depicted in Greek mythology, he says that many of the effects described can be related to real effects during strong earthquakes. Similarly, he thinks that the same theory applies to Nessie and claims that there are recurring tremors around the town of Inverness just 16 kms away that could spread to the Loch. He plans to test his theory by conducting a detailed seismic survey in the area.

But should geological explanations fail, psychology may be able to provide some insight. Helen Ross, a psychologist and expert on illusions, thinks that myth is so powerful that people can convince themselves that an ordinary object floating in the water is a monster. �When something really ambiguous is there, people often don�t know what they�re seeing and they can see all sorts of strange things,� she says. �It�s a bit like seeing faces in the fire or ink blots appearing as all sorts of creatures.�

Until physical evidence of the Loch Ness monster is found � like the creature itself or its skeleton � it may be hard to convince most scientists that it exists. Perhaps the sightings are simply an example of the human fascination for mystery and intrigue, and the awe that many people have for the natural world.

Siberian Mystery Blast "Solved"

The scars on the landscape can still be seen today

By BBC News Online science editor Dr David Whitehouse

Astronomers may have solved the puzzle of what it was that brought so much devastation to a remote region of Siberia almost a century ago.

The asteroid was probably a pile of space rubble - like Mathilde

In the early morning of 30 June, 1908, witnesses told of a gigantic explosion and blinding flash. Thousands of square kilometres of trees were burned and flattened.

Scientists have always suspected that an incoming comet or asteroid lay behind the event - but no impact crater was ever discovered and no expedition to the area has ever found any large fragments of an extraterrestrial object.

Now, a team of Italian researchers believe they may have the definitive answer. After combining never-before translated eyewitness accounts with seismic data and a new survey of the impact zone, the scientists say the evidence points strongly to the object being a low-density asteroid.

They even think they know from where in the sky the object came.

Completely disintegrated

"We now have a good picture of what happened," Dr Luigi Foschini, one of the expedition's leaders, told BBC News Online.

The direction of the flattened trees is a vital clue

The explosion, equivalent to 10-15 million tonnes of TNT, occurred over the Siberian forest, near a place known as Tunguska.

Only a few hunters and trappers lived in the sparsely populated region, so it is likely that nobody was killed. Had the impact occurred over a European capital, hundreds of thousands would have perished.

A flash fire burned thousands of trees near the impact site. An atmospheric shock wave circled the Earth twice. And, for two days afterwards, there was so much fine dust in the atmosphere that newspapers could be read at night by scattered light in the streets of London, 10,000 km (6,213 miles) away.

But nobody was dispatched to see what had happened as the Czars had little interest in what befell the backward Tungus people in remote central Siberia.

Soil samples

The first expedition to reach the site arrived in 1930, led by Soviet geologist L A Kulik, who was amazed at the scale of the devastation and the absence of any impact crater. Whatever the object was that came from space, it had blown up in the atmosphere and completely disintegrated.

Nearly a century later, scientists are still debating what happened at that remote spot. Was it a comet or an asteroid? Some have even speculated that it was a mini-black hole, though there is no evidence of it emerging from the other side of the Earth, as it would have done.

What is more, none of the samples of soil, wood or water recovered from the impact zone have been able to cast any light on what the Tunguska object actually was.

Researchers from several Italian universities have visited Tunguska many times in the past few years. Now, in a pulling together of their data and information from several hitherto unused sources, the scientists offer an explanation about what happened in 1908.

Possible orbits

They analysed seismic records from several Siberian monitoring stations, which combined with data on the directions of flattened trees gives information about the object's trajectory. So far, over 60,000 fallen trees have been surveyed to determine the site of the blast wave.

"We performed a detailed analysis of all the available scientific literature, including unpublished eye-witness accounts that have never been translated from the Russian," said Dr Foschini. "This allowed us to calculate the orbit of the cosmic body that crashed."

The object appears to have approached Tunguska from the southeast at about 11 km per second (7 miles a second). Using this data, the researchers were able to plot a series of possible orbits for the object.

Of the 886 valid orbits that they calculated, over 80% of them were asteroid orbits with only a minority being orbits that are associated with comets. But if it was an asteroid why did it break up completely?

"Possibly because the object was like asteroid Mathilde, which was photographed by the passing Near-Shoemaker spaceprobe in 1997. Mathilde is a rubble pile with a density very close to that of water. This would mean it could explode and fragment in the atmosphere with only the shock wave reaching the ground."

The research will be published in a forthcoming edition of the journal Astronomy and Astrophysics.

The Mystery of the Bermuda Triangle

Over the past century, hundreds of ships and planes have gone missing in a mysterious stretch of water in the Atlantic Ocean called the Bermuda Triangle. Is there a scientific explanation for these disappearances?

Five Avengers (USN Photo)

Miami, Puerto Rico and Bermuda are prime holiday destinations boasting sun, beaches and coral seas. But between these idyllic settings, there is a dark side: countless ships and planes have mysteriously gone missing in the one and a half million square miles of ocean separating them. About 60 years ago, the area was claiming about five planes every day and was nicknamed the Bermuda Triangle by a magazine in 1964. Today, about that many planes disappear in the region each year and there are a number of theories explaining what could be happening.

The Bermuda Triangle, a stretch of water between Puerto Rico, Bermuda and Florida, has been the site of many plane and ship disappearances.

Twins George and David Rothschild are among the first passengers to have experienced bizarre effects in the Bermuda Triangle. In 1952, when they were 19 years old, the two naval men had to make an emergency trip home on a navy light aircraft, north over the Florida Keys, to attend their father�s funeral. �We had been flying for probably 20 or 30 minutes when all of a sudden the pilot yelled out that the instruments were dead and he became very frantic,� says George Rothschild. He had lost his bearings, and not only did he not know where he was, he also had no idea how much gas was left in the fuel tanks. After what seemed like hours, they landed safely in Norfolk, on the Florida coast.

Some speculate that it had nothing to do with the location, but rather the instruments that were available at the time. Pilot Robert Grant says that back in the 1940s, navigating a plane involved a lot of guesswork since they relied completely on a magnetic compass to guide them. �Dead reckoning� was used, which means that pilots would trust their compass and then estimate how the wind would influence their planned flight path to remain on track. �No matter what your mind tells you, you must stay on that course,� says Grant. �If you don�t, and you start turning to wherever you think you should be going, then you�re toast.�

The landscape of the island of Bermuda is quite unique: it is a remote coral reef precariously perched on a massive extinct volcano. Fisherman Sloan Wakefield, who knows the waters of the Bermuda Triangle very well, thinks that the weather could be responsible for some of the disappearances. �Because the island is a dot in the Atlantic Ocean, it gets weather from everywhere and it can change in a heartbeat. One minute, you can be looking at good weather, and the next moment you�ve got a low front coming through,� he says. He has already seen 15 to 20 foot (4.6m to 6m) waves on the sea.

Hurricanes are common in the Bermuda Triangle area. In the Atlantic Ocean, they typically originate off the African coast and thrive off the moisture of the warm, tropical waters. Hurricane records from the past 100 years have shown that they often head west for the United States but swerve into the waters of the Bermuda Triangle at the last minute. Jim Lushine, a meteorologist at the National Hurricane Centre in Miami, Florida studies the weather in the Bermuda Triangle and says that there are more hurricanes in that particular area than in any other in the Atlantic basin.

But thunderstorms in the area can be just as dangerous. In 1986, a historic ship called the Pride of Baltimore vanished from radar screens while it was in the Bermuda Triangle, making a trip from the Caribbean to Baltimore. About four and a half days later, the wreckage and eight survivors were found and they revealed that the ship had been hit by a microburst: 80 mile per hour winds emanating from a freak thunderstorm. It happened so quickly that the crew didn�t have time to make a distress call. �The ship was sunk in the downburst, unfortunately with a great loss of life,� says Lushine. �Similar downbursts are probably responsible for some of the sunken ships in the Bermuda Triangle.�

Even more unpredictable than thunderstorms are waterspouts. These can be caused by tornadoes that move out to sea or rotating columns of air that drop from thunderstorms, creating a vortex of spray. When the moisture condenses, it forms a twisting column that connects the sea to the clouds. Jim Edds, an amateur fisherman who chases and films waterspouts for fun, says that if you are out at night and a tornado-like waterspout develops - the really big, strong ones with high velocity - it can flip your vessel over.

Bubbling methane

Seismic activity at the bottom of the ocean can also be an explanation for disappearing ships. Scientists have discovered that huge bubbles of methane gas can violently erupt without warning from the ocean floor and at least one oil rig is thought to have sunk because of this phenomenon. Ralph Richardson, the director of the Bermuda Underwater Exploration Institute, claims that a large pocket of gas could surround a ship, causing it to lose buoyancy and disappear without warning.
At the U.S. Navy�s research centre in California, Bruce Denardo, an expert in fluid dynamics, has proved that bubbles from methane gas eruptions could be responsible for vanishing ships in the open ocean. Water pressure causes objects to float, and the deeper the water, the greater the pressure exerted to keep the object floating at the surface. If bubbles from methane are introduced, they lower the density of the water. They take up space, but the volume of water stays the same, causing the buoyant force to decrease. In an experiment with a ball in water, Denardo can demonstrate that the ball sinks deeper and deeper down in water as the amount of bubbles increases, until it reaches a critical point where it sinks completely. �If a ship were to take on enough water, it would sink to the bottom and stay there,� says Denardo.

A mysterious time warp?

Others have more far out explanations for the Bermuda Triangle disappearances. Property developer Bruce Gernon claims that on December 4th 1970, when he flew from the island of Andross in the Bahamas to Florida, he experienced a distortion in space time. He had made the same trip on many occasions, but he claims that his journey that day was much faster than usual. �I noticed a huge U-shaped opening in the clouds, but as I approached it, the top of the opening closed and it became a horizontal tunnel that appeared to be 10 to 15 miles long,� he says. �When the aircraft entered the tunnel, some lines, which I call time lines, appeared which were rotating counter-clockwise. It was difficult to keep it level and concentrate on the other end of the tunnel which was aiming directly for Miami.�



Gernon claims that when he came out of the tunnel, it closed fast behind him and he was surrounded by a strange fog. His instruments had stopped working and Air Traffic Control had no radar trace of his plane � until they realized that it was actually over Miami beach. Given the time they had been flying, they should still have been about 45 minutes away from Miami. After researching what could have happened, Genon is now writing a book about his experience. �I have come to the conclusion that we experienced a space time warp of a hundred miles in thirty minutes,� he says.
Is this scientifically feasible? About 80 years ago, Einstein proposed his general theory of relativity which claimed that huge spinning objects could distort space and time in their surroundings. Although NASA researchers have now found signs that black holes and neutron stars appear to warp space time, it is still a far cry from concepts introduced by science fiction like wormholes, or tunnels in space time that provide travellers with an express route between different dimensions and great distances.
Explanations for the vanishings in the Bermuda Triangle are all still theories. But especially for people who have witnessed bizarre events in this area, there is a strong desire to find some answers. One author, Gian Quasar, has been investigating every single plane and ship disappearance in the Bermuda Triangle and has listed every case on a massive internet database at http://www.bermuda-triangle.org/. With initiatives like this and further research, perhaps the mystery will come to a conclusion.

UFO, A Mysteries Thing

What's a UFO?

Since man first started looking up into the skies he saw things he couldn't explain. For the last fifty years or so these things have taken on the label "UFOs." Originally an abbreviation for the Air Force term "Unidentified Flying Object", it has become a synonym to most people for "Alien Spaceship." For the Air Force, though, it is simply a term to refer to something in the skies that the observer can see but not recognize. Usually the explanation is less extraordinary than a flying saucer manned by visitors from other worlds. Often a weather balloon or natural phenomenon is the cause. However, there are cases on record where no good common explanation was ever found.

Ufo Mysteries: A Reporter Seeks the Truth
by Curt Sutherly

Dr. J. Allen Hynek, astronomer, foremost proponent of UFOs, and the one who came up with the expression "close encounters of the third kind," defines a UFO as:

The reported perception of an object or light seen in the sky or upon land the appearance, trajectory, and general dynamic and luminescent behaviour of which do not suggest a logical, conventional explanation and which is not only mystifying to the original percipients but remains unidentified after close scrutiny of all available evidence by persons who are technically capable of making a common sense identification, if one is possible.

What Hynek considers to be "all available evidence" may be much less than what a skeptic would require. For example, the evidence appealed to by UFOlogists consists of (1) the testimony of people who claim to have seen aliens and/or alien spacecraft; (2) facts about the type of people who give the testimony; (3) the lack of contrary testimony or physical evidence that would either explain the sighting by conventional means (weather balloon, prank, meteor shower, reflection of light, etc.) or discredit the reliability of the eyewitness; and, (4) alleged weaknesses in the arguments of skeptics against the UFOlogists. The last item is irrelevant to the issue, yet it plays a disproportionately large role in UFOlogy.

It seems reasonable to believe that the only reason we cannot explain these sightings by conventional means is because we do not have all the evidence - not because these sightings are probably due to alien visitations. If we had all the evidence, we would probably be able to explain the sightings by some conventional means. The fact that we cannot prove that Mr. and Mrs. Barney Hill were not abducted by aliens, does not support the hypothesis that they were abducted by aliens.

Many UFOlogists think that if eyewitnesses such as Whitley Strieber, Betty and Barney Hill, or other alleged alien abductees are not insane or evil, then they cannot be deluded and are to be trusted with giving accurate accounts of alien abduction. Yet, it seems obvious that most sane, good, normal people are deluded about many things and not to be trusted about certain things.

UFOlogists would rather follow their faulty logic than accept the conclusions of Project Blue Book, the U.S. Air Force report which states that "after twenty-two years of investigation...none of the unidentified objects reported and evaluated posed a threat to our national security." (It was in this Blue Book that Edward Ruppelt coined the term "UFO.") UFOlogists are unimpressed with the Condon Report, as well. Edward U. Condon was the head of a scientific research team which was contracted to the University of Colorado to examine the UFO issue. His report concluded that "nothing has come from the study of UFOs in the past 21 years that has added to scientific knowledge...further extensive study of UFOs probably cannot be justified in the expectation that science will be advanced thereby."

It is assumed by UFOlogists that the government, especially the CIA, is lying and covering up alien landings and communication. However, there is no evidence for this other than a general distrust of the government and the fact that many government officials have lied, distorted the truth and been mistaken when reporting to the general public. The CIA, however, has shown little interest in UFOs since about 1950, except to encourage UFOlogists to believe that reconnaissance flights might be alien craft. UFOlogists prefer another kind of lie to the government lie. They support the work of NBC, for example, which produced two dozen programs called "Project UFO," said to be based on Project Blue Book. However, unlike the Air Force, NBC suggested that there were documented cases of alien spacecraft sightings. The programs, produced by Jack Webb of Dragnet fame, distorted and falsified information to make the presentation look more believable. No UFOlogist took NBC to task for lying. To the skeptic, NBC was pandering to the taste of the viewing audience. Government agents lie for all sorts of reasons, but covering up alien landings does not seem to be one of them.

Most unidentified flying objects are eventually identified as hoaxes or astronomical events, aircraft, satellites, weather balloons, or other natural phenomena. In studies done by the Air Force, less than 2% of UFO sightings remain unidentifiable. It is more probable that with more information those 2% would be identified as meteors, aircraft, etc., than that they are alien spacecraft.

The reason no logical explanation seems credible to UFOlogists is probably because those making and hearing the reports either do not want to hear a logical explanation or they make little or no effort to find one. In any case, the fact that some pilots or scientists claim they cannot think of any logical explanations for some perceptual observations is hardly proof that they have observed alien spacecraft.

If They are Out There, Where?

If we do assume there is intelligent life in places other than Earth, where might they be? Though scientists last century thought the planet Mars might be a good candidate, and some even thought they detected a huge canal system stretching across the planet, recent probes sent to Mars have failed to detect even bacteria-like creatures, let alone a civilization capable of producing a flying saucer. With the rest of the planets in our solar system seemingly too hot or cold, the best hope for intelligent life seems to be across the void of interstellar space in other parts of our galaxy.

In an attempt to detect intelligent life beyond our solar system researchers have conducted a number of SETI programs trying to use radio waves to detect the existence of other civilizations. So far no SETI program has been successful in finding intelligent life, but there are millions of stars in our galaxy alone that might have planets that could harbor life and carefully looking at each one of them will take a long time.

Is there intelligent life on other planets? Have they visited us on Earth? Are some UFOs alien spaceships? Or are there other explanations for saucers in the sky? Nobody has final proof one way or another. We need to keep open eyes and open minds.

Finally, it should be noted that UFOs are usually observed by untrained skywatchers and almost never by professional or amateur astronomers, people who spend inordinate amounts of time observing the heavens above. One would think that astronomers would have spotted some of these alien craft. Perhaps the crafty aliens know that good scientists are skeptical and inquisitive. Such beings might pose a threat to the security of a story well-told.

The Lost Continent : ATLANTIS

The capital of Atlantis as described by Plato. (Copyright Lee Krystek 2006)

The idea of a lost, but highly advanced civilization has captured the interest of people for centuries. Perhaps the most compelling of these tales is the story of Atlantis. The story appears again and again in books, television shows and movies. Where did the story originate and is any of it true?

Plato's Atlantis

The story of the lost continent of Atlantis starts in 355 B.C. with the Greek philosopher Plato. Plato had planned to write a trilogy of books discussing the nature of man, the creation of the world, and the story of Atlantis, as well as other subjects. Only the first book was ever completed. The second book was abandoned part way through, and the final book was never even started.

Plato used dialogues to express his ideas. In this type of writing, the author's thoughts are explored in a series of arguments and debates between various characters in the story. Plato often used real people in his dialogues, such as his teacher, Socrates, but the words he gave them were his own.

In Plato's book, Timaeus, a character named Kritias tells an account of Atlantis that has been in his family for generations. According to the character, the story was originally told to his ancestor, Solon, by a priest during Solon's visit to Egypt.

There had been a powerful empire located to the west of the "Pillars of Hercules" (what we now call the Straight of Gibraltar) on an island in the Atlantic Ocean. The nation there had been established by Poseidon, the God of the Sea. Poseidon fathered five sets of twins on the island. The firstborn, Atlas, had the continent and the surrounding ocean named for him. Poseidon divided the land into ten sections, each to be ruled by a son, or his heirs.

The capital city of Atlantis was a marvel of architecture and engineering. The city was composed of a series of concentric walls and canals. At the very center was a hill, and on top of the hill a temple to Poseidon. Inside was a gold statue of the God of the Sea showing him driving six winged horses.

About 9000 years before the time of Plato, after the people of Atlantis became corrupt and greedy, the gods decided to destroy them. A violent earthquake shook the land, giant waves rolled over the shores, and the island sank into the sea, never to be seen again.

So, is the story of Atlantis just a fable used by Plato to make a point? Or is there some reason to think he was referring to a real place? Well, at numerous points in the dialogues, Plato's characters refer to the story of Atlantis as "genuine history" and it being within "the realm of fact." Plato also seems to put into the story a lot of detail about Atlantis that would be unnecessary if he had intended to use it only as a literary device.

On the other hand according to the writings of the historian Strabo, Plato's student Aristotle remarked that Atlantis was simply created by Plato to illustrate a point. Unfortunately, Aristotle's writings on this subject, which might have cleared the mystery up, have been lost eons ago.

Location, Location, Location

If we make the assumption that Atlantis was a real place, it seems logical that it could be found west of the Straight of Gibraltar near the Azores Islands. In 1882 a man named Ignatius Donnelly published a book titled Atlantis, the Antediluvian World. Donnelly, an American politician, had come to the belief that Plato's story represented actual historical fact. He located Atlantis in the middle of the Atlantic Ocean, suggesting the Azores Islands represented what remained of the highest mountain peaks. Donnelly said he had studied zoology and geology and had come to the conclusion that civilization itself had begun with the Atlantians and had spread out throughout the world as the Atlantians established colonies in places like ancient Egypt and Peru. Donnelly's book became a world-wide best seller, but researchers could not take Donnelly's theories seriously as he offered no proof for his ideas.

As time when on it became obvious that Donnelly's theories were faulty. Modern scientific surveys of the bottom of the Atlantic Ocean shows it is covered with a blanket of sediment that must have taken millions of years to accumulate. There is no sign of a sunken island continent.

Are there any other candidates for the location of Atlantis? People have made cases for places as diverse as Switzerland, in the middle of Europe, and New Zealand, in the Pacific Ocean. The explorer, Percy Fawcett, thought that it might be located in Brazil. One of the most convincing arguments, though, came from K.T. Frost, a professor of history at the Queen's University in Belfast. Later, Spyridon Marinatos, an archaeologist, and A.G. Galanopoulos, a seismologist, added evidence to Frost's ideas.

The Minoan Connection

Frost suggested that instead of being west of the Pillars of Hercules, Atlantis was east. He also thought that the catastrophic end of the island had come not 9000 years before Plato's time, but only 900. If this was true, the land of Atlantis might already be a well-known place even in Plato's time: the island of Crete.

Crete is now a part of modern Greece and lies just south of Athens across part of the Mediterranean Sea. Before 1500 B.C. it was the seat of the Minoan Empire. The Minoans dominated the eastern Mediterranean with a powerful navy and probably extracted tribute from other surrounding nations. Archaeological excavations have shown that Minoan Crete was probably one of the most sophisticated cultures of its time. It had splendid architecture and art. A code of laws gave women equal legal status to men. Agriculture was highly developed and an extensive irrigation system existed.

Then, seemingly in a blink of an eye, the Minoan Civilization disappeared. Geological studies have shown that on an island we now know as Santorinas, located just ten miles to the north of Crete, a disaster occurred that was very capable of toppling the Minoan state.

Santorinas today is a lush Mediterranean paradise consisting of several islands in a ring shape. Twenty-five hundred years ago, though, it was a single large island with a volcano in the center. The volcano blew itself apart in a massive explosion around 1500 B.C.

To understand the effect of such an explosion, scientists have compared it with the most powerful volcanic explosion in historic times. This occurred on the Island of Krakatoa in 1883. There a giant wave, or tsunami, 120 feet high raced across the sea and hit neighboring islands, killing 36,000 people. Ash thrown up into the air blackened the skies for three days. The sound of the explosion was heard as far away as 3,000 miles.

The explosion at Santorinas was four times as powerful as Krakatoa.

The tsunami that hit Crete must have traveled inland for over half a mile, destroying any coastal towns or cities. The great Minoan fleet of ships were all sunk in a few seconds. Overnight the powerful Minoan Empire was crushed and Crete changed to a political backwater. One can hardly imagine a catastrophe more like Plato's description of Atlantis' fate than the destruction of Crete.

Many of the details of the Atlantis story fit with what is now known about Crete. Women had a relatively high political status, both cultures were peaceful, and both enjoyed the unusual sport of ritualistic bullfighting (where an unarmed man wrestled and jumped over a bull).

If the fall of the Minoans is the story of Atlantis, how did Plato get the location and time wrong? Galanopoulos suggested there was a mistake during translation of some of the figures from Egyptian to Greek and an extra zero added. This would mean 900 years ago became 9000, and the distance from Egypt to "Atlantis" went from 250 miles to 2,500. If this is true, Plato (knowing the layout of the Mediterranean Sea) would have been forced to assume the location of the island continent to be squarely in the Atlantic Ocean.

Not everyone accepts the Minoan Crete theory of the story of Atlantis, but until a convincing case can be made for some other place, it, perhaps, remains science's best guess.

Mystery The Curse of Tutankhamun

Death Shall Come on Swift Wings To Him Who Disturbs the Peace of the King... -Supposedly engraved on the exterior of King Tutankhamen's Tomb

The king was only nineteen when he died, perhaps murdered by his enemies. His tomb, in comparison with his contemporaries, was modest. After his death, his successors made an attempt to expunge his memory by removing his name from all the official records. Even those carved in stone. As it turns out, his enemy's efforts only ensured his eventual fame. His name was Tutankhamen: King Tut.

The ancient Egyptians revered their Pharaohs as Gods. Upon their deaths the King's bodies were carefully preserved by embalming. The mummified corpses were interned in elaborate tombs (like the Great Pyramid) and surrounded with all the riches the royals would need in the next life. The tombs were then carefully sealed. Egypt's best architects designed the structures to resist thieves. In some cases heavy, hard-granite plugs were used to block passageways. In others, false doorways and hidden rooms were designed to fool intruders. Finally, in a few cases, a curse was placed on the entrance.

Most of these precautions failed. In ancient times grave robbers found their way into the tombs. They unsealed the doors, chiseled their way around the plugs and found the secrets of the hidden rooms. They stripped the dead Kings of their valuables. We will never know if any of the thieves suffered the wrath of a curse.

Archaeologists from Europe became very interested in Egypt in the 19th century. They uncovered the old tombs and explored their deep recesses always hoping to find that one forgotten crypt that had not been plundered in antiquity. They knew that the Pharaohs had been buried with untold treasures that would be of immense artistic, scientific, and monetary value. Always the archaeologists were disappointed.

The Search for the Missing King

In 1891 a young Englishman named Howard Carter arrived in Egypt. Over the years he became convinced that there was at least one undiscovered tomb. That of the almost unknown King Tutankhamen. Carter found a backer for his tomb search in the wealthy Lord Carnarvon. For five years Carter dug looking for the missing Pharaoh and found nothing.

Carter and Carnarvon

Carnarvon summonded Carter to England in1922 to tell him he was was calling off the search. Carter managed to talk the lord into supporting him for one more season of digging. Returning to Egypt the archaeologist brought with him a yellow canary.

A Few Authentic Curses from Mummy Tombs As for anybody who shall enter this tomb in his impurity: I shall ring his neck as a bird's. As for any man who shall destroy these, it is the god Thoth who shall destroy him. As for him who shall destroy this inscription: He shall not reach his home. He shall not embrace his children. He shall not see success.

"A golden bird!" Carter's foreman, Reis Ahmed, exclaimed. "It will lead us to the tomb!"

Perhaps it did. On November 4th, 1922 Carter's workmen discovered a step cut into the rock that had been hidden by debris left over from the building of the tomb of Ramesses IV.. Digging further they found fifteen more leading to an ancient doorway that appeared to be still sealed. On the doorway was the name Tutankhamen.

When Carter arrived home that night his servant met him at the door. In his hand he clutched a few yellow feathers. His eyes large with fear, he reported that the canary had been killed by a cobra. Carter, a practical man, told the servant to make sure the snake was out of the house. The man grabbed Carter by the sleeve.

"The pharaoh's serpent ate the bird because it led us to the hidden tomb! You must not disturb the tomb!"

Scoffing at such superstitious nonsense, Carter sent the man home.

Carter immediately sent a telegram to Carnarvon in England and waited anxiously for his arrival. Carnarvon made it to Egypt by November 26th and watched as Carter made a hole in the door. Carter leaned in, holding a candle, to take a look. Behind him Lord Carnarvon asked, "Can you see anything?"

Carter answered, "Yes, wonderful things."

The day the tomb was opened was one of joy and celebration for all those involved. Nobody seemed to be concerned about any curse. Rumors later circulated that Carter had found a tablet with the curse inscribed on it, but hid it immediately so it would not alarm his workers. Carter denied doing so.

The tomb was intact and contained an amazing collection of treasures including a stone sarcophagus. The sarcophagus contained three gold coffins nested within each other. Inside the final one was the mummy of the boy-king, Pharaoh Tutankhamen.

The Curse Strikes?

A few months after the tomb's opening tragedy struck. Lord Carnarvon, 57, was taken ill and rushed to Cairo. He died a few days later. The exact cause of death was not known, but it seemed to be from an infection started by an insect bite. Legend has it that when he died there was a short power failure and all the lights throughout Cairo went out. His son reported that back on his estate in England his favorite dog howled and suddenly dropped dead.

Even more strange, when the mummy of Tutankhamun was unwrapped in 1925, it was found to have a wound on the left cheek in the same exact position as the insect bite on Carnarvon that lead to his death.

By 1929 eleven people connected with the discovery of the Tomb had died early and of unnatural causes. This included two of Carnarvon's relatives, Carter's personal secretary, Richard Bethell, and Bethell's father, Lord Westbury. Westbury killed himself by jumping from a building. He left a note that read, "I really cannot stand any more horrors and hardly see what good I am going to do here, so I am making my exit."

Outside the tomb before it was opened.

What horrors did Westbury refer to?

The press followed the deaths carefully attributing each new one to the "Mummy's Curse" By 1935 they had credited 21 victims to King Tut. Was there really a curse? Or was it all just the ravings of a sensational press?

Herbert E. Winlock, the director of the Metropolitan Museum of Art in New York City, made his own calculations about the effectiveness of the curse. According to to Winlock's figures of the 22 people present when the tomb was opened in 1922, only 6 had died by 1934. Of the 22 people present at the opening of the sarcophagus in 1924, only 2 died in the following ten years. Also ten people were there when the mummy was unwrapped in 1925, and all survived until at least 1934.

In 2002 a medicine scholar at Monash University in Melbourne, Australia, named Mark Nelson, completed a study which purportedly showed that the curse of King Tut never really existed. Nelson selected 44 Westerners in Egypt at the time the tomb was discovered. Of those, twenty-five of the group were people potentially exposed to the curse either because they were at the breaking of the sacred seals in the tomb, or at the opening of the sarcophagus, or at the opening of the coffins, or the unwrapping of the mummy. The study showed that these exposures had no effect on the length of their survival when compared to those not exposed.

Perhaps, the power of a curse is in the mind of the person who believes in it. Howard Carter, the man who actually opened the tomb, never believed in the curse and lived to a reasonably old age of 66 before dying of entirely natural causes.

A Rational Explaination?

Several people have suggested that illnesses associated with the ancient Egyptian tombs may have a rational explanation based in biology. Dr. Ezzeddin Taha, of Cairo University, examined the health records of museum workers and noticed that many of them had been exposed to Aspergillus niger, a fungus that causes fever, fatigue and rashes. He suggested that the fungus might have been able to survive in the tombs for thousands of years and then was picked up by archaeologists when they entered.

Dr. Nicola Di Paolo, a Italian physician identified another possible fungus, Aspergillus ochraceus, at Egyptian archaeological sites suggesting it might also have made visitors to the tomb, or even those that just handled artifacts from the tombs, sick. Aspergillus ochraceus has not been shown to be fatal, however.

In 1999 a German microbiologist, Gotthard Kramer, from the University of Leipzig, analyzed 40 mummies and identified several potentially dangerous mold spores on each. Mold spores are tough and can survive thousands of years even in a dark, dry tomb. Although most are harmless, a few can be toxic.

Kramer thinks that when tombs were first opened and fresh air gusted inside, these spores could have been blown up into the air. "When spores enter the body through the nose, mouth or eye mucous membranes, " he adds, "they can lead to organ failure or even death, particularly in individuals with weakened immune systems."

For this reason archaeologists now wear protective gear (such as masks and gloves) when unwrapping a mummy, something explorers from the days of Howard Carter and Lord Carnarvon didn't do.

So was the curse of the mummy a mold spore named Aspergillus flavus or Cephalosporium? Or was it all media hype? Or is there another explaination?
