Many strange and unexplained events have occurred in modern history. These events are often based around an unsolved murder, bizarre landmark, unexplained attack, or archeological discovery. This list will be examining some bizarre locations and unsolved mysteries.
10. Why do dogs jump off the Overtoun Bridge?
The Overtoun Bridge is an arch bridge located near Milton, Scotland, over the Overtoun Burn. A burn is a term used to describe a type of stream which is smaller than a river. Milton is a village in West Dunbartonshire, which is just on the outskirts of Dumbarton. The Overtoun Bridge has gained public attention because of the unusually large number of dogs that have allegedly leaped to their deaths off the bridge. It is not known exactly when or why dogs began to leap from the bridge, but news stories and studies have indicated that these deaths might have begun during the 1950s or 1960s, at the rate of about one dog a month. The long leap from the bridge onto the waterfalls of the Overtoun Estate almost always results in immediate death. Inexplicably, some dogs have actually survived, recuperated, and then returned to the site to jump again. These dogs are known to the locals of Dumbarton as “second timers.” The dogs have mostly jumped from one side of the bridge, during clear weather, and have mostly been breeds with long noses. No explanation has yet been found. There have been a number of theories as to why dogs are choosing to end their lives by jumping off the bridge, ranging from the bridge being haunted to the canines suffering from depression, or even picking up depressed or suicidal feelings from the bridge. However, the explanation which seems to be the most logical involves the presence of minks on the banks of the burn. The mink�s powerful anal glands leave marks wherever they go and the strong musty smell they produce is of interest to dogs. It has been suggested that the height of the bridge�s granite walls significantly impairs the dogs� sense of sight and hearing, so when they go to investigate the smell, they are unaware of the massive fall that awaits them. However, this explanation doesn�t satisfy all. It is still puzzling why the dogs all jump from roughly the same spot or why they return for a second jump if initially unsuccessful. There is something quite eerie about this bridge.
9. Why are the songs of blue whales getting steadily deeper each year?
In the 1960s a group a marine biologists planted microphones in the world�s oceans to record the songs of blue whales. The scientists were conducting studies on the whale�s behavior. Over time it has been discovered that blue whales aren�t singing the same way they used to. The largest animals on earth are singing in ever-deeper voices each year. The scientific community is baffled by this occurrence. The abnormality was first noticed eight years ago, when scientists kept needing to recalibrate the automated song detectors used to track blue whales off the California coast. The detectors are triggered by songs that match a particular waveform. Lately, the detectors have to be reset annually. Researchers have gathered thousands of blue whale recordings made since the 1960s, spanning populations from the North Atlantic, to the South Pacific, to the East Indian Ocean. Their analysis, published in October in Endangered Species Research, shows that the songs� tonal frequency is falling every year by a few fractions of a hertz. It is the same all over the world. Among the suggested explanations include ocean noise pollution, changing population dynamics, and new mating strategies. Another explanation involves the recovery of blue whale populations, which were nearly hunted to extinction during the first half of the last century. Because only male blue whales sing, the answer may involve sexual selection. The situation remains a mystery.
8. Who murdered Dwight Dixon?
On April 29, 2008, a man named Dwight Dixon got into an altercation withMarvin Harrison outside of the West Thomas Street car wash in hiladelphia. Marvin Harrison is one of the most prolific receivers in NFL history, playing 13 seasons for the Indianapolis Colts. During his playing career Marvin came across as a quiet fellow, rarely talking or celebrating after any one of his 128 touchdowns. A different side of Harrison was revealed on April 29. Dwight Dixon returned to his vehicle after having an rgument with Harrison when the shooting began. Dixon turned around to allegedly find Marvin Harrison double fisted firing two guns at him. Dixon managed to drive away, but all the windows on his car were blown out and he was hit in the hand. Dixon claims his truck was riddled with bullets. A man named Robert Nixon so claims he saw Harrison shooting at Dixon. Robert Nixon sued Marvin Harrison after one of the bullets fired was lodged in his back. In the spring of 2009 Dwight Dixon gave an interview to the ESPN program E:60 claiming that Harrison was the man that shot him. A few months later on July 21, 2009, Dwight Dixon was shot and killed in the Fairmount section of Philadelphia. A gunman approached the driver’s side of his Toyota Camry and fired four times through the back window and then fired three more times into the passenger side window and door. Dwight Dixon was shot 7 times. Moments after the shooting, Dixon told police that he believed the incident was related to an April 2008 assault in the same neighborhood, in which his truck was sprayed with gunfire and he suffered a bullet hole in his left hand. Dwight Dixon fell into a coma shortly after the shooting and died a few months later. Dwight Dixon�s murder remains unsolved. Philadelphia police have enlisted the FBI to help investigate whether the fatal shooting of Dixon is related to an earlier incident in which the victim claimed that he was shot
6. What is the function of the UVB-76 transmitter in Povarovo, Russia?
UVB-76 is the callsign of a shortwave radio station that usually broadcasts on the frequency 4625 kHz (AM full carrier). The station is known among radio listeners by the nickname The Buzzer. It features a short, monotonous buzz tone, repeating at a rate of approximately 25 tones per minute, for 24 hours per day. The station has been observed since around 1982. In rare occasions, the buzzer signal is interrupted and a voice transmission in Russian takes place. Only three to four such events have been noted. The station briefly changed to a higher tone of longer duration on January 16, 2003, although it has since reverted to the previous tone pattern. Frequently, distant conversations and other background noises can be heard behind the buzzer, this suggests that the buzzing device is behind a live and constantly open microphone. The station’s transmitter is located at Povarovo, Russia, which is about halfway between Zelenograd and Solnechnogorsk and 40 kilometres northwest of Moscow. The location and call sign were unknown until the first voice broadcast of 1997. The actual purpose of this station remains unknown. One website claims the station is meant to “Transmit orders to the military units and recruitment centers of the Moscow military district.” Because of the nature of the broadcast and the fact that its transmitter location is rumoured to be a communications hub of the General Staff of the army, UVB-76 is widely believed to be used to transmit encoded messages to spies, as is generally assumed for the many numbers stations that populate shortwave frequencies.
5. Where did the Baigong Pipes come from?
The Baigong Pipes are a series of pipe-like features found on and near Mount Baigong, about 40 km southwest of the city of Delingha, China. The pipes are reported to be associated with a “pyramid” about 50 to 60 meters high that was built on Mount Baigong. There are three mysterious triangular openings on top of a mountain containing hundreds of ancient rusty iron pipes of unknown origin. Some of the pipes go deep into the mountain. Some of them go into a nearby salt water lake. Some of the larger pipes are 40 cm in diameter, are of uniform size, and are placed in what seems like purposeful patterns. Associated with these pipe-like features are “rusty scraps” and “strangely shaped stones,� analysis of the “rusty scraps” reportedly found that they consist of 30% ferric oxide and large amounts of silicon dioxide and calcium oxide. Archaeologists have dated the pipes to a time far before people casted iron. This has caused many people to identify the Baigong pipes as an out of place artifact. The true nature of these pipe formations remains a complete mystery. Oddly, the pipes are still clean of debris. Certain websites have claimed the pipes to be an ancient astronomy lab or even spacecraft launching site left by extraterrestrials. They reference the fact that the pipes contain a proportion of silica close to what occurs on Mars. The pipes were first discovered by a group of scientists from the United States who were seeking dinosaur fossils. They reported the pipes to local authorities in Delingha. However, the pipes were ignored until a report by Ye Zhou appeared in the Henan Dahe Bao.
4. What are the Baghdad Batteries?
In 1936, while excavating ruins of a 2000-year-old village near Baghdad, workers discovered a mysterious small vase. It was a 6-inch-high pot of bright yellow clay, which dated back two millennia. The pot contained a cylinder of sheet-copper 5 inches by 1.5 inches. The edge of the copper cylinder was soldered with a 60-40 lead-tin alloy comparable to today’s solder. The bottom of the cylinder was capped with a crimped-in copper disk and sealed with bitumen or asphalt. Another insulating layer of asphalt sealed the top and also held in place an iron rod suspended into the center of the copper cylinder. The rod showed evidence of having been corroded with an acidic agent. In 1940, Wilhelm K�nig published a paper speculating that the artifacts may have been galvanic cells, perhaps used for electroplating gold onto silver objects. This interpretation continues to be considered a hypothetical possibility by the scientific community. If correct, the artifacts would predate Alessandro Volta’s 1800 invention of the electrochemical cell by more than a millennium. In 1940, Willard F.M. Gray, an engineer at the General Electric High Volatage Laboratory in Pittsfield, Massachusetts, made a replica of the battery. Using copper sulfate solution, it generated about half a volt of electricity. In 1970s, German Egyptologist, Arne Eggebrecht built a replica of the Baghdad battery and filled it with freshly pressed grape juice, as he speculated the ancients might have done. The replica generated 0.87V. He used current from the battery to electroplate a silver statuette with gold. Skeptical archaeologists see the electrical experiments as embodying a key problem with experimental archaeology; such experiments can only show that something was physically possible, they say nothing about whether it actually occurred. After much argument, the Baghdad Batteries remain a mystery.
3. What was The Bloop?
The Bloop is the name given to an ultra-low frequency and extremely� powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) several times during the summer of 1997. The sound was traced to a remote point in the South Pacific Ocean west of the southern tip of South America. According to the NOAA description, the sound came rapidly in frequency over about one minute and was of sufficient amplitude to be heard on multiple sensors, at a range of over 5,000 km. The NOAA’s system ruled out any known man-made sound, such as a submarine or bomb, or familiar geological sounds such as volcanoes or earthquakes. The audio profile of the Bloop resembles that of a living creature. The system identified it as unknown because it was several times louder than the loudest known biological sound. In history, five other significant unexplained sounds have been named by NOAA: Julia, Train, Slowdown, Whistle, and Upsweep. Cryptozoologists have speculated that the Bloop could have been the sound of a giant sea monster, several times bigger than the largest known living creature. Others have suggested that it could have been bubbles from some kind of huge chemical reaction in the seabed or have something to do with the interaction of powerful ocean currents. The Bloop remains a mystery of the deep ocean. The system that recorded the Bloop is a military relic of the Cold War. In the 1960s the U.S. Navy set up an array of underwater microphones, or hydrophones, around the globe to track Soviet submarines. The network was known as the Sound Surveillance System. The listening stations are located hundreds of yards below the ocean surface, at a depth where sound waves become trapped in a layer of water known as the “deep sound channel.� Here temperature and pressure cause sound waves to keep travelling without being scattered by the ocean surface or bottom. Most of the sounds detected come from whales, ships or earthquakes, but some noises have proved baffling.
2. Who developed the Antikythera Mechanism?
The Antikythera Mechanism is a device that was recovered in 1901 from the Antikythera wreck. The Antikythera wreck is a shipwreck that was discovered by sponge divers off the coast of the Greek island, Antikythera. The mechanism remained a complete mystery for decades until the scientific community became interested and the Antikythera Mechanism Research Project was formed. The mechanism dates from around the end of the 2nd century B.C. and is the most sophisticated mechanism known from the ancient world. Nothing as complex was invented for the next thousand years. The Antikythera Mechanism is now understood to have been dedicated to calculating astronomical positions. It operated as a complex mechanical “computer”, which tracked the cycles of the Solar System. It is the first known mechanical computer. This artifact is being studied by some of the best scientists in the world, who routinely make new discoveries. Many elements of the design remain a mystery. Recent experiments have revealed surprising results on the back dials of the Antikythera Mechanism, including a dial dedicated to the four- year Olympiad Cycle of athletic games in ancient Greece. The research team has also deciphered all the months on the mechanism�s 19-year calendar, revealing month names that are of Corinthian origin, probably from a Corinthian colony of the western Hellenic world. The Antikythera Mechanism is one of the greatest archaeological discovery of the 20th century. It has revolutionized the knowledge surrounding the history of science and technology during the Hellenistic Age.
1. What caused the W32 Nimda virus?
In the months before and after September 11, 2001, the United States was bombarded with cyber attacks. In July of 2001, a worm was observed on computers running Microsoft’s IIS (Internet Information Services) web server. The worm spread using a common type of vulnerability known as a buffer overflow. It did this by using a long string of the repeated character ‘N’ to overflow a buffer, allowing the worm to execute arbitrary code and infect the machine. On July 19, 2001, the amount of infected hosts reached over 350,000 zombies. It was discovered by U.S. intelligence that a coordinated attack was being made against the U.S. Governments servers. At a specific time all of the infected computers were going to send multiple pings towards the U.S. Governments server, which could cause grave damage. The plan was discovered and the servers were successfully shut down during the attack. In August of 2001, a second computer worm was released on the internet. It received the name Code Red II. The original worm tried to infect computers at random, Code Red II tried to infect machines on the same subnet as the infected machine. The source of these computer viruses remains a mystery. Nimda is a computer worm and file infector. The virus attacked the United States operating systems on September 18, 2001. Due to the release date, exactly 1 week after the attacks on the World Trade Center and Pentagon, some media quickly began speculating a link between the virus and Al Qaeda, though this theory ended up proving unfounded. Multiple propagation vectors allowed Nimda to become the Internet�s most widespread virus/worm within 22 minutes. The worm ripped through the American financial sector, causing over $3 billion in damage. It raddled the internet and is one of the worst internet viruses in history. Nimda was rarely mentioned in the mainstream media. The attackers took advantage of the chaos occurring in the U.S. during September 2001. Nimda was so effective partially because it, unlike other infamous malware like the Morris worm or Code Red used five different infection vectors. The vectors infected computers via e-mail, via open network shares, via infected websites, via exploitation, and via back doors left behind by the Code Red II. This would imply that the previous Cod Red viruses were casing and preparing for the release of the Nimda virus. It just so happened that the largest terrorist attack in U.S. history fell in line with the cyber warfare. Moonlight Maze is the U.S. government’s designation given to a series of alleged coordinated attacks on American computer systems in 1999. The Pentagon accidently discovered a pattern of probing and cyber espionage. The attackers had a sophisticated monitoring system and hackers stole large amounts of information. The attacks were traced to a mainframe computer in Moscow, but it is not known if that is where they originated. It was claimed that the hackers had obtained large stores of data that might include classified naval codes and information on missile guidance systems. The coordinated attacks remain a complete mystery. You won�t find much detailed information on the FBI�s Moonlight Maze investigation.
