A while back, we  decided to talk about some of very interesting mysteries that have yet to be deciphered by scientists, in an article entitled “Most Fascinating Mysteries of the World -part 1-“. We could not leave it at that, especially considering that there are so many, other mysteries, waiting to be uncovered by humankind. We give to you four other mysteries of the world, which you may, or may not have heard of, but which will definitely catch your interest. So without further ado, we give to you, the sequel to our first post, and one which we hope, will make you want to learn even more about the inexplicable phenomena that occurred throughout history, and also in modern times.

1. Mary Celeste 

According to stories, Mary Celeste was a brigantine ship, which was discovered in December 1872 in the Atlantic Ocean. Nothing unusual up until now, right? Wrong. The ship was found without a crew, but in perfect working condition. One year later, two boats were discovered in Spanish waters. The first had a body of a man with an american soldier, and the other one held seven dead bodies in it. Legend has it that the boat was cursed, because the captain died after no more than one day on board of it.

Mary Celeste’s story is the greatest mystery in the history of the Navy. Some say that it was nothing more than a pirate ship, while others prefer to believe in fantastic explanations. The first name of the ship was Amazon, and it was apparently involved in a series of accidents. In the end it became property of some Scottish folk during 1860-1870. In the end, the ship was claimed by Americans for the price of 3000 dollars. Since then, its crew and captain where nowhere to be found, and 130 years later, people still do not understand why.

2. Jack the Ripper 

There have been so many movies and stories about Jack the Ripper that it is almost impossible to discern truth from fiction. What we know for sure is that during 1888, London was terrorized by Jack the Ripper, who was apparently a serial killer from Whitechapel. The name was first used, after the murderer sent a letter to the press, which he signed under this name. All of Jack’s victims were prostitutes. They would usually be found with their throats cut open, and bodies mutilated.

The horrid thing about this case is that, in most situations, the bodies were left to be found only minutes after their death. It was speculated that prince Albert Victor was behind the murders, but not enough evidence was gathered during that time to fuel a conviction. Investigations started again in modern times, but they still did not manage to shed some light on the case.

3. Tao Hum 

Apparently, Tao Hum is a humming sound which can be sensed in quiet areas, where people experiment a sensation similar to the sound of a Diesel motor-cycle. It is basically an annoying sound that people hear when they sit in silence for too long, and we are positive you have also experienced it. There is nothing horrid or jaw-dropping about this mystery, but the truth is that scientists have no idea why so many people experience it.

In areas where it was first encountered, specialists found no trace of eletromagnetic waves, or sound signals that might explain the symptoms, of Tao Hum, which usually included nausea, dizziness, or headaches. In 1994, a study was conducted on people susceptible to this sound, but no conclusion was drawn. Similarly, in 2005, there was an attempt to record the sounds on an aparatus, but they still didn’t understand what exactly it is. We may never know.

4. The Zodiac Murderer

Since we have already discussed about one of the most popular bloody mysteries of the world, why not continue our list, with a similar case, that of the Zodiac murderer? This particular individual has also inspired many bloody movies. According to stories, the Zodiac murderer operated in California, for 10 months, during the 1960′s. His first two victims were shot near Benecia, and the next two near Vallejo. One of the victims miraculously escaped even if she/he was shot in the neck and head. Nearly an hour after that crime, the police received a call in which the criminal confessed to his crimes. One month later, three letters reached the press. The deciphered messages sounded something like this:

I like killing people because it is very entertaining, it is more fun than killing wild animals in forests because man is the most dangerous animal of all to kill. It is even better than when you have sex with a girl. The best part is when I die, and I will be reborn in paradise and those who have killed will become my slaves. I will not tell you my name because you will try to slow down or I stop my collecting of slaves for the afterlife”

 

Some of his messages were never deciphered, while others held valuable information about the Zodiac Killer’s next victims. The only suspect that the police had was Arthur Leigh Allen, but there was not enough evidence to convict him. To this day, authorities do not know who the zodiac Killer is. Talk about fascinating mysteries of the world.
