Despite the great strides made by scientists in the interpretation of puzzling and mysterious phenomena, there are still many discoveries and phenomena that they can not explain.
Here are five of the most important phenomena that science has not found any explanation to this day :
1 - Hum Taos The Hum :
A small town in Mexico called Taos hears the sound of a hum on the horizon similar to the sound of diesel engines. The strange thing about this sound is that it can be easily heard by the human ear, while it is impossible to record it with any microphone or any sound recording device. They can not hear the sound. This voice is called Bahamah Taos. Until this hour, scientists could not determine its source.
2 - Nazca Lines :
The Nazca lines in the southern desert of Peru cover an area of 190 square miles, thought to belong to the people of the Nazca, 2,000 years ago. It is still as clear and magnificent as yesterday, and scholars have questioned the accuracy of drawing on such a vast space as a painting by a giant artist. How did the distances and dimensions of this accuracy be controlled since 2000 years, and they do not possess industrial satellites or drawing tools that are used today? No one has been able to reach any answer so far.
3 - Sailing Rocks :
At the bottom of the dry lake in the valley of death, stones weighing an estimated 400 kg without any external force slip mysteriously on the surface of the earth. Some scientists believe it is a set of events and natural phenomena such as wind and ice. While others question this theory when they point out that these stones do not follow an expected course, they change their course abruptly
4 - Spontaneous human combustion :
In Florida, US police found the widow Mary Reiser in her apartment completely burnt, leaving only small parts of her body, while the household utensils in the kitchen were completely fused. In the loss of his life, but the abnormal here is that experts estimated the enormous temperature that the old lady was exposed to about 1500 degrees Celsius, a degree can never produce Every natural from a normal thermal source at home, this degree of heat used to melt iron and minerals, and are often used in designated burning waste of major industrial companies Maharkaldkhmh! This phenomenon is called self-combustion and has not been explained to this day.
5 - Voice of record from the soles of the Pacific:
In 1997, a powerful sound from the depths of the Pacific, echoed by 5,000 miles, was picked up by the Voice Recorder of the National Oceanic and Atmospheric Administration of the Deep Sea, where it was heard 5,000 kilometers away. Although the sound was very similar to those of some of the living, but no animal is yet able to sound so loud, even the blue whale known to produce the highest frequency on Earth.
The administration has not been able to determine the actual source of the sound, so this phenomenon remains unexplained to this moment.
