The world we live in is full of mysteries. Many odd and unfathomable things have been observed on earth. While with modern technology and research, some of the things which were once considered mysterious have been explained properly by giving logical or scientific explanations. But there are still many things in this wonderful planet — man made or natural — which human beings have not been able to explain, as yet. We researched an amazing list of Top 10 Unsolved Mysteries of the World. This list includes the mysteries which have baffled human mind for ages, but still remain unsolved.

10. Lost Inca Gold

Lost Inca Gold

The Inca civilization arose in the highlands of ancient Peru in the 13th century. The lived in that area and conquered many other areas of South America, until their conquest by the Spaniards began in the 16th century. This is where the legend of the lost gold begins. Atahualpa was an Inca king who was captured in Peru by Spanish commander Francisco Pizarro. Pizarro demanded a ransom of a roomful of gold for the king’s release. He went back on his words and had the king put to death before the last and largest part of the ransom had been delivered. This ransom gold was then buried in a secret mountain cave, where it is supposed to be present ever since! A map to this cave is also present, thanks to Valverd. He was a man who came 50 years after the king’s death. He is supposed to have become rich when his Indian bride’s family led him to that gold. This man wrote the way to that cave before dying. Is the gold still present in a cave? or was it ever there in the first place? These questions have not yet been answered!

9. The Egyptian Pyramids

The Egyptian Pyramids are the massive pyramidal monuments built by the Pharaohs. They have a square broad base and four slanting triangular sides, rising to a point. Many pyramids are present in Egypt, but no one knows exactly why they were built? Was it just built to show the might of the kings? Or did it have any religious backgrounds, i.e, something related to their sun god Ra, some people suggest that the pyramid’s shape is thought to have symbolized the sun’s rays. Well for centuries, people have theorized how these pyramids were built, but no one can tell anything for certain. It is one of those mysteries which will most probably never be solved!

This pillar is also known as Ashokan pillar and is present in Delhi, India. It was made in about 912 BCE. It is 7 m high. This pillar is of great interest to people because of the fact that it is extremely resistant to corrosion. Weathering and harsh, alternating dry and wet conditions do not affect this pillar. It does not even rust. This is because of its curious chemical metallic nature. Its metal is supposed to have many impurities, which impart this amazing quality to this pillar.

The force that helps them move is not certain and is currently under research. These rocks leave behind trails, which are usually present in all directions, as they can move in all directions. These rocks usually move only every two or three years and most tracks develop over three or four years. It is a really curious natural phenomenon.
