Some of them have been solved with modern technology and research, but there are many manmade and natural things which are still unexplainable and wear that mystery cap. Here are the 10 such mysteries which gives a kick to human brain and modern technology.
1. Sailing stones
Sailing stones are also known as sliding rocks and moving rocks. It all refers to a geological phenomenon where rocks move in long tracks along a smooth valley floor without human or animal involvement.
They have been recorded and studied in a number of places around Racetrack Playa, Death Valley, where the number and length of travel grooves are notable. The force behind their movement is not confirmed and is the subject of research.
2. Iron pillar of Delhi

It is 7.5 meter tall, weighs approximately 6.5 tonnes and is made up of 98 percent wrought iron of pure quality. The pillar is extremely resistant to corrosion and still now it is in the open air.

Till date no one has ever come back from this place. Many researchers have been done and also have many scientific theories done regarding the disappearance in this place, but nothing is for sure.
