There are situations in the world that even today are impossible to understand. What were those days like many years ago, what gigantic structures of such a size and weight that today's machines couldn't support, how enormous buildings were constructed, the delicate workmanship of stone, and much more. We list 10 mysterious things that baffle scientists and generate even today...
Immortal Stone Set
300-ton limestone blocks were used to build a 9-metre-high embankment surrounding the Inca castle in Peru's Cusco region for 360 metres, but no mortar was used.
The Secret of the Hammer
This hammer, found in Texas in 1936, is estimated to be 500 million years old. Scientists are amazed by how this primitive tool, consisting of a wooden hammer and an iron head, fit inside a stone block and by the purity of the iron in the head.
Ancestor of Concord
This object, believed to have been made in 200 BC, was found in a tomb in Egypt in 1898. In 1972, an archaeologist suggested that the object was a model airplane with superior aerodynamics.
Landing track for UFOs
These motifs on the coast of the Pampa in Peru depict the forms of ancient plants and animals. It is believed that these motifs, created by the Nazca civilization, served as landing strips for aliens to land on Earth.
A city built 1000 years ago
The ancient city of Nan Madol, located near an island in the Pacific Ocean, took nearly 1,000 years to build. Construction began in 200 BC. 100 artificial islands were connected by ordering blocks weighing 250 million tons each. How these giant basalt blocks arrived there remains a mystery.
Aluminum belt buckle
A belt buckle found in the tomb of the Chinese general Zhou, who is estimated to have died in 300 AD, is made of aluminum at 85%. It's worth noting that the tomb was opened in 1956. In the 19th century, it became possible for the first time to separate aluminum, which occurs in nature only as a compound, from other substances and use it as a separate substance.
Mysterious Skull
This Mayan crystal head, believed to be 1,000 years old, was carved from a single block. If the light shines from beneath the crystal skull, how it was made at that time remains a mystery; the captured light exits directly from the eye holes. Even the technology available in this field today doesn't allow this.
Antique computer
In 1900, the Antikythera mechanism was found in a shipwreck on the Greek island of Crete. An examination revealed that the object had been used to calculate the positions of the Moon, Sun, and planets.
2000-year-old battery
A 2,000-year-old battery discovered in Baghdad in 1938 stunned the scientific world. Upon examination, the battery was found to consist of a copper cylinder installed in a 13-centimeter clay pot, an iron rod surrounding it, and asphalt covering the mouth of the clay pot. This object, considered the oldest battery in the world, was found to produce 2 volts of energy.
Map of the Future
A map drawn by the famous Turkish navigator Piri Reis in 1513, showing Africa, America, and the South Pole, generated great interest when it appeared in 1929. The South Pole was discovered in 1818. Even more intriguing, Piri Reis showed coastal areas of the continent that were covered in ice. However, the ice on the continent had melted 6,000 years before the map was drawn.
