The massive capital City of Angkor [aka Yaśodharapura, City of Yasovarman I (or Yasodhara?), with more than one million inhabitants in ancient times], the seat of the great Khmer Empire in Southeast Asia for 500 years, was once the biggest city in the world.

Khmer Empire (Wiki)

For centuries, this incredible civilization flourished, building the largest religious monument on Earth, Angkor Wat (one square kilometer wat "Angkor Temple"), and mastering urban engineering in a challenging landscape. But then it was mysteriously abandoned, swallowed by the jungle.

Now, cutting-edge technology and new discoveries are finally revealing how this astounding empire rose to global prominence – and what likely led to its devastating collapse.

Follow a scientific detective story that is challenging everything we thought we knew about this ancient Buddhist-Hindu metropolis.

Did Ancient Egyptians use Helicopters and Jets?

Pravda

There is a scientific theory that says that Egyptians descended from Martians who had once visited this planet

It was even before Christ that Greeks took a keen interest in the culture and history of people living on the banks of the Nile River. In 1848, one of numerous archaeological expeditions working in Egypt discovered strange hieroglyphs at the height of about ten meters [30 ft] right above the entrance to the Seti Temple in Abydos. The walls were covered with the strange signs that greatly puzzled researchers. The only thing the researchers realized at once was that they had discovered some images of strange mechanisms that nobody ever saw before.

It is still unknown what exactly an artist living about 3,000 years ago engraved on the walls. The archaeological expedition carefully copied the mysterious signs on the temple walls, and the hieroglyphs gave rise to endless disputes and heated debates among Egyptologists.

As a result, a majority of Egyptologists arrived at a conclusion that there were just four strange objects drawn in different variations. Unfortunately, researchers of the 19th century failed to understand what ancient Egyptians actually drew on the temple walls. Like any sensation the mysterious Abydos hieroglyphs were absolutely forgotten some time later.

In about 150 years, the respectable Arab newspaper Al-Sharq Al-Awsat published several sensational photos taken in the Amon Ra Temple in Karnak. At that, the newspaper asked its readers whether they believed that ancient Egyptians knew about battle aviation. The question would have seriously puzzled readers under some different conditions. But the photos the newspaper published demonstrated the bas-reliefs of an ancient temple built under Seti I, who ruled 3,000 years ago.

And on the bas-reliefs an ancient artist engraved a battle helicopter with a distinct rotor and a tail unit. Nearby, the artist depicted several other aircrafts astonishingly resembling contemporary supersonic fighters and heavy strategic bombers!

After the sensational publication of the photos it became clear why Egyptologists of the 19th century could not tell what was depicted on the walls of the temple in Abydos. Indeed, the researchers did not know how helicopters and aircrafts look. More>>
