from the pyramids of Giza to the tombs of Luxor, ancient Egyptian monuments have been hidden among their features a lot of secrets for thousands of years.
Experts now believe they are about to find a "hidden secret" in the Great Pyramid of Giza.
The researchers used infrared thermal, in addition to many other techniques to learn the secrets of the "hidden chamber" and the date they were sculpted.
The "ScanPyramids" project was launched to study the pyramid, known as Cheops , which is 146 meters high and was the world's tallest man-made structure in nearly 4,000 years.

The chemical test still requires small samples, but the advanced techniques that have come into use will not cause damage or damage to the old effects, the researchers said.
Researchers also use tools that look for charged particles to help date the age of archaeological sculpture.

Queen Nefertiti
It is noteworthy that some archaeologists use advanced technology, to locate the burial place of the mythical Queen, Nefertiti.
Nefertiti, King Akhenaten's wife, remains a great mystery to scientists.
