The skeptical expert went to the secret room hidden in King Tut's tomb

Technical experts believe that ground-penetrating radar equipment cannot distinguish between artificial and natural voids, creating the possibility of a secret room in King Tut's grave.

The International Business Times reported that the second sweep of King Tutankhamun's grave took place on March 31, amid many skeptical comments in the tomb containing a secret room. According to the Egyptian Ministry of Antiquities' announcement at the beginning of March, the first scan was carried out by the Japanese radar expert Hirokatsu Watanabe to reveal the possibility of two rooms in the pharaoh's tomb.

However, other experts expressed much skepticism before this announcement. Many radar technicians who did not participate in the excavation project pointed out that the tomb consists of natural hollow spaces and radar equipment that are not advanced enough to distinguish between archaeological and natural features.

"Transnational radar data seems to be untreated, or unusual points are hard to see in raw data , " said Lawrence Conyers, a professor of anthropology at Denver University.

Like other experts, Conyers urged the Egyptian authorities to publish more raw data from the scan for review. Factors such as radar speed and scanning range will be helpful in determining how large the space behind the grave wall.

The second scan is to answer all doubts and reinforce Watanabe's findings. Scanning data was announced today by Egyptian Minister of Antiquities Mamdouh el-Damaty. If it is possible to draw a final conclusion, a panel of scientific and archaeological experts will be established, to conduct the excavation of the tomb by the least damaging method.
