Theory about King Tut's tomb suddenly in doubt

Archaeologists in Egypt are at odds over the popular theory that two secret burial chambers are hidden in the walls of King Tutankhamun's tomb.

The theory was first proposed by British Egyptologist Nicholas Reeves, suggesting the tomb might actually be the burial place of Queen Nefertiti.

Those claims became more popular in March when Egypt's then-Antiquities Minister Mamdouh al-Damaty told reporters scans had revealed metal and organic masses, likely indicating that the room contained funerary items.

But at a conference in Cairo this weekend, al-Damaty's successor revealed that a new radar scan came to a contradictory conclusion. According to National Geographic, Khaled El-Enany told reporters, "Until now, we don't have a conclusive result."

El-Enany has been adamant that no drilling will be allowed at the site until researchers are 100 percent sure there is a cavity behind the wall. He added that further examination of the tomb will continue by radar scan and other high-tech methods.

While some researchers have criticized the scientific methods used to scan the tomb, Reeves defended his initial theory. According to CBS he said, "I was looking for the evidence that would tell me that my initial reading was wrong. But I didn't find any evidence to suggest that. I just found more and more indicators that there is something extra going on in Tutankhamun's tomb."
