It turns out there are no undiscovered chambers hidden behind the walls of King Tutankhamun’s tomb in the Valley of the Kings. National Geographic has a story about a recent effort to use radar to find theoretical hidden chambers that might have housed the mummy of Queen Nefertiti. This was a third test after two previous tests were inconclusive, but this time they mean it. In a statement, Egypt’s Supreme Council of Antiquities said, “We conclude, with a very high level of confidence, that the hypothesis concerning the existence of hidden chambers adjacent [to] Tutankhamun’s tomb is not supported by the GPR data.” Which is a bummer. NatGeo‘s story goes into much more detail (with lots of cool pics), and is a very good read.
