  Why did Nobel-prize winner Luis Alvarez not find the chamber in the Pyramid?

+ 2 like - 0 dislike

In the 1960s, Luis Alvarez and his team used muons to search for voids in the Egyptian pyramids.

See Search for Hidden Chambers in the Pyramids by L. Alvarez et al.

He was adamant that there were no chambers - also when asked privately.

Why did other people find a chamber now, in 2017, with the same method? Did the authors comment on the older paper?

Alvarez did not check the Khufu pyramid, but the Kephren , using cosmic muons. The paper is peer reviewed and will be published in Nature. In this preview of the paper to be published

"Here we follow in the footsteps of Alvarez et al.who used spark chambers as muon detectors in Khafre's pyramid (Kephren) and concluded that there is no unknown structure with a volume similar to the King’s chamber above the Belzoni chamber"
