Pyramid with spare room …

Credited to the #ScansPyramid project, the discovery of a "new" (as in old but previously unknown) corridor (measuring 9x2m) above the main entrance of the #GreatPyramid in #Giza has been announced earlier today:

Egypt unveils newly discovered chamber inside Great Pyramid

CAIRO (AP) — Egypt’s antiquities authorities on Thursday unveiled a newly discovered, sealed-off chamber inside one of the Great Pyramids at Giza, just outside of Cairo, that dates back some 4,500 years ago.

Important find in the Cheops pyramid of Giza

An international research team has discovered a previously unknown chamber in the Cheops pyramid of Giza. As early as 2016 measurements had given reason to assume the existence of a hidden hollow space in the vicinity of the chevron blocks over the entrance. Now scientists from the Technical University of Munich (TUM) have used ultrasound and endoscopy to make an important contribution to confirming this assumption. The status of the Egyptian pyramid as one of the best investigated structures in the world makes this find particularly important.

A cavity of sorts there has been noted earlier already, cf. K. Morishima et al. in @nature 552 (2017). 🔐💵

Discovery of a big void in Khufu’s Pyramid by observation of cosmic-ray muons - Nature

Cosmic-ray muon radiography has been used to non-invasively visualize the voids in the Great Pyramid (Khufu’s Pyramid), revealing a large void situated above the Grand Gallery.

And before anyone gets too excited about "secret chambers" - its much more likely that this tunnel is more of a "construction aid", like remains of a ramp or relief cavity ... which actually is not less exciting! How they built it? Well, this is how. 😲🙌

Precise characterization of a corridor-shaped structure in Khufu’s Pyramid by observation of cosmic-ray muons - Nature Communications

Khufu’s Pyramid is one of the largest archaeological monuments in the world, and still contains unexplored voids. Here, the authors use cosmic-ray muon radiography in multiple positions to precisely characterize one of these inner structures called the North Face Corridor.

Want to see that endoscope glimpse into that "new" #GreatPyramid corridor? Of course you want to see that endoscope glimpse into the Great Pyramid chamber. 😉
