Semi-related, the Great Pyramid was also scanned using muon radiography, by which a "big void" was discovered [0]. Muons can penetrate through a lot of material, so they can see through very large, thick things like the pyramids. Muon tomography was also used to scan the Fukushima reactors [1] and see where the fuel ended up. [0] https://arxiv.org/pdf/1711.01576.pdf [1] https://www.world-nuclear-news.org/RS-Muons-sug…

Looks like that gear is still there (in the bedrock chamber) scanning. The 3D tour mentions it.

Is a car only a car once somebody drives it?

Does a thing sorta car-shaped without wheels count as a car? This thing never even had a lid. (You could call it a car, I guess... Rectangular, and you can sit in it.) Many people hope a legitimate sarcophagus, with an actual mummy in, might yet be found.

At which point of building a car separate parts become a car? And during maintenance (lets say engine replacement) is a car still a car? I'd say it is if meant to be used as a car again.

It looks like all the other sarcophagi found in other Old Kingdom tombs. So no, "box" isn't specific enough.

"Other"? But is it really a tomb at all? Wasn't the word "cenotaph" invented for things like it?

Of course it's a tomb. You have the mortuary temple out in front of it, with texts telling you exactly what it is. It fits in stylistically with mastabas, step pyramids, and true pyramids that come before and after that are unquestionably tombs.

Old Kingdom mummies don't tend to survive, probably due to a combination of their extreme age, the still-developing mummification process, how uncommon mummification was in that period, and that mummified bodies were targets for looting given the precious objects that could be found on them and in their wrappings. That a sarcophagus is empty that has been open since time immemorial in a tomb that has been known to be looted in antiquity is utterly unsurprising.

Wild. I was speculating about this in 2003 on my blog. Very interesting news. https://javarants.com/deconstructing-the-pyramids-76081876b3...

I thought this was going to be a conspiracy theory, but it was an interesting read about a simple (yet intriguing) idea. Thank you for sharing. As a side note, what's the blog architecture? I seem to remember seeing an XML error when I hit a link that does not exist (like at [1]) but I can't remember where :). [1] https://javarants.com/hn-error

Just Cloudfront and an S3 bucket.

It’s a power station, have a read of ‘The Giza Power Plant’

I enjoy reading far out theories like these. I recently[1] saw one that claimed all the weird tunnels that terminate just short of the outside resemble wave guides, the big tunnel with the grooves was a low pass filter and the whole structure was basically a giant antenna Any electrical engineers around feel like modelling it seeing how true it is?

You wouldn't make an inverted-inverted-V antenna out of waveguide. The whole point of waveguide is to be a transmission line, not a radiating element. Even if we ignore that, a dipole antenna of those dimensions is two orders of magnitude larger than what you'd use to radiate on the hydrogen line.

My takeaways: - From the entrance, all the way to the Grand Gallery ... it doesn't not feel like that was an intended entrance path. It gives the vibe of an auxiliary tunnel (not main path). - It's extremely "industrial". For what historians claim to be a monument, there's not a single hieroglyphic that I saw. It was the opposite of being ornate or lavish. - There's numerous deep groves intended to guide something la…

Understand that the inside of pyramids were supposed to be sealed up for eternity, not visited by people. Visitors would instead go to the mortuary temples in front of the pyramids, which indeed had ornate interiors and plenty of hieroglyphs. With the fifth dynasty pyramid of Unas, parts of what was presumably a funeral liturgy began to be inscribed on the inside of tombs for the benefit of the dead. This idea that these early, looted (and thus, empty) pyramids aren't tombs because they don't have writings inside is as silly as objecting that modern yet-to-be-filled burial vaults aren't burial vaults because they don't contain excerpts from the funeral liturgy from the Book of Common prayer on the inside. The writings on the outside tell you exactly what they are.

Tomb robbers have not generally been given to making off with sarcophagus lids.

Tomb robbers are given to smashing anything that gets in their way.

Smashing is one thing, carting off is wholly another.
