I couldnt actually find a link to the study about this. All I kept finding was some studys about a L shaped ground feature in a cemetery near the pyramids. They think it may be some kind of entrance into something bigger.

I found a reddit thread and stealing this users comment.

Did a little digging because I thought this was interesting.

So this appears to be the the intro to the physical press release they did here:

And this was when they announced they would be doing a press release about a month ago:

There currently doesn’t seem to be much online thats in English and the full press release wasn’t released as a video either. Basically the reports created by the invited press is probably the best we’re getting for now but it does seem to be genuine. Looks like we’ll have to wait

No proof its genuine yet, but it could be. I dont think it would be surprising if true actually.

Rumors have existed for a long time of such a thing.

The existence of such an underground library was referenced by Herodotus, who said in Histories’, Book, II, 148:

“This I have actually seen, a work beyond words. For if anyone put together the buildings of the Greeks and display of their labors, they would seem lesser in both effort and expense to this labyrinth … Even the pyramids are beyond words, and each was equal to many and mighty works of the Greeks. Yet the labyrinth surpasses even the pyramids.”

Cant miss a chance to bring up edgar cayce either, the kentucky prophet. My dad believed this guy was the real deal, as he had diagnosed hundreds of peoples health conditions.

If you asked those from the Association for Research and Enlightenment, a multi-million-dollar organization in Virginia Beach in the United States, they would likely direct you to the teachings and prophecies of Edgar Cayce, an American psychic. Cayce prophesied the Hall of Records would be discovered and opened between 1996 and 1998, connected to the second coming of Christ.

Among Cayce’s purported prophecies is that an Atlantean flying vehicle is buried under the Sphinx and was used to build the Great Pyramid, as well as travel underground tunnels to habitable areas of inner Earth. Other architectural wonders have also been mentioned in the prophecies, including Mayan temples and the holy mountains of Tibet.

Cayce made many references in his prophecies to the hall’s location under the Sphinx: “another in the place of the records that leadeth from the Sphinx to the hall of records, in the Egyptian land,” “It lies between — or along that entrance from the Sphinx to the temple — or the pyramid; in a pyramid, of course, of its own.” and “for the preservation of the data, that as yet to be found from the chambers of the way between the Sphinx and the pyramid of records.”

Who knows lmao. But it certainly captivates the imagination.
