FROM NUN TO THE STARS HYPOTHESIS - The Ladder to the Sky Inside the Great Pyramid — Pyramid Texts, Utterance 572

The interior of the Great Pyramid of Giza has never yielded a mummy, an inscription, or grave goods in any of its three main chambers. Four features of that interior resist explanation under conventional funerary models. The Subterranean Chamber was cut thirty metres into bedrock and abandoned unfinished while the pyramid above was completed to final dimensions — no other Old Kingdom pyramid replicates it. The Grand Gallery, forty-seven metres of corbelled ascending passage, has no parallel in scale or function. The four stellar shafts were sealed at both ends during construction, ruling out ventilation, and point at specific stars at the historical moment the pyramid was built. And the voids and corridors found by muon radiography and robotic survey in 2017, 2023 and 2025 have no funerary analogue in any documented pyramid. This paper proposes that the interior is a vertical cosmological universe in three registers — Nun below, the earthly realm between, the stellar apex above — with the Grand Gallery as the axis of ascent. Four independently dated evidence streams converge on that reading. The Pyramid Texts of Unas organise their inscription programme spatially to match the stages of the journey. Khnum — the god named in Khufu's own birth name — appears in that corpus solely as the maker of the means of ascent: the ferryboat, the ladder, and the body of the king. The Dendera lunar panel sets out a fourteen-station sequence with the same vertical structure. And the Osiris Shaft at Giza is a physical Nun chamber on the site itself, its lowest level recorded by its excavator as an island surrounded by water. Seven falsifiable predictions follow. Several can be tested by work already under way — including the sealed corridor announced inside the Great Pyramid in November 2025, whose contents remain undisclosed. This paper registers its interpretation of that corridor before the reveal, as a prediction rather than a claim. The paper does not assert that intentional cosmological design has been proven. It sets out a reading and the evidence that would refute it. Notes: About this work. I am not an academic, a scientist, or a specialist in any field, and no one funds or sponsors this research. I do it because the questions interest me. These papers are not submitted for peer review, and that is a deliberate choice rather than an avoidance of scrutiny. Peer review certifies a text at a moment in time; this work is built to keep changing as evidence arrives. Every paper in the series is revised when new findings warrant it, each revision is deposited with a DOI, and the earlier versions stay public so the changes can be read against each other. Several arguments here have already been rewritten, and one was withdrawn entirely, because a source did not hold up. What I ask instead is direct correction. Every claim is cited, every citation is checkable, and every prediction states what would refute it. If something is wrong, the fastest route to fixing it is to tell me — and it will be fixed in the next version, with the change recorded.
