Astronomical orientation of the Egyptian pyramids and the real age of the Old Kingdom (no replies)

I am pleased to offer to the forum participants my new study regarding the astronomical orientation of the Egyptian pyramids. The study of the ancient ritual of "stretching of the cord" reveals a comprehensive astronomical synchronism, which explains the orientation of all measured pyramids of the Old Kingdom from the 3rd to 5th dynasty inclusively and ultimately leads to the conclusion that the theory of the orientation of the pyramids to the true north is incorrect and that the age of the Old Kingdom epoch is underestimated in currently accepted Egyptian chronology.

Here is the link to the paper: Egyptian starry tales. Part I: "Stretching of the cord" ceremony for aligning Old Kingdom pyramids

Any questions on the subject matter of the study are welcome.
