This is a book about a major discovery made by AIP Director Larry Pahl. The Great Pyramid passages reveal the speed of light in their measurements!
 
It is certainly an awkward and unusual claim that the numbers which form the speed of light, 299,792,458 (meters per second in a vacuum) can be derived by attention to the measures of the passages of the Great Pyramid. I can find nowhere in the body of literature on the Great Pyramid, including the writing of those known pejoratively by many Egyptologists as “pyramidologists”, where this claim is advanced. But this is indeed the claim advanced in this book.
 
This thesis is aided first, by the fact that if the 9 digits in the speed of light in meters per second, 299792458, are divided to form the following five numbers: 29, 97, 92, 45 and 8 then they match the lengths, in meters, of each one of the traditional and well known passages and chambers of the Pyramid. None are left out. And secondly these five numbers follow a rational sequence as they are started in the lowest part of the Pyramid and follow a sequential path upward. 
 
While others have posited the finding of the modern speed of light constant in various ways in the Great Pyramid (see Appendix), this is not what prompted the current inquiry. Science smiles at, but allows, the story of Isaac Newton sitting under an apple tree in his garden at Woolsthorpe Manor and somehow being inspired to theorize about the nature of gravity from the event of an apple falling from that tree.
 
The current inquiry was begun when an engineer, Bob Crielly, an associate of the American Institute for Pyramid Research, had a dream of the Great Pyramid passage lengths producing the numbers found in the speed of light. This was the apple falling from the tree for me.
 
I went to the best measures of the Great Pyramid passages I could find and began to see if the numbers in the speed of light were somehow tucked away in the Great Pyramid passages.
