Great pyramid dimensions 640x480.jpg

The measurements of the Great Pyramid of Cheops have been meticulously scrutinized over the recent centuries. The remains for the footers of now missing encasement were used to extrapolate the original outer measurements of 440 Royal Cubits of the sides of the square base (within nine inches of perfectly square), and a height of 280 Royal Cubits.

The Egyptian royal cubit

The earliest attested standard measure is from the Old Kingdom pyramids of Egypt and was called the royal cubit (mahe). The royal cubit was 523 to 525 mm (20.6 to 20.64 inches) in length[3], and was subdivided into 7 palms of 4 digits (4 fingers) each, for a 28-part measure in total. Secure evidence for the royal cubit unit is known from Old Kingdom architecture, from at least as early as the construction of the Step Pyramid of Djoser from around 2,700 B.C.[4]

Old Egyptian geometers could calculate the square root of two from the value of the hypotenuse of a cubit. This well-attested old Egyptian unit was known as the "construction remen" and used a good approximation: 2 × 20 ÷ 28 ~= √2.

Face angle from horizontal

"Each triangular face intersects the ground at an angle of arcsin(sqrt(PHI)/PHI), a little less than 52 degrees." –Tony Smith, Great Golden Pyramid

Trigonometrically, the angle, θ, is the arcsin[1] of the ratio of the Great Pyramid face length over the height of the pyramid converted to degrees:

Θ = arcsin(280/356) * 360/2π = 51.8612° (1)

Cubing the Sphere

The builders of the Great Pyramid of Cheops placed the height at less than one Royal Cubit error to the value of the square perimeter circumference, 440 X 4 = 1760 cubits.

The ancient Egyptians are assumed to have approximated pi (3.1415926...) as the value of 22/7 (3.1428571...). This is only an error of 0.001 from the actual value of pi.

Visually, when illustrated with pi or 22/7, the difference is undetectable.

Proportions in Square Roots

An illustration of the Great Pyramid showing Golden Ratio proportions as multiples of roots, by Christian Lange

As exemplified by Christian Lange, as noted from a site in German on Schaumberger's implossion vortex science, when the center to the side of the pyramid base is used as one unit, the proportions of the dimensions of the Great Pyramid at Giza[2] are expressed as square roots of two, four, Phi, Phi+1, and Phi+2.

Phi = 1.6180339887...

The base of the pyramid is square (within 9 inches).

  • Square root of one
    • The center of the square base to the center of a side is 220 Royal Cubits = 220 / 220 = 1 = Sqrt(1)
  • Square root of two
    • The center of the square base to a corner is Sqrt(2) (Pythagoras Theorem)
  • Square root of four
    • The base side is Sqrt( (1+1)^2 ) = Sqrt(4) (Pythagoras Theorem)
  • Square root of Phi
    • The ratio of 1/2 of the base (220) to the height (280) is 1.2727272727...
      The actual Sqrt(Phi) = 1.2720196495, a difference of 0.0007076232, or 0.16 cubits error at the scale of the Great Pyramid.
  • Square root of Phi+1
    • The face length is 356 / 220 = 1.61818... ~ Sqrt(Phi + 1)
    • Deviation is 1.6181818181 - Sqrt(Phi+1) = 0.0001478294, or 0.03 cubits
  • Square root of Phi+2
    • The edge length is 418 / 220 = 1.90 ~ Sqrt(Phi + 2)
    • Deviation is 1.90 - 1.9021130325 = 0.0021130325, or 0.46 cubits

Golden Hyperbolic Orbit

Draft Page

Be as it may, the angle of the Great Pyramid's face is 52.84°. This is the only angle that will intersect a hyperbolic cone and produce an egg-shaped orbit that has a length to width ratio of Φ, the Golden Ratio. All orbits that are less than perfectly circular are a section of a hyperbolic cone with the orbital path more curved near the Sun, like the small end of an egg, and less curved at the distant side of the orbit.

Alternate Overview

Pyramid Matrix, by Carl P. Munck

Welcome to Atlantis, Lemuria or former technological civilizations are mere myths? Is there a way to know? There is incontrovertible evidence of precise global positioning, thousands of years ago, requiring space age technologies, and satellite triangulation. Carl Munck, [[archaeocryptography}archaeocryptographer]], introduces an ancient Pyramid Matrix, in which monuments - across the globe - encode their exact positions with respect to latitude and longitude. The science of decoding these monuments is called archaeocryptography. For latitude, ancient monuments were referenced to the same (modern) equator. For longitude, these monuments were referenced to a former Giza, Egypt Prime Meridian - discovered by Munck - that ran from pole to pole across the Great Pyramid. This Web site provides introductory examples of ancient monuments, how they encode their positions in the Matrix, and resources for deeper study (and verification).
My Discovery of Archaeocryptography
Hello, I'm Carl Munck. I once had a hobby. Cryptography. But it's not a hobby anymore! Back in 1978 I was trying to develop a code system to be based on the language of latitude and longitude (degrees, minutes and seconds), the idea being to multiply the three numbers in each set to a single number, viz., 15 degrees times 15 minutes times 0l.6000 seconds products at 360 (the number of degrees of arc in any circle).


Dan Winter Paraphrasing Egyptian Lore

AMENTI as Harmonic Implosion Bubble for Genepools... The Only Way Home?
“The bible was merely a frail distortion of the Sumerian/Egyptian, which came from the Annunaki bloodlines.
The original pyramid was designed as a Harmonic Resonance Chamber, through which multidimensional frequency bands could be pulled in from deep space and from the planetary core of Sirius B, using a great ankh positioned directly below a crystalline cap stone. Through the power of the ankh a tremendous amount of UHF energy was pulled into focus within the cap stone of the pyramid, then pro- jected downward through the structure into the second-dimensional frequency bands. The pyramid and Arc of the Covenant were situated upon Earth's geographical center point, within the energy vortex that represented the "Heart Chakra" within Earth's planetary bio-energetic system. This vortex allowed energy exchange to take place between Earth and the fourth-dimensional frequency bands. By creating a Harmonic Resonance Chamber within such an interdimensional vortex, the D-2 over- tones of HU-1 could be combined with the base tones of D-4/HU-2, forming an interdimensional resonant tone through which visiting craft traveling from Sirius B and other star systems could enter and leap through time, making transit to Earth almost instantaneous. The Great Pyramid was created to allow immediate inter- vention of the Sirian Council and Galactic Federation fleets should the Arc of the Covenant come under Anunnaki Resistance attack. While the pyramid was in operation as an interstellar teleport station, it served as the greatest deterrent to the Annunaki Resisance invasion. The Great Pyramid was used as an active interstellar transport station from the time of its construction 48,459 years ago to about 30,000 years ago (about 28,000 BC) when an explosion in Atlantis caused Earth to tile slightly on its axis, knocking the pyramid's 4-D vortex (Earth's heart chakra) out of its previous alignment with the vortex systems of Sirius B and several other planetary systems to which it had been originally aligned. ET visitation was commonplace in Egypt prior to this misalignment of the Earth's grid, but following this event, transit from other star systems required more time and resources, so visitation became much less frequent.
