In this world, there are a number of mysteries that we do not understand. One of these is the great pyramid in Egypt. People speculate endlessly about who built it. How could people so long ago have been able to quarry around 2 million stones using crude tools? How could they have cut the stones so accurately? How did they move the massive stones into place without the modern equipment we have today?

What was the purpose of the pyramid? Was this a place to entomb dead royalty? Was this a place to communicate with beings from outer space? Was it some sort of massive power generator? Other buildings in Egypt have writing all over them. Why is there no writing on the pyramid to give us any information about these things? Was the Great pyramid built before Noah’s flood? We know that there are tunnels under the pyramid area, but why won’t they show us what is in these tunnels? It seems that the experts want to hide something.

So when studying the Great Pyramid, we are left with a big bag of questions and not much else. One thing we do know for certain are the dimensions of the edifice, and when you take a close look, they reveal something fascinating.

Much of the information in the following points comes from an article titled “The Great Pyramid and the Speed of Light” from the World Mysteries Blog:

- When you divide the length of the sloped side from the middle of the base to the tip by the length of half the base you get the great constant Phi, 1.618, which is the golden ratio.
- Two times the length of the base divided by the height equals the number pi.
- The length of two sides of the base is equal to the distance the earth rotates in one second. From this we can easily calculate the circumference and diameter of the earth.
- You can draw a circle inscribed by the base of the pyramid and another circle superscribed (going through the outside corners) and then find the difference in circumference. Then take that and multiply by the length of one side x 10
^{6}. This will yield the speed of light which is 299,792,458 meters/second. Just to emphasize that this is no coincidence, the Great pyramid is located at 29.9792458 degrees North latitude which is the exact same numbers.

So doesn’t it seem that the geometry of Great Pyramid reveals that pi, the golden ratio, the speed of light, the speed of earth’s rotation, and earth’s diameter are all related? These numbers have all been described elegantly by the dimensions and shape of the pyramid.

One might marvel at how intelligent the designers of the pyramid were to be able to figure these things out and encode it into a shape. How could the pyramid builders have known all this so long ago? Is it this advanced knowledge woven into its design that makes the pyramid great?

I have come to believe that those who marvel at the greatness of the Great Pyramid and the skill and cleverness of its builders totally miss the point. Let’s focus on the dimensions of the base of the pyramid. The base of the pyramid reveals the speed of light which is a foundational measurement in the universe. The base also reveals the speed of earth’s rotation. We know that mankind had nothing to do with establishing either of these things. Mankind did not decide the speed of light. Mankind did not set the earth in motion. Do you really think that these two precise speeds could be just a random thing resulting from the big bang? Calculate the odds. If the big bang didn’t do it, then how did this outcome happen?

We must conclude that the Great Pyramid is a monument to the landmark numbers of creation. The One God Who designed and built all of creation, and Who set it in motion is truly great. It was He who spoke and said “Let there be light” thus setting its pace. It was He who on the very first day set the length of a day by rotating the earth at a precise speed. The pyramid with nothing to say but what can be measured, shouts glory to God!
