Why Isn’t the Great Pyramid Bigger?
Sometimes if you turn a question around, it helps you understand the entirety of the topic at hand.
The most common question regarding the Great Pyramid is How did they construct it?
Far less often asked are questions like Why did they build it? and Why did they make it so big?
I’m aware of quite a few books that attempt to explain how it was built. And others that provide unorthodox explanations for the Great Pyramid’s purpose, such as The Giza Power Plant. I’m not aware of any books that provide an orthodox explanation for why the pyramids were built. I’ve not even seen a chapter that tries to explain why it needed to be so big. Sure, big is important – grandeur for a leader. But a quarter as big would still be awesome, and easier to achieve.
- Lack of labor
- Lack of time
- Structural limitations
- There was a specific purpose that required a certain size
Regarding the latter, if you read a book about building nuclear bunkers, it will explain the relationship between wall thickness, wall composition and protection from radiation.
Example from The Nuclear Survival Handbook (pages 95-96):
2.2 inches of concrete halves the radiation from fallout, and 6 inches of it does the same to initial gamma radiation… if we double any given thickness, we more than double the protection from radiation.
Now I’m not suggesting that ancient Egypt was under threat of nuclear warfare (although ancient Indian texts do describe just that), and I’m not suggesting that the Egyptians could have discovered or even theorized cosmic rays – but I find this interesting, about protecting astronauts from cosmic radiation, via Wikipedia:
For passive mass shielding, the required amount could be too heavy to be affordably lifted into space without changes in economics (like hypothetical non-rocket space launch or usage of extraterrestrial resources) — many hundreds of metric tons for a reasonably-sized crew compartment. For instance, a NASA design study for an ambitious large spacestation envisioned 4 metric tons per square meter of shielding to drop radiation exposure to 2.5 mSv annually (+/- a factor of 2 uncertainty).
Now the base of the Great Pyramid covers 52,900 m² (230 metres x 230 meters). And it is estimated that the entire structure weighs 5.9 million metric tons. So that’s just over 100 metric tons per square meter, from the base.
I’m not going to get into chamber positions, meters of granite above them, comparing the shielding proficiency of granite versus silicon dioxide (as NASA proposes), or the levels of protection aimed for. But I do presume the following statement is true:
The only proposal for walls that are anything like the thickness of the walls of the Great Pyramid, was by NASA for protection from cosmic rays.
Or, the only thing I can think of that needs to be buried deep underground to work is a Proton Decay Detector. Could the pyramid have been a laboratory?
It might have been easier convincing your people to build a grand pyramid than an underground laboratory…

I believe the answer to your question (why didnt they build a bigger pyramid)is that there was a specific purpose that required it to be exactly the size it is. A study of ” sacred geometry” and universally significant numbers reveals that the Great Pyramid encodes all of those ratios and numbers. Its purpose was to encapsulate the entirety of human knowledge about the design of the universe in general and our planet/ solar system in particular.Its secondary purpose was to preserve that information and communicate it to future generations, such as ourselves, who may, as in our case, have forgotten those universal laws. If it was even slightly smaller or larger than it is, then it would not be fit for purpose. For a full explanation and to be blown away, see this essay

I guess I am quite confused,I always believed the pyramids were
built by Hebrew slaves and the massive stones moved by rolling them
on logs,why were they built,I still say EGO. Whether the meglomaniac
that prompted these magnificent structures was from another world is
left to speculation.My personal belief is we are all some part alien
and I say this because there does not seem to be any link between
neanderthal and modern man.
I agree that it was built as a monument to the knowledge of it’s builders, and as a record of that knowledge for use of future generations. The perimeter of the base records not one, but 3 different lengths of the year, depending on how it is measured. Also, the ratio of the area of one side to the height is exactly the same as the area of 1/8th of a sphere to the radius. In effect, the Egyptians had not only “squared” a circle, but had “cubed” a sphere. But why that exact size? I read once that the pyramid units were based on 1/2 of the polar axis divided by 10 million. So the base in these pyramid units is 365.242 units.
