Just took another look of different drawings of the Great Pyramid as returned by google searches. To me right now it looks like the Pyramid may have many functions of which one could be interstellar communication. For that to happen in full duplex real time you need a steady source of light for using entangled photons that are put out naturally by a star and the only one could be Polaris. A source that could send entangled photons in space of which some would reach Earth and some would reach the other planet you want to establish communication with, possibly even in our solar system. Separating those photons from others could be the job of the shape of the shafts.
About that i wrote here but don't know how accurate and really don't want to read it again cause i'm too tired. http://georgesblogforfriends.blogspot.com/2014/11/interstellar-communications-through.html
There are others inquiring about what the pyramids are and what they were designed to do.

I could spend probably the rest of my life thinking of the purpose of this pyramid. Or i could get lucky and figure it right away. One thing is obvious from the first look at the pictures. The thing has been engineered according to plans done by scientists.
Just remembered. The diode that is at the foundation of all devices we use today to communicate on the internet, the predecessor and a component of every transistor is accomplishing its function at the separation surface between two geometrical zone of doped silicone. (and again a mental block by its name).
Back to pyramid. What is the main shaft doing actually? Separating photons that may be entangled with some going to a different planet, from all the others, storing them, retrieving the information and using it to modulate or even maintain the ionosphere or do other things on Earth?
Stabilize the precession and trajectory of Earth? Watching us? All of these and more?
Could it be it is now broken and part of its initial functions don't work anymore?
There are pieces of granite figuring what we call the King's chamber that have been obviously machined or processed by some even higher technology also not available in the time and space we think they were build. Could they have been done as a last effort of some aliens after landing or by an automated drone sent here to establish communication and more while the rest of the pyramid was done by a zombified or genetically modified local primates for which they altered climate so they can be easily fed by the cyclical flooding of the Nile. Anyways, some of those stones now are cracked.
Forget about everything you hear in this video and just look at the images. The explanation with sealing the King's chamber does not last a bit. If they wanted to seal the King inside the pyramid they could have just poured more lime concrete blocks as they done with the rest of it.
(As a high school student i worked many jobs. Sometimes during summer i was chiseling inscriptions in marble. But the guy who was paying me to do this job once gave me a piece of what he called "black marble" to write something on it. Now i know what it was. It was a sort of black granite. While in marble i could do easily a one inch 3D dug letter in every 10-20 minutes or so, in granite i could barely scratch the surface and all my steel tools (my chisels for the job were made out of file steel, that is a steel that can file through other steels) worn out before i finished the job. Later i found out that granite is actually tougher than many kinds of steel, or the toughest natural building material, tougher than many types of concrete). How could the workers of the bronze or stone age with no high alloy steels process the granite to those shapes and with such a precision they could have been assembled and figure early machines without the use of machine tools and without current or even late 19th of early 20th measurement techniques. No way.)
I think they used some sort of small scale advanced technology brought on a ship that could not have lasted (both the ship and the technology) and they did it with the purpose of them to be opened when civilization on Earth had reach a certain stage. Or earlier by those knowing how.
My idea? It's got something to do with time. Preserving something in time. Maybe technology, maybe information, maybe our planet. Maybe it's a shape based advanced device or terminal linked to another planet that may accomplish things here on Earth. If they were objects, pieces of technology, drawings and/or devices in there they most likely ended in the wrong hands.
