But what does it mean, exactly? Maybe the fact that it can reach any place on Earth equally. Maybe it has something to do that ionosphere raises more above dry land than oceans and in average is highest at that point.
(In the link below is being talked about the particular Mer-cator projection, which probably was designed from the beggining as a confusing point. Mercator is the name of a geograph and does not have anything to do with the historical name of the Pyramid in both Sanskrit and old Egyptian).

Pyramid is called Mer in ancient Egyptian language.

I didn't know until yesterday about mythical Mount Meru mentioned in Hindu cosmology. It said to be in the center of the Earth. All these coincidences to me suggest Mount Meru from Hindu cosmology and the Great Pyramid are the same thing.

There are several depictions of Mount Meru shown symbolically as a pyramid with a structure inside resembling the one of the great pyramid. Both to me suggest resonating cavities.
The upper side of both above and below pictures also suggest resonance but with the ionosphere, and connection to the aquifer behind and further with whole Earth. Let's not forget the fact that initially the top of the pyramid was cover with gold. Also. Desert place implyes dry air and good insulation between top and bottom achieved through limestone.
Now let's take a look at this video and forget everything it's said in there. Just remember the sliding blocks of granite (three, to tune the resonating cavity, one sliding down the gallery that triggers the vibrations).
It is said in this blog post the gallery saw in the video, with saw-tooth like roof is some sort of resonator.

Now let's try to put all these together. There could have been something like a piece of wood covering the whole cross-section of the gallery like a door attached to the granite block sliding down the gallery that could touch the roof and move and produce a shock wave at every step of that reverted ladder and make the cavity (so calle King's chamber) vibrate. The vibrating pieces of granite on top would produce voltage through reverse piezo-electric effect that would get amplified from slob to slob and pumped in the gold cap of the pyramid through a conductor or maybe even a two coupled coils pretty much like in a piezo lighter (snake symbolism). The effect must have been cumulative and something in the structure on the high voltage part might have acted as a diode so with each bump of that piece of wood in the upside down ladder more voltage would have been pumped in the golden cap until tens of millions volts would be reached. (Thinking here of some of the symbolism in Taylor's Swift video, the high kick, the pendant, the shape of the pyramid figured with legs, many hands, etc.)

Northern shaft which points at Polaris would have served as feed-back as the whole thing would oscillate, for measuring amplitude and frequency. Precise timing with day time, Moon position-phase, etc, would give windows for different geographic targets of using the thing within a daily and monthly cycle. Or maybe it allowed communications through quantum entanglement with the command center which could have been anywhere on Earth.
Or maybe some wooden legs where attached to the granite slobs and move like these? (second 43)
The last piece of granite could have looked like this toy above, equipped with wooden legs and vibrate the electrified pyramid at very low frequencies to accomplish the deed like the waves in AC/DC video (in the final, "and i'm going down"). With some not so difficult to make calculation regarding position of Sun and Moon and the target on the map the timing and voltage would have been chosen. Earthquakes, gigantic lightnings, other disasters, name it. Also the granite slabs on top of the chamber had irregular shapes. Could it be they charged the upper walls of the pyramids slightly differently in different areas, accomplishing something like a phased array antenna and direct a beam of low freq electrical waves towards a precise direction.
A global weapon built with stone age technology based on very ancient or alien knowledge.
There are many songs in modern culture that may make allusions to all these of some i haven't been thinking to this moment. Could it be thwrowing of that silk shroud symbolise the raising of the ionosphere etc.
The Great Pyramid has more shafts and it could probably modulate the electrical charge creating waves of high amplitude and extremely low frequency that would shake the ionosphere creating patterns and interference in precise areas of the Earth surface.
Just found another image with a cross section of the King's chamber. The roofs made of granite on top are not plates as i thought but beams that have been processed on three sides only and let with one rough. However they are too grossly rough not to mean something. I mean instead of being processed to less than 1 mm tolerance for the granite pieces to sit on top of each other without creating tension that could lead to acreage, the could have been processed wit one inch tolerance. However i see on top feet or fraction of meter irregularities. Could those beams be actually maps mirroring mountain chains or maybe some galactic maps?
However i found that the blocks or lime stone or "primitive concrete" bricks are set on layers. What does that mean. Could that have been important for a simple burial monument. I don't think so, not even for making it easier to build. Stone had to be cut at the same size at least on one dimension.However something else emerge here especially if we look at the above blue and yellow picture.
Friction may arise at the separation plans during daily heating and cooling cycle. Due to pretty big pressure at the base of the pyramid friction would be enormous. Some instant heating and vaporization follow by condensation may occur with weird changes in entropy, gravity and time, and the number, shapes and orientation of the plans could create some sort of unknown to us waves that would probably allow opening of a wormhole.
