I believe this on the right side is the pyramid configuration with the Sun during those seconds of the day it can open a crack in space time continuum and get connected with another one nearby in the galaxy maybe up to a few hundreds light years away and maybe within the line of sight with no obstacles.
The Sun has to be roughly perpendicular or better said in the middle on faces 7 and 8 (the height will vary during the year, hence the length of the grand corridor and the stones used for tuning) and the photons coming at an angle from the periphery of the Sun have to be parallel with faces 1 and 6
Because of the round shape of the Sun, variable height throughout the year, things are a bit more complicated, however in that moment the rays comming from the periphery of the Sun near a horizontal diameter "hug" or run parallel with faces 1 and 6 and the photons get pushed aside and then twisted and bent by the faces 2 and 5.
In detail. A number of phenomena will occur. A change of polarization from near horizontal after light passing through atmosphere to one parallel to the surface that will be in opposite direction on faces 2 and 5. A change of direction of the photons during total reflection on faces 2 and 5. A transfer of momentum from the photons to the surface. A red shift with change of frequency and energy.
I said that a photon is formed of a one single virtual particle that re-creates self at a right angle and at a distance creating space and while re-creating self in the future creating time.
If we change direction of that particle simultaneously in two perpendicular planes, longitudinal and transversal we can bend space and time and if we combine that from two different faces of the pyramid we can re-create the original void.
Everything that is interesting inside the pyramid is on a plane in the middle of it but most interesting, there is a cave like structure called the grand gallery that probably initiate or guide that split. The three locking rocks and the tree sliding rocks could be tuning or "dialing" devices.
I believe the pyramid was used in the same way they did in the movie Stargate Atlantis. However, there is no ring, it all happens inside the pyramid, i don't think you can "dial" the destination, and another one at the destination has to be opened in the same time which is quite impossible since there is no possibility of synchronization because that planet turns probable at a different speed.
The idea is very simple. When you crack open the space time continuum, inside the void created the space (and time) has no meaning and if you open another one in a different place in that very same instant, only for i don't know, a few seconds, they will overlap with a slight calculated difference, and you can switch an object from one to another one.
But they could have at the other end devices more sophisticated as i suspect they could have here on Earth nowadays.
I got some proof. The recently discovered void inside the pyramid could be an effect of the erosion of the faces leading to focalization above the grand corridor rendering the pyramid useless for that purpose.
Or maybe the crack still appeared daily after the pyramid was abandoned (which suggests a war or evacuation with no time or opportunity to destroy such a wealth of information) and continued to function and the faces got eroded by rainwater, with more erosion at the bottom due to a cascading effect of small debris and the focal point was moved upwards and the void was created with all that matter being sucked and transported somewhere which may lead to the conclusion it did not need an opening at the other end.
Or was it an accident? A solar storm? An earthquake during opening of the wormhole? Or maybe simply the geographic center of Earth landmass could have shifter by erosion of shores, worldwide.
Here is an artist rendition on how the The Great Pyramid of Cholula might have looked like. Thou significantly shorter than the one at Giza, it has a greater volume and side surfaces. It was made of adobe bricks, but the surface could have been highly finished. Could have been concave (octahedral) like the one at Giza. Cholula in nahuatl language means "Place of those who fled". It was started in 3rd century BC and abandoned in 8th century.
