Daaamn. The firmament is supposed to collapse during this time according to ancient Sumerian Anunnaki records.

This is the most accurate dome video I have ever seen and worth 23 minutes frens. It is amazingly correct. I'll share the science below.
I should do a step by step breakdown of this video someday, as there are so many details they have right. I had no idea these texts even existed till now. The 7 supports are dedicated energy streams to sustain the harmonics to keep the dome in place creating a 7 layer frequency fence that will destroy anything trying to get in or out unless you know the precise 'doorway'. This stops the Guardian Alliance from being ships in to help free humanity. The science is breathtakingly perfect.
As I've said before many x, it is standing wave harmonics that holds the optically-clear dome in place (cymatic technology). The 'compressed air', as mentioned above, is actually ultra-dry deuterium microcrystals that are in every drop of our ocean and meteoric (rain) water.
The image below is NOT accurate, but gives you an idea of what's happening. Both of these domes are 'local', meaning over just our one area within the 'outer space' of the other 177 worlds. Above these is another 'great dome' that covers all worlds of the 3rd dimension. What is above the domes are NOT waters as in from your tap, but air, which is actually thin water. Take a second and look it up.
The outside dome you're seeing would have been the one dome for regulating perfect climate for human earth (Tara) plus a number of other worlds between the inner and outer domes. But in defiance to Enki, Enlil created a dome within a dome to cordon-off Tara from the rest of the worlds as a permanent prison. Enlil is known as the god of the air or skies.
In the documentation of the construction of the dome it adds 2 characters after the name Enlil; prompting the author of the video to claim that's another different Enlil, not the deity. But it isn't. It is referencing Enlil as the builder of the dome in 10,400 BC. "Enlil" is an office, just like the president of the United States. You can have anyone run the office, as long as they do it the way the office is supposed to be run. If it is Enlil, it is 'president of the air', just like Enki is 'president of earth'.
As you heard, the dome is supposed to collapse within 40 years from today's date. But I am certain it will come down very soon now, as this is the stellar activation cycle and everyone else in the 3rd dimension has already left this time matrix, as this is the shuttering of the 15 level simulation. You either leave within the next 80 years, or you'll be trapped and will go with the entire matrix as it returns to source (except for Tara which is being physically relocated to a different host matrix). We don't want to be cutting the ascension any closer than about 75-80 years to the date the sun Starfire Returns to source, there's too much at stake and unforeseen glitches can happen to delay such things.
Yes, the world is 'head shaped' as the keeper says, but the land inside the dome is flat. The drawing on the right was from a high level IIIuminati member who leaked how the simulation operates. I strictly believe the ocean waves that are being artificially created to generate static electricity (orgone energy) that is powering the standing harmonics that keep the dome in place through secondary emissions and network covalent bonding, which makes all those quadrillions of microcrystals 'glass' like to make it optically clear.
