I don't want to worry you, but . . .
You hear the weather forecast, later you tap the barometer, then look out at the hills and see the rain coming. So you take an umbrella.
This is the weather forecast.
It rather depends on what was happening at the centre of the galaxy 23,000 years ago. But if, as expected, it was then drastic, such as the super-dense galactic core routinely sucking the few nearest stars to its bosom, causing a mass flux ejection from it, then there is an oncoming cosmic shock-wave. Any who hope to survive the consequent coronal mass ejections from the sun starting its pass through the galactic plane in December 2012 should take the following to heart for thereafter.
When the initial wave does come, and from the geological record, such occurrences apparently happen regularly each fourteen thousand years or so, one now being somewhat overdue, it will arrive without warning, as it moves at more or less at the speed of light. It is this routine outward pressure that prevents a galaxy from collapsing in on itself. The intervals between the waves depend on a galaxy's size and composition.
Here on earth the intense shock-wave in passing will cause vast earthquakes, hurricanes and immense tidal-waves and, impacting the sun, will excite it to expel vastly more energy than usual. This can punch through whole areas of the planet's magnetic and atmospheric protection and fry any terrain beneath, the ensuing firestorms rendering much of the planet temporarily uninhabitable and most of the surface livestock so much fertiliser. That means us.
However, let's not overdramatise the situation. The old planet will survive as it always does, with its remaining life regenerating once more. Your experience of the event will simply be of the house falling on you, as in any common-or-garden earthquake, or as a ten-mile-high wall of water washes through the coasts and smashes your city to fragments. You will either just stop, or you will survive. If you stop, you have no further problems. It's afterwards that things will be very different.
Any such disturbance will then infiltrate our solar system with dust and cometary debris from the Kuiper Belt and the Oort and Hills Clouds far outside the solar system, thus promoting a new Ice Age. There is a lot of material out there - ten or twenty times the mass of the earth - just waiting.
'The media' had not come into existence the last time to misreport such events and slant their significance to favour its darling 'chosen', but the geological record is there and presents the evidence with honest impartiality.
So, if you read or view the confirmation of its facts in the URLs herewith, the Spitzbergen seed-bank and the underground cities that are already constructed at various locations of the earth then achieve a rather different significance.
Then why should the vermin-that-be be bothering with wars and pestilence to wipe us out, when the galaxy core will oblige by providing the same result without them lifting a delicately-manicured and -perfumed finger - thus even preserving for them their carefully-sanctified philanthropic reputations?
Are the flu and vaccination programs, wars and financial collapses and such simply to distract our attention while they finish their preparations to disappear into 'their' underground cities? - all paid for by us, of course, the wondering sheep. Lack of a few wars at any time would give us the leisure to see what they are doing, and the free muscle to interfere.
Doubtless these villains will have the hourly-changing codes on the underground food-stores, to ensure thereby the necessity of their own survival, and on the seedbanks for such time as the emergency is over, which will give them leverage in the re-institution and -infliction of their fiction of finance, bribery, politics, media, central banks and all. But don't be surprised, you who will be guarding them at their subterrene caviar and quails-in-aspic, if they have you eating each other, the better to control you and keep you on your toes and the edge on your murderous 'competitive spirit'.
What was that, Reader? Why don't they share this information with whom? They tell . . . us!!? Are you out of your mind? Weren't you listening when they told us they wanted us off the planet? What's the betting that 'they' have long since 'opened negotiations' with any aliens to which they have access, to ship them out of this galaxy for the duration of the problem and ship them back on another time-warp when it is done and enough of us have survived to produce some kind of system that they can then exploit? - Probably sold them a cast-iron guarantee with God for the forgiveness of their sins and salvation for evermore. You know their style by now, surely!
But the Rothschilds have already prepared for themselves and their accomplices. Then so should we prepare, individually and collectively.
If you have a cellar, make it habitable, secure and comfortable. If you are lucky, you may be occupying it for some time.
