Well we are now in the second half of the most prophesized year in history, the ever so dangerous 2012! Many people have many different ideas on how the demise of this civilization just may occur and I thought I'd lend a hand at pointing out a few of the most popular theories. Keep in mind belief in any one of these theories will quickly get you labeled a "Conspiracy theorist" so be careful just whom you share your personal "End of time" theories with to avoid such a label. I'm going to focus mostly on how it may happen, as opposed to who and talking about the Mayan calendar, biblical references, or various aboriginal prophecies.
Google Nirbiru or planet X and you'll get lots of interesting info. Some of you may remember back in the 1950's and 60's in magazines like Popular Science running stories about "Planet X". As it's told, Nirbiru is on a 3600 year orbit of our solar system and is due back our way in 2012, latest date I heard was August 17th or September 26th. The danger of its orbit is that is reportedly 4-5 times the size of earth and is dragging along in its path a huge debris field of space mater caught in its gravity. Of course it's gravity will effect our weather and tides, possibly causing a giant wave large enough to destroy most coastal cities around the planet, finally I get a break not living near the coast. There are various ancient legends to support the story and a near total media blackout by most official sources since 1983 to add fuel to the theory.
Michio Kaku, physicist and futurist, recently pointed out that we are nearing the height of and 11 year solar cycle. These cycles often generate large solar flares, some large enough to generate huge waves of solar charged plasma called a coronal mass ejection (CME). A CME pulse is what is also generated by the detonation of a nuclear bomb and disables all electronics. Should a large enough CME hit the earth it could, in theory, disable all electrical transformers worldwide. Imagine waking up to world one day with no electricity and not having the ability to replace those transformers for 3-5 years as there are a very limited number of manufacturing facilities worldwide that even produce them, none of which are in the USA.
Every 26,000 years it said there is a Galactic Alignment of all the planets in the solar system with our sun and Earth. What effect would all of the stacked gravity of each planet along with that of the suns have on our planet, no one really knows. Theories range from a polar shift, or earth crust displacement, to theories of a potential formation of a super massive black hole near our galaxies heart. Either scenario would spell doom for our planet unless you are lucky enough to catch a ride on one of the governments special water craft featured in the movie 2012, that might be tough since I'm sure that was only a movie.
Of course our very government hasn't done much to dispel rumors of the potential end. Online sites have turned up government documents (Internment and Resettlement Operations FM 3-39.40) that include plans for mass concentration type camps to be built within our borders, ever wonder why closed military bases still show so much activity and the barbed wire on the top of the fences faces in and not out? Google the NDAA, Executive Order 13603 (National Defense and Preparedness), Agenda 21, HARPP, GMO's, contrails, new world order, illuminati, and red flag events and your head will spin with all the potential mayhem we could be facing, or not?
For now, most of the internet is still a wonderful place to learn and explore and gain knowledge of things that just a few years ago would have been impossible because of distances, governments, and technologies limitations. I far as what I believe? If the world suffers a galactic end there isn't a thing I can do to stop it, I can't store enough food to last forever if the lights go out for 3-5 years, and I can't change much about our current government. I'll just have to hang in there day to day, stay away from the coast, and pray if the end does come I'm right with God, and of course remember what they say, "What doesn't kill you will only make you stronger"
