One thing is clear, the alignment of earth and sun in 2012 is purely visual and has no global or galactic significance.

NOW about our solar system(which moves in a sinosidal wave while revolving around galactic center). will it cross the galactic plane around DEC 2012 ??

This is the confusing bit and is the bit that can have actual physical significance if true.

I have found all credible but opposing views, Researchers at the Cardiff Centre of Astrobiology have built a computer model of the Solar System’s journey around the Milky Way so maybe they are more accurate in which case we havent passed the galactic plane and will pass in the near future, dont know what to believe

IT HAS ALREADY CROSSED 3 Million years ago

So, the question is, are we going to cross that galactic plane in 2012? Not even close. According to the journal nature, as well as many others, there is evidence of crossing this plane 3 million years ago. This would mean that we are moving away from the galactic plane and won’t be due to cross it for another 30 million years. In addition the margin of error in these calculations in at least 2.1 parsecs or about 6.5 light years making images like these completely meaningless. To conclude: If you hear someone tell you that the earth is on a 26,000 year cycle to align with the galaxy ask them how the wobble of the earth will change its position in relation to the galaxy. Similarly, if you hear someone say that the earth is on a 250 million year cycle to align with the galaxy ask them if they know that this happened 3 million years ago and wont happen again for another 30 million.

NO ONE CAN CALCULATE ACCURATELY IF IT HAS CROSSED OR NOT

You might be interesting to know that the Solar System bobs up and down above and below the galactic equator. It takes 64 million years to complete a full cycle going above and below the galactic equator. If you’re heard that the Solar System is supposed to cross the galactic equator in 2012, don’t worry, that’s a myth. It takes 64 million years to complete that cycle, so there’s no way to know exactly when it will actually cross the galactic equator.

IT IS GOING TO CROSS IN THE NEAR FUTURE

Researchers at the Cardiff Centre of Astrobiology have built a computer model of the Solar System’s journey around the Milky Way. Instead of making a perfectly flat orbit around the galaxy’s centre, it actually bounces up and down. At times it can rise right up out of the galactic plane – getting 100 light years above – and then dip down below it. They calculated that we pass through the plane every 35 to 40 million years.

And here’s the bad news. According to their calculations, the Solar System will be passing through the galactic plane in the near future
