I've read and heard all kinds of comments on the Galactic Alignment and center. I spent some time trying to figure out how something trivial like this could begin to be viewed even from farcical points of view as potentially dangerous.
Forget about who or why 2012 was picked for a little bit, I have plenty of nonsense theory to provide for this as well. What I would like to know is if anyone has information to debunk the idea of us entering into or too close to a galactic bow shock wave. Our Galaxy is moving towards the Virgo cluster of galaxies. Virgo contains around 3000 galaxies, our cluster is smaller this is why we are heading this direction. The solar system does cross the galactic 'Plain' every 26,000 years which last occurred in 2003 without incident, but the edge of the Galaxy that is positioned at the front of our movement happens only every 226 Million years. Think more like passing the Galactic Prime Meridian rather than the Equator and the prime meridian is the front of our Galactic vehicle. As our own solar system travels around the Galaxy it too has what is described as a Bow Shock wave ahead of it.

The collision of particles ahead of the magnetosphere produces a great deal of cosmic radiation. We do not feel terrible effects of cosmic rays due to the Suns large Magnetosphere and our Own Earths Magnetosphere.
Those who don't believe global warming is Man's fault often sight the answer lies in the Solar Cycle. I would be someone who doesn't believe the science is in on either side of the warming argument, and I assure you I am listening both sides. There are studies that attempt to connect the suns cycles of higher solar wind activity to weather phenomenon we have seen. Some say it increases cloud cover, I've also heard that as the winds push on the magnetosphere it causes jet stream patterns to Arc to and from the poles creating warming near the caps and pulling colder air toward the equator. This aside, the point is cosmic radiation might have an effect on weather patterns. Also the magnetosphere flexes with the movement of the core and the radiation forces externally acting on it.

The Galileo mission to Jupiter's moon IO recorded volcanic eruptions higher than we anticipated possible. The plate tectonics were clearly influenced by Jupiter’s Gravity, but there was an extra boost to the propellant attributed to electrical arcing from Jupiter’s Magnetic field which is many times larger than Earth's. Electrical theory says that when you pass a current through a wire you get a corresponding magnetic field on its exterior. In the reverse direction if you move a magnetic field over a wire/conductor you get electrical current. The point here is magnetisms effects on magma.
What would a bow shock wave caused by something as massive as a Galaxy be like?
It would seem that a mass moving into an empty space should cause no such wave, however a theory of quantum physics states that on average space is not empty. There are particles that the Galaxy's mass, gravitational waves, emitted particles would most likely be colliding with. Why would there be no such shock wave.
So the sum of all this is, what if in 2012, despite how we arrived at this date, we arrive at a point in our orbit where we are in a region of space with intense cosmic radiation, with the sun between us and the Galaxy, leaving some of our Magnetic protection on the wrong end of the solar system for us, outside of the Galaxy's magnetic influences as well as we climb above the Galactic latitudinal plane. Additionally our current Solar Maximum is scheduled to end in the year 2012. Would a super intense wave of cosmic radiation compress our magnetosphere towards our core, agitating our magma energy enough, influencing our weather patterns subtly enough for disasters, bathing organisms in enough radiation to cause death and unviable mutation to actually lend some credence to this 2012 myth?

Some also refer to this side of the Galaxy as the North Side for you Nostradamas people.
Again, forget how the date was arrived at, from a science stand point, please present the evidence against.
