To clarify, the Galactic equator or Dark rift has emense gravitational influence it is like a huge disc with the centre being the centre of the Milky way (our galaxy that we sit on the edge of) and will affect the Sun's solar activity, which may be strong enough to cause solar flares and radiation bursts to earth. These could be as strong as to wipe out all computer chips and power grids, or stronger frying everyone with Gamma radiation (there was an event from solar flare in 96 i think that wiped out North Americas power for days). There could ofcourse also be rapid pole shift which could cause a great flood or eartquakes and 300/400mph winds etc... But the truth is no one knows and for an event that happens every 25,000 years it didnt wipe us all out last time so why will it this time.
This date 21st Dec 2012 is when earth is exactly mid way through the dark rift/ galactic equator, we are already moving through it so between now and 2015 when we finally pass below it some thing or nothing could happen.
My plan is to keep tuned to the news, be prepared with a bag of food,blankets, sleeping bags, camping stove, torch, first aid kit, wind up radio, tea/cofee etc and to be ready to get to a high point i.e 200meters above sea level and above if there are reports of oceanic earthquakes or tidal waves. Cant hurt to be prepared just in case!.
In the mean time put it aside in your mind and live your life as you would as it could all be a load of ballonie and wont have the slightest effect!!
