Hi neo-geo; I had a pretty difficult time understanding your post; is English your native language?
I have afew quick things I'd like to address about what you said.
plant x dosnt exsist as this is supposed 2 be the sun,s moon which ours dosnt have if it did the sun would grow red and not the yellow we see
Actually, planet X is not supposed to be the sun, but rather a Brown Dwarf
; the majority of the solar systems are binary systems; if our sun is the only star, than we would be the exception.
we would need a major impact event 2 change the earths axis
In case you are not aware, the earth's axis is always changing; a Pole Shift could result in a tipped earth, as well as a change in the earth's magnetic shield.
Here's an interesting site: http://www.divulgence.net/
I recall an article by National Geographic on pole shifts, providing evidence that the earth was tipped in the past; I wish I still had that article.
people also belive the sun on the 21/12/2012 will be at the centre of the universe not possible as no one knows the extent of the universe .
Wait, who said the sun will be at the center of the universe? You may be confused with the procession of the equinoxes.
The event which is supposed 2 take place is being so called the dark rift and i can see why the cosmic event that is 2 take place is when the sun rises on this date it rises in what looks 2 be the center of the milkyway the center of the milkyway is supposed 2 be dark this is where the sun is supposed 2 enter /pictures of milkyway looked at by the hubble telescope/ this is supposed 2 effect our day light as we know it. As this event only happens every 26000 years nobody knows what will realy happen when this event takes place .
This theory sounds pretty interesting; I'd like to read up on some more articles on this subject, if you could please link us.
the last time this event happend the world end its last ice age and we evolved from neandathol man 2 homosapian.
I have to go, but last comment here; according to the theory of evolution, I'm pretty sure the Neanderthals and Homosapien were two different chains, which were around about the same time (whereas the Neanderthals ended up going extinct or cross-breeding with Homosapien); I may be wrong though.
