Um ok, First off am I losing my mind or wasn't this on the Tiki bar and if so why was it moved?
Any hoo... who says God has anythign to do with it. I mean I think it's a planet that evolved and grew with no help from a 'higher' power. So if it emplodes... so be it.

Re: Mayans insist 2012 isn't the end...
The future of the planet is closely tied to that of the Sun. As a result of the steady accumulation of helium at the Sun's core, the star's total luminosity will slowly increase. The luminosity of the Sun will grow by 10% over the next 1.1 Gyr (1.1 billion years) and by 40% over the next 3.5 Gyr.[40] Climate models indicate that the rise in radiation reaching the Earth is likely to have dire consequences, including the possible loss of the planet's oceans.[41]
The Earth's increasing surface temperature will accelerate the inorganic CO2 cycle, reducing its concentration to lethal levels for plants (10 ppm for C4 photosynthesis) in 900 million years. The lack of vegetation will result in the loss of oxygen in the atmosphere, so animal life will become extinct within several million more years.[42] After another billion years all surface water will have disappeared[14] and the mean global temperature will reach 70 °C[42](158 °F). The Earth is expected to be effectively habitable for about another 500 million years,[43] although this may be extended up to 2.3 billion years if the nitrogen is removed from the atmosphere.[44] Even if the Sun were eternal and stable, the continued internal cooling of the Earth would result in a loss of much of its CO2 due to reduced volcanism,[45] and 35% of the water in the oceans would descend to the mantle due to reduced steam venting from mid-ocean ridges.[46]

Im confused
VT, you brought God into the debate but then use science to ... uh..well, Im lost now bud  Do you think God would not allow it or not? Im thinking if the Earth has 500 million years left the Mets will win ONE more WS..right?
Secondly, the Mayans never said the Earth would implode, they said it was the end of a phase or something, and now the leading Mayan dude says its all nonsense anyway, its western misunderstandings of their ****..
im with Bec, steal all the kegs and lets party like its 1999, hmmm, that was a pretty good party, anyone want details on who I ..

2009, it just keeps getting better and better. Just ask David Wright..
