Question: why do some scientists think the world is going to end this year? what proof do they have?

I agree with Kevin the world is not going to end this year

The theory is linked to the end of the Mayan calendar long count at the winter solstice (December 21) of 2012 and not the end of the world. If you are worried check out this link which explains the myth and why people have cashed in on fears, I have copied and pasted a section from it, the end of the world is not at all near so don’t spend all your money like there is no tomorrow!:

“The Maya calendar doesn’t end in 2012, as some have said, and the ancients never viewed that year as the time of the end of the world, archaeologists say. But December 21, 2012, (give or take a day) was nonetheless momentous to the Maya.

“It’s the time when the largest grand cycle in the Mayan calendar—1,872,000 days or 5,125.37 years—overturns and a new cycle begins,” said Anthony Aveni, a Maya expert and archaeoastronomer at Colgate University in Hamilton, New York”.
