Welcome to 2012 everyone! Most people have heard that because the Mayan calendar "ends" this year, the world will end also. It's been a huge story that has spawned movies and TV shows, but it's a big misunderstanding.
NASA has a new FAQ site that debunks the whole 2012 apocalypse myth with real science. It talks about the realities of the Mayan calendar and how there is absolutely no scientific evidence or reasons that the world will end this year.
It is a great read and something that teachers can use to show their students how little things get misinterpreted and blown out of proportion and show how science is important.
I also love the cartoon below.
