Can you elaborate this a bit, thank you.
Let's put it like this: there is zero indication, theory or anything else that points towards the world ending some time later this year. Or next year. Or within the next decade, or whatever. As such, if the world would end any time soon, it would be without us having a way to detect it beforehand. Such as what with the theory of the universe existing only because it's an unstable anomaly, and might phase back into non-existence any moment. Sure, that can happen. But, as far as we know, it's unlikely.
Polar shift? Old hat. I learned about that in geography class 15 years ago. Not gonna happen within the next few million years. Before the magnetic poles shift, the magnetic field of the world will slowly become weaker, which will take a looooooong time. And then it will, within a comparable short time, flip. That happened in the past, as has been proven by the way magnetic thingies are orientied in old lava flows (learned that 15 years ago, so mind me if it ain't 100% correct what I remember).
There is currently no hint towards the magnetic field flipping any time soon.
And the whole maya thing is garbage anyway. They didn't even know the concept of apcalypse of any form. So claiming that they predicted it is totally weird.
All this is has been just blown out of proportion for the sole reason of making money. Ripping of people who believe stuff to easily, by making them buy books and stuff about something as unlikely as the world ending this second, in five minutes, or later this year.
It's not far away from all the esoteric stuff. "sit on the crystal and it will heal your hemorrhoids. I sell you the crystal for 5000$. Oh yes, it's worth only 10$, but I sprinkled it with magical crystal water".
The whole "end of the world" thing is super popular, especially in religious countries like the USA. It attracts viewers, readers, everyone. As such it generates money. As such the media try to keep it in the news, and try to influence the people with half-baked knowledge, bent the way until it fits, for the sole reason of keeping peoples attention and making money.
