It's the end of the world as we know it.

[Warmaster Horus]

Well, in my humble opinion... I don't think so.
For one thing, what do they mean by "end of the world"? Earth is due to explode (or implode... be destroyed, in any case) in millenia. And not in 4 years. So what could be the end of the world?
Also, the alignement happens every 25,800 years? Well, it happened 25,796 years ago, and we're still here, right?
The way the world is right now, yes, the next few years/decades are going to be difficult (inflation, political instability, environmental disasters, etc.), but I don't think the end of the world is upon us. Yet.

Note that I don't know much about the subject in question. It just seems improbable to me.

EDIT: by the way, is this the right forum for such a question?
