I have never been into conspiracy theories, especially not the whole Mayan Apocalypse/December 21, 2012 stuff. While I lived in Guatemala, I met a lot of Mayan people who still practiced their religions, and NONE of them cared about December 21, 2012. At all. They thought the whole thing was laughable – not to say they didn’t take advantage of the hype to make some money off of tourists once in awhile.
Anyway, a friend of mine was telling me about weird noises that people are hearing around the world. I blew it off, until I saw a lot of news reports and videos of this stuff.
In most of the videos, you can hear a sound similar to a huge metal gate opening very slowly. I’m sure there are a lot of hoaxes out there, but a decent number of these seem legit, especially when you see the way animals react to the sounds.
This is completely off topic, I know, but I wanted to put this out there to see if anyone has rational, science-based explanations for these sounds.
