Supposedly The End comes at 6:11 or 7:11AM. Another theory is that all the Mayan style pyramids aroud the world have to be energized by the rising sun. The final one is either in Mexico or South America.
When they have all been energized they will comunicate with each other and begin the destruction.
One problem is ...what if it’s raining at one or more sites?
That’s what is happening at Maeshowe in Scotland today. The mysterious burial mound with deep chambers is a marker of the winter solstice. The setting sun lines up with an entryway to a chamber and at the time of the solstice th back wall is lit.
There are live webcams...it’s kind of a big deal. Problem is it’s pouring down rain so no show this year.
