Well the science stuff is definitely untrue - there's no credible evidence for any of it.
I don't understand much of it but it's definitely not true. You can even see for yourself that there are no solar flares, no weird alignments. There was a normal alignment on the 18th (or was it the 19th) but that happens every year, and we didn't even notice it..
The Maya - well, they had a very, very different to view to most of us.
The Maya believed in cyclical time - which we don't - and they also believed humans were created four times over, starting from, em, wooden things without souls.
They counted time very differently, and named a certain length of time a B'a'ktun. We are nearing the end of B'a'ktun 13 .. They believed that the last B'a'ktun 13 was the start of the fourth world .. Importantly this is all symbolic and not to be taken literally. So even to the Maya there'd be no reason to panic. Incidentally, the Maya there are left in the world aren't worried..
And not only that but we know it's most likely shite - because we all know about evolution, the big bang etc. Things which prove there haven't been four worlds.
Besides, the Maya believed the world started in like 3000BC or something. How do you then explain fossils that have been proven to be older, the dinosaurs, etc?
It is a set of beliefs and understandings that ancient people came up with as a way of explaining life's unanswerable questions. They used what they saw and knew. We know more, we can see more, we understand more so naturally over time their ideas and predictions lose credibility.
Not only that but the Maya referenced periods of time that would cover 20 b'a'ktuns. If they believed the world ended at the 13th one, why then have a period of time covering 20 of them?
Been less anxious today although still worrying about tonight/tommorow. Got my hair very very short (now sits at my ears rather than my shoulders!)
