Are Periodic Mass Extinctions on Earth Caused By Variations In the Alignment or Movement of Our Solar System?
As I noted Wednesday, the “Mayan 2012 prophecy” is bunk.
But – digging a little deeper – it appears that some scientists have proposed that regular variations in the alignment or movement of our solar system over the course of many millions of years – perhaps even alignment with the galactic plane – may periodically cause mass extinctions on Earth. See this, this, this, this and this.
- Is still being hotly debated between scientists
- Even if true, would be on a completely different timescale than the 2012 myth.
In other words, this is something which would be interesting – and perhaps valuable – to study in the long-term … but there is no urgency to figure it out this year.
