There will be a galactic alignment on December 21st that happens once every 26,000 years. The last time it happened the world was in an ice age.
That much is fact, but........no I don't think it will end. Some microbial bacteria and small subterranean organisms should survive, but the world itself will be fine. It wont end.....just humans and most other life!!
(Not serious)
I did take a vacation day from work that day just in case. I'm not going to be there if shit goes down...lol
