The Universe is definitely trying to tell us something.
What it all means remains to be seen. Of course, I have a few of my own ideas.
Could X stand for Xi? The ancient Xi people were misnamed the Olmecs of South America. Maybe they're angry about being cut out of history.
Some theories suggest the Xi may have had a connection to the lost civilization of Atlantis. Maybe Atlantis is returning with a vengeance.
And then there's my favorite X wearer of all time...Michael Jackson...just because :-)
UPDATE: Whoa! Right after I hit the publish button on this post I saw one of the X-Men creators has died. I'm a little weirded out right now, to say the least.
