Like the famous '90's R.E.M. song, it's the end of the world as we know it, or is it?
Doomsday believers say 12-21-12 is the day the Mayan calendar ends, and that's why the world ends that day.
"The whole idea of the Mayan calendar, there's a lot of conspiracy theories that are floating around about it. Everything from Planet Nibiru crashing into us; some people have even said zombie apocalypse," said Brownwood resident Dano Dunham.
On Thursday, the streets were just as busy in Brownwood as any other day, and people don't seem too convinced.
"The world is not going to end, you can probably relax, but if you want to go out and have a good time and pretend like it is ending and carpe diem and all of that, that's fine, just don't do anything crazy," said Dunham.
December 21 is however, the date of the winter solstice, the shortest day of the year, and marking the official start of winter.
"That's the only thing I'm worried about. It's the winter solstice, maybe the poles are going to shift," said Dunham.
Well, we only have to wait until Friday to find out.
