Did she say the codex says our sun will move to the center of the galaxy? And then everything floods, yada-yada...
Welp, we're currently about 26000 light years away from the center of the galaxy, and if we were heading for it (which we're not) we'd have something else to worry about over there instead of a flood, like Sgr A* which is speculated of being a supermassive blackhole. Also good loving luck covering 26000 light years in 3 years. Yeah, also Mayans didn't believe in the apocalypse, it wasn't a very strong component in their religious beliefs.
The way people are trying to tie their beliefs to the Mayan Calendar is pretty handicapped. The whole mindset nowadays is that everyone thinks they're so important that because they're eventually going to die means that everything else also needs to end with them. Wake up.
