Has anyone tested if things finally get weirder the closer you get to the center?

That was one of the main reasons why I found this game so interesting. I remember seeing a slight reference towards that mechanic during waking titan. And now that there are "weird" planets and there's apparently something that happens at the center, (I'm not there yet, please don't spoil) I was wondering if anyone tested to see if this mechanic has been implemented yet. I'm not gonna cry if it isn't. I'm just very curious.
