Chris Langan might be really smart but his theory is kinda silly. He makes a big deal out of the simple fact that an object cannot be defined externally in terms that were meant to describe its inner workings. It's just like how you can't speak meaningfully about a person, whether you mean to describe his/her personality or just external features, by talking about the number of mitochondria in his liver cells. It's impossible to "see the universe" from an external perspective, within the context of anything other than its own contents, so why bother trying to conceptualize or compartmentalize it? It's just an ego yawn for him, I'm sure.
