I've heard this discussed as fundamental properties. Time, Space, Energy, Consciousness. Things which cannot be broken down into other things.
There was a nice TED Talk about it... searching... found it!
He mistakes the "movie in our heads" as consciousness, when I would say it is that which watches the movie in our heads.
