But, that assumes that it is the same time horizon as what we experience. I've often thought of the scenario where we are living on something that is like a quark of an atom of a much larger existence. And that maybe we make up a small bit of a dude who is sitting around having similar thoughts. But, this enormous (to us) dude moves on an extremely slower timeline. So slow that they there is no possible way we could communicate, even if either of us realized. And in the same regard, there are whole worlds that exist inside the quarks that make up the atoms that make up us. Maybe it is even a recursive existence that goes on to infinity. Because, why not? Prove me wrong. :-)
