An interesting question in the below linked article.  The reality is — if our manifest causal universe is either a computer simulation or an aspect of an overarching consciousness, then as we may only measure and interpret data via instrumentation that itself is a part of the same manifestation, then we may only ever gather empirical data as allowed for by the simulation/consciousness.  In short, unless we can measure from outside of the universe, we will never really be able to define what the universe is.  It may all be but “a dream within a dream”, as Edgar Allen Poe wrote.
