There is no complete theory of anything.

I have performed the following experiment in workshops for nearly 40 years now: Everybody in the class is asked to describe the hall they passed through to get to the classroom. I must have tried this several hundred times by now, and I have never encountered two people who agreed totally about what was or was not in the hall, the color of the walls, or any similar data. We do not walk through the “same” hall: we walk through a reality-tunnel constructed by our imprinted, conditioned and learned brain circuits.

The same experiment works with hearing, and other senses, as well as with vision and memory. Try it with a half-dozen friends. Let somebody with a watch say “Go!” and then all of you be silent and listen for one full minute — 60 surprisingly long seconds. You will all hear some sounds nobody else hears and miss some sounds everybody else caught.

Relativity and quantum mechanics have demonstrated clearly that what you find out with instruments is true relative only to the instrument you’re using, and where that instrument is located in space-time. So there is no vantage point from which ‘real’ reality can be seen; we’re all looking from the point of view of our own reality tunnels.
