that we all live in the same universe, but we all have our own "perception filters". What is the difference between this "model" and that which you described you ask? Well, to me, the concept of living in your own unique universe is somewhat dangerous since it understates the effect that we have on each others lives. Sure we all have our own way of perceiving the universe, but the actions of others can plunge us into a heaven/hell beyond our control.

By the way I am a Physicist (a dead end job I suppose). There is actually much debate within the Physics establishment as to whether Physics is "fundamental" i.e. it describes the universe as it is, or whether it is simply a tool of our perception. I tend to believe the latter. However, since our collective perceptions shape the universe as we see it, I believe that Physics is not a "dead end road", but an important journey.
