Who is the observer in Quantum Physics?

Answer 1

It seems your wondering about the "Problem of Consciousness".

The short answer is "humans have no idea where or who or how things observe". Everything in the world seems deterministic meaning the present universe timeslice was determined by the past universe timeslice after quantum physics acted upon it.

Even if we do find out which nuron fires at precisely the time when you sense the color blue, it does not help us determine where consciousness comes from.

Either there is a special way to configure atoms to give them the ability to feel, or somehow consciousness arises from the proper configuration of many atoms. It could be possible that each atom is conscious, it's just that not all atoms have an elaborate self replication system called your body.

It could be that the observer in quantum physics is somewhere beneath the implementation and expression of the atom itself. The atom is not yet understood and we may not be intelligent enough to understand yet. Just as it's difficult for a fly to understand the process of figuring the area under a curve.

Who is the observer in quantum physics? You have to break down the question and ask "how do we know when we have an observer?" Is a monkey an observer? A fish? A bacteria? Is a Chess algorithm an observer? Is fire an observer? Are people in comas observers? Then you have to more clearly define: "who". Who implies a person. Then you have to define Quantum physics.

The observer is manifested through a certain configuration of atomic particles. The observer may be a different form of matter. The observer may be an illusion.
