Definition: Let zero cuil be defined as the singularity of zero abstraction. To obtain zero cuil one must know everything to zero levels of abstraction.

Hypothesis: Zero Cuil is unattainable.

Proof: The answer is intuitive through the Heisenberg uncertainty principle. To know something at zero abstraction, one must know all of its components. Since everything in the universe is composed of particles this demands that at zero cuil the person knows everything about all of the particles in the thing the person is observing.

Assume the person holds a hamburger at zero cuil

=> the person knows everything about the hamburger

=> the person knows simultaneously the position and velocity of all the particles in the hamburger.

but by the Heisenberg Uncertainty principle this is impossible. => contradiction => a person cannot be aware of all reality

=> the person cannot hold a hamburger at 0 cuil

In laymans terms: 0 cuil requires one to be aware of all reality, by the heisenberg uncertainty principle this is impossible, therefore any observation of anything requires some level of abstraction greater than 0.
