Continuing on these ideas: Can language be thought as collapsing the state?
Wave function collapse (also called collapse of the state vector or reduction of the wave packet) is the phenomenon in which a wave function—initially in a superposition of several different possible eigenstates—appears to reduce to a single one of those states after interaction with an observer.
So the question is: Can the cat can be alive and dead at the same time?
The Copenhagen interpretation of quantum mechanics implies that after a while, the cat is simultaneously alive and dead. Yet, when we look in the box, we see the cat either alive or dead, not both alive and dead.
The problem here is both 1) the definition of death and 2) the observer’s attempt to understand activity by means of the categories of vision. It is indeed interesting: why does the writer talk about “we” looking in the box? Why is the setting built so that “we see the cat either alive or dead” is stated as unquestionably true?
I can think of several questions that makes the setting all the more fuzzy:
- At what moment precisely is the cat considered dead? What organ needs to stop functioning? Can we “see” when it happens?
- What if the person looking at the cat has gotten the wrong impression? What if the cat is faking it?
These questions inevitably lead to the conclusion that the cat’s death is first and foremost a state of the observer’s consciousness. To clarify this, let’s have another thought experiment:
A newspaper reports that Schrödinger’s cat is dead. Fans of the cat start their mourning period. Couple of days later, however, it reads that it was all a hoax and the cat is actually all well.
In this case, the cat was dead for the fans until the actual state was reported. It was not dead, however, for the person who looks after the cat. The cat didn’t even exist for people who didn’t know about it.
To sum up: it all depends from what perspective the situation is approached and what presuppositions are made. These are guided by the objectives of the actor.
