The quantum wave function isn't real

The universe isn't a wave function

The dominant interpretation of the quantum wave function sees it as real – as part of the physical furniture of the universe. Some even go as far as to argue that the entire universe is a quantum wave function. But this interpretation runs into a number of problems, including a clash with Einstein’s theory of relativity. Karl Popper prize-winner, Eddy Keming Chen, suggests that we instead interpret the wave function as the basis for a law of nature that describes how particles, fields and ordinary objects move through space and time. That way, a number of puzzles around quantum mechanics are resolved.

 

Believe me when I say it's easy to love quantum mechanics—the fundamental rules that describe our physical world, starting at the microscopic level —but hard to interpret what it’s really about. Quantum mechanics is unquestionably useful as an algorithm for predicting the outcomes of experiments and has given birth to many technological innovations

If this framework does not make any physically testable predictions it amounts to nothing more than mental masturbation. Interpretations of QM alog such lines are a dime a dozen.

I agree with Martin Swinkels’ comment; that this article is not written clearly enough to even form an opinion about it

Perfect explanation of reality and the universe and its code and other parts. Great job.

I don't think this article is written clearly enough to even form an opinion about it. I have many questions about the pixel metaphor which could have been answered if the article had been written more clearly.

As Wolfgang Pauli used to say, this is "Not even wrong".
