Max Tegmark is now touring to sell his latest book Our Mathematical Universe with the following opening:
- This book is my quest to explore the ultimate nature of reality, from the microcosm to our universe and beyond.
- When I think about the Copenhagen interpretation I just can't get this Hamlet quote out of my mind: "There is something rotten in the state of Denmark".
- The wave function never collapses. Ever.
- The fundamental reason that quantum mechanics appears random even though the wave function evolves deterministically, is that the Schrödinger equation can evolve a wave function with a single you into one with clones of you in parallel universes.
- So how does it feel to get cloned? It feels random!
The insistence to view atomistic physics to be based on a linear multidimensional wave equation (in 3N space dimensions for an atom with N electrons) without direct physical meaning, is a fundamental mystery of modern physics. Why insist on linearity? Why insist on 3 independent space dimensions for each particle without any common space to share? Why start out with an equation without physical interpretation which forces a probabilistic interpretation, as if physics is a giant insurance company?
Ockham's principle says that you should not ad hoc assume anything which makes things more complicated than necessary. Nothing dictates that quantum mechanics must be based on a unphysical linear wave equation in multi dimensions. At least what I can see.
PS My question to Max what makes him believe in a linear multidimensional wave equation asking for the Copenhagen interpretation, which Max says is rotten, did not get any answer. Instead of answering my question, Max asked me a question. I have met this tactic in discussions with both climate scientists and physicists, which may be quite effective in science. But it would be ridiculus for politician when asked a question by a journalist to turn the situation around and instead subject the journalist to interrogation, instead of answering the question posed. But here I am the journalist and my question remains to be answered.
