John Bell in Memoriam: QM is a Dirty Theory

The book The Ghost in the Atom by Davies and Brown presents conversations with prominent physicists about The Mysteries of Quantum Physics. John Bell expresses the following views closely connecting to RealQM and Many-Minds Relativity MMR:

  • Behind the apparent Lorentz invariance of the phenomena, there is a deeper level which is not Lorentz invariant.
  • The idea that there is an aether (or many in MMR) is a perfectly coherent point of view. I think that the idea of the aether should be taught to students as a pedagogical device, because I find that there are lots of problems which are solved more easily by imagining the existence of an aether.
  • One wants to be able to take a realistic view of the world, to talk about the world as if it is really there, even when it is not being observed. I do find it helpful, the idea that there is a real world there, and that our business is to try to find out about it, and that the technique for doing that is indeed to make models and to see how far we can go with them in accounting for the real world.
  • I do believe there will be theories that are better than the ones we have, in that they describe more of the universe and connect more of it up.
  • I think it is very probable that the solution to our problems will come through the back door; some person who is not addressing himself to these difficulties with which I am concerned will probably see the light. 
  • An analogy that I like is that of the fly buzzing against a window when the door is open. It can be extremely useful to stand back from your problems and just wander about for a time, and it is quite possible that those of us who are somewhat fixated on these questions will not be those who see the way through.
  • When I look at quantum mechanics I see that it's a dirty theory. The formulations of quantum mechanics that you find in the books involve dividing the world into an observer and an observed, and you are not told where that division comes. So you have a theory which is fundamentally ambiguous, but where the ambiguity involves decimal places remote from human abilities to test.
The sad reality is that John Bell is no longer real to serve as a voice of reason. But his thoughts are alive!
