Penrose: Quantum Mechanics is Inconsistent = Wrong

Nobel Laureate in Physics Roger Penrose tells a group of physicists about Quantum Mechanics QM as the pillar of modern physics based on the Schrödinger Equation SE:

  • QM does not really make sense.
  • Schrödinger, Einstein and Dirac said QM is incomplete.
  • I say QM is inconsistent.
  • Matter does not satisfy SE.
  • We need some new ideas.
  • We need creativity to go beyond current theories of physics.
  • We need to combine QM with gravitation.
What Penrose is saying is that QM as a theory supposed to describe real physics does not meet that requirement because real physics must be consistent and so cannot be described by an inconsistent theory. The group does not receive these revelations with shock, but rather with acceptance as if there is no hope. 

Consider these statements following common logic:
  • A consistent mathematical theory is a theory without contradictions. 
  • An inconsistent theory harbours contradictions. 
  • Contradictory physics cannot be real physics. 
Penrose follows this logic and concludes that QM does not describe real physics and so asks for some new version of QM based on something different than SE in its standard form as StdQM with its probabilistic interpretation as root cause of inconsistency. 

Real Quantum Mechanics RealQM is a new deterministic theory based on a new form of Schrödinger's equation in terms of classical continuum mechanics in 3 space dimension as a consistent model. 

RealQM may be the new idea Penrose is asking for. I will ask him to take a look and see, and report if I get answer. Well, I get the message that Penrose at 93 no longer reads his mailbox, so the question goes to some younger physicist. StdQM itself is now 99 years old. 

Does it matter what Penrose says? Does it matter if what he says is true? He is not alone, but of course his view is not the consensus of a majority, if there is anything like that. Is it worth listening to Penrose? The debate on the meaning StdQM has been going on for 100 years, without any resolution. Maybe it is time for some new idea?
