### The Sub Quantum Problem Goes Beyond the Quandary of Measurement

Wave Mechanics compute probabilities of occurrence. Given the wave W, an infinitesimal variation of W is dW = i (Hamiltonian (W)) dt. The simplest differential equation imaginable (Schrodinger Equation, SE). Then the particle jumps out where W is strong, according to SE. So we get Quantum jumps: W becomes a point particle. That was the experimental situation for 95 years (since De Broglie got SE). However, we now know that there is another process than Quantum Mechanics at work: Michel Devoret and Al. were able to predict Quantum Jumps (published June 2019). Quantum Mechanics is thus incomplete: it can’t predict itself (but Devoret can!) Call this existing situation Sub Quantum Physical Reality (SQPR). The question with SQPR is what could it be? Nonlinear, for sure, because so are the “jumps”. This is no Platonic debate: SQPR could well bring predictions (or postdictions?) such as Dark Matter. At least, so I claim. Notice also that local time (central to Poincaré’s Relativity theory) is a Quantum phenomenon (it counts photons oscillating between mirrors). Thus SQPR is not bound by it (thus to claim SQPR violates Relativity is no objection)..
