Original sentence: Bohm maintained that the wavefunction alone is not a sufficient explanation for all our observations; in Bohm's view, particles are needed simply to account for why we observe one particular outcome of an experiment rather than a superposition of outcomes, as in the paradox of Schrödinger's cat.Response: Bohm accepted that the particles in his interpretation cannot be observed directly, but nevertheless he thought the concept of particles having definite positions even when unobserved contributes to the theory, so, in Bohm's view, the comparison to the luminiferous ether is invalid.Without particles, some additional processes such as collapse, decoherence, or splitting universes are necessary to connect quantum theory to experience
