    The allusion is to Penrose’s hypothesis that quantum superpositions remain as long as the difference in the spacetime manifold, entailed by the different mass configurations, is kept below some threshold value. Above that limit, he proposed, some nonlinear dynamics, emanating from an as yet unknown theory of quantum gravity, will cause a collapse. See, e.g., R.

    The speaker refers here to a useful term coined by J.S. Bell in his Speakable and Unspeakable in Quantum Mechanics (Cambridge University Press, 1987), where he distinguished between ‘beables’ and ‘speakables’.Google Scholar
