- 3.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.
