You write about the singularity, the “infinitesimal point of infinite density” within a black hole. The concepts of infinitesimally small and infinitely large are extremely powerful in pure mathematics. But is their use acceptable in trying to model the physical universe? (15 June, p 32)
At the centre of a black hole, the wave-like particles are fighting against the gravitational forces that are trying to compress them to a point. And if there really are such singularities, then by definition they can’t be modelled and can’t carry detailed information. Surely I am not the only person to question the use of these extreme mathematical concepts in trying to understand our physical universe.
