Singularities are typically moments where infinities kick in and beyond which it is impossible to make predictions. It isn’t just in physics that these singularities can emerge. There is a famous example, published in 1960 by Heinz von Foerster, Patricia Mora and Lawrence Amiot, which predicts a serious singularity here on Earth. The rate of population growth, if it followed the pattern of behaviour observed up to 1960, indicated that the population of the planet would become infinite on 13 November 2026. A Friday, it so happens, if you’re at all superstitious.
