Description

The event horizons, and Cauchy horizons, of mathematical General Relativity are mathematical idealisations that are not particularly well suited to questions that physicists and astronomers like to ask.
For very many purposes dynamical trapping horizons are much more suitable. I shall give a brief overview of the current situation.
