Abstract We discuss the formation of black holes during the very early stages of a universe in which the gravitational ‘constant’ evolves with time. We argue that black holes will retain ‘memory’ of the value of the gravitational ‘constant’,G, at the time of their formation. Their horizon size and their thermal characteristics are determined by the value ofG when they form, not by the value we measure in the external universe today. The observational effects of primordial black hole explosions are therefore radically altered.
