O naturalista
Claro, a radiação de Hawking não devolve exatamente os átomos que caíram lá, mas sim energia, mantendo o equilíbrio do sistema em termos de conservação de energia total. Quando dizemos que buracos negros "devolvem" matéria, estamos sendo generosos: o que sai não é a mesma coisa que entrou. A radiação de Hawking é uma emissão de energia térmica gerada por flutuações quânticas perto do horizonte de eventos — a fronteira sem retorno dos buracos negros. #
