“Un horizonte de sucesos puede caracterizarse como el conjunto de
puntos de la clausura topológica del dominio de dependencia de una
hipersuperficie lumínica situada en el "infinito" que no pertenecen al
pasado o futuro cronológico de dicho dominio.”
- Wikipedia

“Sólo cuando conoces cada detalle de la condición del
terreno puedes maniobrar y guerrear.”
- Sun Tzu: “El arte de la guerra”
