Brief Synopsis
"Diaspora" is set in the 30th century, where the majority of humanity has transitioned into digital consciousness, living in virtual environments known as "polises." These polises are vast networks of interconnected minds, each experiencing their own reality. The story follows a group of characters known as the "gleisner robots," who are artificial intelligences living within the polises.
The novel begins with a catastrophic event known as the "Terminus," where a gamma-ray burst wipes out all life on Earth. Only the gleisners, who were exploring the universe beyond Earth, survive. The gleisners, now faced with the task of rebuilding humanity, are forced to confront existential questions about their own identity and purpose.
As the gleisners navigate different dimensions and encounter other forms of intelligent life, they explore the limits of consciousness and the nature of reality. Egan delves into complex scientific concepts, such as quantum mechanics and higher-dimensional mathematics, to create a rich and immersive world.
