Ortogonal de Greg Egan: Forma do cosmos


No The Clockwork Rocket de Greg Egan (o primeiro livro da série "Orthogonal"), Yalda argumenta que

If the cosmos were like the surface of the sphere, everything would be "absurdly predictable" and observing the light field in one speck of the cosmos would give you all the information about the entire field in all of four-space.

Ainda assim, mais tarde em As setas do tempo (o terceiro livro),

Scientists agree that the cosmos actually has the topology of a 4-sphere (after ruling out the torus). The issue Yalda pondered in the first book is not brought up again.

Isso significa

that predictability does not matter so much after all (considering that it is even possible to send messages backwards in time)? I am slightly surprised that the issue that was discussed in great length in the first book does not surface again here.

(Este é essencialmente um follow-up para Topologia cósmica em Greg Universo Ortogonal de Egan , mas eu não tenho permissão para comentar lá.)
