"[W]e cannot "see" a person who lived a few centuries before, because the light rays... have... left the solar system. Conversely, we cannot "see" the Andromeda galaxy as it now is, but... as it was 2 million years ago. So we experience as "simultaneous" the events on the boundary of our past ... But all timelike and lightlike curves converge upon the Omega Point. ...[L]ight rays from all people who died... from all... people now... from all [future] people... intersect there. The light rays... from people... are not lost forever... [T]hese rays will be intercepted and intercepted again, by the living beings who... engulfed the physical universe near the Omega Point. All the information which can be extracted from those rays will be extracted at the instant of the Omega Point."
