He states that, based on what we know and the speed of light constraint, contact or detection of alien civilizations remains improbable. Still, he concedes that in an infinite universe, some regions could be billions of years ahead or behind us, rendering contact unlikely but not impossible.
He also considers the possibility of quantum entanglement and other theoretical means of communication but notes these do not currently enable faster-than-light observation, and their practical utility is speculative.
