"The theory implies that death of consciousness simply does not exist. It only exists as a thought because people identify themselves with their body. They believe that the body is going to perish, sooner or later, thinking their consciousness will disappear too. If the body generates consciousness, then consciousness dies when the body dies. But if the body receives consciousness in the same way that a cable box receives satellite signals, then of course consciousness does not end at the death of the physical vehicle. In fact, consciousness exists outside of constraints of time and space. It is able to be anywhere: in the human body and outside of it. In other words, it is non-local in the same sense that quantum objects are non-local.
Lanza also believes that multiple universes can exist simultaneously. In one universe, the body can be dead. And in another it continues to exist, absorbing consciousness which migrated into this universe. This means that a dead person while traveling through the same tunnel ends up not in hell or in heaven, but in a similar world he or she once inhabited, but this time alive. And so on, infinitely. It’s almost like a cosmic Russian doll afterlife effect."
