Tannhaus in “Unfinished Business”

As humans, we struggle to accept our own mortality. One holds onto events that are long gone. We long in vain for a way to turn back time...to reverse death. But when time is relative and nothing really ever passes, and the simultaneous overlapping of different realities is possible, shouldn't it then also be possible to bring back something that was believed to be dead long ago and to create a new reality in which the dead live again? If our life is defined as everything between birth and death, it exists there ad infinitum. Could we succeed in cheating death by finding a way to bring back life? There, in between time.
