Postmortem Survival and the Physical Universe with Ruth Kastner (4K Reboot)

New Thinking AllowedAug 23, 2026

Philosopher of physics Ruth Kastner joins Jeffrey Mishlove to ask whether quantum theory leaves room for consciousness to survive bodily death. She rejects Einstein's 'block universe' consolation and argues instead for a quantum substratum, a real domain of possibility outside space-time from which physical events emerge. In her view, most of reality lies beyond space-time, which opens the door to mental or spiritual dimensions and to postmortem survival.
