The Subjective Eternity Hypothesis (SEH)

This paper introduces the Subjective Eternity Hypothesis (SEH), a preliminary conceptual framework exploring how the human brain may construct experiences of extraordinary duration or timelessness. It investigates three proposed mechanisms: temporal expansion, retrospective memory reconstruction and subjective timelessness. DMT research and near-death experiences are examined as comparative domains for investigating altered temporal perception and consciousness. The paper presents research questions and testable predictions without claiming empirical validation or establishing the survival of consciousness after biological death.
