The Everything Books: Planck Time

The Planck time is the smallest interval that physics can meaningfully describe. It emerges from the fundamental constants of nature, marks the collision of general relativity and quantum mechanics, and appears at the first moment of the universe. But is this a real boundary of reality or merely a limit of our measurement? This first volume of The Everything Books traces the history of the question from ancient atomism to modern quantum gravity. It explores the black hole barrier, the phenomenology of lived time, and the contemplative traditions—Advaita, Buddhism, Christian and Islamic mysticism—that point to a timeless now beyond all measurement. It examines the role of consciousness in physics and asks whether the observer can ever be separated from the observed. "Can you separate wetness from water"? Finally, it invites the seeker to see the Planck time not as a wall but as a door. The shortest tick of the cosmic clock opens onto the timeless presence that never ticks or changes at all.
