Two prominent researchers—Dr. Stuart Hameroff and Sir Roger Penrose—describe the human brain as a biological computer. They argue that consciousness operates like a program within a quantum computer housed in the brain, which persists beyond physical death. In their view, when a person dies, their soul does not vanish but instead returns to the universe.
For centuries, philosophers and scientists have debated whether the soul is immortal or perishes with the body. This enduring mystery still captivates various scientific fields. Recently, however, a team of researchers claims to have uncovered a new insight: the soul does not cease to exist; it merely returns to the cosmos.
Starting in 1996, Dr. Stuart Hameroff—an American physicist and professor emeritus in anesthesiology and psychology—along with Sir Roger Penrose, a mathematical physicist from Oxford University, have developed a Quantum Theory of Consciousness. Their model proposes that the soul resides within microtubules inside brain cells.
This provocative theory holds that brain cells house microtubules, which contain the human soul. Hameroff and Penrose view the brain as a biological computer, with consciousness functioning as a software program executed by an internal quantum computer—a program that endures even after death.
Moreover, the duo contends that human consciousness arises from quantum gravity effects occurring inside microtubules. They call this mechanism 'Orchestrated Objective Reduction' (Orch-OR).
According to their theory, during clinical death, the brain's microtubules lose their quantum state, yet the information they hold remains intact. Essentially, the researchers explain, upon death the soul disperses back into the universe rather than being destroyed.
Speaking to the Science Channel's Through the Wormhole documentary, Dr. Hameroff explained: when the heart stops beating and blood flow ceases, the microtubules lose their quantum state. However, the quantum information within them cannot be destroyed—it simply distributes and dissipates across the universe. If a patient is resuscitated and revived, that quantum information can re-enter the microtubules, leading the patient to report a near-death experience. If the patient is not revived and dies, it is possible that this quantum information persists outside the body, perhaps indefinitely, functioning as a soul.
This theory suggests that human souls are not merely interactions among neurons in the brain; they may have existed since the very beginning of time.
