Does the soul exist? Is there any scientific theory of consciousness that could accommodate such a claim? According to Dr. Stuart Hameroff, a near-death experience happens when the quantum information that inhabits the nervous system leaves the body and dissipates into the universe. Contrary to materialistic accounts of consciousness, Dr. Hameroff offers an alternative explanation of consciousness that can perhaps appeal to both the rational scientific mind and personal intuitions.
Consciousness resides, according to Stuart and British physicist Sir Roger Penrose, in the microtubules of the brain cells, which are the primary sites of quantum processing. Upon death, this information is released from your body, meaning that your consciousness goes with it. They have argued that our experience of consciousness is the result of quantum gravity effects in these microtubules, a theory which they dubbed orchestrated objective reduction (Orch-OR).
Consciousness, or at least proto-consciousness is theorized by them to be a fundamental property of the universe, present even at the first moment of the universe during the Big Bang. “In one such scheme proto-conscious experience is a basic property of physical reality accessible to a quantum process associated with brain activity.”
Our souls are in fact constructed from the very fabric of the universe – and may have existed since the beginning of time. Our brains are just receivers and amplifiers for the proto-consciousness that is intrinsic to the fabric of space-time. So is there really a part of your consciousness that is non-material and will live on after the death of your physical body?
Dr Hameroff told the Science Channel’s Through the Wormhole documentary: “Let’s say the heart stops beating, the blood stops flowing, the microtubules lose their quantum state. The quantum information within the microtubules is not destroyed, it can’t be destroyed, it just distributes and dissipates to the universe at large.
If the patient is resuscitated, revived, this quantum information can go back into the microtubules and the patient says “I had a near death experience”‘
He adds: “If they’re not revived, and the patient dies, it’s possible that this quantum information can exist outside the body, perhaps indefinitely, as a soul.”
This account of quantum consciousness explains things like near-death experiences, astral projection, out of body experiences, and even reincarnation without needing to appeal to religious ideology. The energy of your consciousness potentially gets recycled back into a different body at some point, and in the mean time it exists outside of the physical body on some other level of reality.
