Spirituality in Scientific Language — What Is Science and What Is Metaphor? The Quantum Observer, Holographic Universe, Synchronicity, Near-Death Experiences, the Pineal Gland and the Age of Aquarius

Metaphors are fine — calling them evidence is not

Scientific terms make spiritual ideas sound impressive. But scientific concepts hold under specific conditions. Taken out of those conditions they become metaphors, and using metaphors as evidence causes confusion. This article sorts eight common examples into “what science says” and “how spirituality borrows it.”

Quantum mechanics and the observer effect

• Science says: in quantum mechanics, “observation” or “measurement” means a physical interaction with a measuring device or the environment, not human consciousness. Physicist John Bell even criticised the word “measurement” itself for inviting misunderstanding (Bell, 1990).
• Spirituality borrows it as: “thoughts and consciousness create reality.”

That thoughts change actions and actions change lives is explained well enough by psychology; there is no need to invoke quantum mechanics.

The holographic universe and Indra’s net

• Science says: the holographic principle is a hypothesis in theoretical physics that the information in a region of space can be encoded on its boundary (‘t Hooft, 1993; Susskind, 1995). It is a mathematical idea from research on black holes and quantum gravity.
• Spirituality borrows it as: “everything is connected,” read alongside Indra’s net from the Buddhist Avatamsaka Sutra — a net in which each jewel reflects all the others.

Indra’s net is a beautiful philosophical image, but the holographic principle in physics does not prove it.

Synchronicity: Jung and Pauli

• Historically: psychologist Carl Jung, in dialogue with physicist Wolfgang Pauli, called meaningful coincidences without causal connection synchronicity (Jung & Pauli, 1952).
• Scientifically: coincidences happen more often than we expect, and we remember meaningful ones better. No experiment has confirmed synchronicity.

Using meaningful coincidences as prompts for reflection is fine; there is no basis for declaring them signals from the universe.

Near-death experiences

• Science says: some people revived from cardiac arrest report light, tunnels or leaving the body. A large study (AWARE) documented such reports, but no case was confirmed of someone “out of body” seeing images hidden above the bed (Parnia et al., 2014). Research has also found brief surges of strong brain activity in dying rats (Borjigin et al., 2013).
• Spirituality reads them as: evidence of an afterlife.

Near-death experiences are real and powerful. What they mean remains an open question.

The pineal gland and the “third eye”

• Science says: the pineal gland is a small endocrine organ deep in the brain that produces melatonin, helping regulate sleep rhythms. It commonly calcifies with age.
• Spirituality borrows it as: since Descartes called it the “seat of the soul” in the 17th century, it has been called the “third eye” or a source of DMT. The claim that the pineal gland produces spiritual experiences remains a hypothesis (Strassman, 2001).

Quantum biology and “vibrating hormones”

• Science says: quantum biology is a real field. It studies cases where quantum effects play a role in biology, such as energy transfer in photosynthesis and magnetic sensing in migratory birds (Lambert et al., 2013).
• Spirituality extends it to: “hormones are vibrations” and “healing the body with frequencies.” No research supports these claims.

Linking epigenetics to “karma” is similar. What epigenetics actually says is summarised in Health Buzzwords, Rechecked.

AI and the soul

• Science and philosophy say: why consciousness comes with subjective experience is known as the “hard problem of consciousness” and remains unsolved (Chalmers, 1995). Whether machines can be conscious is an open question.
• Spirituality extends it to: whether AI can attain enlightenment or a soul.

The Age of Aquarius and Spiral Dynamics

• The Age of Aquarius: an astrological “age” concept based on precession, in which the equinox point shifts by one constellation roughly every 2,150 years. There is no agreed start date; it was popularised by the 1960s counterculture.
• Spiral Dynamics: a model by Beck and Cowan (1996), based on psychologist Clare Graves’s research, that arranges human consciousness into developmental stages. It is used as a framework for understanding organisations and cultures, but empirical validation is limited.

Summary at a glance

Term	What science says	Spiritual metaphor
Observer effect	Physical interaction with a measuring device	Consciousness creates reality
Holographic universe	A mathematical hypothesis in quantum gravity	Everything is connected (Indra’s net)
Synchronicity	No experimental evidence; memory bias	Meaningful signals from the universe
Near-death experience	Genuinely reported; meaning open	Evidence of an afterlife
Pineal gland	Melatonin-producing organ	The third eye
Quantum biology	Quantum effects in some biological processes	Vibration and frequency healing
Age of Aquarius	An astrological concept based on precession	A new age of consciousness

Spiritual metaphors can help us reflect on our lives. Just check once more whenever “science has proven it” is attached.
