🌌 We Know a Lot, But Certainly Not Everything

Modern science has transformed our understanding of reality. We can observe galaxies billions of light-years away, manipulate individual particles and watch activity inside the living human brain.

Yet one enormous mystery remains remarkably close to us:

consciousness itself.

We can measure what happens in the brain when someone sees red, falls in love, dreams, takes psilocybin or loses consciousness under anaesthesia.

But why does any of this produce a subjective experience?

Why isn't the brain simply processing information without there being someone inside who experiences it?

This is related to what philosopher David Chalmers famously called the "hard problem of consciousness."

And once we begin exploring that problem, we encounter some fascinating scientific experiments.

Some are extremely strong.

Some produce intriguing but inconclusive results.

And others have been transformed by the internet into claims the original experiments never demonstrated.

Let's separate them.

🍄 Psychedelics: When a Few Hours Can Change Years

Psilocybin is the psychoactive compound associated with certain psychedelic mushrooms. In the body, psilocybin is converted into psilocin, which strongly affects serotonin signalling, particularly involving the 5-HT2A receptor.

Researchers at Johns Hopkins and elsewhere have shown something remarkable.

Under controlled conditions, a single high-dose psilocybin experience can produce what participants describe as among the most personally meaningful or spiritually significant experiences of their lives.

Even more interestingly, some psychological changes can persist months or longer.

Research led by Roland Griffiths and colleagues found lasting changes in attitudes, mood and behaviour following profound psilocybin experiences.

Another study found lasting increases in the personality characteristic openness among participants who experienced particularly strong mystical-type effects.

Scientific status: 🟢 Strong evidence for profound psychological effects.

But there is an important boundary.

Science can demonstrate that someone experienced an extraordinary feeling of unity with the universe.

It cannot therefore conclude:

"The person actually became connected to the universe."

The experience is real.

The interpretation remains an open question.

🍄 Does Mycelium Connect More Than Plants?

Fungi form extraordinary underground networks.

Mycorrhizal fungi can physically connect with the roots of multiple plants. Water, nutrients and chemical compounds can move through fungal networks.

This has inspired the famous expression:

"The Wood Wide Web."

But popular culture sometimes exaggerates what science has demonstrated.

Fungal networks exist.

Material exchange through them exists.

However, claims that entire forests consciously "talk" to one another or that mother trees deliberately send messages to their offspring remain controversial.

And when humans consume psychedelic mushrooms, mycelium does not begin growing between their neurons.

Psilocybin acts pharmacologically on the human brain.

There is currently no evidence that mushrooms create a biological network connecting separate human brains.

Scientific status: 🟢 Fungal networks exist.

🔴 Human telepathy through mycelium is not demonstrated.

But the comparison inspires an interesting scientific question:

Could human brains ever be networked?

Surprisingly, they already have been.

🧠 Brain-to-Brain Communication Is Already Real

Researchers have experimentally connected human brains using technology.

One person's brain activity can be detected using EEG, processed by computers and transmitted to another person, whose brain is stimulated using technologies such as transcranial magnetic stimulation.

Experiments have even connected several people into primitive brain-to-brain networks.

This isn't telepathy.

There is technology in between.

But the principle is extraordinary:

Brain → computer → network → computer → brain.

Artificial intelligence could eventually become enormously important here.

Future AI might identify neural patterns too complicated for humans to decode and translate them into information another brain can understand.

Scientific status: 🟢 Demonstrated experimentally.

😴 Scientists Can Communicate With People While They Dream

This sounds like science fiction.

It isn't.

Researchers from several laboratories demonstrated two-way communication with people during REM sleep.

Some participants became lucid while dreaming, meaning they knew they were dreaming without waking up.

Researchers asked questions.

The dreamers processed those questions and sometimes answered correctly using predetermined eye movements or facial-muscle signals.

Some even answered simple mathematical questions.

This is different from sleepwalking, which occurs predominantly during non-REM sleep.

The fascinating implication is that someone can simultaneously inhabit an internally generated dream environment while still receiving and transmitting information to the external world.

Scientific status: 🟢 Reproduced experimental phenomenon.

It doesn't prove another dimension exists.

But it demonstrates how surprisingly flexible conscious reality can be.

❤️ Consciousness Around Death

Near-death experiences are considerably more complicated than internet stories sometimes suggest.

The AWARE II study investigated hundreds of cardiac-arrest patients.

Researchers attempted to measure brain activity during resuscitation and later interviewed survivors.

Some survivors reported structured experiences associated with the period surrounding their cardiac arrest.

Researchers also detected organised EEG activity during prolonged resuscitation in some patients.

Other research has observed bursts of highly organised brain activity in some dying patients.

This challenges the simplistic assumption that:

heart stops → brain instantly becomes completely inactive → nothing complex can happen.

However, it does not prove consciousness leaves the body.

Experiments involving hidden visual targets have so far failed to provide convincing evidence that patients could perceive information from outside their bodies.

Scientific status: 🟡 Extremely interesting, but no proof of consciousness existing independently of the brain.

👶 Children Who Remember "Previous Lives"

Researchers at the University of Virginia have investigated thousands of cases involving young children who spontaneously report apparent memories of previous lives.

Some cases contain surprisingly specific details later associated with deceased individuals.

That deserves investigation.

But there is a major scientific difficulty.

These aren't laboratory experiments.

Researchers must exclude information accidentally provided by parents, cultural influence, selective memory, coincidence and changes in stories over time.

Follow-up research has demonstrated that people's later recollections of what they supposedly said as children can differ substantially from what was originally documented.

Scientific status: 🟡 Fascinating cases exist; reincarnation has not been demonstrated.

The strongest future cases would be those where every statement is recorded before anyone searches for a matching deceased person.

🧠 Telepathy and the Ganzfeld Experiments

Ganzfeld experiments are among the more serious attempts to investigate telepathy.

A "sender" observes a randomly selected image.

Elsewhere, a "receiver" is placed in a state with reduced sensory stimulation.

The receiver later attempts to identify the target from several possibilities.

With four possible targets, random guessing should produce approximately:

25% accuracy.

Some collections of Ganzfeld experiments have reported results modestly above chance.

Meta-analyses have sometimes found statistically significant effects.

However, methodological issues, publication bias, randomisation procedures and difficulties obtaining consistently strong independent replication remain important problems.

Therefore:

Scientific status: 🟡 Interesting statistical anomaly, telepathy is not established.

And this distinction matters enormously.

Something can deserve further investigation without already being proven.

👁️ Remote Viewing and the CIA

Yes, this really happened.

The United States government funded research into remote viewing through programmes eventually associated with Project STARGATE.

Participants attempted to describe distant locations or objects without conventional access to them.

Some experiments appeared statistically interesting.

But after years of investigation, remote viewing failed to become sufficiently reliable for intelligence operations.

The programme was eventually discontinued.

So:

"The CIA investigated remote viewing." → TRUE.

"The CIA proved psychic spying works." → FALSE.

Scientific status: 🟡/🟠 Historically fascinating but insufficiently reliable.

⏳ Can Humans Sense the Future?

Several experiments have investigated precognition and "presentiment."

Psychologist Daryl Bem famously published experiments suggesting participants performed slightly better than chance when their behaviour appeared to be influenced by events selected randomly afterwards.

Other researchers attempted replication.

Several important preregistered replication attempts failed.

Separate presentiment experiments have reported tiny physiological differences occurring seconds before randomly selected emotional stimuli.

These findings remain controversial because extremely small effects can emerge from statistical methodology, filtering, trial ordering or analytical choices.

Scientific status: 🟠 Precognition is not convincingly demonstrated.

Interesting enough to investigate?

Absolutely.

Proven?

No.

💊 The Placebo Effect Gets Really Weird

The placebo effect is unquestionably real in certain contexts.

But one experiment makes it especially fascinating.

Researchers have given people placebo pills while explicitly telling them that the pills contain no active medication.

Surprisingly, some studies still found improvements in symptoms.

These are called:

Open-label placebos.

Expectation, conditioning, attention and the therapeutic context can apparently influence genuine aspects of subjective and physiological experience.

That doesn't mean:

"Positive thinking cures everything."

It doesn't.

But it demonstrates something profound:

Information → expectation → brain → bodily experience.

Scientific status: 🟢 Real and experimentally demonstrated, although effect sizes and usefulness depend heavily on the condition and context.

🧠 Split-Brain: Can One Brain Contain Two Minds?

In certain severe epilepsy cases, surgeons historically severed the corpus callosum, the enormous bundle connecting the brain's two hemispheres.

Experiments produced astonishing results.

Information presented exclusively to one hemisphere could sometimes influence behaviour even though the speaking hemisphere appeared unable to report seeing it.

One hand could select the correct object while the person verbally claimed not to have seen the relevant stimulus.

The phenomenon is real.

The interpretation remains debated.

Does splitting communication produce two separate consciousnesses?

Or one consciousness with radically separated access to information?

Scientific status: 🟢 Strong phenomenon; philosophical interpretation remains unresolved.

⚛️ Quantum Mechanics: Reality Really Is Strange

Here we need to remove a huge amount of internet nonsense.

Experiments involving Bell inequalities, quantum entanglement, delayed-choice arrangements and quantum erasers genuinely produce results that conflict with ordinary classical intuition.

Quantum correlations are real.

Entanglement is real.

Bell inequality violations are experimentally demonstrated.

Delayed-choice experiments are real.

But:

Human consciousness is NOT required for quantum measurement.

A detector is sufficient.

Therefore claims such as:

❌ "Quantum physics proves manifestation."

❌ "Thinking about something changes distant reality."

❌ "Quantum mechanics proves telepathy."

❌ "Human consciousness collapses reality because somebody looks at it."

are not conclusions established by these experiments.

Scientific status of quantum phenomena: 🟢 Extremely strong.

Scientific status of the mystical interpretations commonly attached to them: 🔴 Unsupported.

Ironically, quantum mechanics becomes more fascinating, not less, when we remove the exaggeration.

🌌 So Where Does This Leave Us?

Perhaps the biggest mistake is believing there are only two possible positions:

"Everything mysterious is nonsense."

or

"Everything mysterious proves a spiritual reality."

Science requires neither.

There is a much more interesting third position:

We accept what the evidence demonstrates, investigate anomalies seriously and remain comfortable saying "we don't know" when the evidence stops.

Some mysteries have disappeared because science explained them.

Others became even stranger after we measured them properly.

Quantum mechanics is an excellent example.

Consciousness may eventually become another.

🤖 Could Artificial Intelligence Change Everything?

This may become one of the most fascinating developments of the coming decades.

Human perception is limited.

Our brains evolved primarily to survive, reproduce and navigate our immediate environment, not necessarily to understand every structure existing in reality.

AI doesn't share exactly those biological limitations.

Future systems could potentially discover patterns in:

• brain activity,
• quantum experiments,
• astronomical signals,
• psychedelic brain states,
• communication networks,
• mathematics,
• physics,

that are simply too complex for humans to recognise unaided.

That does not mean AI will communicate with another dimension.

There is currently no evidence that such communication is possible.

But if something unusual exists within measurable data, increasingly powerful AI could become an extraordinary tool for finding it.

And if one day an AI claims:

"Something is communicating with us."

we shouldn't automatically believe it.

Nor should we automatically dismiss it.

We should ask the most important scientific question:

Can we reproduce it?

If independent laboratories can repeatedly receive information that cannot be explained through known channels, then something genuinely extraordinary has happened.

🔬 The Most Important Lesson: Mystery Is Not Evidence, But Mystery Deserves Investigation

There are phenomena we understand extremely well.

There are phenomena we partly understand.

There are statistical anomalies.

There are extraordinary personal experiences.

And there is also plenty of nonsense.

We shouldn't mix them together.

Psilocybin can profoundly change human experience. Proven.

Mycelium can connect plants. Proven.

Technology can transmit information between brains. Proven.

Lucid dreamers can communicate with researchers while sleeping. Proven.

Quantum entanglement exists. Proven.

Telepathy? Not proven.

Remote viewing? Not reliably demonstrated.

Reincarnation? Interesting reports, not proven.

Consciousness surviving death? Not proven.

Communication with other dimensions? No verified evidence.

But none of those last answers needs to mean:

"Impossible."

It means something much more scientifically responsible:

We don't know.

And perhaps that is where humanity's most interesting discoveries have always begun.

Not with blind belief.

Not with automatic disbelief.

But with curiosity, evidence, experiments and the willingness to change our minds when reality gives us a good enough reason.

Stay curious. Stay critical. And never confuse an unanswered question with an answered one. 🌌🔬
