What Is Real

How do we know what is real? This dig starts with a simple one, how old things are and how we can tell. Then it follows the money behind the doubt. Then it turns around, toward Plato’s cave, consciousness, quantum physics, and what the mind can and cannot do.

Why this page exists

This is my place to dig into the stuff that matters. I pick a hard question, read the sources myself, follow the money, and write down what I find in plain words.

I could be wrong, so everything is linked. Check me. All the digs are at The Digs. Next door: Ethics, on Gaza and preserving life.

The methodHow carbon dating works

1The sky makes itCosmic rays hit nitrogen high in the air and turn a little of it into carbon 14, a slightly heavy, unstable carbon.
2Life takes it inPlants breathe it in. Animals eat the plants. Every living thing carries the same tiny share: about one carbon atom in a trillion.
3Death stops the clockWhen the thing dies it stops taking in carbon. The carbon 14 it already has decays back to nitrogen at a fixed pace.
4We count what is leftA machine called an AMS counts the atoms one by one in a sample the size of a grain of rice. Half gone means 5,730 years.
100%50%25%12.5% 05,73011,46017,19022,920about 50,000 years almost nothing left to countyears since death

After about nine half lives less than a fifth of one percent is left. That is why the method stops near 55,000 years, and why it could never say “millions” about anything.

Willard Libby worked this out in 1949 and won the Nobel Prize in 1960. His first tests were on things with known dates, such as wood from Egyptian tombs. It matched.

A false balance is abomination to the Lord: but a just weight is his delight.
Proverbs 11:1

The honest answerIs it the best thing we have?

For its own job, yes. For other jobs, no, and nobody claims otherwise.

Where it is strong

  • Bone, wood, charcoal, cloth, seeds, shell, up to about 55,000 years
  • Usually good to within a few decades for the last several thousand years
  • Checked against things we can count by hand, year by year
  • Run blind in rival labs around the world that would love to catch each other out

Where it is weak, and scientists say so

  • Old carbon in water. Shellfish and river animals take in ancient carbon from limestone and look too old. Known since 1963. Corrected for.
  • Contamination. A trace of modern carbon makes very old samples look younger. This sets the 55,000 year ceiling.
  • The sky is not steady. Carbon 14 in the air has risen and fallen. That is why every date is calibrated.
  • Our own mess. Coal smoke and 1950s bomb tests changed the air. Both are measured and accounted for.

How the calibration is done

Scientists did not assume the past was steady. They went and measured it. The current standard is called IntCal20.

Natural calendarHow it is countedHow far back
Tree ringsOne ring a year, matched tree to tree, each ring carbon dated13,900 years
Lake Suigetsu, JapanOne thin layer of mud a year, with leaves trapped insideabout 50,000 years
Cave stone and coralDated two ways at once, by carbon and by uranium55,000 years
Greenland and Antarctic iceOne layer of snow a year, counted by hand and by machine60,000 counted, 800,000 in total

A tree ring does not care about anyone’s theory. Neither does a layer of mud. They all tell the same story.

Past the limitHow we date things older than 55,000 years

Carbon 14 is a fast clock. It runs down in a few tens of thousands of years, like a kitchen timer. For older things you need slower clocks, and nature supplies them. The idea is the same every time: an unstable parent atom turns into a stable daughter atom at a fixed pace. Count both and you know how long the clock has been running. Think of an hourglass. Sand on top, sand on the bottom, and a neck that never changes width.

ClockWhat it datesReach
Carbon 14Things that were once aliveto 55,000 years
LuminescenceThe last time a grain of sand saw sunlight, or a pot was firedto about 300,000 years
Uranium to thoriumCoral and cave stoneto about 500,000 years
Potassium to argonVolcanic ash and lava. Half life 1.25 billion years100,000 years to billions
Rubidium to strontiumAncient rock, Moon rock, meteorites. Half life 49 billion yearstens of millions to billions
Uranium to leadZircon crystals. Two clocks in one: 4.47 billion and 704 million yearsa million years to the age of the Earth

The three fair questions, answered

?

“How do you know how much daughter was there at the start?”

Good question, and geologists asked it first. Two answers. Zircon crystals take in uranium when they form but push lead out, so the lead clock starts at zero. And the isochron method measures several minerals from one rock and plots them on a line. The slope gives the age and the line itself tells you how much daughter was there at the start. Nothing has to be assumed.

?

“What if atoms leaked in or out?”

Then the clocks disagree, and that is how you catch it. Uranium gives two separate clocks inside the same crystal. If they match, nothing leaked. If they do not, the sample is thrown out. Rocks are also dated by several different elements at once. Leaks would not fool them all by the same amount.

?

“What if decay ran faster in the past?”

These clocks run on three different kinds of decay with different physics. To keep them in agreement, each would have had to speed up by a different amount, in step, and then the heat would have melted the planet. And we can look at the past directly: the exploding star seen in 1987, 168,000 light years away, shows decay running at today’s pace.

Tested against a date we already know

In 1997 a Berkeley team used the argon method on ash from the eruption that buried Pompeii. They did not tune it to the answer. The clock said 1,925 years, give or take 94. Pliny the Younger watched that eruption and wrote it down: AD 79, which was 1,918 years before the test. A method built for millions of years hit a known date within seven years. Renne and others, Science, 1997

Checks that have nothing to do with atoms

years: the oldest crystal on Earth, a zircon from Australia
The age of the Earth, 4.54 billion years, comes from lead in meteorites, first measured by Clair Patterson in 1956 and confirmed since with different elements in different labs. The oldest Earth rock still standing is about 4 billion years old, in northern Canada. The oldest crystal is 4.4 billion. Carbon 14 has nothing to do with any of it. US Geological Survey, Age of the Earth · the 4.4 billion year zircon

The strength of all this is not any one clock. It is that clocks built on different physics, plus coral, ice, mud and a spreading ocean, were free to disagree and did not.

The attacksSeven mistakes, and what is true

I am not calling anyone a liar. I am listing claims that have been checked and did not hold up. Each one links to the evidence, and where I can, to the ministry’s own words.

1
Straw man

“Carbon dating is how they get millions of years.”

It is not, and it cannot be. The method runs out at 55,000 years. Dinosaur bones and rock layers are dated with the other clocks above. Attacking carbon dating to defend a young Earth is aiming at the wrong target.

2
Cherry picking

“A living snail was dated at 27,000 years old.”

True, and scientists are the ones who found it and explained it, in the journal Science, in 1984. The snails lived in spring water full of dissolved ancient limestone. That is the old carbon effect, known since 1963 and corrected for. A known limit written on the label is not a hidden flaw.

3
Misread instrument

“There is carbon 14 in coal and diamonds, so they must be young.”

This was the headline of ICR’s RATE project. Every machine has a noise floor, like the hiss of a speaker turned all the way up. Radiocarbon labs put diamonds in their machines on purpose, to measure that hiss. The faint signal is the machine and traces of contamination, not the diamond. The clearest rebuttal was written by Kirk Bertsche, a Christian physicist who helped build these machines.

Wrong tool

“Lava from Mount St. Helens in 1986 was dated at 350,000 years.”

A creation geologist sent ten year old rock to a lab whose own paperwork said its equipment could not measure anything younger than two million years. The sample also held old crystals carried up from deep below. Weighing a letter on a truck scale and getting the wrong answer says nothing about the scale.

Summary of the case · Henke’s full critique · ICR’s paper

Out of date

“It assumes carbon 14 in the air was always the same.”

Libby assumed that in 1949. By the 1960s tree rings had shown otherwise, and every date since has been calibrated. The objection is sixty years stale.

IntCal20, the current calibration

Self defeating

“Radioactive decay ran a million times faster during the Flood.”

This is ICR’s answer to all the older clocks. Their own team admitted the problem: that much decay in one year releases enough heat to boil the oceans and melt the crust, and enough radiation to kill everything on the Ark. ICR lists this as unresolved on its own website. Their answer so far is that God must have removed the heat by a miracle, which is no longer a scientific claim.

Answer first

The conclusion is fixed before the evidence is looked at.

Answers in Genesis requires its staff to sign a statement of faith that says no evidence in any field “can be valid if it contradicts” their reading of Scripture. Whatever else that is, it is not research. A scientist who signed the mirror image of that statement would be laughed out of the room, and should be.

AiG Statement of Faith
He that is first in his own cause seemeth just; but his neighbour cometh and searcheth him.
Proverbs 18:17

Follow the moneyWho gets paid, and for what

Young earth ministries often say scientists defend old ages to protect their grants. Fair enough. Let us look at everyone’s books. Theirs are public, because they are tax exempt.

The creation ministries
About $84 million a year
for just the two largest, plus about $165 million in buildings
Answers in Genesis, yearly revenue (latest IRS filing)$73.5 M
Institute for Creation Research, yearly revenue (2025). 83% is donations$10.4 M
Ken Ham, chief executive pay and benefits$291,000
Ark Encounter theme park, built$100 M+
ICR Discovery Center, Dallas, built$37.8 M
Creation Museum, Kentucky, built$27 M
ICR’s RATE project, all donor moneyabout $2 M

The product is doubt. The income is donations, tickets, books, videos and homeschool curriculum. If carbon dating is right, the product has no market.

The scientists
$300 to $500 a sample
is what a university lab charges to run a carbon date, whatever the answer is
Who paysGrants, museums, builders, police, wine and art fraud cases
Does the lab earn more for an old date?No
What makes a scientist famous?Proving the textbook wrong
Who bets real money on old Earth geology?Every oil company on Earth

Scientists have money motives too: grants, jobs, pride. But the payoff in science runs toward overturning things. Anyone who could show radiometric dating is broken would win a Nobel Prize and never pay for lunch again.

The taxpayer’s share of the Ark

$62 M
in bonds issued by the town of Williamstown, Kentucky to build it
75%
of its property tax for 30 years goes to pay off its own loan
$1.8 M
a year in state sales tax handed back
98 acres
of land plus $175,000 given by the county

The test that settles it

Ask who gets paid only if the answer comes out one way. A dating lab is paid the same for any result. An oil company loses billions if its geology is wrong, and not one of them drills using Flood geology. A young earth ministry is paid only if the Earth stays young. Glenn Morton was a young earth creationist who went to work finding oil. The rocks he saw every day broke his view, and it nearly broke his faith. He kept the faith and let go of the young Earth. His story, in his own words.
For the love of money is the root of all evil.
1 Timothy 6:10 · it applies to laboratories and ministries alike

A note for ChristiansYou do not have to choose

The young Earth reading became a test of faith in America only in the 1960s. Long before Darwin, Augustine warned Christians not to talk nonsense about the natural world in the name of Scripture, because unbelievers who knew better would then laugh at the Gospel too. Many believers who date rocks for a living see no conflict at all.

The heavens declare the glory of God; and the firmament sheweth his handywork.

Psalm 19:1

For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made.

Romans 1:20

One day is with the Lord as a thousand years, and a thousand years as one day.

2 Peter 3:8

It is the glory of God to conceal a thing: but the honour of kings is to search out a matter.

Proverbs 25:2

If creation is God’s handiwork, then tree rings and atoms are his testimony as well. A God who planted false ages in the rocks would be a deceiver, and that is not the God of the Bible.

The bigger questionShadows on a cave wall

About 2,400 years ago Plato told a story. People sit chained in a cave, facing the back wall. Behind them is a fire, and between the fire and their backs other men carry puppets. All the prisoners ever see is shadows, so they take the shadows for the world. They hand out prizes to whoever is best at predicting the next one. One prisoner gets free, turns around, sees the fire, climbs out, and is blinded by the sun. When he comes back down to tell the others, they laugh at him and would kill him if they could.

The fight over the age of the Earth is a shadow fight. A number on the wall, 6,000 or 4.5 billion, with people behind us holding up the puppets, and as the money section shows, selling tickets to the show.

Turn around and the questions get much bigger. Why is there anything at all? And the strangest fact any of us knows: somebody is home. You are not only a body that reacts. There is something it is like to be you, to see red, to grieve, to love your child. A 6,000 year old Earth does not explain that. A 4.5 billion year old Earth does not explain it either. So I kept digging, below.

That is where the real mystery lives, and it is where faith and philosophy have always done their best work. It is a poor trade to spend a life defending a number and never look at the light.

Turn aroundSomebody is home. But where?

Here is the strangest fact you know. There is something it is like to be you. Red looks like something. Grief weighs something. Science can trace every signal in your brain and still cannot say why any of it comes with an inner light instead of running in the dark. The philosopher David Chalmers named this the hard problem, and asked it in one line: why should physical processing give rise to a rich inner life at all?

Is it even inside your head?

View one: the brain makes it

The standard view, with real evidence behind it.

  • Anesthesia switches you off. Coffee, wine and a blow to the head all change who is home.
  • Damage one spot and you lose faces. Another spot, and you lose words.
  • Cut the bridge between the two halves of the brain and each half acts like it has a mind of its own.

View two: the brain receives it

Older than it sounds. William James of Harvard argued it in 1898.

  • Smash a radio and the music stops. That does not prove the music was made inside the radio.
  • Every fact on the left fits a receiver just as well as a generator.
  • James called it the transmissive function. Aldous Huxley called the brain a reducing valve. Some physicists went further and said mind comes first.

Nobody has settled this. Anyone who tells you it is settled, in either direction, is selling something. What I can tell you is that the people who built modern physics did not think the question was silly.

The experiment that broke common sense

NOBODY CHECKS WHICH SLIT A DETECTOR CHECKS WHICH SLIT stripes: it went through both, like a wave two bands: it went through one, like a bullet

Fire electrons at a wall with two slits in it, one electron at a time. On the screen behind, they pile up in stripes. Stripes are what waves make, when a wave goes through both slits and overlaps with itself. So each single electron somehow went through both.

Now put a detector at the slits to see which one it really goes through. The stripes vanish. You get two plain bands, as if the electrons were little bullets all along. The act of finding out changes what happens. Richard Feynman said this one experiment holds “the only mystery” of quantum mechanics.

Where I have to be honest. You will hear that this proves your mind creates reality. It does not show that. The detector kills the stripes even if no person ever reads it. What matters is that a record of the path exists somewhere, not that a human is watching. What the experiment does show is stranger and better established: until something pins it down, the electron does not have one definite path. The world underneath is made of possibilities that become facts. Nobody knows exactly where or how that happens. Physicists call it the measurement problem, and after a hundred years they still vote differently on the answer.

The ways physicists have tried to tie it to mind

Consciousness is how information is woven togetherGiulio Tononi, Christof KochA leading theory in neuroscience, and hotly fought over.

Not in one place

The 2022 Nobel Prize in Physics went to three men who proved something Einstein could not stomach. Two particles that once touched stay linked. Measure one and the other answers at once, across any distance, with no signal passing between them. The experiments closed every loophole. At the bottom, nature is not local. That does not prove your mind is spread across the universe. It does knock out the old assumption that everything real must sit in one spot. Nobel Prize 2022

The people who kept asking

I regard consciousness as fundamental. I regard matter as derivative from consciousness.

Max Planck · father of quantum theory · 1931

Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental.

Erwin Schrödinger · Nobel Prize 1933

It was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.

Eugene Wigner · Nobel Prize 1963

No phenomenon is a real phenomenon until it is an observed phenomenon.

John Archibald Wheeler

The stuff of the world is mind stuff.

Sir Arthur Eddington · 1928 · the man who proved Einstein right

The universe begins to look more like a great thought than like a great machine.

Sir James Jeans · 1930

We are not required to think of productive function only; we are entitled also to consider permissive or transmissive function.

William James · Harvard · 1898 · on the brain and thought

The most beautiful thing we can experience is the mysterious.

Albert Einstein · 1930

Man is but a reed, the most feeble thing in nature; but he is a thinking reed.

Blaise Pascal · Pensées

The unexamined life is not worth living.

Socrates · at his trial, 399 BC
For in him we live, and move, and have our being.
Acts 17:28 · Paul in Athens, quoting a Greek poet to Greek philosophers

Read that verse again next to Planck. Paul did not tell the philosophers that mind lives inside matter. He told them all of it lives inside Mind. Genesis says man became a living soul when God breathed into dust. The oldest claim of the faith is that consciousness came first and the dust came second. Quantum physics has not proved that. It has made it a respectable thing to wonder about again.

Mind over matterWalking through walls

Every culture tells of people who did the impossible by mastery of the mind. Tibetan and Taoist masters said to pass through rock. Indian yogis whose ancient handbook, the Yoga Sutras, lists powers like walking on water as things that show up along the way. And the Bible: the risen Christ standing among the disciples “the doors being shut” (John 20:26), and Peter walking on the sea until he looked at the waves and doubted.

What should an honest digger do with that? Sort it into three piles.

Pile one: measured in a lab

+15°F
Tibetan monks raised the temperature of their fingers and toes by meditation alone. Harvard, 1982
Fake
knee surgery worked as well as the real operation. Patients walked better for two years
Trained
volunteers turned down their own immune response on command, once thought impossible
Bigger
London cab drivers grew the memory part of their brains by learning the streets

For as he thinketh in his heart, so is he.

Proverbs 23:7

Be ye transformed by the renewing of your mind.

Romans 12:2

Pile two: claimed, never shown

Nobody has ever walked through a wall under conditions where cheating was ruled out. People have tried hard to find it. The CIA and the US Army spent about $20 million over twenty years on psychic research, the Stargate Project. One Army general, Albert Stubblebine, truly believed he could pass through his office wall and kept running at it. He kept hitting it. The program was shut down in 1995 after reviewers found nothing the government could use. The CIA’s declassified Stargate files

Here is the twist. Particles really do walk through walls. It is called quantum tunneling. It is how the Sun burns, and it is how the memory chip in your phone works. A wall is almost entirely empty space, held solid by electric force. So why can you not do it? The odds shrink with every particle added, and you are about seven billion billion billion particles that would all have to make it at the same instant. The chance is not zero. It is a number so small the universe is not old enough to see it happen once. Physics does not forbid the miracle. It prices it.

That is why I do not sneer at the locked room in John 20. If it happened, it was not a trick of technique that a monk could learn. It was the Author stepping through his own page. A miracle is by definition the thing the clocks and the odds cannot produce. That is what the word means.

Pile three: sold to you

The book The Secret sold over 30 million copies telling people the universe rearranges itself around their wishes and citing quantum physics to prove it. Quantum physics says no such thing. Seminars, crystals, and “quantum healing” courses are a multi billion dollar business. Same rule as the rest of this page: ask who gets paid only if you believe it. The monks in pile one never sold a ticket.

So can the mind shape reality?

It shapes your body, measurably. It shapes your brain, physically. It shapes your life, because a person who believes he can acts, and action moves the world. Faith the size of a mustard seed has in fact moved mountains, with shovels, in the hands of people who would not quit. Whether mind reaches further than that, into matter directly, is an open question that honest people should keep open, without paying anyone for the answer.

If thou canst believe, all things are possible to him that believeth.
Mark 9:23
For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
1 Corinthians 13:12 · Paul, who knew his Plato

So test the dates, because truth matters and a just weight is God’s delight. Then put the ruler down. The weightier matters were never how old the ground is. They are what we do while we stand on it: do justly, love mercy, and preserve life.
