What If Science Has Not Disproved the Spiritual — It Simply Hasn’t Reached It Yet?
There is a phrase people use far too easily:
“Science has never proven that.”
Sometimes that is exactly the right objection.
But sometimes it hides a second assumption:
therefore, it does not exist.
Those two statements are not the same.
In January 2026, physicist Michael Guillén, who previously taught physics at Harvard, published an opinion article asking whether heaven might have a physical location beyond the cosmic horizon.
His argument immediately attracted attention because it combines two subjects that are usually kept apart: modern cosmology and spiritual belief.

But before accepting the headline at face value, an important distinction needs to be made.
Guillén did not scientifically discover heaven.
No telescope detected paradise.
No experiment identified a spiritual realm.
No peer-reviewed astronomical study established a physical address for heaven.
What Guillén published was an opinion essay in which he used real concepts from cosmology to build a philosophical and religious interpretation. Fox News
And that distinction is precisely what makes the discussion interesting.
What Is the Cosmic Horizon?
When we look into space, we are also looking into the past.
Light takes time to travel.
The farther away an object is, the longer its light has taken to reach us.
Because the Universe has a finite age and is expanding, there are limits to how much of it we can observe.
Cosmology therefore works with different kinds of cosmological horizons — boundaries related to which regions of the Universe can send information to us now or ever in the future.
This is real physics.
What lies beyond the observable Universe is not necessarily nonexistent.
It is simply beyond what we can currently observe directly.
That distinction matters enormously.
Where Guillén Takes the Next Step
Guillén goes beyond the scientific concept itself.
He asks whether what religious traditions describe as heaven could exist beyond this cosmological boundary.
In his essay, he connects biblical descriptions of heaven with ideas about the expansion of the Universe and the cosmic horizon. Fox News
That is where science ends and interpretation begins.
His proposal may be provocative.
It may be philosophically interesting.
But it is not an established conclusion of cosmology.
And we think it is important to say that clearly.
Because respecting spirituality does not require pretending that a hypothesis has already been scientifically demonstrated.
But There Is Another Mistake We Should Avoid
The opposite mistake is equally common.
It sounds like this:
“Science cannot detect it, therefore it does not exist.”
That conclusion is also unjustified.
Science investigates reality through observation, measurement, experimentation, mathematical models, and instruments.
But those instruments change.
Those models change.
Our ability to observe changes.
Reality does not wait for humanity to invent the equipment required to detect it.
Microorganisms existed before microscopes.
Radio waves existed before antennas.
The structure of DNA existed before molecular biology.
Black holes existed long before we obtained strong observational evidence for them.
The absence of a measuring instrument never prevented a phenomenon from existing.
This does not mean that every spiritual claim is therefore true.
It means something more disciplined:
absence of evidence is not evidence of absence.
What If Some Spiritual Questions Are Questions of Measurement?
For students of spirituality, this possibility is difficult to ignore.
Human cultures have described heaven, hell, other dimensions, invisible realms, altered states of consciousness, and realities beyond ordinary perception for thousands of years.
Today, science does not provide empirical evidence that these descriptions correspond to literal physical realms.
That should be acknowledged.
But another question remains open:
Could some phenomena that we currently classify as spiritual eventually become accessible to scientific investigation?
We believe this possibility deserves serious consideration.
Not because spirituality should be disguised as science.
And not because scientific standards should be weakened.
Quite the opposite.
If such phenomena exist objectively, the most interesting future would be one in which better tools allow us to investigate them rigorously.
Science Has Always Expanded Its Territory
Many phenomena once surrounded by mystery eventually moved into scientific territory.
Lightning was once interpreted through mythology.
Disease was frequently attributed to supernatural causes.
The movement of planets was embedded in religious cosmologies.
The invisible world of microorganisms was completely inaccessible to human perception.
Today, these phenomena belong to physics, biology, astronomy, and medicine.
Their scientific explanation did not make them less extraordinary.
In many cases, it made them even more astonishing.
This is why we are cautious about declaring that the current boundaries of science represent the final boundaries of reality.
History gives us little reason for that confidence.
Our Perspective at D.O.S. Disks
Our interest is not in proving beliefs.
It is not in claiming that cosmology has discovered heaven.
And it is not in using scientific vocabulary to give spiritual ideas an appearance of proof they have not earned.
Our interest lies in the frontier.
The frontier between what can already be measured and what cannot.
Between established knowledge and open questions.
Between human experience and the instruments available to investigate it.
For those who study spirituality, realities described as different levels, states, dimensions, or vibrational layers may represent territories that science has not yet developed the language or technology to investigate.
At present, that remains a philosophical and spiritual interpretation.
But we see no reason to assume that the boundary must remain permanent.
Being Open-Minded Does Not Mean Believing Everything
There is an important difference between intellectual openness and credulity.
Being open to new possibilities does not mean accepting every extraordinary claim.
A serious investigator should remain open to hypotheses while demanding increasingly strong evidence.
The same principle applies in both directions.
We should not say:
“It has not been scientifically explained, therefore it must be spiritual.”
But we should also be cautious about saying:
“Science cannot currently measure it, therefore it cannot exist.”
Both positions go beyond the available evidence.
The more interesting space lies between them.
Perhaps Science and Spirituality Are Not Permanent Opposites
For centuries, science and spirituality have often been presented as competing ways of describing reality.
But perhaps that division is partly historical.
Science specializes in what can be observed, measured, modeled, and tested.
Spiritual traditions have often explored questions of meaning, consciousness, experience, mortality, and realities beyond ordinary perception.
There may be areas where the two never overlap.
But there may also be areas where future discoveries change the vocabulary of the discussion entirely.
What we currently call “spiritual” might remain spiritual.
Or some parts of it might eventually acquire measurable correlates, new physical descriptions, or entirely new scientific frameworks.
We simply do not know yet.
And admitting that is not a weakness.
It is one of the foundations of genuine inquiry.
So, Did Michael Guillén Find Heaven?
No.
And the headlines suggesting that he did are much more dramatic than the actual content of his argument.
What he offered was a speculative interpretation connecting a real cosmological concept with a religious idea. Fox News
But that does not make the discussion worthless.
In fact, it raises a question we find far more interesting than the headline itself.
Humanity has repeatedly discovered that reality was larger, stranger, and more complex than previous generations imagined.
So perhaps the real question is not whether we should accept every spiritual explanation today.
The better question is:
Which spiritual mysteries of today will become scientific phenomena tomorrow?
