I’m a sucker for time travel stories. I grew up watching Seven Days (1998–2001), and it was one of the first shows of its type to really pull me in. The premise was simple: a classified U.S. program could send one man exactly seven days into the past to prevent any number of disasters. That man was Frank Parker, played by Jonathan LaPaglia. An episode usually opened with a terrorist attack or a political assassination, something with real gravity and stakes, and then the NSA would initiate “Project Backstep” to fix it.
Quantum physics gets pulled in as a kind of catch-all justification. Because it deals with probabilities and strange behavior at small scales, it gets stretched into a license for almost anything.
What made it work, at least when it was firing on all cylinders, was that the seven-day limit forced the story to respect cause and effect. Frank couldn’t just roam freely throughout history. He had a narrow window, incomplete information, and operated under the constant risk that changing one thing might actually ripple into something worse. The show leaned into that tension, and made for some of the most intense and feverish hours of American television in the years leading up to 24.
When done well, time travel stories can feel inevitable. Choices matter, consequences are real, and the story locks into place with an immensely satisfying logic. But a lot of them (probably most of them) aren’t done well. They tend to fall apart the moment you start asking some pretty simple questions.
By way of example, let’s take the classic “grandfather paradox.” Most of us have seen some version of this time travel trope, in which a man travels back in time to prevent his grandfather from ever having children. If that happens, the man is never born. But if he’s never born, then he can’t go back in time to prevent his grandfather from having children. So what actually happens? The story is usually content to rest with that glaring contradiction, simply ignoring the problem and quickly moving on.
That’s the issue. Time becomes a hallway you can wander up and down, but the consequences of changing things in that hallway aren’t really thought through. Cause and effect—one of the most basic structures of reality—gets treated like something optional. Characters might alter the past, but they themselves remain unchanged. Entire timelines are rewritten, but somehow memory, identity, and history remain conveniently intact for the sake of the plot.
And when the story starts to strain under that weight, someone eventually says words like “quantum” or “multiverse” as if that settles anything.
To be clear, it doesn’t.
But those words do a lot of work in the minds of the audience, because they have become a kind of cultural shorthand for saying “reality is weird,” and while there’s a grain of truth to that, it has produced a lot of confusion. You’ll hear explanations like, “Well, when he changed the past, he created a new timeline,” or, “In another universe, the original version of him still exists.” That sounds like an answer, but it’s really just a way of moving the problem somewhere else. Anybody paying attention recognizes that you haven’t resolved the contradiction; in fact, you’ve multiplied it. Because now you have to explain what a “timeline” actually is, how these realities relate to each other, and why a person can move between them without unraveling the very conditions that produced him.
Quantum physics gets pulled in at this point as a kind of catch-all justification. Because it deals with probabilities and strange behavior at small scales, it gets stretched into a license for almost anything: alternate timelines, infinite versions of ourselves, reality shaped by observation in a sweeping, almost magical sense.
Christians don’t need to panic about that, but they shouldn’t ignore it either. If people are forming their basic sense of what reality is from a distorted picture of science, particularly one where contradictions are waved away and causality can be rewritten without consequence, then there are real implications for that. It affects how they think about truth, about responsibility, about whether choices actually matter, and ultimately about whether reality itself has a stable, intelligible structure grounded in something beyond us.
We should probably start with what quantum physics actually is and what it is not.
Most of what we instinctively think of as “how the world works” comes from what’s called classical physics, the framework associated with Isaac Newton and later refined by Albert Einstein. In that world, things behave in ways that make intuitive sense. Objects have definite locations. Causes produce predictable effects. Time moves forward in an orderly way. Even when Einstein complicates the picture with his general theory of relativity—showing that time can stretch or compress depending on speed and gravity—he is still describing a universe that is coherent. Space and time are woven together into a single fabric (spacetime), but it is still a fabric. It bends, it flexes, but it does not dissolve into ambiguity.
Quantum physics does not mean reality is arbitrary. It does not mean we create the world with our thoughts. It just means that… reality is structured in ways that do not fit neatly into the categories we developed from everyday experience.
Quantum physics, however, operates at a completely different scale, and at that scale, the rules don’t just become more complicated, they actually become less familiar. Instead of certainty, you get probability. Instead of definite positions, you get ranges of possible locations. Instead of observation simply revealing what is already there, observation becomes part of the system itself. The famous double-slit experiment is the clearest example. When a beam of light is observed passing through double-slits in a screen, the electrons behave like waves, spreading out and interfering with themselves. When you try to measure them and pin down where they are, electrons behave instead like particles. The outcome depends, in part, on the way you ask the question.
If that sounds abstract, it helps to think in terms of how you would track something in everyday life. Imagine trying to follow a baseball through the air. In the everyday world, if you throw a baseball, it travels along a single path. Even if you close your eyes, you assume it is always in one specific place at each moment, even if you might not know exactly where. Now imagine a very strange kind of baseball. When you throw it, it doesn’t follow one clean path. Instead, it spreads out into a whole range of possible paths at once, like a cloud tracing every route it could take. As long as you leave it alone, it behaves like that spread-out cloud. But the moment you try to check where it is—say you put a glove out to catch it—you get one solid baseball in one definite spot.
Quantum physics says that, at very small scales, particles behave more like that strange baseball than like the normal one. Before measurement, you don’t have a single hidden location waiting to be discovered; you have a structured set of possibilities. The very act of measuring—of putting out the glove—forces one of those possibilities to become actual.
Weird, right?
And that is where the reputation of “weirdness” comes from. But it’s crucial to say that quantum physics does not mean reality is arbitrary. It does not mean we create the world with our thoughts. It just means that, at the most fundamental level, reality is structured in ways that do not fit neatly into the categories we developed from everyday experience. The strangeness is not chaos. It is, however, a sign that our intuitions are limited.
This becomes especially important when people start talking about time. In everyday thinking (and in most bad time travel stories), time is treated like a simple sequence of moments, one after another, like beads on a string. Physics doesn’t treat it that way. In relativity, time is bound up with space. It is part of a four-dimensional structure, and your experience of “now” is not universal. Two observers moving differently can disagree about what events are simultaneous. Time itself can pass at different rates depending on motion and gravity. Already, that should make us cautious about treating time as something easily navigated or reversed.
Quantum physics complicates the picture further, though not in the way pop culture usually suggests. At the quantum level, systems can exist in superpositions (multiple possible states at once) until they are measured. That has led some physicists to propose interpretations in which every possible outcome of an event actually occurs. This is where the idea of the multiverse gains traction, particularly in the work associated with Hugh Everett and the “Many-Worlds Interpretation.”
Here is where clarity matters. The “multiverse” is not a single, settled scientific conclusion. It is one way of interpreting the mathematics of quantum theory. Other interpretations exist. None of them have been directly observed. What has happened in popular culture is that a speculative framework has been turned into a narrative device. Suddenly, people talk as if there are infinite versions of themselves making different choices in different timelines, as if reality branches at every decision point and all possibilities are equally real.
The “multiverse” is not a single, settled scientific conclusion… What has happened in popular culture is that a speculative framework has been turned into a narrative device.
But that is not something physics has demonstrated. It is a philosophical extrapolation, and often a sloppy one. It may be a useful way for physicists to think through certain equations, but it does not give us license to imagine reality as a kind of cosmic “choose your own adventure” book where nothing ultimately matters because everything happens somewhere.
A similar problem shows up with the language of dimensions, but here it’s worth slowing down, because this is one place where careful thinking might actually help us think about Scripture more clearly rather than less.
In science fiction, a “higher dimension” is usually treated like another place you can go, like stepping through a door into a different world. In physics, however, the term is much more precise. A dimension is simply a direction or degree of freedom. We live in three dimensions of space and one of time. Some theories suggest there may be additional dimensions, but these are not alternate realms you could travel to; they are typically conceived as extremely small, tightly folded aspects of reality itself.
That distinction matters, but once you have it, it opens up something more interesting. A helpful way to think about dimensions is not as different “places,” but as different levels of access to the same reality. A two-dimensional creature, confined to a flat surface, would experience a three-dimensional object very strangely. If a sphere passed through its world, the creature wouldn’t see a sphere. It would see a point appear, expand into a circle, then shrink and disappear. The object isn’t changing, but its intersection with that lower-dimensional world is.
That gives us a way of speaking—carefully, metaphorically—about how the Bible describes God’s interaction with creation. Scripture does not present God as one more being inside the universe, moving around within space and time like we do. He is the Creator of that entire structure. But at certain moments, that reality “intersects” ours in ways that are localized, visible, and tangible.
The incarnation is, of course, the clearest example. In Jesus Christ, the eternal Son does not simply appear within the world as a projection or symbol. He truly takes on human nature, fully present within the constraints of space, time, and physical existence. If you want a loose analogy, it is not that God “moves down” from a higher place into a lower one, but that divine reality enters into the created order in a way that can be seen, touched, and known without ceasing to be what it eternally is.
The ascension then pushes in the other direction. Christ is not described as disappearing into non-existence or traveling to a distant location somewhere within the universe (which, incidentally, is what I was taught when growing up). He is taken up, removed from ordinary visibility, yet still bodily real (Lk. 24:50–53; Ac. 1:6–11). The language strains, because it is describing a shift that is not merely spatial. It is closer to saying that the “mode” of His presence changes, that He is no longer accessible within the same dimensional “slice” of reality we ordinarily inhabit. And, by the way, if that word “mode” makes you nervous, relax. This isn’t Modalism in disguise. We’re talking about a change in how Christ is present to us, not a change in who God is.
The goal is not to import physics into theology as if one explains the other. It is to use clear thinking about the structure of reality to prevent confusion.
This idea becomes even more striking when you get to the Bible’s cosmic imagery. The new heavens and new earth are not described as an escape from creation, but as its renewal. And the New Jerusalem in Revelation is nothing humanity ascends to; it is something that comes down (Rv. 21:2). The movement is toward union, not departure. If you wanted a conceptual handle for that, you might think in terms of what could be called (imperfectly, sure) a kind of dimensional convergence or “bleed,” where what is presently beyond ordinary perception becomes fully present within it. It’s less a collapse of reality than it is a fuller expression of it.
Now, that language has limits, and it can be pushed too far. But thinking in terms of dimensions can help us avoid flattening biblical language into something overly simplistic. It gives us a way to affirm both God’s transcendence and His real, historical, embodied interaction with the world. And that is the key point. The goal is not to import physics into theology as if one explains the other. It is to use clear thinking about the structure of reality to prevent confusion. When Scripture speaks of Christ being “taken up,” it is not speaking nonsense or myth. It is describing, in the language available to us, a reality that is not exhausted by the dimensions we directly perceive.
There is also a more immediate reason for engagement, and it has to do with how these ideas are being used in everyday discourse. Quantum language has been borrowed and repurposed in ways that sound scientific but are not. Take the common claim that “observation creates reality.” That phrase gets lifted straight out of discussions of quantum measurement and then expanded far beyond what it means. In physics, “observation” refers to a very specific kind of interaction in which an instrument or system interacts with a particle in a way that yields a measurable result. It does not mean human consciousness magically brings things into existence. But in popular usage, that’s exactly how it gets framed. You’ll hear versions of this floating in self-help spaces: if you just “focus your thoughts” correctly, if you “observe” your desired outcome with enough clarity, you can bring it into reality. That is not quantum physics. It is a metaphysical claim wearing scientific vocabulary as a costume.
Part of the appeal of [the multiverse] metaphor in everyday conversation is that it functions as a kind of anaesthetic for regret.
Or consider the way “multiple possibilities” gets turned into “all possibilities are real.” In quantum theory, before measurement, a system can be described as existing in a range of possible states. That’s a technical claim about how to model very small systems. But in everyday discourse, that gets inflated into something like: every decision you could make is actually made somewhere, in some other version of reality. You see this constantly in discussions of alternate timelines, in movies, and even in casual conversation. “There’s a version of me out there that made the other choice.”
It sounds sophisticated because it borrows ideas associated with the multiverse, but it also is indicative of how people think about responsibility. If every possible version of you exists, then your actual decisions begin to feel less weighty, which is a philosophical leap built on a misunderstanding. Part of the appeal of this metaphor in everyday conversation is that it functions as a kind of anaesthetic for regret. It reframes irreversible decisions, such as missed relationships or moral failures, as merely “local” outcomes, while a “truer” or “more fulfilled” version of you supposedly exists elsewhere. In doing so, it both softens disappointment and resolves the finality that gives real choices their weight, allowing a person to imagine that nothing has truly been forfeited.
The same thing happens with the word “energy.” In physics, energy is a precisely defined quantity. It can be measured, transferred, and conserved. In popular spiritual language, though, “energy” becomes a vague force that can be directed by intention. People talk about “raising their vibration,” “aligning with the right energy,” or “attracting outcomes” through internal states. Sometimes this is explicitly tied back to quantum ideas, as if the behavior of subatomic particles somehow justifies the idea that your thoughts can reshape external reality in a direct, causal way. But there is no serious line from quantum mechanics to that kind of claim. It’s a category mistake to take a technical description of physical systems and turn it into a universal explanation for human experience.
All of this matters because it shapes how people think about the nature of reality itself. If “quantum” becomes shorthand for “truth is flexible,” then the distinction between what is objectively the case and what we feel or prefer begins to erode. That is not a scientific development. It is a cultural one.
Christians should be able to recognize that and say so. If anything, the field of quantum physics itself points in the opposite direction of those claims. It shows that reality has a layered and consistent structure, even when that structure is difficult to grasp. Equations work and predictions hold. The technology built on quantum principles, everything from semiconductors to MRI machines, functions reliably. The strangeness is real, but it’s not arbitrary.
There are Christians who have taken this seriously without overreacting. J. Lanier Burns, whom I had the fortune of having a couple of classes with during my time at Dallas Theological Seminary, is a good example. John Polkinghorne is another. As both a theoretical physicist and a theologian, Polkinghorne approached quantum physics as a field that raises genuine philosophical questions and not as a tool for “proving” doctrine. What does it mean for causality if the fundamental level of reality is probabilistic? How should we think about the openness of the future? Where do we locate agency in a world that is not strictly deterministic? These are not questions that replace theology, but they interact with it in meaningful ways.
That kind of engagement is very different from the way quantum ideas are often handled in popular media. It is more careful and less interested in quick and tidy conclusions. It acknowledges that science describes the behavior of the physical world, while theology addresses the ultimate source and meaning of that world. The two are not competitors, nor are they interchangeable.
Quantum physics reminds us that reality is not as simple as we might like, and that our categories (useful as they are) do not exhaust what is there.
If you circle back to time travel stories, you can see how all of this plays out in a more familiar form. The stories that fail are usually the ones that treat reality as pliable without cost. They assume that time can be edited, that causes can be rearranged without consequence, that identity can remain stable even when the conditions that formed it are altered. The stories that work, on the other hand, tend to respect the structure of reality. They recognize that if you tamper with the past, you don’t just create a new outcome, but you risk unraveling the conditions that made the present (and therefore the future) possible in the first place. They build in limits, constraints, and consequences.
In a strange way, that instinct aligns more closely with a Christian understanding of the world than the looser, more chaotic visions often justified by a vague appeal to quantum mechanics. Scripture presents a reality that is ordered and meaningful, one in which actions have weight and history matters. It is not a system we can step outside of and rearrange at will. It is a creation that is sustained, moment by moment, by God Himself.
Quantum physics does not undermine that picture. If anything, it complicates our understanding of how that order is expressed at the smallest scales, but it does not remove the order itself. It reminds us, rather helpfully, that reality is not as simple as we might like, and that our categories (useful as they are) do not exhaust what is there.
That is a healthy place for a Christian to be. Not threatened, and not overly eager to claim scientific validation, but attentive. Willing to learn what the science actually says, willing to correct misunderstandings, and willing to let the complexity of the created world point beyond itself to the One who made it.
And maybe, along the way, willing to be a little more critical of any story, whether it’s a movie or a cultural idea, that tries to solve its problems by throwing around words it doesn’t really understand.
