The Edge We Photographed

Out in space, far away, there are some of the strangest places in the whole universe. They're called black holes, and here's what makes them so amazing: they pull on things so hard that nothing can get away from them — not even light!

Think about that. Light is the fastest thing there is, zooming across the whole universe. But a black hole pulls so strongly that if light gets too close, even it can't escape and fly back out. That's why a black hole looks like a dark circle — all the light that goes in stays in. They're not holes in the ground; they're places in space where everything is pulled toward the middle, super, super strongly.

Black holes are some of the most powerful things God ever made, way out in the deep parts of space where no person could ever go. And yet the Bible says God "hangs the earth on nothing" — He set the whole universe in place, the stars and the black holes and our little Earth, and He holds it all. Nothing in the whole universe is too big or too strange for God.

The God who made the most powerful places in the universe, far beyond where anyone can go, is the same God who is right here with you, close enough to hold your hand. Nothing is too big for Him — and you are never too small for Him to love.

How does anything get that heavy? A black hole forms when a huge amount of matter gets crushed into an incredibly small space — for example, when a giant star runs out of fuel and collapses under its own weight. The more you squeeze mass together, the stronger its gravity gets right near it. Squeeze enough into a small enough space, and the gravity at the surface becomes so strong that the escape speed — the speed you'd need to fly away — becomes faster than light. And since nothing can go faster than light, nothing can leave.

Around every black hole there's an invisible boundary called the event horizon. It's not a solid surface; it's a line in space that marks the point of no return. Outside it, you could still (with enough power) escape. Cross it, and you never can — everything inside is pulled inevitably toward the center. We can't see the black hole itself, but we can see the effects around it: gas swirling in spirals as it falls, heating up and glowing brilliantly, like water circling a drain, just before it disappears past the edge forever.

Psalm 147 says God's "understanding is beyond comprehension." A black hole is one of those things that stretches your mind until it almost can't follow — a place where the normal rules bend, where even light is trapped, where our everyday intuitions break down. And it's just one of the things God made and understands completely. What overwhelms our minds is something He holds with ease.

When you run into things too big to wrap your head around — in the universe, or in your own life — it's a comfort that there's Someone whose understanding has no limit. You don't have to comprehend everything. You can rest in a God who already does.

For most of a century, black holes were math. Einstein's theory predicted them; the equations demanded them; astronomers found powerful indirect evidence. But no one had ever seen one, because the whole point of a black hole is that it gives off no light. Photographing the unphotographable seemed impossible.

Then, in April 2019, scientists released the first-ever image of a black hole — the supermassive one at the heart of galaxy M87, 55 million light-years away. To do it, they faced a problem: a single telescope big enough would have to be the size of the Earth. So they essentially built one. They linked radio telescopes scattered across the entire planet — from Hawaii to Spain to the South Pole — and combined their data so precisely that, working together, they acted as one Earth-sized telescope. The image shows exactly what relativity predicted: a ring of light bent around a central darkness, the black hole's "shadow." Then in 2022 they did it again, photographing the black hole at the center of our own Milky Way. We turned the planet itself into an eye and looked at the edge of the abyss — and the math was right.

Here's what's striking. We extended our vision to the literal limit — a telescope as wide as the world — and what we found at the edge of our reach was a boundary we cannot cross or see beyond. The event horizon is, by its nature, a place our knowing stops. Isaiah's words fit the moment with eerie precision: "as the heavens are higher than the earth, so my ways are higher than your ways and my thoughts higher than your thoughts." We strain upward as far as we possibly can, and discover that reality keeps a region permanently higher and deeper than our reach. That's not a failure of science. It's a feature of a universe made by a God whose thoughts genuinely exceed ours.

Your generation has astonishing reach — you can look up almost any fact, see almost anywhere, know almost anything in seconds. That can quietly convince you that everything is, in principle, within your grasp; that mystery is just unsearched information. The black hole's horizon is a healthy correction. We built an eye the size of a planet and found a wall we can't see past. There will always be a "higher than your thoughts" — and learning to stand humbly at that edge, instead of pretending it isn't there, is the beginning of wisdom and of worship.

The image of the black hole was a triumph, and triumphs in science have a way of feeling like closure — we predicted it, we photographed it, the theory held. But a black hole is precisely the object where our two deepest theories of reality stop agreeing, and the disagreement is not a small one. The horizon we photographed is the doorway to genuinely unfinished physics.

Two unsolved problems sit at the heart of it. The first: general relativity, our theory of gravity, predicts that at the very center of a black hole lies a singularity — a point of infinite density where the equations themselves break down and stop giving sensible answers. Infinity in a physics equation is a sign that the theory has reached its limit, not that the universe actually contains an infinity. To describe the center truly, we would need a theory of quantum gravity — a marriage of relativity and quantum mechanics — that we do not yet have, despite a century of effort. The second is sharper still: the black hole information paradox. Stephen Hawking showed that black holes slowly evaporate, leaking radiation over unimaginable timespans. But quantum mechanics insists information can never be truly destroyed — and it has never been fully resolved how the information about everything that fell in is preserved when the black hole finally disappears. It is one of the most important open problems in theoretical physics, with brilliant people still actively at work on it right now. We photographed the edge, and the edge turned out to be the boundary of what our best science can yet describe. We have a picture of the object, and no equation that survives its center.

Scripture has its own unapproachable center, and Paul names it: God "lives in light so brilliant that no human can approach him. No human eye has ever seen him, nor ever will." Hold the two images together. A black hole is an unapproachable darkness — cross its horizon and you are lost, its center a place our knowing cannot enter. God is an unapproachable light — too bright, too holy, too much for any creature to look upon and live. Both are boundaries we cannot cross; but they could not be more opposite in nature. One is a place where everything that enters is consumed and lost forever. The other is the source of all life, who can never die, whose unapproachability is the unapproachability of too much glory, not too much ruin. We were made for one of those centers, not the other — and the whole of the gospel is that the unapproachable Light came near, on His own initiative, in a form we could finally bear to look at: a face, a voice, a man.

There is a fear that can stalk a thinking adult faith: that at the center of everything is not a Person but a void — that if you push past the comforts and the metaphors to the true heart of reality, you'll find only an indifferent darkness, a singularity where meaning breaks down. The black hole makes that fear vivid. But Paul insists the actual center is the reverse: not an unapproachable dark that destroys, but an unapproachable Light that lives and gives life — and One who did not stay safely beyond the horizon of our reach. "No human eye has ever seen him" — and then, John writes, the Word became flesh, and we have seen his glory. The center of reality is not a singularity that swallows you. It is a brilliance that came looking for you, dimmed itself to a size you could approach, and means to bring you home into the light.
