Unraveling the Unanswered: The Mysteries Science Still Can't Crack

The entire known universe—every star, every galaxy, all of space and time itself—was once compressed into a region infinitesimally smaller than a single atom. And then, 13.8 billion years ago, it expanded. We call that the Big Bang. It’s the starting line for everything we can observe or measure. It's funny, it feels like another one of those fundamental questions. Last week, we were talking about why we sleep, something so basic to our existence, and how it remains this huge evolutionary puzzle. This feels like that, just on a cosmic scale. So I have to ask the simple, obvious question: what was there before?

And that is the most profound, and perhaps the most misleading, question in all of physics. Because our science, our entire framework for understanding reality, breaks down at that exact point. Our best theory of gravity, Einstein's General Relativity, works perfectly from a fraction of a second after the Big Bang onward. But at time zero? The equations just... give you infinities. They stop making sense. What do you mean they stop making sense? Like, the math is just broken? Exactly. It’s the universe giving us an error message. An infinity in a physics equation doesn't mean the quantity is actually infinite.

It means your theory has crashed. It’s a sign that the model—in this case, General Relativity—no longer applies. The conditions are too extreme. We call that point the singularity. Okay, so our current tools can't see past it. But surely people are trying to build new tools, right? I mean, I hear about things like string theory or multiverse ideas. Aren't those trying to peek behind that curtain? Oh, absolutely. And they are beautiful, elegant mathematical structures. They try to resolve that singularity by positing things like vibrating strings in higher dimensions, or our universe being one bubble in a larger cosmic foam.

But the catch is—and it's a big one—they are, for now, untestable. They are frameworks for what might have happened. So they’re philosophical, almost. They're mathematical. And that's not quite the same thing. But you're getting at the core problem. The difficulty isn't just a lack of data. It’s that the very language we're using might be wrong. How so? You keep asking what came "before." Think of it this way: what's north of the North Pole? Nothing. You can't go north of the North Pole. You're at the top. Any direction from there is south. Exactly. The question itself is based on a flawed premise.

Ohhh. Wow. Okay. I see where you're going. Many cosmologists believe the same logic applies to time. Time isn't a universal clock ticking in the background. It's a dimension, woven together with space into spacetime. And that fabric of spacetime is what came into existence at the Big Bang. So asking what happened "before" the Big Bang is, quite literally, like asking what's north of the North Pole. The concept of "before," of a timeline, may not even apply. So it's not a wall we just need to find a way to punch through. It’s more like... the edge of the map itself. And there's no paper beyond it to draw on.

That's a perfect way to put it. And for me, that's not a failure of science. It's the most awe-inspiring thing about it. It's a fundamental limit. It tells us that our human intuition about cause and effect, about beginnings and befores, might just be local bylaws that don't apply in the cosmic court. So we might just have to live with not knowing. We might. Or, we might have to invent a whole new kind of science, a new kind of language, to even ask the question correctly. And honestly? I find that possibility so much more compelling than any simple answer. There's a kind of beauty in an impenetrable mystery.

It reminds us that the universe is under no obligation to make sense to us.
