At first glance, they seem like abstract tools with no physical meaning. But when you look deeper, they show up everywhere: in quantum mechanics, wave behavior, electrical engineering, and even in how we describe the evolution of the universe itself. We start by unpacking what imaginary numbers really are—not fake, but part of a larger number system called the complex plane. Then we look at how physicists use them in equations like the Schrödinger equation, where they aren’t just convenient shortcuts—they’re essential. Without imaginary numbers, the math breaks, and the theory stops working. But why? One possibility is that imaginary numbers are just a powerful mathematical language—like coordinate systems or variables—that help us describe reality without being reality themselves. Physics is full of these kinds of tools. But there’s another, more intriguing possibility. In some areas of physics, like quantum theory and relativity, imaginary numbers don’t just simplify equations—they reveal deeper structure. Concepts like imaginary time, used in models of the early universe, suggest that what we perceive as the flow of time might be part of a larger geometric framework. In these cases, imaginary numbers may be hinting at aspects of reality that don’t look like space or time as we experience them, but are still fundamentally real. So do imaginary numbers represent a hidden dimension? A deeper layer of physics? Or are they just the most efficient way we’ve found to describe patterns we don’t yet fully understand? This video doesn’t claim to have the final answer—but it does show why this question is worth asking. Because sometimes, the tools we invent to describe reality end up revealing more about it than we ever expected.

Hidden dimensions?

Buried deep inside some of the most successful equations in physics is something that seems almost absurd at first glance. Imaginary numbers. Numbers built from the square root of a negative number. Something that on the surface shouldn't even exist. And yet imaginary numbers appear everywhere in physics. Wave mechanics, electricity, magnetism, relativity, quantum theory, and even some models of cosmology. In fact, some of the deepest equations in physics become almost impossible to write in their most elegant form without them. So, what's going on here? Are imaginary numbers just a mathematical trick? Like a bookkeeping device that helps us solve equations, but means nothing physically? Or could they point to something deeper? A hidden layer of reality that our everyday senses don't have access to. Could they be pointing to new physics? Hidden dimensions, maybe? Or a broader structure beneath the universe that we don't observe? Stay tuned because the answer to those questions is coming up right now. —

What are imaginary numbers?

— The name imaginary causes a lot of confusion. An imaginary number is based on the symbol I, defined as the square root of -1. At first, that sounds like nonsense because, as you know, if you square any ordinary positive number, you get a positive result. — And if you square a negative number, you still get a positive result. So, there seems to be no real number whose square should be a negative one. That's why mathematicians historically called it imaginary. But that name is misleading because imaginary numbers are not fake. They are not made up in the sense of being arbitrary. They're part of a larger system called complex numbers. And complex numbers are as mathematically consistent as ordinary numbers. So, a better way to think of them is that imaginary numbers are not any less real than real numbers. They just extend the number system into a new direction. If ordinary real numbers lie along a horizontal line, then imaginary vertical line. — And together, they form a plane, that is, the complex plane. So, instead of having just one numerical direction, positive and negative, we now have two independent directions, the real direction and the imaginary direction. This is not much different from how geometry works. If you lived on a one-dimensional line, you might think that left and right are the only possible directions. Then someone introduces the concept of up and down. That new direction might seem mysterious at first, — but it wouldn't be imaginary in the everyday sense. It would just be a dimension you weren't accounting for before. So, that's the first important point. Imaginary numbers are not nonsense. They are a natural extension of the idea of numbers. And once you allow that extension, something remarkable happens. The

How imaginary numbers represent cycles and waves

mathematics of oscillations, rotations, and waves becomes much simpler. And physics turns out to love waves, which, as I'm sure you know if you watched any of my videos in quantum mechanics. So, there's a reason physics loves imaginary numbers. One of the most beautiful equations in mathematics is Euler's formula. This equation connects exponentials, that is, trigonometry, and imaginary numbers in a way that seems almost magical. But physically, what it really is describing is rotation. If you multiply by a complex exponential, you're rotating in the complex plane. And that matters because waves can be represented as rotating quantities. For example, a sine wave and a cosine wave are really two aspects of the same rotational motion. If you imagine the tip of a rotating arrow moving in a circle, its shadow on one axis gives you a cosine wave, and its shadow on the perpendicular axis gives you a sine wave. Complex numbers package both of these together into one elegant object. That is why engineers use them in circuits, and that's why physicists use them — for oscillations. So, in many cases, imaginary numbers are not necessarily telling us — there's an imaginary physical substance floating around in nature. They're giving us a compact language for describing systems that involve cycles, phases, and rotations. And phase is incredibly important in physics. Two waves can have the same amplitude but different phases. When they combine, they can reinforce each other or cancel each other out. This is true for sound, for light, and most dramatically for quantum systems. So, already we can say something important. Imaginary numbers are not just a random trick. They naturally encode phase and rotation, which are generally physical features of the world. But again, that does not mean imaginary numbers themselves are physically real in the same sense that a rock or an electron is real. — But it does mean they're tied to real structure. And nowhere is that more relevant than in quantum mechanics, where imaginary numbers play a strange but very real role. —

— And this leads to something interesting. The idea of using something that seems abstract or even counterintuitive to solve real-world problems doesn't just show up in physics. It shows up in technology, too. And for a long time charging devices had a built-in trade-off. If you wanted more power, you needed something bigger. And more power also meant heat, which reduces efficiency. So you couldn't have everything at once, but Anker, our sponsor today, has pushed past that limitation. Their latest system, GaN Prime 2. 0, is built around what feels like a paradox. Smaller size, but higher power. Lower temperature, but greater efficiency. Here's the real challenge. As power increases, heat builds up rapidly. And in a compact device, that heat has nowhere to go. That leads to something called power derating, where the charger has to reduce its output to avoid overheating. So even if a charger is rated for high power, it can't sustain it. And the problem gets worse because of thermal coupling. That is, heat from one component spreads to nearby components, making the whole system less stable and inefficient. What Anker has done is treat this as a system problem, not just a materials problem. — First, they use gallium nitride, or GaN, which allows higher efficiency and smaller components. But GaN alone isn't enough. They redesigned the internal power architecture using what's called an M buck multi-level topology without scaling everything up in size, — achieving a power density of 1. 3 W per cubic centimeter, the highest in its class. Think of it like this. The inductor inside a charger acts like an energy reservoir. And normally, higher power means you need a larger one. But this design allows them to handle high power without scaling everything up in size. Then comes heat management, which is where most designs fail. Anker uses three key innovations. First, mold release potting, which fills every gap inside the charger, turning the entire device into a uniform heat conducting structure. Instead of heat getting it trapped in hot spots, it spreads evenly like ripples in water. Second, L-shaped graphene layers, which rapidly move heat away from the hottest components — to cooler areas. And third, Active Shield 4. 0, which performs millions of temperature checks per day to dynamically regulate performance in real time. The result is a system that sustains high power output without overheating, even when charging multiple devices at once. So, instead of choosing between size, power, and safety, you get all three. And on the software side, Power IQ 5. 0 intelligently distributes power in real time. So, a single Anker Prime 160 W charger, like this, can match the combined charging performance of those separate original chargers. That's 160 W of input delivering 210 W of effective output. And that's a great example of how something that looks like a paradox — can be overcome by rethinking the problem at a deeper level.

How imaginary numbers are the heart of quantum mechanics

innovations. In the strange world of quantum mechanics, imaginary numbers are also doing something that seems paradoxical. As you know, quantum mechanics is arguably the most successful scientific theory ever developed. It predicts the behavior of atoms, electrons, lasers, semiconductors, chemical bonds, and a huge portion of modern technology with incredible precision. And right at the heart of quantum mechanics sits this equation. This is the Schrödinger equation, which describes how a quantum particle changes over time. It contains a wave function, psi. It describes where quantum particle might be found if you try to measure it. Notice that I is not just there as a convenience. It's built into the equation itself. Now, this is significant because the wave function is generally a complex valued function. It means it contains both real and imaginary components. Now, here's the subtle part. We don't directly measure the wave function itself. What we measure are things like probabilities. And the probabilities come from the absolute square of the wave function, which turns the final measurable result into an ordinary real number. So, one common view is this. The imaginary parts are just intermediate mathematical ingredients. They help us calculate real observables, but they're not themselves directly observable. That is the conservative mainstream interpretation, and it's perfectly respectable. But there is something a little unsatisfying about stopping there. Just because the imaginary part may not be directly observed, it doesn't mean

Not observed so is it not real?

it's irrelevant. Without it, the theory wouldn't work. The phase relationships encoded in the complex wave function determine interference effects. And interference is one of the most real features of quantum mechanics. When an electron goes through a double slit and produces an interference pattern, the complex nature of the wave function is not optional. It is explaining how reality works. So, this raises a philosophical question. If something is not directly visible, but it has measurable consequences, can it be unreal? We don't see electron fields directly, either. We infer them from their effects. We don't see space-time curvature directly. We infer it from how matter moves. So, perhaps the imaginary component of the wave function is not directly observable in isolation, but it still reflects part of the underlying nature of reality. Now, I have to tell you that this is not established fact, but it is a serious question, and it leads to a deeper possibility. Could reality itself be complex?

Could reality itself be complex?

Suppose the universe is not fundamentally described by real numbers alone. Suppose instead that the deeper mathematical fabric of reality is complex. What would that mean? It would mean that what we call physical reality, the part we measure, might be only the real projection — of a richer underlying structure. Think of a three-dimensional object casting a two-dimensional shadow. The shadow is real. It carries information, but it does not capture the full object. A sphere and a cylinder might cast similar shadows from certain angles. From the shadow alone, you don't necessarily know the true shape of the higher-dimensional object that produced it. In the same way, the real quantities we observe may be only a partial slice of a more complete complex structure. So, one philosophical interpretation is that the imaginary component is not fake, it's hidden. Not hidden in the mystical sense, hidden in the same sense that the full three-dimensional shape of an object is hidden if you only look at a shadow. If that were true, then imaginary numbers would not merely be computational tools, they would encode degrees of freedom that are real but not directly accessible. Again, this is an interpretation, not an established conclusion. But it's one reason I find this topic so fascinating because the mathematics seems to be whispering that there's more structure there than meets the eye. Now, let's go one step further. There is

Imaginary TIME?

a concept in theoretical physics called imaginary time. This comes up in a mathematical technique called Wick rotation, where physicists replace ordinary time with imaginary time. Now, why would anyone do something like that? Because certain equations become easier to handle when time is treated as imaginary rather than real. Problems that are difficult in ordinary space-time can sometimes be transformed into simpler geometric problems. This technique is extremely useful in quantum field theory and statistical mechanics. Now, most of the time imaginary time is treated as exactly that. A mathematical transformation, a tool, a way of turning one kind of problem into another. But some physicists, including Stephen Hawking in some of his popular explanations, entertain the idea — that imaginary time might not just be a trick. It might reflect something profound about the structure of the universe. In certain models using imaginary time smooths out what would otherwise look like a singular beginning of the universe. Instead of a sharp boundary where time begins, the geometry becomes more like the surface of Earth, finite but without an edge. To be clear, this is not standard observationally confirmed physics. It's an interpretation of certain models. But philosophically, it's very intriguing because it hints that our ordinary notion of time flowing from past to future in only one direction may not be the deepest possible description. Maybe what we experience as time is one aspect of a larger mathematical structure, part of which naturally involves imaginary directions. Now, this doesn't prove that imaginary time is definitely real, but it does show that the distinction between mere mathematics and physical structure can become blurry at the edge of physics.

Could imaginary numbers reveal hidden dimension?

physics. Now, we come to the most speculative part. Could imaginary numbers represent actual dimensions of reality. Usually when physicists talk about dimensions, they mean independent directions — in which things can vary. Space has three familiar spatial dimensions. — Time adds another dimension, though it behaves differently than spatial dimensions. So, could there be dimensions associated with complex or imaginary directions? Mathematically, yes. You can formulate theories that use — complexified spaces. In fact, physicists often do this in advanced calculations. But, whether those complex directions are physically real is a different matter. There is no accepted experimental evidence that the universe contains literally imaginary dimensions. But, still the idea is not completely unreasonable as a philosophical proposal. If a hidden dimension influenced what we observe without being directly observable itself, it might look a lot like the role imaginary quantities already play in our theories. And if one day we discovered a deeper theory in which the complex structure of quantum mechanics emerges from a larger geometric framework, then imaginary numbers might turn out to correspond to something more physically substantial than we currently think. That could count as new physics. It might not mean extra dimensions in the science fiction sense where you can step sideways into another world. — It might instead mean that reality has additional levels or structure that don't look spatial at all, but are still objectively part of the universe. In other words, imaginary numbers might not represent another place, they might represent another aspect of what existence is allowed to be. Now, this is speculative, but it is a disciplined kind of speculation. The kind that begins from real mathematics and real physics rather than fantasy. Now, as scientists, we also have to be

The skeptic point of view

careful and explain the skeptical view because it's easy to land on the planet crackpot. A lot of popular blogs and videos make the leap from imaginary numbers appear in physics to therefore imaginary worlds are real. — That's not justified. Mainstream physics is much more restrained. It says three things. Complex numbers are part of mathematical formalism. Only measurable quantities are real. The fact that a mathematical object appears in our equations does not automatically mean it exists as a physical entity. And that is an important caution. After all, mathematics is full of structures that are useful without necessarily corresponding one-to-one with physical objects. For example, coordinate systems, gauge choices, variables. All of these can be indispensable without being the makeup of the universe. So, the burden of proof is high. If you want to say imaginary numbers are physically real, we would need more than elegance. We would need a theory that makes distinct predictions or a deeper explanatory framework that reveals that complex numbers are unavoidable features of ontology, not just mathematical formulations. Right now, we don't have that. So, the objective conclusion is this. There's no established evidence that imaginary

The objective conclusion

numbers are directly physical things. But, there's also a more subtle conclusion. Their persistent and indispensable role in our best theories may be telling us something deep about how reality is organized. And that is a very different claim. It's a much more defensible claim. There is a long history of science of mathematical entities first being featured as abstractions, then later being recognized as central to physical reality. Negative numbers once seemed suspicious, then they became natural ways of describing direction, charge, and debt. Non-Euclidean geometry was once a mathematical curiosity, then Einstein used it to describe gravity. Complex numbers were once regarded as formal tricks, then quantum mechanics placed them at the center of the microscopic world. So, we should be humble. The universe has repeatedly shown us that reality is under no obligation to match human intuition. What seems abstract, artificial, or impossible from the standpoint of everyday experience may turn out to be exactly the language that nature prefers. Now, this doesn't mean that every mathematical structure is real, but it does mean we should not dismiss something merely because it sounds strange. Reality may not be built only from things we can make sense of. It may be built from relationships, symmetries, and structures that are more abstract than common sense can handle. The chair you sit on, the screen you're looking at, the atoms in your body, all of them ultimately obey equations in which imaginary numbers — quietly do some real essential work. So, perhaps imaginary is just a historical accident. — Perhaps these numbers are not signs of unreality. Perhaps they are signs that reality is richer than the human brain evolved to visualize. Hope you learned something. I'll see you in the next video, my friend.
