Arvin Ash | Do Imaginary Numbers Reveal a Hidden Layer of Reality?

What if one of the most “imaginary” ideas in math is actually pointing to something real about the universe?

In this video, we explore the surprising role of imaginary numbers, numbers involving √−1—in modern physics. 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.
