>>14093562Math is made up, it's a tool for abstracting a problem. Nothing in math really "exists", numbers aren't a thing in the real world, they're an abstract concept, an idea. The only metric of validity for any given mathematical construct is how useful it is to solve real-world problems. Imaginary numbers have proven useful in many areas, like with Fourier transforms, which again has found applications in thermodynamics and quantum mechanics.
