>>11047149>What if you extend the complex numbers by adding a "hallucinatory number" h, where h is the solution to ?You could but you'd have to redefine norm in a way that allows for it to be negative but it's more useful and coincides with its current definition. And it would still make no sense talking about imaginary lengths, because lengths are real numbers greater than or equal to zero and imaginary numbers are none of those.
