Our answer is YES --> Imaginary numbers are denied in quantum mechanics and Erwin Schrödinger said it first, in 1926.
We understand that numbers find a natural origin in set theory but common set theory does not explain physics and does not explain reality.
However, a special set people hint at could exist, that features phases with phase transitions. Could this represent gravity, electromagnetism, the laser, etc.?
We are proposing the set Q* [see below], providing a solution to these physical questions in a natural setting with numbers, using the properties of Clifford multivectors. Critically, one can calculate the ratio of elements, which Gibbs vector calculus cannot do.
Further, and to answer this question, many proofs exist that rational numbers can be counted by natural numbers. The new set Q* satisfies this, opening new possibilities in the sets N and Z.
This is based on set theory, and is not decidable by voting. Contrary opinions are mistaken.

Unless we want irreproducibility, in Physics and Mathematics, we have to accept first that random variables do not exist, and second find ways to get probability and imaginary numbers (aka, non-numbers) out of quantum mechanics.
