@j_bertolotti @Quasilocal I think the question is what „have a solution“ means. If the question is „does -1 have a square root“ this leaves open in which context. In the real numbers, it is true and will always be true that -1 does not have a square root.

@leop___ @j_bertolotti @Quasilocal But then they invented/created/discovered complex numbers, an extension of real numbers and there you have a square root of -1. But the strict mathematical proofs are independent of time.
