The thing is about how you define solvable church's thesis states that if you were to use the informal notion of solvable, then it is exactly the same as the notion of solvable by a turing machine, and the proof then follows. We prove that if our calculating capability is limited to that of a universal turing machine with a finite tape, then church's thesis is true. Alan turing’s mathematical logic: this church-turing proof is a negative solution that would end this line of research as church-turing thesis had almost done.

Church's thesis asserts that the only numeric functions that can be calculated by effective means are the recursive ones, which are the same, extensionally, as the turing-computable numeric functions.
