Church's Thesis (Church's Conjecture)

Church's Thesis, also known as Church's Conjecture, is an idea in computer science proposing that any problem solvable by an effective method can be computed by a simple abstract machine called a Turing machine. In essence, it suggests that the concept of "computability" is fully captured by these machines, meaning no other method can solve a problem beyond what a Turing machine can do. It is not a formal theorem but a guiding hypothesis that shapes our understanding of what machines can compute.
