Sometimes a conjecture is called a hypothesis when it is used frequently and repeatedly as an assumption in proofs of other results. For example, the Riemann hypothesis is a conjecture from number theory that (amongst other things) makes predictions about the distribution of prime numbers.
A contradiction is two propositions used in combination where one makes the other impossible. It is something that is A and non-A at the same time. A contradiction, therefore, cannot exist in reality, since existence exists (whereas a contradiction could not possibly exist). In the cognitive process, reaching a contradiction as a conclusion or evaluation of reality is proof of an error in one's thinking. A square circle is a contradiction in terms.
