Definition:Hypothesis

Definition
A hypothesis is a statement that is made whose truth value has not been established, but which is believed to be true.

The underlying idea is that its truth or falsehood is about to be investigated.

A hypothesis is considered by some branches of philosophy as being synonymous with the words wild guess.

Possibly the most famous still-unproved hypothesis is the Riemann Hypothesis.
