A supposition; a proposition or principle which is supposed or taken for granted, in order to draw a conclusion or inference for proof of the point in question; something not proved, but assumed for the purpose of argument, or to account for a fact or an occurrence; as, the hypothesis that head winds detain an overdue steamer.
A tentative theory or supposition provisionally adopted to explain certain facts, and to guide in the investigation of others; hence, frequently called a working hypothesis.
There are two possible outcomes: if the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery. Enrico Fermi
The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic or molecular constitution of matter. C. V. Raman
The great tragedy of science - the slaying of a beautiful hypothesis by an ugly fact. Thomas Huxley
If the facts are contrary to any predictions, then the hypothesis is wrong no matter how appealing. David Douglass
God is not a hypothesis derived from logical assumptions, but an immediate insight, self-evident as light. He is not something to be sought in the darkness with the light of reason. He is the light. Abraham Joshua Heschel
