Scientists call it the working hypothesis and it is always tied to a certain area or problem (maybe except physics). Common folks tend to explain it by God's will.
Of course, the difference between the two is that scientific working hypotheses (including those in physics) are continuously tested and rejected when the experimental data makes their continuation untenable, while God's will is usually neither tested nor rejected by the faithful who more often than not tend to frown upon such investigative activities.
