A scientific fact is a statement about the natural world that competent observers (who have made observations or performed experiments) all agree on. A hypothesis is an educated guess, an attempt to explain an observation or the results of an experiment, but one that has not yet been repeatedly tested. A law is a hypothesis that has been tested repeatedly without being contradicted by experimental findings or observations. A theory is a coherent set of laws relating to some aspects of the natural world.
