sciencefact

Sciencefact is a nontechnical term used in popular discourse to denote a claim that is supported by empirical evidence, reproducible observations, and broad consensus within the scientific community. It is not a formal designation used in peer-reviewed science, but rather a way to signal that a statement has been corroborated through the scientific method and is widely accepted as true within current knowledge.

The term is often contrasted with hypotheses, which are testable explanations awaiting verification, and with theories, which are well-substantiated frameworks that explain a wide range of phenomena. Sciencefact is thus meant to convey a level of reliability beyond a simple claim, without implying absolute certainty, since scientific understanding can evolve with new evidence.

Examples commonly associated with sciencefact include statements such as that water is composed of hydrogen and oxygen (H2O), that the Earth orbits the Sun, and that the speed of light in a vacuum is approximately 299,792 kilometers per second. These statements are supported by extensive empirical data and remain robust under current investigation, though scientific nuance and precision may be refined over time.

Caveats accompany the use of sciencefact: labeling something as a sciencefact can create an impression of finality and may obscure ongoing uncertainties or debates in frontier research. In science communication, the term should be paired with sources, caveats, and context to maintain accuracy and transparency.
