| rdfs:label | - List of discredited substances
|
| rdfs:comment | - This page is a list of substances or materials which are generally considered to be discredited. A substance may be discredited in one of three ways: 1.
* It was widely believed to exist at one time but is not any more. Such substances are often part of an obsolete scientific theory. 2.
* It was once believed to have drastically different properties from those accepted now. Significant properties it was widely claimed and believed to possess are no longer accepted. 3.
* It is currently believed to exist as part of a theory which has not met the theoretical and experimental requirements of mainstream science. In particular, such a theory must be predictive.
