There are many statements about scientific ideas that are false but are perceived to be true by many people. Scientific hypotheses and theories are subject to revision on the basis of observations, improvements in technology, and continued scrutiny. Inevitably certain "truths" are reconsidered. This is how honest science works. Brief explanations follow each of the FALSE statements and web site links are provided for reinforcement and/or substantiation. For the few items in which there is controversy or clear disagreement, the scientific view is presented.
