Comment on 'Ultradense protium p(0) and deuterium D(0) and their relation to ordinary Rydberg matter: a review' 2019 Physica Scripta 94, 075005

The article by Holmlid and Zeiner-Gundersen (2019, Physica Scripta, vol. 94, 075005) contains a number of claims that explicitly or implicitly contradict fundamental knowledge of modern science. Some can only be true if long held conservation laws are broken. One such is baryon number conservation. A second fatal mistake is the treatment of the structure of molecules that disregard fundamental quantum mechanical aspects, such as the concept of kinetic energy operators and the Heisenberg indeterminacy relations.
