Abstract
Introduction IN a fascinating article which appeared in Nature of February 6, under the title “Stellar Evolution and the Expanding Universe, Mr. F. Hoyle has brought forward convincing arguments for the permanent creation of matter in space. Many physicists will find it difficult to accept this hypothesis. For if there is any law ‘which has withstood all changes and revelutions in physics, it is the law of conservation of energy, which according to Einstein's formula E = mc2 is equivalent to the conservation of mass. The same strange conclusion has, during recent years, been formulated by Prof. Pascual Jordan, but with an important modification, whereby the conservation law is not violated. This is achieved by taking account of the loss of gravitational energy connected with the creation of particles. As Jordan's papers do not seem to be known to many English-speaking physicists, I have asked him to write a short report of his work, and the following article is a translation of his article made by my collaborator, Dr. H. S. Green.
