Abstract
THE RADIUS OF SPACEmdahs;The following cablegram (which has been somewhat expanded from its very concise telegraphic wording) was received from Dr. Ludwik Silberstein on April 10: “A star formula which is developed in the course of my monograph ‘ The Size of the Universe,’ now in course of publication at the Oxford University Press, when applied to 35 stars of type O yields for the radius of space the value 3-2 x 1011 astronomical units; when applied to 29 Cepheids, 3-0 x 1011, and when applied to the 246 more distant stars of Young and Harper's list, 3-4 x 1011 units. The latter computation was completed on April 7; its agreement with the two former ones definitely establishes that space is finite, and that its radius is thirty trillion miles (in the British use of the term), or about five million light-years.”
