NEW EVIDENCE FOUND OF EXPANDING UNIVERSE — The universe is expanding, then collapsing again after a long time, evidence from photographs taken with the 200-inch telescope atop Mt. Palomar indicate. Dr. William A. Baum of Mt. Wilson and Palomar Observatories, Pasadena, Calif., said that present-day observations are not compatible with a steady-state universe in which matter is continuously being created. The observations were made on very distant galaxies belonging to clusters of galaxies, he told the Royal Astronomical Society meeting in London. The observations are based on the red-shift of the light from these galaxies.
