Fluctuations in the Primordial Fireball

Nature volume 215, pages 1155–1156 (1967)Cite this article

Abstract

ONE of the overwhelming difficulties of realistic cosmological models is the inadequacy of Einstein's gravitational theory to explain the process of galaxy formation1–6. A means of evading this problem has been to postulate an initial spectrum of primordial fluctuations7. The interpretation of the recently discovered 3° K microwave background as being of cosmological origin8,9 implies that fluctuations may not condense out of the expanding universe until an epoch when matter and radiation have decoupled4, at a temperature TD of the order of 4,000° K. The question may then be posed: would fluctuations in the primordial fireball survive to an epoch when galaxy formation is possible ?
