Cambridge University Press 0521019265 - A Different Approach to Cosmology: From a Static Universe through the Big Bang towards Reality F. Hoyle, G. Burbidge and J. V. Narlikar Frontmatter More information A DIFFERENT APPROACH TO COSMOLOGY This is a different kind of book about cosmology, a ®eld of major interest to professional astronomers, physicists, and the general public. All research in cosmology adopts one model of the universe, the hot big-bang model. But Fred Hoyle, Geoffrey Burbidge and Jayant Narlikar take a different approach. Starting with the beginnings of modern cosmology, they then conduct a wide ranging and deep review of the observations made from 1945 to the present day. Here they challenge many conventional interpretations. The latter part of the book presents the authors' own account of the present status of observations and how they should be explained. The controversial theme is that the dependency on the hot big-bang model has led to an unwarranted rejection of alternative cosmological models. Writing from the heart, with passion and punch, these three cosmologists make a powerful case for viewing the universe in a different light. Sir Fred Hoyle held the Plumian Chair of Astronomy at the University of Cambridge 1958±72. Geoffrey Burbidge is at the Center for Astrophysics and Space Sciences, University of California, San Diego. He has held positions at the California Institute of Technology, the University of Chicago, and Harvard University and was Director of the Kitt Peak National Observatory 1978±84.

Hoyle, G. Burbidge and J. V. Narlikar Frontmatter More information Preface This is a different kind of book about cosmology. In the past 10 or 15 years, there has been a great spate of textbooks, monographs and popular books on this subject. There is no question but that cosmology has developed into a major topicof study for astronomers, physicistsand laymen alike. The reasons for this are not hard to ®nd. We are all keenly interested in where we came from and where we are going, and cosmology, the study of the whole universe, is supposed to give us the answers to these basicquestions. In this sense it has much the same attraction for many as does religion. Both have been dominated in the past by a small number of facts and large mea- sures of belief. Some genuine progress in cosmology has come, however, mostly from advances in observational astronomy leading to new informa- tion being obtained at an increasing rate in the past 40 years. These advances have nearly all come from advances in technology at opti- cal wavelengths, and investigations of the universe at radio, infrared, and ultraviolet frequencies, and at X-ray and -ray energies. Naturally this has led to a huge increase in the number of scientists in the ®eld, and to much larger sums of money being required. This is inevitable, but it has a downside. For example, physicists with no background in astronomy have moved into cosmology in large numbers. However, without knowledge of what has gone before, there is always a lack of perspective, and this shows up very strongly when any attempt is made to consider alternative explanations of what are often considered to be well-established facts. Also, astrophysics and cosmology is now big science, which requires large sums of money to support it. The major sources of funds are National Government Agencies, such as the National Science Foundation and the National Aeronautics and Space Administration in the USA. The agencies providing the money then make a considerable impact on the way we do science. For example, if you are funded by NASA, you are vii © Cambridge University Press www.cambridge.org Cambridge University Press 0521019265 - A Different Approach to Cosmology: From a Static Universe through the Big Bang towards Reality F.

A fact of life which is well known to the professionals, but which has probably not yet been digested by the world at large, is that the effort and propaganda required to get a major instrument funded ± say the Hubble Space Telescope, or the Cosmic Background Explorer Satellite (COBE) ± requires that before the instruments can be built, extravagant claims must be made about what we shall ®nd. Not surprisingly, when these instruments eventually work, we get a succession of even stronger claims to the effect that what was expected has indeed been found. Some of the claims are amazing even to those who work in the ®eld, e.g. about the microwave background radiation and its ¯uctuations: `They have found the Holy Grail of Cosmology', Dr Michael Turner, University of Chicago. `Well, if you are a religious person, it's like seeing the face of God', Dr George Smoot, University of California, Berkeley. In an era when serious scientists can take such an approach, there is no room for the discovery of phenomena which are not already expected. Those few scientists who want to look for things that they may not be able to explain simply cannot get telescope time. The people who assign observing time on the telescopes using the so-called peer review system demand that you explain beforehand what you will ®nd. And those who do ®nd such phenomena by accident mostly can be relied on to be so conformist that they put them aside. And, of course, if you know little of the history of science, and particularly if you are a particle physicist, you are con®dent that there is nothing to learn from astronomy about fundamental physics.
