A thought-provoking insight into the evolution of cosmology for undergraduate students and general readers, this book shows that the mystery of the origin of the universe is far from being solved. Cosmology has advanced over time through observational evidence as well as a lot of speculation. In this historical approach, the authors argue that the speculative element has become a dominant part of modern cosmology. They show how assumptions have been made and portrayed as confirmed facts. This unique book gives not only a critical assessment of the big bang theory, but presents a host of anomalous observations, and puts forward an alternative, controversial theory on the origin of the universe. A non-mathematical account, it contains analogies from everyday life so that readers can understand the concepts easily and follow the arguments presented.

Review
"Too few scientists take pains to what emphasize what we actually know and what's speculation, which is why this book is so refreshing. Mainstream cosmologists maintain that the standard picture is supported by interconnected observations and it is not time for a radical alternative like Narlikar and Burbidge's 'quasi-steady state theory'. But these are certainly interesting times, and they are perfectly expounded in this comprehensive book." Rated 5 out of 5 stars and named book of the month in January 2009 - Marcus Chown, BBC Sky at Night
"Highly Recommended. General readers, all undergraduates, graduate students, and professionals." - B.R. Parker, emeritus, Idaho State University
About the Author
Jayant V. Narlikar is Emeritus Professor at the Inter-University Centre for Astronomy and Astrophysics, Pune, India. Known for his work on cosmology, Narlikar served as President of the Cosmology Commission of the International Astronomical Union (1994-97). Other books by Professor Narlikar include An Introduction to Cosmology (now in its third edition, 2002) and Current Issues in Cosmology (with Jean-Claude Pecker, 2006), both with Cambridge University Press.
Geoffrey Burbidge is a Professor in the Department of Physics at the University of California, San Diego. He is best known for his work on stellar nucleosynthesis and quasi-stellar objects. Professor Burbidge has been the recipient of several awards, most recently the Gold Medal of the Royal Astronomical Society with Margaret Burbidge. He co-authored A Different Approach to Cosmology (with Jayant Narlikar and Fred Hoyle, Cambridge University Press, released in paperback in 2005).

Defending Steady-State
By Doctor Moss
Jayant Narlikar and Geoffrey Burbidge were both students and colleagues of Fred Hoyle, the most visible proponent of the "steady-state" cosmological model, an alternative to the commonly accepted "big bang" model. This book is intended to call attention to problems, both theoretical and observational, with the big bang model, problems which at the same time suggest something more like the steady-state model.
Not being an astronomer or a physicist, I'm not in a position to say whether they have a real case. They do cite a number of observations and discrepancies that seem better addressed by a revised steady-state model (the "quasi-steady-state cosmology"), as well as explanations within the bounds of their model for what have been taken as strong confirming evidence for the big bang model.
But I do think they come off as a bit . . . whiney. They think that the big bang model has won out by virtue of marketing rather than science. For example, in speaking of one aspect of the current big bang model, "inflation" in the very early universe, they say, ". . . the idea of inflation survived [early discrepancies with observations], largely because it was marketed superbly." They believe that agencies and boards that fund research or decide on how observing time at major observatories (including Hubble) is used are biased in such a way that major research is restricted to validations of the big bang model or ways of conforming it to previous evidence.
The steady-state model has one big problem. It requires continuous creation of matter, i.e., the overall mass of the universe has to be in constant increase (and it's not just conversion of energy to mass -- the whole thing has to be growing).
The authors raise a philosophical objection to the big bang, that there is a single moment, a single event that is like no other in the history of the universe. It happens only once, and scientists don't like things that happen only once -- such "singular" events are very hard to explain, especially when that event is the creation of everything.
The steady-state theory has the advantage of positing continuous rather than one-time creation. Creation happens over and over -- it's study-able, like good scientific events should be. If they are right, of course, that creation is going on now, and it should in principle be detectible. Their theory claims that such creation can only happen in regions of very high matter density, especially the centers of galaxies. They cite observations of active galactic nuclei as potentially confirming evidence. But they have no solid account of how the creation of new matter actually happens in such places.
No doubt, Narlikar and Burbidge are right in implying that science doesn't proceed via the clean, unbiased, disinterested use of "scientific method". Theories gain ground for reasons other than their ability to explain the evidence, and conceptual leaps often go beyond available evidence.
There are a lot of books that make these points (Feyerabend's Against Method, Latour's Science in Action). One that I especially admired was Halton Arp's Seeing Red. Arp's observations of anomalous redshifts are cited by Narlikar and Burbidge as challenging the standard big bang model. Arp details his inability to get the astronomical community's ear, or telescope time, to pursue observations that seemed to call into question the very way we measure large astronomical distances (the redshift-distance relationship). I think Arp's book is especially enlightening about how science is done and how the scientific community resists evidence contrary to prevailing models.
