Ripples On A Cosmic Sea: The Search For Gravitational Waves (Frontiers of Science) by David Blair

by David G. Blair

The fascinating story of the race to detect gravitational waves-those magnificent ripples that will finally let us "listen" to the universe In their first book for a general reader, Blair and McNamara weave a thrilling tale about the race to build the first gravitational wave antenna. What these scientists find will allow us to listen to the explosion of stars and the creation of black holes and will undoubtedly chart a new course for astronomy in the coming millennium.

The ripples are the gravitational waves(GW) as predicted by General Relativity Theory. The cosmic sea is space-time itself and the author adroitly described how it is bent by the gravitational force.
First, he explains how GR was proven (e.g. precession of mercury Perhelion, the geometry of the bending of spacetime).
Next, he deviates a little bit when he discusses dark matter and energy since they do not serve as sources of GW. he makes it clear that they have been experimentally found . However, if they exist then there is a plausible explanation for observations. However, until teh Scientific Method is fully applied the jury is still out on their existence.

He moves onto consider sources of GW: colliding black holes, universe's creation bang, binary sun systems involving neutron star, pulsars (fast rotating neutron star). In prep he brilliantly describe various star life-cycles of how you end up with a black hole or a netron star or a white dwarf.

He describes types of Pulsars and how a millisecond versus normal Pulsar is created (some academic therories are discussed).

Next he goes into great detail on how to build a GW detector and why it is still to be further developed. many factors abound in this: reducing noise interference, friction (lowering temp), cost, scale and the uncertainty principle normally applied at a quantum level is also in play here due to the sensitivity required to detect such a weak GW signal.

All in all , the author does a good job of explaining a very technical subject that is in a state of transistion. he lays all cards on the table and illuminates definitions, limitations, state-of-the-art and where he sees the end game.

Good information, while there is some physics, there is also a lot of history.
