Voyage To The Great Attractor: Exploring Intergalactic Space
by By Dressler, Alan Michael
Category: Science , General

Seeking to explain how astronomy is made and what he himself does, Alan Dressler tells the story of a decade-long study he undertook with six colleagues to determine whether the universe has expanded smoothly and symmetrically since its creation.He leads us through the research step-by-step. We see close up the background of each scientist involved in the project. We discover how they work together; how their complementary skills - and their differences - are instrumental in their formation of hypotheses about our origins, and how these hypotheses must be proven or modified one by one if we are to find explanations for phenomena that can rarely be directly observed in detail.We watch the team probing intergalactic space and arriving ultimately at the discovery that our Milky Way galaxy and its neighbors are moving toward a Great Attractor - a distant continent of matter, mostly invisible, containing thousands of galaxies.A gripping account and exploration - clear and challenging and poetic - of what drives the scientist to feats of discovery: the search for order and the overwhelming need to know why things happen as they do.
