On January 1, 1925, 35-year-old Edwin Hubble announced findings that ultimately established that our universe was a thousand trillion times larger than previously believed, filled with myriad galaxies like our own. It was a realization that reshaped how humans understood their place in the cosmos. Six years later, continuing research by Hubble and others forced Albert Einstein to renounce his own cosmic model and finally accept the astonishing fact that the universe was not immobile but instead expanding. The story of these interwoven discoveries includes battles of will, clever insights, and wrong turns made by the early investigators in this great twentieth-century pursuit, from the luminaries (Einstein, Hubble, Harlow Shapley) to the lesser known: Henrietta Leavitt, who discovered the means to measure the vast dimensions of the cosmos . . . Vesto Slipher, the first and unheralded discoverer of the universe's expansion... Georges Lemaître, the Jesuit priest who correctly interpreted Einstein's theories in relation to the universe... Milton Humason, who, with only an eighth-grade education, became a world-renowned expert on galaxy motions... and others. Here is the watershed moment in our cosmic history, splendidly arising from the exceptional combination of human curiosity, intelligence, and enterprise.

One of our most thrilling science writers, has captured the excitement of the amazing years at the beginning of the 20th century when we truly discovered our universe. With a great cast of astronomers and physicists - from Lowell to Hale to Hubble to Einstein - this book is a cosmic delight." (Walter Isaacson, author of Einstein: His Life and Universe)
Greatly informative and full of character. Got me hooked on the people and their lives as well as the developing science and astronomy. Wonderfully written and performed. I have listened to it over and over, still enjoying it.
"Worth the Effort"
I try to read in unfamiliar areas every week and so I looked to "The Day We Found the Universe" and was not really disappointed. I further seek out books that are well written and read as well as informative. This book met those expectation.
In this volume Marcia Bartusiak has done an exceptional service by making this scientific story available to general readers. Her section dealing with problems of positivism in research were refreshing.
This book has enabled me to understand the contributions of Einstein, Harlow Shapely, Hubble and others to the understanding of our universe, its size and significance. Sections on Hubble were very interesting. Pages on how Einstein developed his theoretical perspective was warming. All of these players become real and human in the reading.
Readers who need to be entertained to maintain interest might be a little disappointed in this volume, however. The prose is wonderful, but will not carry the reader along on its own. Readers and listeners alike will need to concentrate or they will not benefit. Those without any background will, perhaps, not understand everything covered. There is a lot here to benefit the novice reader coming to this topic with an open mind and a the willingness to "listen up."
"nicely drawn history of the idea of galaxies"
This book is a well done history of the emergence of the idea of galaxies or island universes from the 19th to the mid-20th century. The people such as Shapely and Hubble are portrayed with their foibles as well as their more admirable qualities. The narration is quite good.
"Interesting book/monotonous narration"
This book describes in an accessible language the great controversies of early twentieth century astronomy. Bartusiak also doesn't not leave out the characters involved, delving into the personalities, quirks and aspirations of the influential astronomers of era. It does so without dumbing down the science.
Unfortunately, the narration is less than stellar. The narrator proceeds at a good pace but reads almost every sentence with identical intonation.
"A history of astronomy I didn't know well"
I always thought that Edwin Hubble sort of single handedly discovered that there were other galaxies beside our own, expanding the universe tremendously. But this book has set the story straight. Basically theories have gone back and forth between the idea of island universes and "the milky way is the only universe".
It's also interesting that the book goes on after Edwin Hubble proved other star systems were far beyond the realm of our galaxy. Because he (and his collegues) also discovered that the galaxies were moving away from us. It's funny to hear that even Hubble thought "that can't be right". But it was. And it let to Lemetre's theory that the universe is expanding. And if you track those movements of the galaxies back in time, you get to a point in history where they all originated from. And the big bang theory.
One of the better audio books about physics and astronomy. I could easily follow the narration while commuting. The narration can be a little monotome, but it's not that off putting.
"A wonderful book for anyone who enjoys astronomy"
I have not seen the print version
I frequently enjoy books on science topics and this fits right in. This one is different in that it is not about the science but how the science evolved through the hard work and the politics of science. Through mutual support and competition the science of astronomy is advanced and expanded.
I have not.
This was more of an enrichment experience. I am a new amateur astronomer with less than a year into the hobby. As such I am fascinated about everything to do with astronomy. Hearing how we have gone from theory to theory as new information was revealed was very rewarding. The book is about people stretching to know more, just as I am stretching to know more.
I really enjoyed the story and the presentation. This is not a novel with lots of witty dialogue so if that is what you seek, look elsewhere. This is not a textbook course on astronomy. It is a history story of emergence from ignorance to enlightenment and how it happened. I plan to listen to it a second time soon to get more of the depth that I might have missed the first time.
"We need more like this!"
It would be nice to have books of this quality for many other historical reviews of scientific progress. Developments in spectroscopy, discoveries in electricity and magnetism, selected discoveries in biology, botany, geology, stellar dynamics etc. "The Day We Found the Universe" had just the right balance of technical and history information. Great purchase.
"An excellent book"
For any interested in the techniques and history of Astronomy this is an excellent book and well worth the reading.
