    Will the universe continue to expand forever, reverse its expansion and begin to contract, or reach a delicately poised state where it simply persists forever The answer depends on the amount and properties of matter in the universe, and that has given rise to one of the great paradoxes of modern cosmology there is too little visible matter to account for the behavior weWill the universe continue to expand forever, reverse its expansion and begin to contract, or reach a delicately poised state where it simply persists forever The answer depends on the amount and properties of matter in the universe, and that has given rise to one of the great paradoxes of modern cosmology there is too little visible matter to account for the behavior we can see Over ninety percent of the universe consists of missing mass or dark matter what Lawrence Krauss, in his classic book, termed the fifth essence In this new edition of The Fifth Essence, retitled Quintessence after the now widely accepted term for dark matter, Krauss shows how the dark matter problem is now connected with two of the hottest areas in recent cosmology the fate of the universe and the cosmological constant With a new introduction, epilogue, and chapter updates, Krauss updates his classic for 1999 and shares one of the most stunning discoveries of recent years an anti gravity force that explains recent observations of a permanently expanding universe.

    1. I just finished Quintessence: The Mystery of Missing Mass in the Universe by Lawrence M. Krauss. The shelf life of a book about an active search in Physics is usually not very long and this was last revised in 2001 however, sadly for the world but happily for readers of this book, there have not been any definitive discoveries since that time. Krauss does an excellent job of presenting the history of the search for missing matter and how the current experiments seeking to validate the competing [...]

    2. The short version first:Quintessence The Search For Missing Mass In The Universe by Dr. Lawrence M. Krauss is a review of the search for a substantial part of our universe which is "dark" to us at this time. By "dark," physicists like Dr. Krauss mean that the matter and energy is currently unassessed by our best scientific instruments, although there is clearly a good deal of evidence that something must exist that makes up what appears to be missing matter and energy which would result in the v [...]

    3. I started reading the introduction and the preface (having already read The Physics of Star Trek, by this same author, the mentor and teacher of Stephen Hawking) knowing he was captivating even when doling out dry facts; he can make them fascinating. So far, I am NOT disappointed with this one either. I am nearly finished with this gets a bit on the heavy side towards the middle and end.Although this is technically my second reading it is much clearer nowd again, despite it being a bit dated, it [...]

    4. I read this for a report in college and really liked it - then, as a senior Physics major, I got to meet Lawrence Krauss! He came to my college to give a talk, and after meeting him he signed a copy of the book for me! He's my science geek idol, right up there with Carl Sagan. *swoon*

    5. review : The Fifth Essence : The Search for Dark matter in The Universepublished 1989Lawrence Krauss5 starsAlthough published almost 25 years ago, this book has in my opinion a very high value for the historical display of the search for dark matter up to the point of publication. I'm not up to date on the latest information in this search, but I think that everything expressed in this text is still relevant. It gives the background for the postulation of theories of what dark matter may be, and [...]

    6. I started this book last december when I was in Siding Spring (the telescope area of Aussie) so I was greatly motivated. it started off very fascinating but then somehow my interest just wore out. i stopped at page 248: "soon after Wilczek and Weinberg announced their theoretical predictions (of the existence of axions), experimentalists began searching for this new particle. while the theory led to definite predictions in most cases for what they should see, all results were negative. by the ea [...]

    7. Well, I got enough out of it to spin a pseudo-convincing scientific fantasy in something I'm writing. That's all I needed it for.

    8. Vähän turhankin "tieteellinen" näin maallikolle. Mutta pureutui aiheeseen erinomaisesti ja kärryillä pysyi. Onkohan tästä tullut uudempaa painosta jotta voisi seurata miten ala on kehittynyt.
