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 behaviour we can see. Over 90 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 and shares one of the most stunning discoveries of recent years: an antigravity force that explains recent observations of a permanently expanding universe.
