Vanishing of the universe will be "isolated island" composed of.

World Scientific reports [tech.] News: the universe is disappearing <P> It sounds ridiculous, but physicists have pointed out: With the acceleration of expansion of the universe, and ultimately the universe through a telescope to see than the current observed .much smaller. .That is because in a few billion years, perhaps a few trillion years, in addition to our outside of the cluster of galaxies, all other galaxies would fly too far away, is tantamount to permanently disappear. .The results in that distant future, astronomers will study the history of the universe the Big Bang can not get a clue, there is no way to know that we can observe today the existence of giant clusters of galaxies. .Even the Big Bang and most reliable signs of subtle - microwave background radiation will also be out of reach. .</ P> <P> Case Western Reserve University cosmologist Professor Lawrence Krauss said: "Those who are still clusters of galaxies, but the rate of expansion of space faster than the speed of light, so that the light will never galaxies .We can not reach the earth. "</ P> <P> Klaus pointed out that despite the speed limit of the universe is the speed of light, but the above is possible because the galaxies themselves do not actually move, but the various clusters of galaxies .space between the expansion will be greater than the speed of light, causing the light can not be swept through. .</ P> <P> on this theme, Klaus, and Vanderbilt University physicist Richard Scherrer co-wrote a paper to be published in the October issue of "Journal of Relativity and Gravitation ."(JournalofRelativ-ityandGravitation) on. .</ P> <P> dark energy is the "culprit" </ P> <P> result of all this universe is strange and the key component called dark energy. .Dark energy is the vacuum of a growing trend that can create more vacuum itself. .Therefore, the universe, dark energy will dispel any of the things that are not gravitationally bound. .</ P> <P> no one can completely explain the dark energy, but if there is no dark energy, the universe we see today can not understand. .</ P> <P> "of the universe five times" (TheFiveAgesoftheUniverse) is one author of the University of Michigan cosmologist Professor Fred Adams said: "We know that dark energy is generated to follow the laws of physics, .But in the end it does not know what is. "</ P> <P> Year 3 trillion years, astronomers are able to observe the universe to the galaxy only to our group, which by the gravitationally bound galaxies, including .Milky Way and Andromeda, Large and Small Magellanic galaxy and several other smaller galaxies. .These galaxies close enough to each other to overcome the gravitational attraction between the dark energy causing the expansion of the force, so they can come together and eventually become many "island universes (islanduniverses)" a, but these "island universes" can no longer between .can not detect the presence of each other. .</ P> <P> Klaus said that in any one of them "islands" on the observable universe will seem neither expanding nor shrinking, but in a small range of relatively static. .</ P> <P> unknowable nature of the universe </ P> <P> Klaus pointed out that the study across time and space with a revelation that "today we, perhaps impaired head is suffering the pain of .do not know it. " .Adams agreed Klaus point, he said: "The early universe may be a situation occurred, but not Discovery Bale. Therefore, all cosmologists should be especially humble, it is important." .</ P> <P> Adams pointed out that even the existence of such a possibility - in the distant future, the dark energy itself can change. ."We always believe that the universe will continue to accelerate expansion," Adams said, "However, even this situation could change." .</ P> </ p>.
