Control of the mysterious energy of the universe does exist.

The findings suggest that the last 4 years, more and more like our universe consists of a clever witch with dark energy, dark matter and normal matter modulated into cocktails. .Control the universe, astronomers have discovered a mysterious energy - the latest evidence of dark energy, dark energy may account for the universe that the total energy of the 2 / 3, it is the galaxies and all galaxies with each other at an unprecedented rate .separation. .In recent years, scientists have been looking for the universe not only is expanding, and accelerating expansion of reason. .Some people think that dark energy is a magical object in the distance on the open, thereby overcoming the local effects of gravity. .Recently, Ian University of Manchester. .Blau in an international astronomy team led by the mysterious dark energy for the existence of new evidence. .The scientists observed that, from distant quasars and bright light is bent, the formation of a number of quasars in the image, the image number and the way galaxies formed by the existing number of gravitational lenses do not conform, which scientists have concluded that ., we can not see the way must exist for the other substances, which proves the existence of dark energy in the universe. .Is due to gravitational lensing of light from distant galaxies before reaching the telescope, will be the way of other objects by the gravitational bending of light refraction and the lens is usually similar. .According to reports, a scientist in the astronomy group, including age of the universe, including the use of parameters and the number of possible sources of gravitational lensing, gravitational lens refraction calculated by the number of quasars. .He found that this number is not about dark energy in the presence of twice the number of quasar image. .He therefore deduced that the universe 2 / 3 must be formed by the dark energy. .The remaining 1 / 3 by the dark matter (which still does not know the shape) and composition of stars and planets form of conventional materials. .All these two substances is normal gravitational attraction, that the usual gravity. .The dark energy with them the opposite, with long-range anti-gravity (anti-gravity) properties. .As with the mysterious dark matter, dark energy that scientists did not know what, but these new results add to the credibility of the existence of dark energy. .The scientific community now widely believed that the reasons for the accelerating expansion of the universe. .This new test based on gravitational lensing and the last completely different physical arguments, so it provides support for proof of the existence of dark energy is independent of the other evidence. .Since the formation of quasars by gravitational lensing images usually suffer too close, the astronomy team used the world's most powerful radio telescope array, has been thousands of photos of radio quasars. .They chose the radio telescope, because many times they can to enlarge the details, than even the Hubble Space Telescope optical telescopes see clearly. .Dark energy until 1998 this statement appeared in the field of astronomy. .At that time, two groups of astronomers in distant galaxies, exploding stars or supernovae observed, that the supernova's dismal than they think. .This means that the distance between them farther than scientists had previously thought. .The only explanation for this situation should be, assuming that the expansion of the universe at some time in the past has accelerated. .Astronomers generally believed that before this, because a single drag of gravity caused by the interaction of galaxies, the gradual expansion of the universe is slowing down. .But the supernova observations show that there is some mysterious force in the fight against gravity drag, so that an unprecedented acceleration of galaxies away from each other. .At first, other scientists expressed doubts about the outcome. .Perhaps the supernova light dimmed because they are blocked by interstellar dust clouds, and perhaps optical supernova itself than scientists thought the dark. .But after careful examination, all of these explanations have been swept aside, dark energy hypothesis has emerged. .In fact, the idea of anti gravity is not new. .As early as 80 years ago, Albert Einstein had this anti-gravitational effects of the so-called cosmological constant, including the name of his general theory of relativity. .At that time, Einstein in order not to make the planet due to their mutual attraction between the pushed together, imagine the universe, there should be a repulsive gravitational force it to confront, so that the universe stable. .He put the repulsive force called the cosmological constant. .The last century, 20 years, Hubble discovered that the universe is not static, but constantly expanding. .Einstein gave up his invention of the cosmological constant, calling it his "biggest mistake in life." .Einstein himself and later for many astronomers regarded this only as a cosmological constant is a mathematical assumption, not that it and the actual relationship between the number of the universe. .90 until the last century no one thought of this effect will become a reality. .The discovery of dark energy can now prove the existence of this repulsive force. .It seems that if Einstein were alive, perhaps he would admit, to give up his life in the cosmological constant is the second biggest mistake. .Discussion about a very mysterious dark energy. .Some people think that the universe is dark energy out of vacuum infiltration. .There experiments show that the vacuum does not seem empty, but some virtual particle in the time off to take the lifetime of bubbles. .While some astrophysicists said that dark energy is just the basic features of the universe, trying to explain it, explain why the Earth as the distance from the sun is just as suited to support life in vain.
