The mystery of black holes suck the magnetic field to display their heart Dafa.

<P Align=center> </ P> <P align=left> "swallow": from the black hole and the normal star binary system consisting of X-ray spectroscopy shows that millions of gas cyclone swirling around the black hole, so most of the heat .inside a black hole to spiral to the expansion, about 30% of the gas is dispersed into the universe. .</ P> <P align=center> </ P> <P align=left> "spit": J1655 black hole wind-driven magnetic field, magnetic field due to pressure of the gas disc and the disc to the outer expansion of the energy away .</ P> <P align=left> along, scientists know that the universe black hole is surrounded by downed the stars to ever-expanding substances, but it is how to eat, how to digest these substances, has been a mystery. .Recently assistant professor of astronomy at the University of Michigan's science team, led by Jon Miller, found the answer: they are by Chandra X-ray telescopes in our galaxy, the discovery of a black hole of black hole X-rays emitted gases, thereby exposing .On one of the major mysteries of the universe --- the mystery of the black hole throughput: it is "swallowed" go on, and ultimately bound to "spit" out. .Only in this way, the universe is possible to keep material and energy balance. .The findings are published in the June 29 issue of the British "Nature" magazine. .</ P> <P align=left> the black hole system was found to be named J1655. .Miller said: "According to international rules the galaxy, J1655 is our neighbor, so we can learn about all the black hole through its features, including our quasars found in the strange phenomenon." </ P> <P align=left> magnetic field .Help to display the black hole "suck the heart Dafa" </ P> <P align=left> Miller found that the black hole system through a strong magnetic field rather than gravity to gravity around the planet constantly absorbing material (gas and dust) disk into your .. .In this process, these substances began to run away from the direction of the original deviation to the black hole, thus forming "angular momentum" (described in the physical objects around the axis), that is, black holes can absorb the resulting stream of matter and energy .. .The direction of the gas to be changed gradually formed around the black hole growing one, called "speed zone" of the ring, like Saturn's rings the same. .In the "accelerating region", the large number of hot gas around the black hole rotation. .</ P> <P align=left> more as more material absorption, the black hole has angular momentum must split in order to provide continuous influx of material and energy space. .Say, like a huge water tankers, in order to maintain the rotation, it must release into the water, while the same amount of water. .Black hole is so, it must absorb the material while the corresponding energy release. .</ P> <P align=left> 30 years, scientists assumed that the disc friction between the magnetic material, so that the formation of romantic disc from the inside out, and to the external gas inward diffusion. .Chandra X-ray telescopes now provide us with a crucial evidence that black holes formed in the process of magnetic force to occupy an important position. .</ P> <P align=left> two ways to help black out "pour" </ P> <P align=left> Miller found that when the disc is compressed by the friction of these materials, they will make a round .disk heating, and the release of X-rays. .However, astronomers have long known friction alone is not sufficient to allow the gas from the black hole. .Could spiral into a black hole in the gas before the gas must release its orbital angular momentum, in order to "escape" the black hole, otherwise it will remain in orbit around a black hole movement. .</ P> <P align=left> In fact, in addition to friction, the magnetic field can also help the wind energy a black hole release of substances. .Miller team found that the magnetic field rotating in the wind "speed zone" of up to 500 kilometers per second speed, part of the material and energy thus by its "drive" back into space. .Ultimately, the research team believes that the wind field of molecular friction and the material inhaled the black hole energy and the energy is released to balance the material. .</ P> <P align=left> to prove their theory, Miller and his colleagues used computer simulations of the magnetic wind, and through the Chandra X-ray telescope to observe the Milky Way black hole wind, and compare their features. .Finally, Chandra X-ray telescope sent back data show that black holes wind operation mode and computer simulation of the magnetic field exactly the same style. .This result is very excited to Miller and others, but Miller still calmly said to prove the existence of the wind field is still just their first step to explore the black hole growth. .</ P> <P align=left> However, until now, scientists do not know how the angular momentum is to be released, but they suspect that is because the turbulence caused by the magnetic disk. .Disc turbulence generated friction, the formation of an inside to the outside away from the wind, the wind away angular momentum, which allows material falling into the black hole. .</ P> <P align=left> black holes there are still many mysteries </ P> <P align=left> Miller said in an interview, this finding is an important step in understanding black hole growth and its potential significance is .far-reaching. .This work is to find growth in other similar stars, the magnetic field is also very important roles, such as neutron stars and white dwarfs, astronomers study will lead to more growth in other similar stars to see if they have magnetic disk magnetic field generated by the wind. .</ P> <P align=left> But while this understanding is important, but only the first step. ."We need more detailed observation. Chandra X-ray telescope that we have an important glimpse of the future will have more detailed emission to confirm the details of the black hole swallowed." Including the disc magnetic field work? .The number of substances into a black hole? .How the role? .Magnetic field is not there a black hole like a snake coiled stage? .The back is not the same as the porcupine's bristles extending from the disc to a thing? .And so on. .- Compile / Wang, Jin and Yuan </ P> <P align=left> black hole is a hole in it? .</ P> <P align=left> "black hole" it is easy to imagine him as an words too literally, "big black hole", does not. .The so-called "black hole", is such a celestial body: it's gravitational field is so strong that even light can not escape. .According to general relativity, gravitational field will bend space and time. .When the star of great size, its gravitational field on space-time had little effect on the surface from the star made a point of light can move in any direction along a straight line shot. .The smaller the radius of the star, its surrounding space-time bending the greater the angle of the light emitted towards some will return to the stellar surface along the curved space. .</ P> <P align=left> small radius of such stars to a specific value, even the light emitted perpendicular to the surface were captured. .By this time, the star becomes a black hole. .That it was "black" refers to it as a bottomless pit of the universe, generally think that if any substance to fall into, "seems" to no longer escape. .</ P> <P align=left> stumped Hawking's black hole </ P> <P align=left> 1975, the British physicist Stephen Hawking made the famous "black hole paradox", claiming that a black hole formed, began to .outside the radiation energy, will eventually disappear because the quality is lost. .Once the black hole disappears, inhalation of the black hole information is lost. .Hawking became famous for this theory. .However, in July 2004, Hawking reversed his theory 29 years ago. .He said that the black hole will not enter the information in their border submerged objects, but this information will be "shredded" after the release out. .</ P> <P align=left> the starry sky for black holes </ P> <P align=left> clear night, people are overlooking the stars in the sky Why do some stars so bright? .Scientists estimate that since the Big Bang, the universe, half of the rays are not from the black hole swallowed the success of substances, including the brightest quasars. .These are black hole "give up" the loss of the material with a light to the universe, the formation of stars shining planet. .That is, black holes light up the universe. .</ P> <P align=left> Chandra X-ray telescope, the latest data available for the first time shows the high density of black holes have such a strong magnetic field is the key to the phenomenon of light. .</ P> </ p>.
