Scientists map the strange, chaotic spacetime in black pit


Original version one This story appeared How many magazines.

At the beginning of time and the central center of every black hole is the endless density point. To explore this Enigmas, we get our knowledge about space, time, gravity and quantum mechanics and apply all of these things to the place where all of them are broken. There is nothing in the universe that forms more imaginary. Physicists still believe that a suitable explanation for what happened in and around and around, perhaps, perhaps something will appear A new concept of space and time.

In the late 1960s, some physicists can be covered by a rough region of solitude, space and time can be surrounded by an area where the place and time are zapped and shriveled. Charles Misner of Maryland University called him « Mixmaster Kainat », then after what Popular line of kitchen appliances. If an astronaut had to fall into a black hole, « can a mixture of astronaavut could be confused by the winding of a mixture or egg unit in a blower of an egg » Kip ThorneNobel award-winning physicist, wrote later.

The common relative theory of Einstein, used to describe the weight of black holes, uses a single field equation to explain how space curves and articles are moving. But this equation uses a The mathematical shorthand called a tensor 16 different, to hide the equations near each other. Several scientists have prepared assumptions that allow you to investigate scenarios such as the Yanfer, the Mixmaster universe.

Without these assumptions, Einstein’s equation could not be resolved analytically, and even with them were very complicated for the numerical simulations of time. As they are called the device, these ideas have fallen out of style. This « dynamics is expected to be a very common event in the force of gravity, » he said Gerben OlingA postdoctoral researcher at the University of Edinburgh. « But it’s something that falls from the map. »

In the last few years, physics revise the chaos around the subjects via new mathematical means. The goals are double. One hope, Disner and the rapprochements of others are to show that the Eynseian gravity is reliable. The other will help a very century aimed at a very century to make a general relative connection with a quantum mechanics with a quantum mechanics in a theory of quantum gravity. Like Sean Hartnoll Cambridge University « Time to develop for these ideas. »

Mixmaster chaos Birth

Thorne described the end of the 60s as a « golden period » for a black hole study. The term « black hole » was made only for widespread use. In September 1969, the visit to Moscow was given a manuscript by Evgeny Lifthitz, who was a prominent Ukrainian physical physical in Moscow. Together with Vladimir Belinski And Ishaq Khalatnikov, Lifschitz, Einstein found a new solution to the weighted equations near a loneliness, and three used the assumptions prepared by three. Lifthitz, Soviet censors postponed the publication of the result, because this was condemned that he asked Thorne to share the West.

Previously black hole models, for example, a star was supposed to be the perfect symmetry of a star before falling into a black hole or a net electric charger. (These assumptions were allowed to solve Einstein’s equation in the simplest form Karl Schwarzschild Einstein after publishing them.) After the solution of BKL, the settlement of BKL, which is a solution to BKL, a mixture of a mixed, mixed with irregularly unimagained objects described in a more real situation. The result was not a smooth stretch of space and time, but a space and time stretching in many directions.

The Thorne paper returned to the United States and sent a copy to the Disner that he thought along similar lines. It turned out that the Disner and Soviet group used similar assumptions and different techniques to independently independently in the same opinions. In addition, BKL Group « After that, he used to solve the largest unresolved problem of this period, » Thorne said about the existence of those known as « general » loneliness. Belskinski, who recently had the last survivor member of the BKL trio, in turn, helped Disner’s live statements to imagine the chaotic situation near the loneliness.
