At the beginning of the time and the center of all black holes, there is an infinite density called unusual. To explore this mystery, we take what we know about space, time, gravity, and quantum mechanics, and apply all things simply decomposed. There will be nothing more challenging your imagination in the universe. The physicists still believe that revelation will appear if it can still be consistent with a consistent explanation of what’s actually happening in the unique point. New understanding of space and time.
In the late 1960s, some physicists speculated that unusuality would be surrounded by the decrease in space and time by chance, and the decrease in confusion. Charles Misner at the University of Maryland called it a “mixmaster universe.” Popular kitchen appliances line. If the astronauts are in a black hole, you can imagine that the mixmaster or egg -beter mixes the eggs of the astronauts by mixing the eggs with the yolk of eggs. kip ThorneThe Nobel Prize -winning physicist later wrote.
Einstein’s general theory of relativity, used to describe the gravity of the black hole, explains how spatial curves and materials move using a single field equation. But the equation is A A mathematical shorthand called Tenser To hide 16 clear and intertwined equations. Some scientists, including Misner, devised a useful family to explore scenarios such as the Mix Master Universe.
Without such a assumption, Einstein’s equation could not be solved analytically, and it was too complicated for the numerical simulation of time with them. Like the Appliance named after the name, this idea is in a poor style. “This mechanics should be a very common phenomenon of gravity,” he said. Gerben OlingPh.D. researcher at the University of Edinburgh. “But that’s falling from the map.”
Over the past few years, physics has been reconstructed with a new mathematical tool. Their goals are two. One hope is that misunderstandings and other people’s approximation is an effective approximation of Einstein gravity. The other is to get closer to the unusual, hoping that the extremes will help to adjust the general relativity with quantum mechanics in quantum gravity theory, which has been the goal of more than one centuries. like Sean Hartnoll “The University of Cambridge is now cooked now when this idea is fully developed.”
The birth of mixmaster chaos
Thorne described the late 60’s as the “golden age” of the black hole study. The term “black hole” is widely used. In September 1969, Thorne, who visited Moscow, was manually received by the famous Ukrainian physicist Evgeny Lifshitz. together Vladimir Bellinski And ISAAK Khalatnikov, Lifschitz, used a family designed by three people to discover a new solution to Einstein’s gravity equation. Lifshitz was afraid that Soviet censorship would postpone the publication of the results. Because he was contradictory with his previous evidence, he asked Thorne to share it from the west.
The initial black hole model assumes a perfect symmetry that is not found in nature, for example, that the star was a perfect sphere or no pure charge before it collapsed with a black hole. (This assumption has made Einstein’s equation in the simplest form. Karl schwarzschild Immediately after Einstein’s publication, Belinski, Khalatnikov, and Lifschitz are called BKL Solutions after the initials, the solution can happen in a messy and realistic situation in which a black hole is formed from an irregularly formed object. I explained if it was. The result is not to smoothly stretch the interior space and time, but to be the sea of the universe and time that stretches and compresses in many directions.
Thorne wrote a copy to Misner, who smuggled this newspaper into the United States and thought that he was thinking about it. It turns out that Misner and Soviet group have lowered the same ideas using similar homes and other technologies. The BKL Group also said, “We used it to solve the biggest unresolved problem of the era in mathematical relativity,” said Thorne. BELINSKI, the last surviving member of the BKL Trio, said in a recent e -mail that Misner’s vivid explanation helped to visualize the confused situation near the unusuality they revealed.
