Do ringing black holes support the no-hair theorem of gravitational waves.

As simple as a black hole is, it is just as mysterious, because it is not possible to say that a black hole has hair. Stephen Hawking believed that black black holes can have soft hair, if it is,This will be a new discovery.
 Researchers say that in spacetime two black holes collide to create waves, and we can say that bees have no "hair". Where are the 13 physical review papers reported by scientists.This is another way, as predicted by Einstein's theory of relativity, that it is common to predict that black holes have no characteristic properties of mass, and that they spin at the same rate, SN: 9/24 /.  10).

Black holes are simple objects, that is to say, MIT physicist Maximiliano Issy, he believes that black holes are very simple objects.  In 2015, researchers discovered by the Advanced Laser Interferometer Gravitational-Wave Observatory, LIGO, that spacetime waves formed as two black holes collided with each other, causing it to form a large black hole (SN: 2/11/16  ) Spiraled around each other before crashing.  After that event, the newly formed large black hole went through a period of "rigdown", and it vibrated several milliseconds, as it emitted from gravitational waves, the way a tuck tucked, and finally from a calm.First creates sound waves.

The way to revive a black hole is to know the gravitational waves as overtones, not at a single frequency but with additional, short-term frequencies, with bells ringing with several tones other than the main pitch.  The researchers allowed those waves to be compared with the prediction of a blurred black hole, which could measure the main frequency of the ringing black hole as well as an overtones, and this result was agreed to within 20 percent. When the overtones were measured  Gone, this result still leaves some wiggle room to prove some hair theorem to be wrong, and this is a clear demonstration, this method works, the same Oxford universityist  Says physicist Leo Stein's schools, that were not involved in the research, and I hope, that accuracy will increase are improved LIGO.  If the mass and spin of the black hole were calculated, the researchers agreed with the values ​​predicted from the whole data event, including the spiraling and merging of the original two black holes, using only the waves from the rundown period, and the researchers  , Reinforced this idea, that the resulting black hole's behavior was determined solely by its mass and spin.

But just as a bald man can play some varieties, if on inspection of a black hole can reveal some hair, if it happens, this information will become a puzzle for the solution of the paradox.  In an effort to resolve the paradox in 2016, physicist Stephen Hawking and his colleagues suggested that a black hole may have "soft hair" (SN: 4/3/18). It may also be that objects  I have more secrets for them.

The Esa / Nasa Hubble Space Telescope captured the image of cluster 47 Tucanae.

The Nasa/Esa Habble telescope has captured an image of a group of stars, spherical in shape, spanning a large area, this group of stars has billions of stars, these stars have their own color, which is much about them  It says.  In the image we can see, around 35,000 stars are visible near the center of the cluster 47 Tucanae , the stars are tightly packed near the core (top left) of the cluster, and propagate farther away from the core.

In the cluster image of stars, how stars are shown in natural colors, scientists have told about their composition and age through the color of stars, as the star which appears red, the stars end of their life. Is near, bright red signifies giants, while more common yellow stars indicate that these stars are still young, whose age is similar to our sun.

Cluster 47 Tucanae image taken by Hubble's Wide Field and Planetary Camera 2, this image was taken in 1999.

According to Nasa's report the rules protecting other planets from pollution can be very strict

Some scientists believe that the moon will have an interesting mission to seek life, with scientists also considering it as a potentially interesting site to investigate the origin of life on the Moon. But some scientists say that most of the moon is not astrologically interesting. Some places on the moon, Mars and other planets are safe, while some places are unprotected.  Some policies may be too strict to protect the Moon, Mars and other places.

What was the conclusion of NASA's 12-expert panel To review voluntary international guidelines, to keep space missions polluting other worlds with earthly life. These guidelines are recommendations of the international scientific organization COSPAR, which revised policies for spacefaring countries for decades.  Nasa will send a sample-collection mission to Mars next year, the same other space agency also lunar  Interpretation of preparing the trip, as the scientists, there is an urgent need to update safety guidelines of the planets.  A…

How did life begin on Earth? Is it possible by a violent collision on the moon.

The moon, which has many stories to make, did the violent, and cosmic collision during the making of the moon make life possible on earth? This is a big question, but a new study shows that this is true. Science has given many theories about life on earth, but there is always a question in our mind that how life came to be born on earth.Given by science, has many theories, and tries to explain to us how to find elements for life on our planet: such as carbon and nitrogen elements.
Scientists have previously believed that meteorites have brought life-giving elements to Earth, bacteria with meteorites coming from space for example, and the energy of explosions caused by the continuous fall of meteorites from organic matter.Synthesis of. And the isotopic signatures of these elements on Earth coincide with those objects, but what? The ratio of carbon to nitrogen is not very accurate.If we think of transporting the elements that are important for life on Earth due to meteorites, then each p…
