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.

In the triple-star system, KOI-5Ab is seen orbiting the primary star...

  KOI-5Ab continues to be a topic of discussion for researchers, as koi-5Ab has been seen orbiting the primary Star, confirming it has also been announced.  koi-5ab revolves around the primary star, it was thought to be a planet half the size of Saturn in a planetary system, and was the only other planet candidate to be detected by the KOI-5Ab mission. Kepler mission operations were initiated by NASA in 2009, by the end of spacecraft operations in 2018, the Kepler spacecraft had discovered 2,394 exoplanets, or planets orbiting stars beyond our sun, and about 2,366 exoplanets such  There are also those, which are still to be confirmed. David Ciardi, chief scientist at NASA's Exoplanet Science Institute, says the KOI-5AB was abandoned, because it was complicated, and we had thousands of candidates, and we were learning something new every day from Kepler, so that the KOI  Mostly forgot to -5. KOI-5Ab is part of the Triple Star system, where KOI-5 is a group of three st...

NASA's Spitzer Space Telescope will be closed.

NASA briefly informed that the Spitzer Space Telescope will be permanently discontinued on January 30, 2020. After about 16 years of discovering the universe in light energy.  And by that time, the space shuttle has been working for more than 11 years beyond its prime mission, Spitzer examines the universe's various objects in infrared light.  It was in 2003 through the rocket that the American Space Research Organization NASA entered the space and entered the orbit around the Earth.  Spitzer rotates the sun on a path similar to that of the Earth but it runs a bit slower.  Today it is about 158 ​​million miles (254 million kilometers) away from our planet - more than 600 times the distance between Earth and Moon.  The spacing of Spitzer's orbit curve means that when the spacecraft indicates its fixed antenna on the earth to download data or receive commands, its solar panels tend to lean away from the sun.  During those periods, to operate the space shut...

SpaceX is preparing for its next mission, very soon Spacex will launch the Dragon Spacecraft with its Falcon 9 Rocket.   SpaceX is the 18th commercial reproduction service mission, dragon spacecraft will be loaded with dozens of experiments made in space.  Launch date: Sunday, July 21, 2019 at 7:35 pm  International Space Station (ISS) us  The National Laboratory SpaceX's dragon is giving a finalization to more than two dozen payloads for launch in a circular circular laboratory.  Many of these payloads are aimed at improving human health on the earth, many of which are focused on drug development.  In addition, a series of payloads from identified private sector partners will be launched on this mission.  More than 40 student experiments and demonstrations have been included on the 18th Commercial Recepti Services Mission (CRS-18) of SpaceX.  One part of ISS American National Laboratory's goal is to encourage and engage next generation scientists.                          ...

NASA's review of the flight design of the Nancy Grace Roman Space Telescope successfully confirmed.

Critical design work for the NASA Nancy Grace Roman Space Telescope has been completed, and the design analysis has also been successfully completed, indicating that all design and developmental engineering work is now complete.  The Nancy Grace Roman Space Telescope is being managed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, along with NASA's Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science stream consisting of various scientists  team is involved. After an analysis of extensive hardware testing and sophisticated modeling, an independent review panel confirms that the observatory we used, said Julie McEnery, senior project scientist for the Roman Space Telescope at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Ready, it will work. Julie McNairy says of the Roman Space Telescope, what we know, what it will look like, and what it is capable of doing, and now th...

A cluster of three galaxies was imaged with the help of the Hubble telescope's camera.

Using the Hubble Telescope's Advanced Camera (ACS) and Wide Field Camera 3 (WFC3), a cluster of three galaxies was imaged.  As shown in the image, the two galaxies have merged, scientists say, just as the two galaxies in the upper right appear to be interacting with each other, it is, in fact, stars.  Its long trails and the gas spreading from both of them gives the impression that these two have just collided with each other very fast.  In the lower left of the image is the bowling-ball-sized galaxy. Scientists say that the interaction between two galaxies occurs over a long time period, however, rarely will the galaxies collide with each other.  These galaxies are so close to each other in space that they form a cluster, which scientists have named NGC 7764A.  The mass between these galaxies has caused the formation of a shape at the end that, from the point of view of our solar system, resembles the starship known as the USS Enterprise from Star Trek.
