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.

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 shuttle, one should rely on…

SpaceX is launching its next dragon spacecraft.

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.                              …

SpaceX,Dragon Cargo Returns Mission in Pacific ends with SplashDown

SpaceX dragon cargo spaceship dropped at 5:48 pm in the Pacific Ocean.  The EDT (2:48 p.m. PDT) is located approximately 202 miles southwest of Long Beach, California, which is located at the end of the company's 17th contracted Cargo Resipulli mission for NASA.  Spacecraft returned more than 4,200 pounds for other valuable scientific uses. Some scientific investigations of Dragon's return to Earth include: Overview of protein crystals growth, in the use of NASA's biophysics-6, to be interested in cancer treatment and radiation safety  There has been an increase in the growth of two proteins.  Scientists are using ground-based predictions and X-ray crystallography in space to determine that proteins are beneficial in crystallization in microbiology, where some proteins can grow with big and small flaws.Microglio biosynthesis in M…
