BLACK HOLE SWALLOWING THE NEUTRON STAR Black holes are considered as giant hunters which are hungry for matter. They swallow every thing made up of matter. This time scientists have discovered a black hole swallowing it's nearby neutron star.  Scientists may have detected merger of black hole and neutron star. 900 millions years ago, black hole and neutron Star started merging which cause gravitational ripple in space-time fabric which was detected in last week at ligo and Virgo by highly sensitive light interferometer which is specially developed for detection of such type of gravitational waves.  Scientists from LIGO and VIRGO have claimed  that it is gravitational waves candidate. When two bodies in space time with very high mass interact with each other this causes conversion of mass into energy in form of gravitational waves.  The intensity depends on masses of two black holes or other celestial bodies. Scientists have observed the binary black holes or bina

GHOST PARTICLE (NEUTRINOS)      A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly difficult to detect. SPIN :   1/2 (chargeless) TYPES :               1. ELECTRON               2. MUON               3.TAU Neutrinos are termed as ghost particles because the scientists think, it is too  hard to detect  neutrinos as they are Massless and can't react with matter. It can pass through matter like earth, sun. Even billions of neutrinos still are passing through your palm but you don't know. Then how can we study these type of particles? As they are Massless or even can't react with ordinary matter, they are considered from one of the family of dark matter. But recently team of scientists successfully measure mass of t

PULSARS PULSARS are highly magnetized neutron star which is rotating at high speed . It is White dwarf or neutron star which emits electromagnetic radiation. Pulsars have strong magnetic field which funnels jet out particles in form of radiation. This radiation can be detected only if radiation points towards earth. This particles create a beam of light. Three distinct classes of pulsars are currently known , according to the source of the power of the electromagnetic radiation: 1. Rotation-powered pulsars , where the loss of rotational energy of the star provides the power, 2.Acceration power pulsars where gravitational potential energy of accerated matter is power source.  3.Magnstars where decay of electromagnetic field of pulsar provide power.  APPLICATIONS:                                     pulsar are used to find unobservable celestial object known as neutron star which rotates near to speed of light.   Milliseconds pulsar allowed to test        G

FIREWALL PARADOX( MONOGAMY OF QUANTUM ENTANGLEMENT)  QUANTUM ENTANGLEMENT Quantum entanglement is phenomenon in which group of particles generate and react with each other in way such that the quantum state of one particle cannot predict independently state of others,even they are separated with long distances. REASON BEHIND PARADOX According to quantum physics of curved space time and single emission of hawking radiation include only single entangled particles. The outgoing particle escapes and is emitted as a quantum of Hawking radiation; the infalling particle is swallowed by the black hole. Assume a black hole formed a finite time in the past and will fully evaporate away in some finite time in the future. Then, it will only emit a finite amount of information encoded within its Hawking radiation. Assume for time  , more than half of the information had already been emitted. According to widely accepted research by physicists like Don page the outgoing particle will b

SAGITTARIUS  A* SUDDENLY  FLASHING 75 TIMES BRIGHTER  SAGITTARIUS A*  is super massive  black hole at Center of our galaxy. It has 22 million km long radius. It is compact radio wave source which is situated at Sagittarius constellation. It is nearly 25640 light years away from earth.  It weighs 4 million solar masses. It's apparent size is 100 millionth degrees means watching tennis ball kept on moon from earth.  SAGITTARIUS A* IS GLOWING 75TIMES . There is something surprisingly happening in heart of our milky way. Sagittarius A* is too calm and take type black hole. He is not eating too much now,but eventually it started flared up 75 times than normal.  Researcher observed that Sgr A* is glowing 75times and luling  down. Scientist have  said this yo-yoing observed 26000years ago. Scientists from WM Keck observatory ,Hawaii took two hours lapse video of this wonder.Black hole always flash but this time it is too much flashing.                                 

DARK ENERGY Dark energy  is unknown form of energy hypothesized to permeate all space and responsible for expansion of universe which decrease temperature as well as oppose gravitational pull. Every object in universe appears moving away from other object due to expansion of space .  Dark energy is the most accepted hypothesis to explain the observations since the 1990s indicating that the universe is  accelerating at very fast rate.   Dark energy  is not  negative energy . It causes a repulsion because of its unusual equation of state, which causes it to behave as if it has a  negative  pressure. ... It's not obvious that the  energy  of the universe or the gravitational potential  energy  of the universe is a well defined and useful concept BIG  FREEZE  THEORY  Observations suggest that the expansion of the universe will continue forever. If so, then a popular  theory  is that the universe will cool as it expands, eventually becoming too cold to sustain life. F

RELATIVISTIC JET FROM BLACK HOLES Black holes are monsters but this monsters can't be detect by observing using telescope. Black holes are too massive that even electromagnetic waves which are at speed of light.            Therefore ,there is no chance to detect black holes on basis of detection of radiation. Black holes engulfs all stuff which come in its way. But how much will it eat? What will happen to all it's mass engulfs by it?  The mass which black hole engulfs increases it's mass but when it overeat it shows some signs of hope to detect it. Black holes eject relavistic jets from it's center which sparks through out the universe.  Relativistic jets                                                An astrophysical jet is an astronomical phenomenon where outflows of ionised matter are emitted as an extended beam along the axis of rotation. When this greatly accelerated matter in the beam approaches the speed of light, astrophysical jets

 IS DARK MATTER OLDER THAN OUR UNIVERSE  ? Dark matter is major contributer for mass distribution, nearly 85%of universe mass. Dark matter is formed mostly in cosmic expansion time after Big Bang.  According to new studies, scientists believed like dark matter is older than universe. New studies showed that dark matter started to formed, when space was expanding very fastly.The constitution of Dark matter most mysterious elusive .  The study published in physical review letters presents how dark matter was formed and how it might be identified in coming decades during astronomical experiments.  A new Johns Hopkins University study suggests dark matter may have existed before the Big Bang.  "This new study shows relationship between particle physics and astronomy.   " says Tommi Tenkanen, a postdoctoral fellow in JHU’s Department of Physics and Astronomy and the study’s author. “If dark matter consists of new particles that were born before the Big Bang,

HOLMBERG — 15A THE BIGGEST BLACK HOLE EVER SPOTTED  Millions of black holes live in our galaxy Milky way. Black hol Esta are known for their gravitational pull, having escape velocity greater than speed of light. They are too massive. Scientists are looking for such black holes for further studies. In this process,  they came across a black hole which is nearly 40 billion times massive than sun which is more than black hole found in M87 galaxy which is nearly 16 billion times massive than sun.  HOLMBERG-15A is the biggest black hole ever spotted.  Holmberg 15A is a supergiant elliptical galaxy and the central dominant galaxy of the Abell 85 galaxy cluster in the constellation Cetus, about 700 million light-years from Earth. It was discovered c. 1937 by Erik Holmberg. The black hole is nearly 700 millions light year away from earth.  Researchers state that the brightest cluster galaxy (BCG) of the cool-core cluster Abell 85, consists of an ultra-diffuse cent

V616 MONOCEROTIS —  THE  NEAREST  BLACK  HOLE  TO  EARTH MILKY WAY  has millions of black hole. Our galaxy has super massive black hole at it's center  SAGGARITUS A which is too much powerful, but it is too far from earth.Black holes are destroyer. They engulf everything which is full of matter. Then question arises is there any danger to earth from any black hole?  As per observations V616 MONOCEROTIS is the closest known black hole from earth.  It is also known as A0620-00. This system is binary star in MONOCEROUS constellation.  This constellation only contains two objects.  SIZE   = APPROX (LONDON CITY)  DISTANCE FROM EARTH -   3457  light years MASS OF A0620-00 =   6 TO 9  TIMES OF SUN The black hole in A0620-00 pulls matter from the K-type star into an accretion disk.  The accretion disk emits significant amounts of visible light and X-rays. Because the K-type star has been pulled into an  elliptical  shape, the amount of surface area visible, and th

THE STAR BAFFLED SCIENTISTS WHICH LOOKS OLDER THAN OUR UNIVERSE  The age of our universe is 13.8 billion years. Scientists found a star who baffled them by it's age. Scientists have discovered star whose age is 14.5billion years. Now question is can our universe have stars older than itself?  This is condrum that universe is younger than its some stars.  HD 140283 : HD 140283, informally nicknamed the Methuselah star, is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, specifically toward Ophiuchus. Its apparent magnitude is 7.205.   It's a riddle of cosmic proportions: how can the universe contain stars older than itself?" physicist Robert Matthews  wrote for  The National ,  an English-language newspaper published in UAE. It could spark on new scientific revolution.  Dr Matthews, a member of the UK's Royal Astronomical Society, said recent measurements of the cosmic background radiation left over a

THREE BLACK HOLES MERGING Scientists have discovered a trio black holes lock in cosmic dance death.  Black holes are considered as monsters of space. They engulf everything and sometimes other black holes also. Scientists have observed trio death dance of three super massive black holes which named    SDSS J0849+1114 Each behemoth is likely to be emitting huge spurts of gravitational waves as they swirl around each other. The threesome forms a massive system called SDSS J0849+1114, which is believed to be made of three holes locked in orbit.  When two black holes collide which each other.,some of the energy from collision is converted into gravitational waves. These gravitational waves is one of the Einstein gift for us humankind to learn general relativity.  This trio will also loose energy in form of waves. An international team of stargazers believed they’ve found a rare ‘triple system’ of galaxies with gigantic monster black holes at their core. This sys

WHITE HOLE In general relativity, a  white hole  is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black  hole  which can only be entered from the outside and from which matter and light cannot escape. White holes are considered as one of the outlet for another universe. White holes expel out mass and energy.  White holes are door  for entering new universe. White holes combined with black hole can form a wormhole. Some scientists believed on multiple which binds each others by black hole and white hole.  It is reverse of black hole. As any object enter in black hole nearly at speed of light, in case of worm hole it will thrown out in new universe or at distant place with almost speed of light.  The possibility of the existence of white holes was put forward by Russian cosmologist  Iron Nogovic. White holes still are hypothetical  Here

FIRST STAR ESCAPED TO MILKY WAY'S BLACK HOLE -  S5-HVS1 Black hole is the one of the giant in space. Even fastest thing can not escaped from it's  gravitational force. Gravitational force is the weakest force among all four forces but black hole shows it's still too strong . Black hole is so dense point in the  4 dimensional  space -time which has tremendous mass in single point. According to scientist ,black holes plays important role in formation of galaxies. Every galaxy has one massive black hole at it's  center. The stars in vicinity of black holes revolve around black hole with elliptical path. Even our MILKY WAY also has Saggiritus a.  Sagittarius A  is so massive black hole but still S5-HVS1 manage to escape from it's gravitational pull.  The gravitational pull of these behemoths is so enormous that not even light can escape – which is why we can’t just look into the night sky and ‘see’ one. Now scientists have discovered a star which was lu

Through the wormhole Science fiction is filled with tales of traveling through wormholes. But the reality of such travel is more complicated, and not just because we've yet to spot one. The first problem is size. Primordial wormholes are predicted to exist on microscopic levels, about 10–33 centimeters. However, as the universe expands, it is possible that some may have been stretched to larger sizes. Another problem comes from stability. The predicted Einstein-Rosen wormholes would be useless for travel because they collapse quickly. "You would need some very exotic type of matter in order to stabilize a wormhole," said Hsu, "and it's not clear whether such matter exists in the universe." But more recent research found that a wormhole containing "exotic" matter could stay open and unchanging for longer periods of time. Exotic matter, which should not be confused with dark matter or antimatter, contains negative energy density and a la

WORM HOLE ARE TIME TRAVELING MACHINES A  wormhole  is a sort of tunnel that joins distant points in space, or even two universes, via space-time curvature. Theoretically, such a tunnel could be traversed from one point in space to another without actually traveling the distance between them.  In the 1980's, Thorne, who is the Feynman Professor of Theoretical Physics, Emeritus, at the California institute of Technology, kicked off a serious discussion among physicists about whether or not an object (like a spaceship) could physically travel through a wormhole. In other words, do the laws of physics forbid it? Or, with unlimited resources and knowledge, could a civilization build a wormhole ? Physicists, including Thorne, have made some progress on this question. Scientists knew prior to the 1980s that if wormholes existed, they would evaporate before anything (even light) could pass from one opening to another. So sending something through a worm
