V616-MONOCEROTIS —NEAREST BLACKHOLE TO THE EARTH

Image
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.

White hole

Image
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...

HOLMBERG—15A. (THE BIGGEST BLACK HOLE EVER SPOTTED).

Image
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 ...
