Black holes (The birth and the death of black hole)

      Black holes

   Is a region on space and time where gravity is so strong that nothing escapes it even light or electromagnetic radiation. Most black holes are formed when massive stars explodes by super Nova  or hypernova. Most stars are formed by the massive collection of lighter gases which fuses together to form heavier atoms creating tremendous amount of energy by what we call nuclear fusion creating balance between gravity and the radiation created by the fusion.when it reaches iron atom the fusion process stops causing an inbalance between radiation and gravitational force. Then causing a rapid implusion to the star forcing a strong nuclear reaction taking place at the core of the star forming more heavier atoms like uranium. And a supenova explosion takes place creating a black hole. And is not just any star that creates a black hole a star as big and heavy as our sun will create a neutron star and a star 3.5 times as big as our sun will create a black hole

There are 4 types of black holes: stellar, intermediate, supermassive, and miniature.

  📍 The stellar black is as big as an asteriod and as heavy as our sunThey have masses ranging from about 5 to several tens of solar masses.The process is observed as a hypernova explosion or as a gamma Ray burst.these black holes are also referred to as collapsars while the smallest Black hole is xTEJI50-500 and is 24 kilometer and weigh 3.8 times our sun.

📍An intermediate-mass black hole(IMBH) is a class of Black hole with mass in the range 10²-10⁵ solar masses: significantly more than stellar Black holes but less than the 10⁵-10⁹solar mass supermassive Blackhole.         Several IMBH candidate objects have been discovered in our galaxy and others nearby, based on indirect gas cloud velocity and accretion disk spectra observations of various evidentiary strength.

📍 Supermassive Black holessupermassive black hole (SMBH or sometimes SBH) is the largest type of Black hole, containing a mass of the order of hundreds of thousands to billions of times the mass of the Sun. Black holes are a class of astronomical object that have undergone gravitational collapse, leaving behind spheroidal regions of space from which nothing can escape, not even light. Observational evidence indicates that nearly all large galaxies contain a supermassive black hole, located at the galaxy's center.in the case of the Milky Way the supermassive black hole corresponds to the location of SagittariusA* at the Galactic Core the milky way. Accretion of interstellar gas onto supermassive black holes is the process responsible for powering quasars and other types of active Galactica nucleic. This type of Black hole as a billion mass and the largest Ever found is s50014+81 40 billion times the mass of our sun and 236.7 billion kilometer in diameter meaning is 47 times from the sun to Pluto. If you get closer to a black hole or you were to drop inside a black hole time will slow down  as you reach the event horizon as you enter the event horizon time will freeze for you then you disappear 

        Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michelle and Pierre-Simon Laplace. The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958.  And Albert Einstein predicted Black holes in his general Theory of relatively it implies the existence of black holes regions of space in which space and time are distorted in such a way that nothing, not even light, can escape—as an end-state for massive Stars.  

   According to our current understanding all formulas of physics breaks down at the singularity pointCurrent theory suggests that, as an object falls into a black hole and approaches the singularity at the center, it will become stretched out or “spaghettified” due to the increasing differential in gravitational attraction on different parts of it,

The first black hole ever pictured is a super massive black hole at the heart of an elliptical Galaxy messier 87 with a mass of 7 billion times of our sun as depicted in the first image released by the event horizon telescope (10th of April 2019)

         And Black holes Don't live forever they emit what we call the Hawkins radiation which are virtual particles that exists in empty space and this Hawkins radiation it happens slowly at first as the Black hole gets smaller they releases more Hawkins radiation till they die out but this process is so slow that the last black holes will take gagillon years to decay off from the universe kindly visit this site for more.
