Black holes : The journey of no return ?

                               Black holes : The journey of no return ?

 Black Holes : Black Holes are one of the most facsinating and mysterious objects in the universe. They are formed when a very huge star dies off or collapses on itself to a infinitely dense point having super powerful gravity. The gravitational forces in these bodies is so strong that even the fastest known entity to us light , cannot come out of it. These black holes are so small and even light cannot escape it making them invisible for us to see or spot them in the universe. The boundary of Black Holes is called as 'Event Horizon' .

EVENT HORIZON : The event horizon or the point of no return is the boundary of a black hole. When any matter crosses this invisible boundary it is sucked in by the super powerful gravitational force and is then absorbed in the singularity of the black hole.

How do scientists spot Black Holes : Scientists spot these invisible bodies by observing the matter around it which is been swallowed inside the black hole. The matter around it is swallowed slowly and this allows scientists to accurately spot black holes. Another medium for identifying them is are the pulsar rays shot out by these black holes. These pulsar Rays are not invisible unlike the black holes from where they are emitted and can be spot easily. Black holes can be detected by positioning these pulsar rays.

                Almost every matter close to the black hole eventually enters the event horizon and is swallowed in the black hole. But only 1 or 2 celestial objects amongst millions manage to get away from the event horizon and avoid getting swallowed in. However in this process they pass from behind the black hole and while doing so their brightness increases tremendously( especially stars ). They get back to normal after crossing out from there. Scientists keep an eye on such stars and by just simply observing the increase and gradual decrease in their brightness , scientists are able to position a black hole.

Different sizes of black holes : the size of the black holes differs and this difference is solely based on the mass/size of the star from which it is made. Scientists have discovered black holes of varying sizes but the 2 most common are steller and super massive black holes. The steller black holes are not very big and are found in the the number of thousands scattered across the galaxy. On the other hand super massive black holes are very very big . Black holes at the centre of our galaxy is an example of super massive black hole and scientists believe that there are such super massive black holes at the centre of almost every galaxy.
