Black holes - Different theories
First theory of black holes
Black hole is a region in the midst of the "MILKY WAY", formed from a constellation of stars, which have either died or have lost their existence in space. The gravity near black hole is much more than any other planets. It is said that the gravity is of such higher order that even a single ray of light entering in that region will lose forever, it will not retrace back.
The basic concept of black hole is that when more and more mass is added to an object by keeping the size same the object becomes a black hole or by keeping the mass same and squeezing it within the critical radius the object will also become a black hole. When stars are formed, black hole the second process is carried out that is by keeping the mass same the stars are squeezed so much that they become but for this you need a large amount of mass which is not present in sun but the other big stars can be black hole.
We know that the stars move round itself and we know that it also have some atmospheric pressure for the rotation around itself. When the stars become old, then its rotation around itself increases so the pressure also increases and it increases so much that it pressurizes the star from all sides and by this the star is compressed very much and the mass remains same because the pressure from all side dose not give any mass to be vested or go away by which it becomes a black hole.
For example if mass is 500 times more, then the mass of solar system will be compressed to the size of sun and then it will become a black hole.
Second theory of black holes
The black hole is like an opening of a tunnel. Black hole is the one end of the tunnel and the other end is known as white hole. The tunnel can be sad as a tunnel through space-time. The two ends are not just in two different places but they are in two times in the space. The work of black hole is to suck stars and the work of white hole is to exert the thing that is sucked by a black hole that will be taken out by white hole. It makes a tunnel through space-time because it has tremendous gravitational force which makes a hole through space-time or tunnel through space-time and by this time travel is also possible. Time is like a river which hoes on flowing. We can go back or front by creating a wheel pool in the river of time which is flowing in space and to do this, we need great energy and one of the source is black hole but other ways are also there.
Third theory of black holes
Black hole is not just present in the Milky Way, but it is also present in other galaxies. Each galaxy has a supermassive black hole present in its middle. Milky way also has one. A black hole is created when stars 150 to 200 the mass of our sun collapse under intense gravitational pull. Objects around the black hole move with tremendous speed and this helps us to identify a black hole. A black hole emits no light, so it is identified by the dense cluster of objects around it moving under tremendous speed. A black hole and a supermassive black hole are different. A supermassive blackhole is 100 times larger than an ordinary black hole. In a black hole, any object is ripped apart and exists in it as magma. In a supermassive black hole, a thing experiences free fall and then it is shredded to pieces. An object present within 100 million km of a black hole is sucked into it. Others revolve around a black hole.
Fourth theory of black holes
How black hole is created? Take a massive star having mass of 1.5 times or more than the mass of sun. At the centre of this star, continuous fusion reaction is going on, creating newer and heavier elements. Heaviest elements gather at that center of the star. When it runs out of its fuel, i.e., hydrogen, it collapses under its own gravitational pull. Inner dense mass implodes onto itself while outer layer explodes, what we see as SUPERNOVA. This causes further compression on inner massive core to a radius which makes under root 2GM/R (i.e. escape velocity) more than the speed of light i.e. 300000 km/sec which means even light rays traveling at a speed of 300000 km/sec cant escape its gravitational pull. If light rays cannot, nothing can. This giant is what we call black hole. The radius of event horizon which is the boundary of space time may be as small as a few thousand kilometers depending on the mass of black hole.
So these are four different theories of black hole. Lets discuss them further in the comment section below. If anyone wants to put down their own theory about black holes, they are also more than welcome.
