Black Hole
Content:
Black holes are one of the most powerful things in this universe with its powerful gravity that even light cannot escape its gravity. This article contains some of the facts about these strange black holes.
How black holes are formed?
Before knowing about the formation of Black holes we must know about the formation of,
Stars: Stars are formed when atoms of light are squeezed under enough pressure which led to nuclear fusion.
Neutron Stars: Neutron stars are formed when a star runs out of fuel (here the fuel is nuclear fusion on hydrogen atoms which forms helium) at this time, the central region of the star get collapsed and all the protons and electrons are turned into a neutron.
Supernova Explosion: After the formation of iron the fusion process stops and gravity starts playing its role it pulls the whole star to the center it crashes the iron and usually electrons don't join with protons and neutrons, but due to the immense pressure by the gravity and the electrons and protons get converted into neutrons, this bounce of the iron core produces a powerful shockwave that explodes outwards, this is called Supernova Explosion and it is visible to the whole Universe. This is indeed create's a Black hole with a super gravitational force that even light cannot escape from it.
A black hole that is 10 times massive than the sun will be about 50-60km wide.
Neutron Star
What if we fall into a black hole?
A black hole that's just a size of a needle could destroy us because of its immensely denser mass and powerful gravitational pull. If our earth goes near a black hole it starts to stretch into matters, this process is called Sphagetification. For an average-sized Stellar black hole, this Sphagetification process starts several hundred kilometers away from the event horizon.
Stellar black hole: This is a black hole formed by the gravitational collapse of a star.
Event Horizon: It is a boundary that defines the space which is around a black hole. Nothing can escape from this region because of immense gravitational pull.
The nearest black hole from our earth:
The nearest black hole from our earth, it is 3000 light-years away from us
In 2015 Hubble (Space Telescope) captured a plasma jet with no trace of where did it originate from and it traveled nearly 98% the speed of light. Scientists then found that it was a plasma burst from a supermassive black hole.
Interesting fact: In the early 90s Mathematician Ramanujan formulated a theory on the black hole but at that time Scientists even don't know that black holes exist in this Universe. In 2005 it was found that the specific Ramanujan's theory was based on black holes and he wrote it before we discovered that there are black holes in this Universe.
There are nearly 100 million black holes on our Milkyway Galaxy.
Conclusion:
This article would be cleared your doubts on black holes, their formations and facts about stars, neutron stars and how black holes absorb matters into it.
