Hey guys
Explain the formation of black hole in detail .
Answers
Answer:
Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.
Answer:
A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star's life. Some black holes are a result of dying stars.
Because no light can escape, black holes are invisible.
Black holes can come in a range of sizes, but there are three main types of black holes:-
•The smallest ones are known as primordial black holes.
• The most common type of medium-sized black holes is called "stellar."
•The largest black holes are called "supermassive."
Explanation:
According to the given question, we are asked to give the details about black hole formation.
Collapse of Star
When a star bigger than our sun, Collapse a balck hole may" formed. Most of the time when a star collapse it explodes and this explosion is called "Super Nova".
But How star collapse
- Stars collpase when the fuels inside the core gets over.
- All stars has 2 forces by which stars collpase i.e, gravitational contraction and expansion beacuse of fusion reaction.
- When all the hydrogen inside a star is no more then there is no fuel for fusion reaction to occur and thus expansion of star stops.
- Expansion and gravitational contraction are the things by which stars are well balanced and does not collpase. These both have opposite direction.
- Gravitational contraction has direction towards the core where the Expansion has away from the core. So, stars are balanced.
- But when fuels are over, expansion stops and gravitational contraction took over it.
- And THE STAR THUS COLLAPSE
