Formation of black hole? but how are stars of theUniverse formed how?

Answer 1

Here is your simple answer:

All you need to create a star is Hydrogen and that annoying thing we call GRAVITY.

get enough hydrogen floating about...it will come together as a sphere (of course)...if there is enough hydrogen, the sheer mass of it all pushing towards the center (following the tenets of gravity), will make the Hydrogen atoms at the very core of the sphere to heat up due to friction (theyre being squished together with immense force) as they bounce off each other. if the temperature at the core can manage to reach approximately 2,000,000 degrees Celcius, Nuclear fusion will occur. the chain reaction will kickstart the sphere of Hydrogen into a star essentially. two Hydrogen atoms will fuse together to form one Helium atom...and lots of energy as a byproduct...eventually the Helium atoms too will fuse to make one Nitrogen atom...and so on and so on....for some billions of years.

And your star is born.

so in a nutshell....

1. Hydrogen
2. gravity
3. increasing core temperature due to friction
4. 2 million degrees Celcius is reached
5. BINGO!....nuclear fusion....(that's what stars are, big nuclear fusion engines)

Answer 2

The second part of nicklemeout's answer is correct that stars come from other exploded stars that leave behind clouds of particles called a nebula. These gigantic nebula can also start shrinking from a nearby star's explosion as well as from collisions of clouds.

But he's wrong about neutron stars turning into black holes. Neutron stars form when a star with between 2 and 3 times the mass of our sun explodes.Then neutrons have enough force to keep the sun from shrinking into a black hole. Black holes are created when the exploded star had more than 3 times our sun's mass. Then even neutrons do not have enough force to keep that sun from shrinking into a black hole.

Answer 3

Nuetron stars are usually the main beginning sources of black holes. The nuetron stars form from dying stars. To put it one way, the star collapses on itself and the matter becomes tightly packed and turns into a super magnet.

Now, other dying stars have the potential to explode into supernovas. When this happens, it spreads the molecular gasses throughout space. When two of these collide, they some times begin the process of forming another star - called a protosun. If the colliding nebulas - which is what they become - have angular motion, then they will eventually produce the planets. Essentially, we are all made up of stars.
