Only the largest stars, that end as supernovae and leave a core 3 or more times as massive as the Sun in the solar system in which we exist can form black holes. Post-supernova cores that do not reach this mass of 3 solar masses are simply not massive enough to be crunched to the singularity of a black hole. More scientifically, the mass that must be exceeded to collapse into a black hole is called the Chandrasekhar limit, after the physicist, a certain Mr. Chandrasekhar.
What else can I help you with?
How did the first Black hole appear?
Like all the others - Superdense stars collapsing.
What kinds of stars result from death Black holes?
A dead or dying star will start to create a black hole
Do stars began there life in a black hole?
No, but some stars end their life by becoming a black hole.
How many stars did this black hole eat?
Don't know which black hole.
How do stars get to the galaxy?
There are billions of galaxies. Most stars are born in one galaxy but others are pulled in by the huge gravitational forces of the black hole in the centre.
What do stars do when they get old?
Some stars become a black hole or a black dwarf.
Can any black hole turn into a neutron star?
No, black holes cannot turn into neutron stars. Neutron stars form from the remnants of supernova explosions of massive stars, while black holes are formed from the gravitational collapse of massive stars. Once a black hole is formed, it will remain a black hole and will not transform into a neutron star.
Did stars older than the universe create a black hole that resulted in the big bang?
It is a possibility that the Universe resulted from a black hole, and that black holes in our own Universe result in new universes. But all this is extremely speculative.
How to create a black hole?
Creating a black hole is not currently possible with our current technology and understanding of physics. Black holes are formed from the collapse of massive stars, and the conditions required for their creation are extreme and beyond our current capabilities.
What happens when stars go into a black hole?
stars explode
Why doesn't the move?
The sun doesn't move because it is a star. Not a comet, not an asteroid, but a star. Stars may rotate and revolve a little, but they do not move a lot. They are just balls of gas. Except for binary stars, which orbit each other. No others move. And except for stars that somehow wind up too close to a black hole, and orbit the black hole while their material falls into it, until the whole star spirals into the black hole. None of the others move. And except for the sun, which is orbiting the center of the galaxy. These are the only examples of stars that move. Except for all the others.
