It happens when a star 8 times bigger than the sun(if the star is bigger it uses up more fuel/hydrogen)starts to run out of fuel and turns helium into heavier elements and when it finally reaches iron it collapses and turn into a neutron star, then a black hole.

Do black holes just happen?

No. Most black holes form when an extremely massive star dies and the core collapses, becoming a black hole.


How many black holes happen?

It is not known how many black holes exist. One of the main reasons is that, if matter is not actually falling into the black hole, it is impossible to detect.


What will happen if two black holes collide each other?

if two black holes collide, they swallow eachother making one giant blackhole


when will the next black hole happen And what will happen?

most likely in a long time but scientist are detecting black holes coming closer to earth.


What happen when the black hole come?

It is known what will happen. You will get sucked up! But before you get sucked up, Black Holes give flicker of black hot gas. Black Holes have so much power that they can't control it. So that's why they suck up everything in their path. Fun Fact: Black Holes are actually stars that died and contain so much power!!


What would happen if the milky way black hole became active?

It would emit a lot of radiation. Some distant black holes (or more accurately, the area around the black holes) emit more radiation than an entire galaxy. Such black holes are known as quasars.


Do black holes collide?

While we have never actually proven that this does happen, we're fairly certain that when two black holes get close enough together, they will merge and form one even larger black hole.


What are the energy and matter made in a black hole?

Black holes are hidden behind an even horizon we do not know what happen in side them.


Black holes where can you find them?

The nearest know black hole is at a distance of several thousand light-years. There are probably black holes closer by, but they are hard to detect, if they don't happen to be part of a close binary star system.The nearest know black hole is at a distance of several thousand light-years.

What would happen if two black hole were to merge into each other?

You would have a black hole the size of the combined mass of the two black holes.


Does black holes elongate matter that is sucked in?

That's what the mathematical theories suggest would happen. We have never observed this, and with any luck we never will be close enough to see this. Black holes are dangerous places.


What were black holes before they turned into black holes?

stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
