Computer simulations of the collapse of a large star show how such a collapse would end up as black hole. These simulations have successfully predicted the relative frequency of certain types of stars, thus showing they accurately represent the life cycle of "main sequence" stars. It is thus reasonable to assume they are also accurate in representing the end of such stars.
These simulations also show two things:
1) what would be observed during such a collapse.
2) what would be observed long after such a collapse.
Astronomers have observed (1) in almost complete agreement with what the simulations predict. When they look at areas where they think black holes should be, they see (2), further supporting the accuracy of the simulations.
In a few cases, black holes are observed where astronomers saw super-nova centuries ago, further supporting the idea that black holes are super-nova remnants.
What else can I help you with?
What do scientists what to know more about in space?
Black holes
How does a black holes acquire greatest mass?
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.
How do you know blackholes exist?
It is a tricky question because black holes are invisible, but scientists know that they are exist because black holes distort light, so it kind of change the light and also it sucks everything into it, so when scientists see stars starting to disappear, thats mean there is a black hole.

How do people know that there was a blackhole if they don't see it?
Scientists can detect black holes by using x-rays and gamma rays. Black holes still can release matter, and black holes give off a lot off x and gamma rays.
If scientists cannot see black holes and do not know for certain that they exist why might studying them be important?
The assumptions are not quite correct.Scientists CAN see black holes. In fact, black holes are among the brightest objects in the Universe. Of course, light can't escape from WITHIN the black hole; rather, what we see is the accretion disk. Also, scientists are PRETTY SURE that black holes are real. As to why it is important: Black holes are fascinating objects by themselves. They also seem to play an important role in galaxy formation.
Is dark matter excreted from black holes?
No. Black holes do not give off anything other than small amounts of Hawking radiation. That note aside, scientists do not know what dark matter is or what its origin is.
Did scientist send unmanned spaceships into a black hole to gather information?
No, scientists have not sent unmanned spaceships into a black hole to gather information. Black holes are extremely dangerous environments due to their immense gravitational pull, making it currently impossible to retrieve information from inside a black hole using spacecraft. Scientists study black holes indirectly by observing their effects on surrounding matter and light.
Why are you safe from black holes?
Why am *I* safe from black holes? Because the nearest one from my planet is 1600 light years away. I don't know if that means YOU are safe from black holes -- I don't know the distance between your planet and the nearest black hole -- but I know my safety is assured.
What are black holes and how are they identified?
Black holes are the remains of a giant star that has had its gravity collapse upon itself. Black holes suck in any matter that gets within it's gravitational range and smashes it down into tiny particles. It goes inside the black hole of it and is never seen again. Scientists do not know what happens after the matter is sucked in because black holes do not illuminate any light (Its gravity is so strong it pulls in light around it that would normally reveal it). Black holes are identified by a check list of characteristics. (Super massive, Rogue, etc)
How does a black hole suck you up?
Since black holes have a huge mass, objects are attracted to it. Once you reach a point called the Event Horizon, good luck getting out. YOU WILL NOT. We do not know much about death by black holes at this time, but some scientists believe that once you reach a certain point, you will be ripped to a strand of atoms. I do not recommend going near a black hole.
How do you get a black hole?
Virtually all the ones we know anything about probably formed as the result of the death of a very large star, or at the centers of galaxies. Most if not all galaxies have super massive black holes at their centers.
