Black holes are made just before a star dies. The stars core radiates outward pressure to balance out the gravity pushing down on it. When the cores energy runs out gravity gets the upper hand and compresses the star. As the star gets compressed the core heats up and implodes and swallows itself. The bigger the star the more gravity there is acting upon it meaning a bigger black hole.
If the star is made of tougher stuff it becomes a white dwarf or a neutron star. Hope this helps!

What have black holes got to do with the beginning of the universe?
The density of matter just after the big bang is calculated to be sufficient to have spontaneously created black holes; such are called primordial black holes, and searches for their existence are ongoing.
Is the universe being consumed by the galactic black holes?
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
What if black holes are actually planets with an atmosphere that does not reflect back any light?
Black holes aren't actually holes, they're just humongous 'objects' that are so big that they have huge gravitational pulls and therefore pull everything into themselves, hence the name 'holes'.
Is the amount of black holes in the universe relatively increasing and are the consequences of this a new creation big bang?
The amount of black holes are increasing because the fact that stars are dying and being reborn each second.
Can black holes dies?
Black holes do not die but they can evaporate.
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)
Will the big bang make a black hole?
no black holes are stars
Is the universe made of black holes?
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.
Did you make black holes yet?
Black holes (in the astronomical sense) have never been made in the laboratory.

When was the Why are black holes dangerous answer made?
2010
Why all dead big stars do not form black holes?
All dead big stars do not form black holes because sometimes the collapse of the star is stopped at a smaller size before it becomes a black hole.
How did Dr. Stephen Hawking discover black holes?
He did not. He made some theoretical discoveries about how black holes would probably behave; but the concept of black holes was discovered by others before him.
Are black holes made up of dark matter?
Black holes are not made up of dark matter. Dark matter is a mysterious substance that makes up a large portion of the universe's mass, but black holes are formed from the collapse of massive stars.
What is the composition of black holes, and are black holes made of matter?
Black holes are made up of a super dense core called a singularity, surrounded by an event horizon. The singularity is thought to contain all the mass of the black hole, but it is not made of matter as we know it. Instead, it is a point of infinite density where the laws of physics break down.
Is there any chance of life in a black hole?
stellar black holes, no none at allhawking black holes, no none at allsuper massive black holes at galactic centers, no none at alluniversal black holes, yes we are an example, if the entire universe is indeed inside an ultra massive black hole as would be suggested by the combination of big bang theory and black hole theory
Is the universe being consumed by the galactic black holes?
