Black holes are made of extremely dense matter that has been squeezed into a small space. They form when a massive star collapses under its own gravity at the end of its life cycle. This collapse creates a gravitational pull so strong that not even light can escape, creating a region of spacetime from which nothing can escape, known as a black hole.
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.
White holes are theoretical objects that are the opposite of black holes. They are believed to be created as a result of the mathematical equations that describe black holes, but there is no observational evidence of their existence. In theory, white holes would expel matter and energy outward, in contrast to black holes which pull matter and energy inward. Their role in the universe, if they exist, is not well understood, but some scientists speculate that they could potentially be connected to the creation of new universes or play a role in the recycling of matter and energy.
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.
Black holes are formed when a massive star runs out of fuel and collapses under its own gravity. This collapse creates a singularity, a point of infinite density at the center of the black hole. The processes involved in their formation include the gravitational collapse of the star's core, followed by the expulsion of outer layers in a supernova explosion. The remaining core then collapses further to form a black hole.
Dark matter is a mysterious substance that makes up a large portion of the universe's mass, but its exact nature is still unknown. While some theories suggest that dark matter could potentially be made up of black holes, this idea is not widely accepted among scientists. More research and evidence are needed to determine the true nature of dark matter.

The existence of primordial black holes could challenge current theories about the formation and evolution of the universe. They could provide insights into dark matter, the early universe, and the nature of gravity. Further research is needed to fully understand their implications.
Black holes (in the astronomical sense) have never been made in the laboratory.
Stephen Hawking was a theoretical physicist known for his work in the fields of cosmology, quantum mechanics, and black holes. He made significant contributions to our understanding of the origins of the universe, particularly with his work on the theory of black holes and Hawking radiation.

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.
Professor Stephen Hawking proposed that black holes interact thermodynamically with the universe in specific ways; for example that radiation could be generated by quantum effects near the event horizon (Hawking radiation) and thus carry mass away from it, per Einstein's proof of the equivalency of mass and energy; thus a black hole's mass could decrease over time and eventually it could "evaporate" entirely.

If you know,there lies a black hole at the center of every galaxy,so the number of galaxies in the universe,same number of black holes.But there could be trillions of galaxies,witch also means trillions of black holes. There maybe a black hole in the center of every galaxy but there are also called stellar black holes. Stellar black holes can be find ANYWHERE in space.So it is not only the ammount of galaxies. There is a unknown answer to this question.There might be billions of black holes. Scientists do not know yet. Since we can only see about 13 billion lightyearsof the Universe from this position, its impossible to know even an estimated number of anything in the universe. That's including black holes.
