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.
As many people that looked up this question :)
Black holes were discovered in 1972 by Tom Bolton. When Tom Bolton discovered this, the black hole was 8,200 light years away from the Earth (1 light year is 6 trillion miles).
Stephen Hawking discovered many different things.
The milky way contains about a dozen black holes in the milky way.
The concept of a black hole was first discovered mathematically in 1916 through the equations of Einstein's general relativity. Using mathematics scientists were able to figure out many of the properties and behaviors of black holes before the end of the 1960s. The first direct psychical evidence of a black hole was not found until the late 1970s.

Yes, many galaxies have supermassive black holes at their centers.
Whoever said this seems to think that there is not enough direct evidence for black holes. However, I understand there is enough evidence to believe that black holes actually exist - including the observation of many, many objects that can only be black holes.
Yes, black holes are known and regarded by many scientists, astronomers, and physicists.

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.

Not really "a" black hole - many black holes. It is currently believed that all, or most, galaxies have a huge black hole at its center. Any galaxy should also have lots of smaller black holes - so-called "stellar" black holes, because they have approximately the mass of a star (larger stars can become black holes).
Not all galaxies have black holes in their centers, but many large galaxies, including our own Milky Way, are believed to have supermassive black holes at their centers.
Not all galaxies have black holes. While many galaxies, including our own Milky Way, have supermassive black holes at their centers, there are also galaxies that do not have black holes. The presence of a black hole in a galaxy depends on various factors such as the size and age of the galaxy.
