As many people that looked up this question :)
Professor Stephen Hawking knows a bunch of facts about black holes. The count would be too difficult to quantify and probably not as interesting as the information itself.
The milky way contains about a dozen black holes in the milky way.
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.
No, there are many black holes in space. They reside throughout the universe and come in different sizes, ranging from stellar-mass black holes to supermassive black holes found at the centers of galaxies.
Black holes are a bit hard to detect, so I am pretty sure that not all black holes in this galaxy are known - and I suspect there is not even a decent estimate. But you can expect there to be several.
No one will know for a long time. We know of some, but not all.
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).
a lot of people for all i know
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.
Obviously u do not know many black people I know tons of black girls with small boobs??
