A black hole of the mass of the Sun will take somewhere around 1067 years to evaporate. A supermassive black hole can take 10100 years or more to evaporate. If you write it out, this latter is a 1, followed by 100 zeros; in any case, much longer than the current age of the Universe.
The supermassive black hole in the center of our Milky Way is at a distance of about 28,000 light-years. The nearest known stellar black hole is at a distance of about 3000 light-years.
For all scientific reasons, no astronaut had went inside a black hole. It would take many earth years to visit the black hole, so reaching a black hole is impossible.
Nobody has ever visited a black hole. The nearest known black hole is many light years away. Much to far away for us to reach it.
The famously first-observed black hole in Cygnus known as Cygnus X-1 is about 6,070 light years distant.
There is not "a" black hole, but many of them. The nearest known black hole is at a distance of several thousand light-years, but it is likely that there are others closer by: only black holes that are very near of a partner (in a binary system) are easily found.There is not "a" black hole, but many of them.

There are many black holes in the universe .Scientists believe that there might be a black hole in the centre of our Milky Way galaxy which is about 25,000 light years from earth, and that that is why it rotates about its axis.
Since the nearest black hole is many light years away from Earth, it's impossible for a scientist to physically travel to a black hole to study it. Instead, they have to make do with observing the effects of black holes from Earth.
Don't know which black hole.
None. No rocket has ever gone anywhere near a black hole (seeing as how the nearest one is 1600 light years away).
The Black Hole of Auschwitz has 187 pages.
Something similar to a black hole but with an exit would have to be a worm hole. worm holes are only science fiction (because they have not been proven to exist) although many people believe when entered they will transport you through many light years of space.
A miniature black hole is what forms when atoms smash at a rate to form a mini black hole, gobbling many protons and neurons and other extremely tiny things. Don't worry, they still don't "eat" very much. They also don't last very long.
