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.

How many properties of the matter inside a black hole can be measured from outside the black hole?

Only three properties can be measured from outside a black hole: mass, electric charge, and angular momentum (spin). These properties determine the black hole's gravitational effects on its surroundings and are observable through the gravitational pull they exert on nearby objects or through the radiation emitted by the black hole.


How many Planets in black hole?

There is simply no way of knowing this. Once matter is consumed into a black hole, it is converted into gravitational energy; a black hole's contents cannot be dissected and catalogued. However, according to an idea called the holographic principle, it may be possible for all the information contained within a black hole is encoded on its surface. If this proves to be true, then it might be possible to determine everything that has been sucked into the black hole.


Does M65 galaxy have a black hole?

Yes, the M65 galaxy is thought to have a supermassive black hole at its center, like many other large galaxies. This black hole likely plays a crucial role in shaping the galaxy's properties and evolution.


Did scientist send unmanned spaceships into a black hole to gather information?

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.


Can a black hole expand?

As a black hole becomes more massive, its event horizon expands. No one knows what happens inside the event horizon. Many have advanced different speculations. We know it retains mass and angular momentum.

Is the universe inside a black hole?

No, the universe is not inside a black hole. Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape from them. The universe is much larger and contains many galaxies, stars, and planets, including black holes.


How many stars did this black hole eat?

Don't know which black hole.


What elements and compounds are there inside a black hole?

For large black holes, it's reasonable to expect that outside the singularity it's the same elements and compounds we have in the universe generally; however, it's impossible to actually know, because "inside" a black hole (within the event horizon) is in many respects not actually in the same universe that we are.


Does every galaxy contain a black hole?

No, not every galaxy contains a black hole. While many galaxies do have a supermassive black hole at their center, there are also galaxies that do not have a black hole.

How many atoms are there in a black hole?

Basically none. No atom will survive the forces in a black hole. (However, all the mass that falls into the black hole will still be there.)


What will the black hole do to your solar syatem?

Nothing, unless a black hole comes very near to us. By the way, you shouldn't say "the" black hole, unless you make it clear which black hole you mean. There are many black holes.

Is black hole real and if it is how do you get to the site?

If you mean a black hole in astrology, then there is no certain answer. Black holes are basically scientific theories. As for the second part of your question, even if we could travel who-knows-how-many lighyears away from Earth to reach a black hole in a spaceship, astronauts would die instantly. Black holes were once GIANT stars that exploded and began to suck everything around them, into them. Even light. No one knows what happens to the matter within a black hole because anything they send towards one would be crushed by the incredible amount of gravity. So to summarize, they might be real but they aren't on or near Earth.


Who is the first man in the black hole?

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.
