They have several names. We can call them black holes, supermassive black holes, Singularities. The size of the black holes may vary and can be measured by their pull of gravity and their radiation. (Not that I want to go close for such a task)

How many astronauts went inside the black hole?

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.


What makes a black hole stronger?

A black hole becomes stronger as it increases in mass, which results in greater gravitational pull. When matter falls into a black hole, it adds to its mass, making it "stronger" in terms of its gravitational influence on surrounding objects.


What is more dangerous a black hole or a dark hole?

A black hole is more dangerous than a dark hole. Black holes are regions in space with gravitational forces so strong that not even light can escape, while a dark hole does not have a specific scientific definition and may refer to areas of space with lower light or energy levels.


What is the difference between a black hole's photon sphere and its event horizon?

A black hole's photon sphere is the region around the black hole where photons can orbit in a stable circular path. The event horizon is the boundary beyond which nothing, not even light, can escape the gravitational pull of the black hole. In simpler terms, the photon sphere is where light can circle the black hole before falling in, while the event horizon marks the point of no return.


What is bigbang and black hole?

Big Bang: When space started. Gas, dust and rock particles explode from it and eventually forms celestial bodies. Black Hole: When a star dies or loses its brightness, develops into a dead star or a black hole.

What is the scientific explanation for the phenomenon of a rainbow black hole?

A rainbow black hole is a hypothetical concept that combines the idea of a black hole with the dispersion of light in a rainbow. In scientific terms, a rainbow black hole would be a black hole that somehow bends and scatters light in such a way that it creates a colorful display similar to a rainbow. However, this concept is purely theoretical and has not been observed or proven in reality.


Is a black hole an invertebrate?

A black hole is not a vertebrate or an invertebrate. Those terms apply to animals. A black hole is not an animal, nor is it even alive.

What does a white hole look like and how does it differ from a black hole in terms of appearance and characteristics?

A white hole is a theoretical concept in astrophysics that is the opposite of a black hole. While a black hole is a region in space where gravity is so strong that nothing, not even light, can escape, a white hole is a hypothetical region where matter and light can only escape and nothing can enter. In terms of appearance, a white hole would appear as a bright, glowing object emitting energy and matter, in contrast to the dark, invisible nature of a black hole.


Does every black hole contain a singularity within its core?

Yes, according to current scientific understanding, every black hole is believed to contain a singularity at its core.


What happens at the edge of a black hole?

You are referring to the "event horizon" of a black hole. At this point, nothing, not even light, can escape the gravity of the singularity (or black hole). If you were so unlucky to be there, your body would be stretched from the part that is closest to the black hole. Eventually, your body would be one long string of atoms swirling into the black hole. This is called "spaghettification" and is an actual scientific term.

What is the difference between a black hole and a white hole?

A black hole is a region in space where gravity is so strong that nothing, not even light, can escape from it. A white hole, on the other hand, is a hypothetical region in space where matter and light can only escape from it and nothing can enter. In simple terms, a black hole pulls everything in, while a white hole pushes everything out.


What is the maximum altitude a black hole can be made at?

The question makes no sense. Altitude has nothing at all to do with black hole formation. "Altitude" really only has any significant meaning in terms of Earth and humans, and it is as far as we know absolutely impossible to "make" a black hole at any altitude.

How has the black hole information paradox been solved?

The black hole information paradox has not been definitively solved yet. There are ongoing debates and research in the scientific community to understand how information can be preserved in black holes according to the laws of quantum mechanics.
