Is a black hole a thing or an empty space.?

Question

It's down to 2 and 4. Any other.?

Answer 1

a thing

Answer 2

A black hole is a thing, known to astronomers as an object ! It just seems empty because of it's color .

I looked up some info here at my observatory for you ..

A black hole is what remains when a massive star dies.
History
The concept of an object from which light could not escape (e.g., black hole) was originally proposed by Pierre Simon Laplace in 1795. Using Newton's Theory of Gravity, Laplace calculated that if an object were compressed into a small enough radius, then the escape velocity of that object would be faster than the speed of light.

If you learned how stars work, then you know that a star is a huge, amazing fusion reactor. Because stars are so massive and made out of gas, there is an intense gravitational field that is always trying to collapse the star. The fusion reactions happening in the core are like a giant fusion bomb that is trying to explode the star. The balance between the gravitational forces and the explosive forces is what defines the size of the star.

As the star dies, the nuclear fusion reactions stop because the fuel for these reactions gets burned up. At the same time, the star's gravity pulls material inward and compresses the core. As the core compresses, it heats up and eventually creates a supernova explosion in which the material and radiation blasts out into space. What remains is the highly compressed, and extremely massive,
core. The core's gravity is so strong that even light cannot escape.

This object is now a black hole and literally disappears from view. Because the core's gravity is so strong, the core sinks through the fabric of space-time, creating a hole in space-time -- this is why the object is called a black hole.

Answer 3

No. A black hole is a extreme concentrated mass that has so much gravitational pull nothing could escape it in theory. Black holes were originally called "Frozen Stars" and there is no empty space at all in them. There are also "White holes" and "worm holes, crazy stuff. And I hate these people that give long answers, to paste an answer is to not think about your answer!

Answer 4

It starts out as a star untill the fusion process in the core of the star makes materials too dense for fusion to continue. anyways, the star dies out and the core is left. it's gravitational field attracts more and more matter and continues getting denser. It compacts into an extremely small amount of space. Black holes have such a strong gravitational field that not even light can get away from them. You can find a lot more information on this on the internet.

Answer 5

Its an object with a strong gravitational field. Empty space would be a vacuum, which behaves much differently.

Answer 6

definitely its a thing it is the result of an exploding star 1000 times bigger than our sun this little thing is so dense that its gravitational pull is so great that nothing can escape from it not even light

Answer 7

A thing used as a portal to warp

Answer 8

A burned out sun probably

Answer 9

Black Holes are created by expired stars in the universe. You see A black hole is an object predicted by general relativity with a gravitational field so strong that nothing can escape it, not even light. Under the description provided by general relativity, as an object moves closer to a black hole, the energy required for it to escape continues to increase until it becomes infinite at the event horizon, the surface beyond which the escape is impossible. Inside the event horizon, the geometry of spacetime is distorted in a way that moving closer to the central singularity is inevitable no matter how the infalling object moves.

The existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei. It has also been hypothesised that black holes radiate energy due to quantum mechanical effects known as "Hawking" radiation. Stephen Hawking Made some amazing discoverys about black holes! General relativity (as well as most other metric theories of gravity) not only says that black holes can exist, but in fact predicts that they will be formed in nature whenever a sufficient amount of mass gets packed in a given region of space, through a process called gravitational collapse. For example, if you compressed the Sun to a radius of three kilometers, about four millionths of its present size, it would become a black hole. As the mass inside the given region of space increases, its gravity becomes stronger — or, in the language of relativity, the space around it becomes increasingly deformed. Eventually gravity gets so strong that nothing can escape; an event horizon is formed, and matter and energy must inevitably collapse to a density beyond the limits of known physics.

A quantitative analysis of this idea led to the prediction that a stellar remnant above about three to five times the mass of the Sun (the Tolman-Oppenheimer-Volkoff limit) would be unable to support itself as a neutron star via degeneracy pressure, and would inevitably collapse into a black hole. Stellar remnants with this mass are expected to be produced immediately at the end of the lives of stars that are more than 25 to 50 times the mass of the Sun, or by accretion of matter onto an existing neutron star.

Stellar collapse will generate black holes containing at least three solar masses. Black holes smaller than this limit can only be created if their matter is subjected to sufficient pressure from some source other than self-gravitation. The enormous pressures needed for this are thought to have existed in the very early stages of the universe, possibly creating primordial black holes which could have masses smaller than that of the Sun.

Supermassive black holes are believed to exist in the center of most galaxies, including our own Milky Way. This type of black hole contains millions to billions of solar masses, and there are several models of how they might have been formed. The first is via gravitational collapse of a dense cluster of stars. A second is by large amounts of mass accreting onto a "seed" black hole of stellar mass. A third is by repeated fusion of smaller black holes.

Intermediate-mass black holes have a mass between that of stellar and supermassive black holes, typically in the range of thousands of solar masses. Intermediate-mass black holes have been proposed as a possible power source for ultra-luminous X ray sources, and in 2004 detection was claimed of an intermediate-mass black hole orbiting the Sagittarius A* supermassive black hole candidate at the core of the Milky Way galaxy. This detection is disputed.

Certain models of unification of the four fundamental forces allow the formation of micro black holes under laboratory conditions. These postulate that the energy at which gravity is unified with the other forces is comparable to the energy at which the other three are unified, as opposed to being the Planck energy (which is much higher). This would allow production of extremely short-lived black holes in terrestrial particle accelerators. No conclusive evidence of this type of black hole production has been presented, though even a negative result improves constraints on compactification of extra dimensions from string theory or other models of physics....

Answer 10

It is an object.
