Black Holes

The galaxy NGC 3842, around 320m light years from Earth in the constellation of Leo, has a black hole at its centre with a mass of around 9.7billion suns. An even bigger black hole with a mass of around 21billion suns exists at the heart of galaxy NGC 4889, the brightest galaxy in the Coma cluster, around 336m light years from Earth.

Scientists study distant galaxies to understand the formation, evolution, and properties of galaxies over time. By observing galaxies that are far away, they can explore the universe at different epochs and gain insights into how galaxies have changed and evolved since the early universe. Studying distant galaxies also helps scientists refine theories about the laws of physics and the nature of the universe as a whole.

There is no definite boundary for matter not being pulled toward a black hole. At large distances the effects of a black hole's gravity are not different from that of a different object of the same mass. How far out a black hole's gravity is dominant depends on that black hole's mass and its proximity to other massive objects.

The area surrounding a black hole is called the event horizon. Any object that gets caught in the event horizon will never return. All black holes have an event horizon. Black holes that have a charge and a spin, will generally have an inner horizon (coinciding to the outer horizon, the event horizon). At the inner horizon, matter is infinitely compressed and then sucked into the singularity. Along with black holes are white holes (otherwise known as "anti-black holes"). White holes are the exact opposite of a black hole, instead of sucking and trapping matter to where it is lost from the universe, white holes spew out matter and return it to the universe. Most scientists agree that white holes don't exist in our universe because they are very unstable. If the white hole was able to exist at all, it would last for only a couple of milliseconds before evaporating. The main thing between a black hole and a white hole is that a white hole is the black hole in the future. Inside the inner horizon, something bizarre happens. Matter enters one of two very narrow laser like beams. One beam goes against the black hole's spin and has positive energy and moves forward in time, but here's the real brainteaser, matter that enters the beam moving WITH the black hole's spin moves backwards in time and has negative energy. These two beams are shot out of the black hole at either end at nearly the speed of light. The black hole is basically a giant particle accelerator. Now I was correct. When the black hole shoots out the two beams, it becomes the white hole from the distant future. The two are the same. Now I know you just wanted the answer to the event horizon, but I just wanted to share a little more knowledge.

Light that passes near a black hole but does not cross the event horizon is bent toward it in what is called gravitational lensing. The closer the light passes to the black hole, the more it is bent. For someone with an up-close view, this lensing would result in a highly distorted image of whatever is behind the black hole. Photons that cross the event horizon are lost inside of it forever, and their energy is added to the mass of the black hole.

a black hole won't explode until the universe is almost dead. black holes will be the last thing in the universe just roving aroud searching for something to feed off of then once all energy is gone they die but they go out with a huge explosion.

Black holes destroy planets or stars by exerting a powerful gravitational pull, which can rip them apart through a process known as spaghettification. Additionally, the intense tidal forces near a black hole can also strip away the outer layers of a star or planet, ultimately consuming them.

Jaffy Lewis is a character from the book "Holes" by Louis Sachar. He is a fellow camper at Camp Green Lake with the protagonist, Stanley Yelnats. Jaffy is known for being lazy and often relies on others to do his work for him.

No, the singularity itself does not cause stars to explode. Stars can explode in a powerful event called a supernova when they run out of nuclear fuel and can no longer support their own gravity. The singularity is a point of infinite density at the center of a black hole where the laws of physics as we know them break down.

"after a supernova" is the adverb phrase in the sentence.

Black holes do not destroy things in the traditional sense of actively targeting and destroying objects. However, anything that crosses the event horizon of a black hole – known as the point of no return – will be unable to escape its gravitational pull, effectively being consumed by the black hole. This process, known as spaghettification, involves the stretching and tearing apart of matter due to the extreme gravitational forces near a black hole.

There aren't dogs or cats there either. Neither of those things is a star.

A nova isn't a type of star, it's an event happening to a star (kind of like a solar flare or a sunspot, except on a much bigger scale).

Depending on the intent of the question, the consistency of a black hole might refer to one of several separate considerations. Perhaps most obviously, what a black hole 'consists of' might refer to its general anatomy; it would be described as a region in which the curvature of timespace becomes infinite owing to the presence of matter whose radius is smaller than its Schwarzschild radius, and from which the escape velocity is faster than the speed of light (hence, light doesn't escape). The nature of matter inside the black hole, while not directly observable, is believed to be concentrated at its center in a region called a singularity, which contains matter whose density is infinite (i.e., it exhibits mass but zero volume). As such, the type or kind of matter in this singularity is not yet adequately described by our physics and it sometimes referred to as 'exotic.' Since escape velocity from a specified distance from a mass decreases with increased distance from this singularity, there is a notional boundary where the escape velocity is c (the speed of light), a spherical or spheroidal region called the event horizon, which, if matter passes inward, it's a one-way trip - it would be unable to exit.

If the intent of the question relates to a physical property of matter other than mass, charge, or spin, (for example, the idea of consistency one might associate with texture) then one would have to refer to the 'no hair theorem', which states that properties other than these aren't really applicable, and in that sense, all black holes are similar. Note that properties such as size or overall density can be derived from mass. Outside the black hole other effects are often apparent, like the presence of an accretion disk of superheated infalling matter, or relativistic jets at the poles.

If the intent of the question refers to how often a black hole changes (i.e., is it consistent and unchanging in time) then one need only recognize that it will continue to exist so long as at least some matter is falling into it from the surrounding space. Fairly recent studies suggest that black holes may interact with the universe in such a way as to lose very small amounts of mass over time (see Hawking radiation). If a black hole were to be isolated such that no matter would fall in over an extremely long interval, it is conceivable that through this mechanism they would "evaporate" entirely and thus eventually cease to exist.

No.

A black hole intakes matter.

After it is broken down by gravity.

Then it releases it as particles (Neutrinos for example)

There is not another universe within a black hole. Nor do stars or matter stay within the black hole.

Of course all of this is theory with some really fun math attached to it.

This is a reference to the misery and human suffering associated with the Black Hole of Calcutta.

This is referring to an event that may have occurred at the Black Hole of Calcutta, which was the name of the converted guard room/holding cell of Fort William in Calcutta, India. After the fort was taken by the Naweb from the British on June 19, 1756, the Naweb held all of the British prisoners of war in this tiny room, during which time most of the prisoners were crushed to death or suffocated. This event's accuracy is dubious, and some believe that it's a tall-tale invented for British propaganda purposes. My source is linked below.

In a black hole, all matter and energy that crosses the event horizon gets sucked in due to the immense gravitational pull. This includes light, particles, and even information, which becomes trapped within the black hole's singularity at the center.

Astronomers studying black holes would typically need to study physics, particularly in the areas of general relativity, quantum mechanics, and thermodynamics, to understand the nature and behavior of black holes. They may also need to study astrophysics, cosmology, and computational modeling to analyze observational data and simulate black hole interactions with their surroundings.

Yes, a mid-sized star can eventually become a white dwarf or a black dwarf. After exhausting its nuclear fuel, the star sheds its outer layers to form a planetary nebula, leaving behind a white dwarf. Over trillions of years, a white dwarf may cool and fade into a black dwarf, although this process would take longer than the current age of the universe.

The black thing in the center of the eye is called the pupil. It is an opening that allows light to enter the eye and reach the retina, which is responsible for processing visual information. The pupil adjusts in size to regulate the amount of light entering the eye.

Black holes can be detected using a variety of methods. While the black hole itself does not emit any radiation (or any other form of energy), high-energy radiation can still be emitted by matter that is being pulled into it. For example, if a black hole begins to consume a star that has ventured too close, the star will begin to emit x-rays, gamma rays, and/or particle jets as it is pulled apart. When a black hole is "feeding" it can be anything but black: the heat and energy emitted by the ill-fated star (or planet or another black hole or anything else for that matter) can make the location of the black hole to be quite bright.

Black holes can also be detected by spotting how they affect their nearby neighbours. They can cause "ripples" in space time, and as these gravitational waves move through space, their affect on objects can be detected and measured.

No, it is not a black hole because if it is a black hole there would be no animals or human beings on Earth.

Dr. Ben Clennell, of Leeds University, England, is not the first to make note of the possibility of methane hydrates as a source for causing ships to disappear, he has become identified with the theory which, on September 21, 1998, at the Festival of Earth Sciences at Cardiff, Wales, he proposed methane hydrates as the future of energy.

As a part of his elaborate dissertation he claimed that methane locked below the sea sediments in the Bermuda Triangle can explain the mysterious disappearances. He told how subterranean landslides can unlock the vast beds of methane hydrate. This would be disastrous, he told the audience, because large amounts of methane would reduce the density of the water. "This would make any ship floating above sink like a rock." He went on to explain how the highly combustible gas could also ignite aircraft engines and blow them to pieces.

Despite this, there has never been any evidence of why ships disappear in the Bermuda Triangle.

according to the Percy Jackson series the Bermuda triangle is known as the sea of monsters

There is no black hole in the Pacific Ocean. Black holes are astronomical phenomena that occur in outer space and cannot form within Earth's oceans.
