Black Holes And The Black Hole

Furthermore existence that black holes exist comes from the observations of astronomers of bursts of energy which are detected and then lost. An event horizon is an area of space around a black hole for which nothing can escape, once an object or any matter crosses this event horizon the gravity of the black hole will be too strong for it to escape. As a cloud of gas swirls and nears a black hole, the gases heat up and will emit x-rays. Astronomers have observed instances of several burts of x-rays being detected and then disappearing at areas where black holes are thought to be found. This may be caused by the gases emitting x-rays and then crossing the event horizon and disappearing forever. The observations of these bursts of energy are useful for astronomers in finding black holes.

Discovered in 1916 by Albert Einstein, a black hole is an area of space-time showing very strong effects, that nothing can escape from the black hole. Space-time is the belief that there is no time in space, so there is no aging or time whatsoever. There are three different types of black holes. Stellar-mass, supermassive, and intermediate. All three are very strong, but the supermassive is currently the strongest reported. Not all black holes are large, but extremely powerful. The supermassive black holes are the biggest type of black hole and most of the time are found in the center of massive galaxies. Stellar-mass black holes are formed by a star collapsing. Intermediate black holes are stronger than stellar-mass black holes, but weaker than supermassive. Supermassive is the least common black hole there is.

Black holes should probably not be called black holes. In fact, black holes are anything but empty space. Black holes are a great amount of matter packed and squeezed into a very small area. The result of this amount of matter squeezed into a small area results in a gravitational field so strong that nothing, not even light, can escape.

A black hole is a region in space where the pulling force of gravity that is so strong that the region cannot escape. This compression can take place at the end of its stars life. Some black holes are a result of dying stars. How every space telescopes with special instruments can help find black holes. They can observe the behavior of material and stars that are very close to black holes. Black holes can come in a rage of signs, but there are three main types of black holes. The black holes mass and size determins what kind it is. The smallest ones are known as primordial black holes. Scientists believe this type of black hole can be up to 20 times greater than the mass of the sun and fit into a ball of about 10 miles. The largest black holes are called supermassive. Supermassive black holes are at the center of the milky way galaxy is called sagittarius. A black holes gravity can be as strong to pull off the outer layer gass of the star and grow a disk. The

​Black holes are associated with the destruction or dying of relatively large stars. Black holes do not happen every time such stars are collapsed. The collapsing of stars mostly result in

Most commonly spotted is the large GRB with its process beginning with a large spinning star reaching its destruction. As the star begins to collapse within itself the thick layer of dust and gas around it begins to suck in. This process is known as Hypernovea. Once this core has been compressed into a rapid spinning black hole, debris surrounding becomes energized and produces a large burst of gamma. After the burst the gamma disappears, leaving only electromagnetic waves though afterglows can be recorded anywhere from minutes to weeks after the initial burst. It has been recorded that the amount of energy that they put out reaches 94 billion electron volts, approximately 34 billion times the energy of visible

Without knowing the existence of black holes, we would still be stuck with many unanswered questions concerning physics. The most important one would deal with the correctness of Einstein’s general relativity. When studying cosmology, various equations are used in order to explain the different phenomena that it contains, which are derived from general relativity. With this theory confirmed, all calculations appear more certain and confident. These objects are fairly important as they are one of the least understood by humans because they depict laws of physics that appear completely different from elsewhere in the universe, but, with study, can be more understood. Being completely invisible, it becomes very difficult to observe and study them. However, astronomers continue to develop different methods to do so. The question that remains is: What exactly is a black hole? How do they work and abide to the laws of physics? Simple answer, black holes are regions in space containing gravitational fields so strong that even light cannot escape them. As a result, they absorb anything that comes close and becomes trapped by its grip. Black holes come in various forms and sizes, which work differently depending on their properties. These properties, such as mass, charge and angular momentum, help in defining black holes and it is using this that it is possible to derive the math to understand them.

How are black holes formed? Black holes are said to be made from stars that run out of core energy or the fuel that is in the middle. Once the star runs out of energy it caves on itself and then explodes. The explosion of the star has a scientific term; this term is called supernova. This was discovered the 1604 when Johannes Kepler saw a three colors: blue, green, and red explode in the sky. Scientists think that black holes are created after a supernova. If you get scared easily then you have to remembered

By the time the black hole reached the asteroid belt between Mars and Jupiter, things would look bleak for us. The intense gravitational pull of the black hole would have torn our planet asunder, causing devastating earthquakes and super volcanoes the likes of which humanity has never witnessed before. Upon reaching Earth’s orbit our planet is all but doomed, reduced to a smoldering uninhabitable magma-laden rock, with Mercury and Venus soon following suit. “I found this information on http://www.spaceanswers.com/solar-system/what-would-happen-if-a-black-hole-entered-our-solar-system/ I thought it was extremely interesting. A question I would like to spend more time on in class is how a black hole can be smaller than the sun, but its mass be

Another method in physics on how to time travel is through black holes. A black hole has been discovered by Einstein's theory of general relativity, which showed that when a star dies, it leaves behind a small, dense remnant core. If the core’s mass is more than the sun, the force of gravity overwhelms all other forces in which it transforms into a black hole. Scientists have said that black holes can destroy anything that goes in it and it could be hard to get out of a black hole, once something went in it. In an interview by physicist Lior Burko, he states, “One possibility is that black holes may allow us to travel to very remote places in the universe, or another universe entirely,” (Kahney, “Black Holes and Space Time”). Black holes may have evidence that there are different kinds of parallel universe. Even though it is still unclear what black holes can do as in destroying everything that it goes in or if it leads someone to time travel into another parallel universe. Scientist are trying to create a black hole, here on earth, to see what blacks can do as in sending information to another universe.

Have you ever taken the time to reflect and glaze upon the night sky, conjecturing and dreaming of what lies beyond our planet? Our universe also known as the Milky Way Galaxy is very miscellaneous and unique. With many marvelous wonders, the Milky Way Galaxy holds about mysterious belongings that are very challenging for human minds to understand due to the many complications that arise when we try to examine and explore the principles of space. One of the universe biggest mysteries is that of the ever indescribable, black hole. By definition, a black hole is a “celestial body so dense that light cannot escape its gravitational pull. It is formed when a star gravity causes it to

The American scientist John Wheeler coined the phrase “black hole” in 1969 to describe a massively compact star with such a strong gravitational field that light cannot escape. When a star’s central reserve of hydrogen is depleted, the star begins to die. Gravity causes the center to contract to higher and higher temperatures, while the outer regions swell up, and the star becomes a red giant. The star then evolves into a white dwarf, where most of its matter is compressed into a sphere roughly the size of Earth. Some stars continue to evolve, and their centers contract to even higher densities and temperatures until their nuclear reserves are exhausted and only their gravitational energy remain. The core then rushes

This is one way that matter could escape the black hole. Huge jets of gas sometimes come out from either ends of the hole, or gas will spin around the hole, called an accretion disk.

The common misconception of black holes is that they are ‘a hole’ in space, but the fact is, they are a dense orb of matter that continuously grows and consumes. Popular believe is that a black hole is a gateway through time and space but that is not the case. All someone would find at the center of a black hole would be a dense orb a matter called the singularity, or core (Freudenrich). Black holes do in a way distort time and space because of their immense mass yet one would die and be burnt to a crisp before even coming close to reaching the highly dense core. If watched from the earth, it would take an infinite amount of time to be consumed by and become a part of a black hole, but

A black hole is one of the most fantastic things ever predicted by modern science. It is a place where gravity is so strong that nothing --not even light-- can escape. It is a place where gravity is so strong that a hole has been rent in the very fabric of space and time. Surrounding this yawning chasm is a 'horizon' in the geometry of space where time itself stands still. And inside this hole, beyond this horizon, the directions of space and time are interchanged.
