Blackholes Research Paper

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.

This paper will introduce you to the incredible topic which is black holes. A black hole is a region of space time exhibiting such strong gravitational effects that nothing can escape from inside it. (NASA) No human has ever entered a black hole and there is still a large mystery about them; we have very little idea of where the matter that enters them goes. A black hole cannot be looked into either, as it sucks all the light into the middle of it. Space programs use special satellites with certain features that allow them to see these black holes. A black hole can be big or small, sometimes forming when a star is dying. Some scientists speculate that there can be black holes just 1 centimeter large. There are multiple types of

Throughout the modern era of astronomy, a single type of celestial object has puzzled astronomers more than any other. Black holes, whose existence was only verified in the early 1990’s, have fascinated scientists ever since Einstein first proposed the theoretical concept in the 1930’s. A black hole is an object so tiny, but also so dense, that it has the power to pull planets, stars, and even light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of space and time; however, many of these recent discoveries lead to more unanswered questions. Nevertheless, the basic life cycle of a black hole is now understood in ways thought to be impossible only twenty years

Black holes are some of unusual and most interesting objects found in outer space. The first thing I learned, black holes are objects of the greatest density due to the strong gravity because mater has been squeezed into a tiny space. With the black holes relationships with mass and gravity, they have an extremely powerful gravitational force that even light cannot escape from their grasp if it comes near enough. Second thing I learned is about the inner region of a black hole, where its mass lies, is known as its singularity, the single pint in space-time where the mass of the black hole is concentrated. The third thing I learned that I found the most fascinating is if the earth ever falls into a black hole, one of the effect that will happen is “spaghettification,” which means if objects come too close to a black hole, it will stretch out, just like a spaghetti. This effect is brought about by a gravitational gradient across the object or a body. For example, if earth comes too close to a black hole, the nearest part of the planet will be pulled by an enormous gravitational pull, while leaving the farthest part with a small gravitational force. The fourth thing I learned is that the new hypothesis suggests that anything that touches a black hole will become an

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.

Black holes are strange because we can not see them because they have such a strong gravitational pull light can 't escape from. They can rip anything apart. Black Holes form when a star dies and collapses in on itself. They are usually relatively small and really dense. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. In the milky way their are a few hundred million black holes. In recent years, NASA instruments have painted a new picture of these strange objects that are, too many, the most fascinating objects in space.

There is proof that black holes do eventually disappear. But for most black holes this time for them to disappear is unimaginably long. But if there were to ever be a black hole the size of a cruise ship it would evaporate in the time of seconds. Because the flash of light that is created from all the light that is on a subatomic level being created or destroyed. This is irrelevant to any black holes in the universe because there is no known black holes the size of a cruise ship and the temperature that this light gives of is almost zero degrees and the energy loss is

Miniature Black Holes: It is said that this type was formed during the Big Bang, but there was no evidence to prove this within the evolution of the universe. The mass of these black holes is much smaller than the mass of the sun, and they have formed through the external pressure during the Big Bang that compressed the mass to create the singularity. (Mathew,2012)

Black holes are born by using many of the star's energy so it can evolve.Black holes you can rarely find them in space they are, so common in space that they are hard to find and since space is really dark than black holes are going to be even harder to find. The way black holes form is by them beginning of as a star and then using all the other stars energy to start evolving and growing bigger. And the cycle is pretty complicated because it will take days to gather enough energy from all the other stars it may even take years for the black hole too become an adult. When the black hole takes up all the energy from the star the star breaks up into a million pieces maybe chances of creating another star. Black holes are mostly stars but bigger and filled with energy from millions of

Black holes are born from the aftermath of a supernova. But supernovas can also turn into neutron stars if there is not enough mass to make a black hole because a neutron star just does not have the amount of matter to make a black hole it still has an extremely high gravitational pull and magnetic field. A black hole has such a high gravitational pull that light can not even escape. The reason for a black hole’s extremely high gravitational pull is that it has a great extent of mass packed into a tiny space that it makes a super gravitational pull (Dunbar, Brian). So because of the super high gravity black holes are extremely dangerous and hard to examine.

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

Scientists aren't certain of how supermassive black holes are created. It could be because hundreds or thousands of tiny black holes merge together, large gas clouds could also be responsible, collapsing together. A third option is a group of stars all collapsing together. Once supermassive black holes have formed, they gather dust and gas from around them, causing them to grow even bigger.

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.

Main sequence stars like our own sun enduring in a state of nuclear fusion during which they will produce energy for billions of years by replacing hydrogen to helium. Stars change over billions of years. When their main sequence phase ends they pass through other states of existence according to their size and other characteristics. The larger a star's mass, the shorter its lifespan is. As stars move toward the end of their lives, much of their hydrogen will be converted to helium. Helium sinks to the star's core and raises the star's temperature—causing its outer shell to expand. These large, puffy stars are known as Red Giants. The red giant phase is actually a prelude to a star shedding its outer layers and becoming a small, dense body called a White Dwarf. White dwarfs cool down for billions and billions of years, until they finally go dark and produce no energy at all. Once this happens, scientists have yet to observe, such stars become known as Black Dwarfs. A few stars avoid this evolutionary path and instead go out with a bang, exploding as Supernovae. These violent explosions leave behind a small core that will then turn into something called a Neutron Star or even, if the remainder is large enough, it is then turned into something called a Black Hole.
