Essay on Black Holes

The existence of black holes was first theorized by John Mitchell in 1783. Mitchell accepted Newton’s laws of gravity and suggested that light escaping from the surface of a star would have its speed reduced due to the gravitation pull of the star, and therefore if a star’s gravitation pull was strong enough even light would not be able to escape.[1] Using the approximate speed of light he reasoned that if an object was approximately 500 times the mass of the sun light would not be able

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 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

As stated above, in 1915, Albert Einstein’s general relativity theory proved that black holes do exist. This discovery opened the doors for astronomers to do further research. Scientists realized that black holes form from the death of supergiants. Also, scientists have discovered that there are three to four different types of black holes that can either rotate or stay stationary. Additionally, astronomers made discoveries from how black holes strengthen their gravity to their ability to pull light in. As scientists continue to research space, more facts of these mysterious black holes will be

When many people think of black holes they think of a giant portal in space eating galaxies and moving on to the next as most commonly seen in pop culture shows such as Star Trek. The reality is however that while we spend a lot of time studying them we know very little about Black holes. What we do know is that there are two types of black holes based on their relative size, there are Stellar black holes and Supermassive black holes. Stellar black holes are only a few times larger than our sun while Supermassive black holes are about a billion times larger than our sun. Both types of black hole are formed when a star implodes and there is nothing left to burn. This can be seen by observing how light and matter cooperate with the event horizon, a second way to detect black holes is through X-Rays by noticing when stars rotate around a gap in space. By studying the speed of stars orbiting, and calculating their paths it is possible to determine the mass and size of a black hole. Using these pieces of evidence we can determine that stellar black holes do exist and

Yesterday, NASA released news that will help us understand the formation of oval galaxies, specifically, the new data answered some old questions about why oval galaxies take so long to form. It turns out that the way a black hole controls the proto-matter of a baby galaxy actually regulates star birth as the galaxy takes shape around it.

It is believed that every galaxy has a super-massive black hole in its centre! A super-massive black hole would be millions of solar masses, which would be a million million times the mass of the Earth! Imagine that. The sun won’t ever turn into black hole because its mass is too small. However let’s assume that it did, the black holes diameter would be around 2 miles. Would we start moving towards it until we got sucked in? No because the black hole would have the same mass as the sun so it would have the same gravitational force on us as the sun so we would continue to orbit the black hole as usual. So we would carry on living as usual? No because life will as we know it will start dying very quickly because the sun won’t be able to provide us with heat and light so plants would start dying and the whole planet would eventually

But their could be a possible reason to get inside a black hole, but you can also get lost in space knowing you're in the middle of nowhere.Scientist and astronauts are trying to figure out how to get in a black hole without any risks by like simple making the space shuttle more and more advanced each time they go into space. Scientist are still working on finding out the process of black holes dying. Well the process is very simple when a black hole has eventually lost almost all of its energy from the stars it had collected it kind of starts to fade away and the next thing you no the black hole has had exploded and their is just a little star left.so what this whole reaserch essay was for the interesting facts about black holes and hoe they form and also how they live a long time and then they explode and becom a new baby star that then will become another black

Despite modern culture and its influences on the unknown, a black hole is not a well understood concept even by the greatest of minds. Robert Prigo describes a black hole as “…

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

Black holes can be scary to think about, but amazing at the same time. The fact that they can have such a heavy gravitational pull that not even light can escape is fascinating. Luckily we will probaly destroy Earth before a black hole eats it

Black holes had always piqued my interests, from when a small child intently devoured documentary to documentary to when a confused teenager encapsulated herself in a black hole of her own. The science of the black hole transfixed my childhood sense of curiosity, but especially the point that the scientific world labeled the “singularity”, the point at which gravity became infinite.

Black holes are formed when massive stars collapse under the weight of their own gravity (Schoolworkhelper Editorial Team). The nuclear fusion in younger stars creates a constant outward pressure from the core (“Black Hole Images, Facts and Information”). This balances the pull from the gasses in orbit around the core, keeping the star stable (Schoolworkhelper Editorial Team). Once a star’s life is nearing the end, and its gasses have almost all been used up in the nuclear reactions, the star will collapse inward from the gravitational pull without the outward push of the reactions (Schoolworkhelper Editorial Team). This happens to stars of at least six to eight times the mass of our sun (Schoolworkhelper Editorial

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
