Black Holes

Black holes are some of the most interesting objects in the entire Universe.

What Is a Black Hole?

A black hole is a place in the space where the gravitational pull is so much that even light rays can not escape. This strong gravitational pull is because of the matter that has been squeezed into a tiny space. This thing can happen when a star is dying. Black holes can not be seen by us,because no light ray can get out from it. They are like invisible.We can only study the black holes with the help of special space telescopes.These special tools can see how differently the stars behave when they are very close to the black holes.

Black holes can be big or small in size.

Types of the Black Holes.

Supermassive black …show more content…
These black holes have masses that are more than 1 million suns together.Every large galaxy contains a supermassive black hole at its center.
The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It possesses a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths.

According to the scientists black holes can be also as small as just one atom. These black holes are very tiny but have the mass equivalent to a large mountain.
Small black holes populate the universe, but their cousins, supermassive black holes, dominate. Supermassive black holes are millions of times as massive as the sun, but have a radius similar to that of Earth's closest star. Such black holes are thought to lie at the center of pretty much every galaxy, including the Milky way.

Supermassive black holes may be the result of hundreds or thousands of tiny black holes that merge together. Large gas clouds could also be responsible, collapsing together and rapidly accreting mass. A third option is the collapse of a stellar cluster, a group of stars all falling together.

A neutron star merges with either a white dwarf or another neutron star (also requires a binary system).
Direct formation of a black hole through a core collapse supernova.

MINIATURE BLACK HOLES

It is suggested by theory that miniature black holes might have formed in the early universe,but astronomers do not have any evidence of their existence.Miniature black holes have event horizons as small as the width of an atomic partical and might have been created during the Big Bang.The moment the universe was created.These miniature black holes contain as much matter as Mt. Everest.

How the black holes are detected?

We can not see a black hole because strong gravity pulls all of the light into the middle of the black hole.Scientists see how the strong gravity affects the stars and gas around the black hole.Stars are studied to find , if they are flying around, or orbiting, a black

Black Hole Research Paper

Black holes are one of the greatest mysteries of nature. They are nearly impossible to see with telescopes and other instruments because of their interaction with light. Black holes are so difficult to see that it would be difficult to see one if it were right beside the Earth. This paper will provide an overview of the mystery that is the black hole and provide a discussion of some of the main features of black holes including the causes of black holes, the characteristics of black holes, and an…

Black Hole Research Paper

Black holes are one of the most mysterious and arguably one of the least understood entities in our universe. They are still somewhat of an unknown due to the difficulty astronomers have studying and researching them. It is hard to examine black holes due to their vacuum-like composition and the fact that they cannot be seen by the naked eye. Signals such as radio waves and X-rays can be sent into a black hole, but cannot escape, thus, making further investigations inside almost impossible. Furthermore…

supermassive black hole. This paper explores themes of a supermassive black hole, such as what it is, the birth of a black hole, how did they get so large, quasar, what it leaves behind and the recent findings. A black hole is just an invisible empty space nothing can escape from it, not even light 2. It is black because no light can pass through it and the light is rushing towards the black hole which creates darkness of a black hole. It is empty because any object that passes through the hole the gravitation…

Black Hole Research Paper

Black holes are regions in space, where gravity is so immense that light itself can not escape1. A Black Hole is invisible to the eye, because there is no light inside of a black hole. However, this does not mean that we do not know where they are. Scientists have learned to look at the stars that are around the location of the black hole. Stars will act different when there is a black hole near them. Black holes are formed when the radiation of the star dies out. When the star dies out, it…

We Wear The Mask In Animal Farm

Research Project: We Wear the Mask In this research paper, I will analyze similarities between Animal Farm and three different works- We Wear the Mask, Freedom River, and The Black Hole. The similarities between Animal Farm and We Wear the Mask is that in both works mask were worn to hide their true selves. In We Wear the Mask, the poet states, “We wear the mask that grins and lies, it hides our cheeks and shades our eyes.” In Animal Farm the pigs established laws and helped educate other animals…

Black Holes Lab Report

Introduction- the Evidence and Explanation of Black Holes In order for there to even be a chance of a formation of a stellar black hole(one of the largest types of black holes), a supermassive star must be present. The definition of a supermassive star is a star with a mass more than 50 times the mass of the sun(Dictionary.com), which is approximately 9.9455 x (10 to the power of 31) kilograms, and that's only the minimum needed for a stellar black hole. All stars stay “alive” through the nuclear fusion…

Meanwhile, another team member drew a dot of black washable ink on each piece of paper. Then the sharp instrument was used to make a small hole in the center of both black dots. The holes were filled with the wicks and then placed in the water. While in the beaker, only…

Scientists have agreed when the universe began, however they disagree on how it actually started. This paper will discuss the controversy over how the universe began and the many different theories that have been discovered and rejected and why “the big bang” theory has been the face of the beginning of the universe. Alan Guth described Inflation as an…

Innovative findings by Roger Penrose, another young cosmologist, about stars and the formation of black holes tapped into Stephen’s own fascination about the beginnings of the universe. This captivation led him on a career path that reformed the world’s way of thinking about the universe and black holes. Hawking's extensive research made…
