You Can Escape a Black Hole: Surprising Informative Essay

Understanding Black Holes A Black hole is a theorized celestial body whose surface gravity is so strong that nothing, including light, can escape from within it's surface. Gravity is the key to a black hole's immense power. The black hole's strong gravity keeps captured material from escaping. For example, if Earth were the same mass it is now but had only one-fourth its present radius, the escape velocity of someone standing on its surface would be twice what…

Black Holes Black holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole. Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einstein's general theory of relativity, we have to delve into some results of this theory to understand…

Black holes are one of the many things in the universe that scientists still have a muddy understanding about. However, with the incredible advances of technology, we are able to understand more than what we have in the past. Today, the only way to observe these incredible objects are by looking for radiation from the gas surrounding it. What are they? Black holes are no more than a ³dead star.² A star that is considered ³alive² would be our sun. The sun still produces energy by converting hydrogen…

Black Holes The term black hole was first used in 1969 by the American scientist John Wheeler to describe an object that had such a huge gravitational pull that not even light could escape it, thereby rendering it invisible or black. John Michell extended…

Black Holes Every day we look out upon the night sky, wondering and dreaming of what lies beyond our planet. The universe that we live in is so diverse and unique, and it interests us to learn about all the variance that lies beyond our grasp. Within this marvel of wonders, our universe holds a mystery that is very difficult to understand because of the complications that arise when trying to examine and explore the principles of space. That mystery happens to be that of the ever elusive, black…

The Existence of Black Holes I have always had an interest in science, especially in the sciences regarding outer space. When I was younger I was always fascinated with rockets, and especially in stars. I have often regretted not pursuing this interest at its infancy. I do remember going to the Planetarium, and studying about a topic that I had seen talked about on television. The topic was black holes, and back then all that they knew was that they were black. The idea of a space in the universe…

Black Holes Every day we look into the night sky, wondering and dreaming what lies beyond our galaxy. Within our galaxy alone, there are millions upon millions of stars. This may be why it interests us to learn about all that we cannot see. Humans have known the existence of stars since they have had eyes, and see them as white glowing specks in the sky. The mystery lies beyond the white glowing specks we see but, in the things we cannot see in the night sky such as black holes. Before…

Black Holes Within our galaxy alone, there are millions upon millions of stars. Within our universe, there are millions upon millions of galaxies. Humans have known the existance of stars since they have had eyes. Although interpretations may have differed on what they were, they were always thought of as white glowing specks in the sky, but the mystery does not lie within what we can see, but what we can not see. There are billions of stars lighting the darkness of our universe, but the question…

Below you will read research on stars and black holes. Black holes are stars whose core has been crushed by gravity. In the text to follow you will see how a star forms, read about its life and how it becomes a black hole. Stars are composed of hydrogen gas and dust. Stars owe their existence to the force of gravity. Stars are created from the thinly spread atoms of dust and gas that swirl throughout space. The atoms clump together into dense clouds that eventually collapse under their own…

it can do many different things. It can form a neutron star, expand to a red giant and shrink into a white dwarf, or sometimes collapse upon itself to form a black hole. This is mostly dependent on the density of the star. When massive stars, those twenty times the mass of our Sun or more die, they must either exhaust all of their excess mass or implode upon themselves and form black holes. Gravity overwhelms even the nuclear forces. The gravitational force becomes so strong that nothing can escape…
