    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. Scientists do not have the ability to directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. However

  • What Is A Black Hole?

    What is a black hole? In simple terms, a black hole is a visually undetectable region of space that exerts a gravitational force so powerful that not even light can escape [Wald 1984, pp. 299–300], thus exhibiting the characteristics of an ideal black body in the sense that it absorbs all the radiation that falls on it [Schutz, Bernard F. (2003). Gravity from the ground up. Cambridge University Press. p. 110]. In addition, all black holes are enveloped by spherical “boundaries” known as “event horizons”

    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

    Are all black holes the same? Introduction Once confined to science fiction and a mere mathematical prediction in general relativity by Einstein in 1916 (although he didn’t believe they were possible) and still believed theoretical only 30 years ago, black holes are now believed to be in among the millions within the Universe. Furthermore latest research predicts there is one in the centre of most

    Black Holes 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

    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: Introduction: 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

    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

    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 it, even photons of light, hence the name "black" hole. It is believed that large black holes may exist at the center of our

    Black holes are celestial bodies so dense and strong that nothing can escape their pull. The idea of black holes is generally referred to the French mathematician, Pierre Simon Laplace. In 1796, Laplace who was studying the subject of escape velocity; this is the speed that something must be accelerated to in order to prevent being pulled back by the gravity of a larger body. For example, to escape the Earth’s gravitational pull we must accelerate our rockets to over 11 kilometers per second. If
