Recommended: Physics behind black holes

Scientists are still trying to debate if black holes are real or not. Black holes also eventually evaporate. Thesis: Black holes are collapsed stars with a strong gravitational pull and they still stump scientists with all of their mysteries. II. Body Paragraph 1: How do Black Holes Form? Transition: First, State your point: How do they form Support your point: They form when a star collapse on itself. It causes a supernova which is a exploding star. Black holes have a strong gravitational forces that not even light can escape. The smallest black holes are known as primordial black holes. Scientists believe this black hole is as small as a single atom but with the mass of a large mountain Lead: Can black holes move and how do they affect the …show more content…

They believe that it is the biggest black hole known to scientists to this day. You can not see black holes with the naked eye of with a telescope. We wouldn't even know if black holes existed if we didn't have thermal telescopes or telescopes. With thermal pictures it shows that black holes horizon line event horizon and central parts. With a telescope you can see little disturbances in space which means there is a black hole there. Lead: Can black holes die IV. Can black holes die Transition: next, State your point: Can black holes die and how do they affect the space around them. Support: The event horizon glows then the energy carried away by the glow decreases the black hole's mass until it is completely gone. One of the other theories is that it gets destroyed the same way that it it is formed. Except after the supernova there is nothing left. The black hole has extreme amounts of radiation and heat and gravity. The black holes strong gravitational pull of a black hole affects all matter that falls in its path. Anything that falls into its path will be vaporized by the black hole. V. Are black holes invincible Can they stop eating or do they have a capacity Last, State your point: Are black holes invincible Can they stop eating or do they have a

    The particles escapes as Hawking Radiation. On the other hand, the anti particle gets sucked into the black hole. Since the anti particle has a negative mass, it actually decreases the mass of the black hole. The effects of Hawking radiation are generally negated by the fact that black hole sucks more in than it radiates (SST). But eventually it will not have anything more to suck in and start to lose mass.

    Starting with black holes, Khalili describes the creation of one. I found that a black hole is what remains when a massive star dies. Because stars are so massive and made out of gas, there is an intense gravitational field that is always trying to collapse the star. As the star dies, the nuclear fusion reactions stop because the fuel for these reactions gets burned up. At the same time, the star's gravity pulls material inward and compresses the core. As the core compresses, it heats up and eventually creates a supernova explosion in which the material and radiation blasts out into space. What remains is the highly compressed and extremely massive core. The core's gravity is so strong that even light cannot escape. This object is now a black hole and literally cannot be seen because of the absence of light. Because the core's gravity is so strong, the core sinks through the fabric of space-time, creating a hole in space-time. The core becomes the central part of the black hole called the singularity. The opening of the hole is called the event horizon. Khalili describes that there are two different kinds of black holes:

Scientists believe it is possible that at the very center there was too much matter to form an ordinary star, or that the stars which did form were so close to each other that they coalesced to form a black hole. It is argued that really massive black holes, equivalent to a hundred million stars like the Sun, could exist at the center of some galaxies

    A Black Hole is defined as an object in space that is so compact, that has a gravitational pull so powerful, not even light can escape its pull. In most cases Black Holes are formed when a massive star (much larger than our own) undergoes a supernova explosion. When this happens, the star may collapse on its own gravitational pull, thus resulting in a an object with infinitely large density and zero volume. As a result, the escape velocity (the speed required to escape the gravitational pull) becomes even greater than the speed of light, and because nothing can travel faster than the speed of light, nothing can escape a black hole.

    Before I begin to speak about black holes, I will have to explain what the white glowing specks in the sky are. Without a star a black hole could not be formed. In the beginning of a star life a hydrogen is a major part of its development. Stars form from the condensation of clouds of gas that contain hydrogen. Then atoms of the cloud are pulled together by gravity. The energy produced from the cloud is so great when it first collides, that a nuclear reaction occurs. The gasses within the star starts to burn continuously. The hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as carbon, oxygen, and helium are consumed. This chain reaction of explosions fuels the star for millions or billions of years depending on the amount of gases there are.

    Stars form by starting in a nebula, which is a cloud of interstellar hydrogen gas and dust and are born in cold, and dense clouds of gas which the pressure cannot resist gravitational contraction. The gas and dust compress due to gravitational forces, forming a slowly rotating globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and by shock waves of pressure from supernova or the hot gas released from nearby stars. These forces cause the roughly spherical globule to collapse and rotate and take a process of collapse from between 10,000 to 1,000,000 years. Gravitational forces overcome gas pressure and the globule collapses and the cooling occurs and its spin increases.

    Black holes are the result of the death of a massive star, leaving behind a dense remnant core that eventually collapses to create a gravitational force so strong that nothing, including light, can escape the force. The theory that black holes existed started back in the early 1900s and since then astronomers and scientists have been trying to get a better understanding of them. This phenomenon has been a working progress for astronomers and scientists for many years and as we develop a better understanding of our solar system, the more likely it is to make a significant discovery that can answer some of the most difficult questions about our incredible galaxy and solar system. The more information we are able to acquire about our universe, the more questions we might be able to answer about our existence. With advancements in technology we may be able to see some significant discoveries and insights into the world of black holes.
