blast off from this world to see how close we can really get to a black hole; while we are out in the vacuum of space‚ we will research and analyze what Black holes really are‚ and finally we will return back to earth and see how these findings affect us. Transition: We will start off by leaving our world behind and going to search for these invisible monsters. Body: Point 1.) Now‚ what’s does the Federal Deficit and a Black Hole have in common? They both never end because According to the National

will be speaking about an astronomical phenomenon called black holes. A black hole is an area of space-time. Rather‚ it is a great amount of matter packed into a very small region it is also the last evolutionary stage in the lifetimes of vast stars. This makes the black hole invisible to the rest of the universe‚ hence the word "black". A star‚ about 20 times the mass of the sun may produce a black hole at the end of its life. A black hole is formed by nuclear reactions in the core of a star producing

A black hole is an object with such a strong gravitational field that even light cannot escape from its surface. A black hole may be formed when a massive object (very big object) undergoes uncontrolled contraction (a collapse) because of the inward pull of its own gravity. We shall now describe how the black holes are formed from neutron stars after the supernova explosions of big stars. When a supernova explosion of a very massive star takes place‚ then the gaseous matter present in the outer shell

The universe is full of vast objects‚ and quite possibly not all have been discovered. Black holes are among one of these that have been discovered and began to take a life of their own. Hollywood has depicted them as a space time traveling device. The truth of the matter is though if you were to be “sucked” into one you would never be able to escape and you would die. A black hole is caused when a red super giant star begins to run out of fuel. The star loses the force pushing itself outward

This essay will explain what a black hole is along with how black holes can be detected and how black holes are formed. Moreover‚ this essay will also provide evidence of the existence of black holes and locate where in the universe black holes occur. Firstly‚ a black hole is seen as a body in space whereby a strong gravitational pull causes a suction to be formed. The strength of the gravitational pull is so significant due to the different forms of matter being squeezed into a small hole which

Black Hole Talking about the universe is always a mysterious subject for us. There are lots of theories about the universe by different scientist. Nobody actually knows the reality. Like the universe the topic‚” Black Hole”‚ is also mysterious. We know what black hole is but we are not able to give the detail information about it. As everybody says that‚” black hole is a region in space that has an indefinite density and the gravitational force that does not let anything escape from its influence

INTO A BLACK HOLE INTRODUCTION: According to a mind-bending new theory‚ a black hole is actually a tunnel between universes—a type of wormhole. The matter the black hole attracts doesn’t collapse into a single point‚ as has been predicted‚ but rather gushes out a "white hole" at the other end of the black one‚ the theory goes. In a recent paper published in the journal Physics Letters B‚ Indiana University physicist Nikodem Poplawski presents new mathematical models of the spiralling motion of

Black holes are some of the most fascinating and mysterious parts of space. It has so much gravitational pull that nothing can escape from it‚ even light if it gets close enough. Albert Einstein predicted black holes back in 1916. The term “black hole” was made up in 1967 by an American astronomer John Wheeler. The first black hole was discovered in 1971 by rockets that were carrying Geiger counters that came across eight new x-ray sources. Scientists that detected radio signals coming from it found

Black holes are the most mysterious objects that modern physics predicted. Event horizon is the edge of the black hole. If anybody attempts to cross the black hole he or she will never come back. The holes are involved in a broad range of astrophysical occurrence‚ including majority of the active events in the space. John Michelle‚ a British mathematician‚ initially visualized black holes in 1783. He called them dark stars and his explanation was based on Newton’s laws of gravity. Employing Newton’s

Black holes are one of the most fascinating and unrealistic seeming objects in the world to many people. They seem to be right out of a science fiction novel‚ along with white holes‚ and wormholes. So far white holes and wormholes are still only science fiction. A white hole is a reverse of a black hole. And a wormhole is a combination of a white a black hole said to be a place of time travel. However‚ even quite a long time ago some members of our society realized that the black hole is not science
