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

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 hence‚ creates

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

whether you believe or not” (Sachar 41). The book I read was Holes by Louis Sachar. This book is about a boy‚ named Stanley Yelnats‚ who is ‘cursed’ with bad luck. The ‘curse’ started with Stanley’s no-good pig stealing great great grandfather. During the early parts of the story‚ Stanley is arrested and sent to Camp Green Lake where boys go to ‘build character’. While at Camp Green Lake‚ the boy had to dig five foot by five-foot holes. They said this was to ‘build character’; however it was not

Have you ever heard of the book Holes? If you have not you are missing out on a great book! It is about a boy who has to serve an accused prison camp session…. But it turns into a whole lot more after a couple of days! This book is a fiction book because most of the things accomplished in this story are way too realistic to be performed in real life. One thing that is way too realistic is the fact you can eat only onions and live 200 years without eating anything else! Another thing that is too

talk about the ozone hole‚ I would like to talk about what ozone is. Ozone is a gas that is made of three oxygen atoms and it’s found up in the atmosphere (stratosphere layer). These three oxygen atoms are so important to us because they protect us from UV radiation. When UV rays try to come to earth they come across these three oxygen atoms and hits them‚ converting them into oxygen gas (O2) and one more oxygen (O). That prevents the UV rays from coming to earth. Ozone hole means that it’s an area

Macular holes are a hindrance for patients. They can cause massive vision loss‚ typically 20/200 or worse‚ that cannot be recovered.1 A patient who experience any vision loss can have an affect on person’s mental health and degrade their quality of life. The most common cause of macular holes is idiopathic‚ or unknown origins‚ however‚ there are signs of macular holes beginning to form that doctors can look out for.2‚3‚4 One of these etiologies is vitreomacular traction (VMT)‚ or pulling on the macula

You never quite understand yourself until you’re tested. The book "Holes" by Louis Sachar tells a story of Stanley Yelnats‚ who happened to be under a curse that began with his no-good-dirty-rotten-pig-stealing great-great-grandfather. Throughout the days in Camp Green Lake‚ he was able to discover the real history of his family. I enjoyed reading the adventures in this book even though the ending seems a bit unrealistic. In personal opinion‚ there were several different purposes of Louis Sachar
