Good morning 10F and Dr Guppy‚ I 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

“The distinction between the past‚ present and future is only an illusion‚ however persistent.” –Albert Einstein These days‚ even respected physicists like Stephen Hawking are being forced to admit that time travel may be possible. But has it already happened? These people say it has. Father Pellegrino Ernetti was a Benedictine monk and respected authority on archaic music. He also claimed to have co-invented—as part of a team that included Nobel Prize-winning physicist Enrico Fermi and German rocket

Description: This chapter chronicles the works of Albert Einstein‚ predominantly his dual theories of Special Relativity and General Relativity. Special Relativity involves time‚ which was established as subjective and relative to the object in question. He also worked to establish the consistency of the speed of light as a daunting measure which cannot be surpassed (E=MC2). His General Theory of Relativity pushed forth the idea that space and time were not independent‚ but rather connected in some fabric

Descartes proof‚ which states that since he can think he must exist‚ is flawed in the sense that it follows the assumption that some things are absolute. As seen in both Nietzsche’s and Merleau-Ponty’s books‚ nothing is absolute. They stated that everything was in perspective‚ and that humanity needed to study what is closer to them‚ whether it was psychology or phenomenology. The only things Descartes figured out were that he had a reason to doubt and that math and science could help him understand

relationship between energy and mass” (Pakhare). Einstein was also credited and recognized for the creation of the atomic bomb‚ and not only that but his theory of relativity. One amazing statement said about Einstein was that he had been called “the father of the atomic bomb” (Pakhare). There has been many fascinating facts that most of the general public do not know about Einstein‚ for example he quit high school at the age of 15‚ he loved to sail‚

April 2005 Physics Honors Stephen Hawking Stephen Hawking was born on January 8‚ 1942. He is the first child of Frank and Isabel Hawking. During the second World War‚ Isabel was sent from her husband’s home in Highgate‚ to Oxford. This was considered a much safer place to have children during the war. Soon after his birth‚ his family moved back in together in their north London home. Hawking began his schooling here at Hertfordshire School. Hawking moved only once during his

Rodrigues Ms. Scanlon Physical Science 28 March 2013 Time Travel and How Black Holes make it Possible “Man… can go up against gravitation in a balloon‚ and why should he not hope that ultimately he may be able to stop or accelerate his drift along the Time-Dimension or even turn about and travel the other way” (Wells). In this quote‚ H.G. Wells asked one of the most commonly asked questions in time travel‚ why can people not move about in time as they wish? Black Holes present the
