General relativity

concepts consist of cheer leading. Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. Therefore, cheerleading involves the force of gravity, because of the stunts, the tumbling, and the jumps. Anything you drop accelerates at the same rate…

GRAVITATIONAL WAVES, HOW CLOSE ARE WE? PHSCS 222 Collective Paper November 23, 1999 #123 #272 #666 #895 The Detection of Gravitational Waves, How Close Are We? Since the realization that the general theory of relativity predicts gravitational waves, there have been attempts to actually detect these waves. Indirect observations have been made that support their existence but no direct measurement. This paper gives a brief explanation of gravitational waves and discusses the…

matter(Shelton). Dark matter cannot actually be seen or detected itself, but, as Zwicky found, it causes immense levels of gravity. This newly discovered galaxy has only the normal amount of gravity you would expect to find due to its stars, planets, and general cosmic junk, unlike every other galaxy we’ve researched, which has a much greater gravitational effect than can be attributed to the mass of the known matter in any particular galaxy. Jim Shelton quotes Pieter van Dokkum, the leader…

of this paper, is one of the most dangerous thing he meets. In this paper, I start with the history of studying black hole, then analyze its priorities and structure, and list some astronomical observation. Black holes, according to general theory of relativity,…

Plato once said, “Astronomy compels the soul to look upwards and leads us from this world into another.” Obviously, astronomy has always been an interest to mankind. We look up into the night sky and feel an urge, something pulling us towards the stars. Many people have been influential in discoveries involving the stars and the planets beyond. From Galileo Galilei to Stephen Hawking, we have learned and discovered amazing things about the universe, and in recent discoveries we have wondered if…

The Mystery of Black Holes with Scientific Understanding If the sun were to suddenly becoming a black hole, what would happen to us here on Earth? To many people’s surprise the factor that would kill our life forms on earth would be the loss of heat and light and not from getting sucked into the black hole. There is not complete evidence to support that black holes exist but there are many signs and scientific theories that support there existence. Black holes can be a mysterious subject but…

Articles of the same subject can have both simulators and differences. Such examples are seen between articles "The Blue-Collar eclipse" from the Atlantic magazine and an article from Times Higher Educational. The two articles are about the same subject yet their content is different One similarity between the two article the fascination Shown about astronomy. Astronomy is the study that deals with celestial objects in space The writer of the blue collar eclipse is a lover of astronomy not…

Eliza Revell Big Bang Theory Task-Science 2015 10CH For a very long time the Big Bang theory has been one of the most talked about topics in science. Most astronomers believe that the universe began with a ' Big Bang ' They believed that it happened about 14 billion years ago. At that point in time, astronomers think that the universe was inside a dense kind of 'bubble' that was thousands of times smaller than a pinhead. They think it was…
