his/her eyes caught them. Light is the one particle that sheds luminosity over everything, and is the only way of seeing the elusive and magnificent nature of the universe. But to understand light is too understand its speed—a speed so great that nothing with mass can ever reach it. So what is the speed of light? It is 299, 792, 458 meters per second or 186,000 miles per second, but humans didn’t always know that light was this speed—at one point in time humans thought that light could travel any distance

How does light speed affect the universe? What about our everyday lives? In the History Channel documentary, “The Universe – Light Speed”, what light speed is and how it affects the universe helps explain how important it is for not only learning the history of our Solar System but the universe itself. How light speed affects stars we see from Earth, the significance of redshift, light horizon and how it affects our glimpse into space, and how ideas are being formulated to traverse space are key

at constant speeds relative to each other. He explained that when two objects are moving at a constant speed as the relative motion between the two objects, instead of appealing to the other as an absolute frame of reference that defined what was going on. Einstein’s theory is based on two things: the principle of relativity and the principle of the speed of light. The principle of relativity is where the laws of physics don’t change, even for objects moving in inertial (constant speed). The principle

T I M E “Time, what time is it? Is it time for class already? No, we still have some time.” It is time that we have totally forgotten about, and have taken it for granted for so long. But does time really exist? Does the 24 Hours of the day mean anything? Or does 12 months? Time means different things to different people. According to “COLLINS COBUILD Learner’s Dictionary” (©HarperCollins Publishers Ltd.1996) time is defined as ‘the measurement we measure in minutes, hours, days, and years.’ Seems

Informative Speech Scientists Einstein and Heisenberg A. Introduction My Speech is about the scientists who had the main influence on our current time and have shaped our contemporary view of the world (Also called in Theology the "Zeitgeist"). I have chosen two of them who were in many ways just opposites. One is extremely famous and the other is almost unknown except to specialists. The most famous is of course Albert Einstein. He has significantly altered our view of the world with his Theory

Einstein's Relativity, Literature and Perception The effect relativity had on literature was that it gave a new way of viewing objects moving at speeds near light. What a person sees depends on their viewpoint. Relativity states that as an object moves faster from a relatively stationary point the object becomes warped, or a plane that flies 'straight" over a merry-go-round would appear curved to the rider. These are two examples of the way relativity causes someone to think. The biggest direct

An aeroplane flies about 400-500 metres above the water at a speed of approximately 60 - 70 m/s. Then the aircraft will send out a pulse which is moderately reflected off the surface of the water and moderately broadcasted into the water and reflected off the oceans floor, as a result two pulses are sent back to the aircraft. The pulse which was reflected of the surface of the water is a red beam (infrared) which measures the aircraft height above the water and is directed vertically downward. The

such as yourself because special relativity explains the observed fact that the speed of light stays and remains constant regardless of the direction or velocity of its motion. Special relativity now plays an important role in astronomical observation. Special relativity is more precisely about speed. To be even more precisely this speed deals with 299,792,458 ms-1, which is the speed of light, or the rate at which light travels (in meters) per one second. This theory, developed by the greatest genius

could calculate relative speeds. Suppose that an observer stands on the side of the highway, and they watch two cars approach each other at 30 and 40 miles per hour. If they were to ask the question, "how fast is the 40 mile per hour car moving relative to the 30 mile per hour car?" They could solve the problem easily by adding the two speeds of the cars, which would equal 70 miles per hour. This means that the 40 mile per hour car sees the 30 mile per hour car advance at a speed of 70 miles per hour

travel back to see our founding fathers sign the declaration of independence. We could travel to 2999 to witness the birth of the next new millennium. Such travel would require a machine capable of withstanding great pressures and incredible amounts of speed. The act of actually traveling though time is for the most part, agreed upon, but the implications of such travel is not so decided upon. Many different theorists have different views of what could happen and some go, as far as to say that if we did
