  • General Relativity

    General relativity is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915. According to general relativity‚ the observed gravitational attraction between masses results from their warping of space and time. By the beginning of the 20th century‚ Newton’s law of universal gravitation had been accepted for more than two hundred years as a valid description of the gravitational force between masses. In Newton’s model‚ gravity is the result of an attractive force between

  • General Theory of Relativity

    General relativity or the general theory of relativity is the geometric theory of gravitation published by Albert Einstein in 1915. It is the current description of gravitation in modern physics. It generalises special relativity and Newton’s law of universal gravitation‚ providing a unified description of gravity as a geometric property of space and time‚ or spacetime. In particular‚ the curvature of spacetime is directly related to the four-momentum (mass-energy and linear momentum) of whatever

  • The History of Classical Gravitational Theory and General Relativity

    The History of Classical Gravitational Theory and General Relativity In the beginning scientists and religious men of their era tried to explain the universe both biblically and scientifically. One of the foremost Greek scientists was Aristotle; taught by Plato‚ that the circle and sphere are the two most perfect shapes in a 2 and 3 dimensional universe‚ Aristotelian system placed Earth at the center of the universe; and all other heavenly bodies revolved around the earth in crystalline orbitals

  • Physics: General Relativity and 19th Century

    Physics  is a natural science that involves the study of matter and its motion through spacetime‚ as well as all related concepts‚ including energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics had been considered synonymous with philosophy‚ chemistry‚ and certain branches of mathematics and biology

  • Wormholes and Interstellar Travel: An Application of General Relativity

    Wormholes and Interstellar Travel: An Application of General Relativity In Einstein’s theory of general relativity‚ time and space are made dynamic and are curved by matter and energy. This has allowed physicists to dream up configurations that would allow travel to far distant places in the universe that were once made unattainable by the sheer distances and the natural speed limit of the universe; the speed of light. The theory has also opened up the possibility to travel through time. Like

  • A Qualitative Outline of General Relativity and Space-Time Curvature

    Outlining General Relativity and Space Time Curvature In the real world‚ smooth‚ uniform motion is more an exception than a rule. Technically‚ any change in speed or direction is called acceleration (or deceleration)‚ which can thus mean slowing down as well as speeding up‚ or simply a redirection. Ordinarily‚ an observer in an accelerating frame of reference can perceive its motion. Passengers in a car‚ for example‚ fell themselves pressed backward if the car starts suddenly from a dead stop

  • Essay On Einstein's Relativity

    Einstein’s Relativity Imagine if you got lost in a town‚ you would use a GPS to help you. But if Einstein never found out Relativity‚ then you would have a hard time finding your destination. Einstein’s Relativity changed the world because his equations and theories help make nuclear power plants and the GPS. Relativity is not only used in daily life‚ but also used extensively by aero-space-scientists. For example‚ The Precession of Mercury’s orbit can only be accurately predicted by Einstein’s Relativity

  • Albert Einstein - Relativity and the Cosmos

    Einstein became an overnight celebrity‚ thanks to a solar eclipse. An experiment had confirmed that light rays from distant stars were deflected by the gravity of the sun in just the amount he had predicted in his theory of gravity‚ General Relativity. General Relativity was the first major new theory of gravity since Isaac Newton’s‚ more than two hundred and fifty years earlier. Einstein became a hero‚ and the myth building began. Headlines appeared in newspapers all over the world. On November

  • The Theory Of Special Relativity, By Alexander Einstein

    Einstein published four papers‚ two of which were on The Photoelectric Effect and another on The Theory of Special Relativity (The latter being highly inspired by Maxwell’s work on electrodynamics). Special Relativity is basically the theory of

  • Einstein's Theory Of Special Relativity

    The biggest equation to come out of Einstein’s theory of special relativity is E = mc^2‚ which tells us how E‚ the energy‚ M‚ the mass‚ and C‚ the speed of light‚ are related to each other. This mass we are using is not the same as weight. An object’s mass is how much stuff is inside of it‚ while its weight is how hard gravity is pulling on it. This is why when you measure your weight in outer space‚ it is close to zero. Einstein’s theory states that‚ the speed of light becomes a sort of ultimate
