  • General Relativity - 349 Words
    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...

  • General Theory of Relativity - 374 Words
    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...

  • General Theory of Relativity - 1667 Words
    General Theory of Relativity 1). Background General Relativity is a theory of gravitation developed and published by Albert Einstein in 1916. Once when Einstein was preparing for a review of his theory of relativity, he thought about the fact that a man falling from the roof of a building doesn't feel his own weight. This idea, which he called "The happiest thought of my life", (Brian Greene, The fabric of the Cosmos) was the reason that led Einstein to develop the theory of General...

  • 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...

  • 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....

  • 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...

    Einstein’s Theory of Relativity Albert Einstein was born on March 14, 1879 in Ulm, Germany. As Albert grew up he loved taking lessons on the piano and the violin. Then when he was about ten or eleven he grew the curiosity about mysteries of science. As he grew up into an adult he worked as a patent clerk in Bern, Switzerland. This is when Mr. Einstein published four of his research papers, one of them being the Special Theory of Relativity or as most people know it as E=MC². By 1915, Albert...

    In November of 1919, at the age of 40, Albert 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...

    In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.

It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. Granted, the slowing had not been observed, but, theoretically, the Universe had to slow. The Universe is full of matter and the attractive force of gravity pulls all matter...

    What is gravity? Gravity is a force pulling together all matter (which is anything you can physically touch). The more matter, the more gravity, so things that have a lot of matter such as planets and moons and stars pull more strongly. Mass is how we measure the amount of matter in something. The more massive something is, the more of a gravitational pull it exerts. As we walk on the surface of the Earth, it pulls on us, and we pull back. But since the Earth is so much more massive than we...

This idea held steady for 2,000 years, until Isaac Newton in a triumph of brilliance declared that there is one law of physics that governs motion and he unified “earthly” bodies and “heavenly” bodies with the The...

  • Exploring the Virtual Reality Conjecture by Brian Whitworth
    Exploring the virtual reality conjecture Brian Whitworth Introduction Computers today simulate entire worlds, with their own time, space and objects, but that our world could be so is normally a topic of science fiction, not physics. Yet that the world is illusory has a long history. In Buddhism, the world expresses the Universal Mind, in Hinduism it is Maya, the illusion of "God’s play”, and to Plato it was just shadows flickering on a wall1.

    Freefall and Projectile Motion Introduction and Objectives This lab experiment was done to determine the characteristics of free fall and projectile motion in Physics. The motion in which a body is thrown or projected is called Projectile motion while free fall is any motion of a body where gravity is the only force acting upon it, at least initially. In this experiment, a photogate, a chopper, and a Universal Lab Interface were used to determine the free fall motion of the chopper as it...

    In Newtonian physics, free fall is any motion of a body where its weight is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and it moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain. An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards...

    Acceleration Due to Gravity Have you ever wondered why items always speed up when they are falling? Well it all has to do with acceleration due to gravity. Acceleration is the rate at which an object changes its velocity. Acceleration can be calculated by finding the change in velocity and dividing it over the time. The equation is: a= ∆v∆t (“Acceleration”) Acceleration is also a vector because it has a direction. The units of acceleration are typically m/s2. Gravity is the force that attracts...
