Albert Einstein's Theory of Relativity In Words of Four Letters or Less So, have a seat. Put your feet up. This may take some time. Can I get you some tea? Earl Grey? You got it. Okay. How do I want to do this? He did so much. It's hard to just dive in. You know? You pick a spot to go from, but soon you have to back up and and go over this or that item, and you get done with that only to see that you have to back up some more. So if you feel like I'm off to the side of the tale half the time, well, this is why. Just bear with me, and we'll get to the end in good time. Okay? Okay. Let's see.... [ I ] Say you woke up one day and your bed was gone. Your room, too. Gone. It's all gone. You wake up in an inky void. Not even a star. Okay, yes, it's a dumb idea, but just go with it. Now say you want to know if you move or not. Are you held fast in one spot? Or do you, say, list off to the left some? What I want to ask you is: Can you find out? Hell no. You can see that, sure. You don't need me to tell you. To move, you have to move to or away from ... well, from what? You'd have to say that you don't even get to use a word like "move" when you are the only body in that void. Sure. Okay.

RELATIVITY AND FTL TRAVEL The "Relativity and FTL Travel" FAQ was created mainly for the rec.arts.startrek.tech newsgroup. Much of it contains solid information about relativity (written mainly for the lay-person), while one important part discusses why relativity tends to forbid faster than light travel. It explains why no fictional and/or theoretical idea for FTL Travel can itself get around both the problems discussed without "special provisions". The "Introduction to the FAQ" will give much more information about the FAQ and its various parts. Be sure to check it out so you can decide which parts of the FAQ you might actually want to read/download. If you are interested in other information concerning relativity, be sure to check out the

Select the photographs to display the original source in another window. Newton's laws of motion work very well for anything moving at much less than the speed of light. His law of gravity works very well for any place of weak gravity such as in the solar system. Spacecraft sent to the distant planets in the solar system arrive at their intended destinations (barring mechanical problems) within a few minutes of the expected time even after travelling for billions of kilometers over several years time. The scientists use Newton's laws to guide the spacecraft to its destination. In this chapter you will see what happens when you look at things moving very fast (at a significant fraction of the speed of light) and you will see that space and time can be radically changed in a very strong gravitational field. In fact, you will find that gravity is not really a force! This revolutionary leap in our understanding of gravity and the nature of space and time was made by Albert Einstein (lived 18791955). In the first two decades of the 20th century, Einstein laid out a new paradigm of gravity and motion in space and time. In this chapter you will explore his

For example, people on Star Trek are always talking about the space-time continuum, worm holes, time dilations and all sorts of other things that are based on the principle of relativity in one way or another. If you are a fan of science you know that relativity plays a big part there as well, especially when talking about things like black holes and astrophysics.

New? Register Now! Already a member? Log In Friday February 8, 2008 What is Relativity? Friday February 8, 2008 Albert Einstein was famous for many things, but his greatest brainchild is the theory of relativity. It forever changed our understanding of space and time. What is relativity? Succinctly put, it is the notion that the laws of physics are the same everywhere. We here on Earth obey the same laws of light and gravity as someone in a far off corner of the universe. The universality of physics means that history is provincial. Different viewers will see the timing and spacing of events differently. What for us is a million years may just be a blink of an eye for someone flying in a high speed rocket or falling into a black hole. Special relativity Special relativity came first and is based on the speed of light being constant for everyone. That may seem simple enough, but it has far-reaching consequences. Einstein came to this conclusion in 1905 after experimental evidence This result was surprising to physicists because the speed of most other things does depend on what direction the observer is moving. If you drive your car alongside a railroad track, a train coming at you will seem to be moving much faster than if you turned around and followed it in the same direction. Einstein said that all observers will measure the speed of light to be 186,000 miles per second, no matter how fast and what direction they are moving.

Center for Relativity Home openGR Seminars ... Old Webpage UT Center for Relativity Researchers in the Center for Relativity are involved in the study of gravitation in both the classical and quantum regimes. The main emphasis in the group is on astrophysical applications of General Relativity (GR), using computers to simulate binary black holes and other relativistic objects. One principal goal of this work is to accurately model sources of gravitational waves, to eventually provide "template" waveforms for use in the data analysis of signals measured at observatories like LIGO. Interpreting these signals provides insight into the earliest epochs of the universe, and the deepest parts compact objects, available to any observational technique. We make use of substantial computing resources both at UT and around the country, and many purely computational problems are worthy of pursuit within the context of our group's research. Students interested in computational physics and/or astrophysics are particularly encouraged to participate. In addition to numerical studies, students in the group are investigating the structure of Einstein's (10 coupled, nonlinear partial differential) equations from a purely mathematical standpoint as well, including questions about constraint propagation and boundary conditions which are at the forefront of research in the field.

Introduction to General Relativity Problems with Newtonian Gravity Newton was fully aware of the conceptual difficulties of his action-at-a-distance theory of gravity. In a letter to Richard Bentley Newton wrote: It is inconceivable, that inanimate brute matter should, without the mediation of something else, which is not material, operate upon, and affect other matter without mutual contact; as it must do, if gravitation, ...., be essential and inherent in it. And this is one reason, why I desired you would not ascribe innate gravity to me. That gravity should be innate, inherent, and essential to matter, so that one body may act upon another, at a distance through vacuum, without the mediation of anything else, by and through their action and force may be conveyed from one to another, is to me so great an absurdity, that I believe no man who has in philosophical matters a competent faculty of thinking, can ever fall into it." So, clearly, Newton believed that something had to convey gravitational influence from one body to another. When later it became clear that influences travel at finite speeds it was reasonable to suppose this true of gravity also. But Newton's law of gravity did not incorporate the finite travel time of gravitational influences. If right now the sun were to be destroyed by a passing black hole we would not feel the gravitational effects until about 8 minutes had elapsed. Because Newton's law did not include such retardation effects, and permitted violations of special relativity, it was clear that Newton's law had to be an approximation to the correct law of gravity.
