[|Theory of Relativity - Factual Implications]

__**Overview:**__ A very simple single page article on Einsteins's Theory of Relativity. It Gives a brief history on the topic and also a general description on both of Einstein's Special and General Theories on Relativity. At the end of the article, the author goes on to explain how this concept supports the idea of creation. I can't attest to the validity or accuracy of this claim, however the basic information in reference to Einstein's theories and their applications are correct. __**Author:**__ Unknown __**Last Updated:**__ Unknown __**Date Reviewed:**__ Unknown __**Reviewed By:**__ Joseph Steiner __**Accuracy:**__ The information is very detailed about Einstein's theory.It gives a brief history of when he proposed it. __**Readability and Clarity:**__ The site is easy to read and clear about what the topic is although it is a little vague and gives only basic information. __**Ease of Navigation:**__ Only one page, no other navigation is needed.

__**Einstein's Theory**__

Theory Of General Relativity



__**Overview:**__ This page talks about Einstein's theory of General Relativity. It gives some basic history as to how Einstein came up with the theory and also talks a little bit about Isaac Newton's theory of gravity. It gives explanations and examples of things that are tied with Einstein's theory such as gravitational lensing, Mercury's Orbit, frame-dragging, gravitational redshift and gravitational waves. __**Author:**__ Nola Taylor Redd __**Last Updated:**__ Unknown **__Date Reviewed:__** 15 May 2013 __**Reviewed By:**__ Romel Magwili __**Accuracy:**__ The information on this site is similar to many other sources and are accurate as to what Einstein's theory of general relativity means and states. It also gave examples and evidence that support Einstein's Theory. __**Readability and Clarity:**__ The article can be a bit confusing for someone without any background knowledge of the discussed material. Many terms and large words are used that some may not be familiar with. Although it is a tough concept to grasp, the statements are stated clearly and someone with some knowledge about the subject will find the information useful. __**Ease of Navigation:**__ All of the information is in one page and all that's needed is some scrolling down.

Putting Relativity to the Test __**Overview:**__ This site presents events that Einstein's theory predicted and gathers experiments and observation that support the claims. It shows when and how these predictions were observed by many different people from the past. __**Author:**__ Unknown __**Last Updated:**__ 22 November 1995 __**Date Reviewed:**__ 15 May 2013 __**Reviewed By:**__ Romel Magwili __**Accuracy:**__ The website is a little outdated, it mentioned that gravitational waves has not yet been detected while in reality, our technology today actually allowed us to measure disturbances in space-time. __**Readability and Clarity:**__ The website is clear, understandable and to the point. It is easy to understand what it is saying even without any background knowledge. Someone who is interested in knowing when Einstein's theories were first observed would find this information very useful.

__**Visualizing the Theory of Relativity**__

[|Albert Einstein's Theory of Relativity] __**Overview:**__ This page is more so illustrative than informative. It would be a very good idea to take a look at the first link on this page before exploring this site. You need to have a base knowledge of Einstein's theory before you will would be able to fully understand what is happening to the right and the additional examples that can be found on this site. __**Author:**__ Unknown
