What happens to radio waves, time, and light in and near a black hole? Young scientists explore what is known about observing frequency and time at various distances from a black hole. They control the size of the black hole and the...

Students calculate distance, velocity, acceleration and time on their fantasy trip to the black hold. They apply Newton's Laws of Motion and calculate circular motion. They discuss any questions that may arise.

Students read first hand accounts of earthquake survivors in order to begin the describe the different types of earthquake waves and the order in which they arrive. They engage in using earthquake waves as a means to indirectly study the...

This model permits manipulation of variables in order to observe the effects of time dilation on twin objects, one moving and one not, as shown in a spacetime diagram.

College-level electrical physics course highlighting Einstein's Special Theory of Relativity. Course introduces the physics of Lorentz contraction, time dilation, the "twin paradox", and E=mc2. Course features suggested readings,...

If the speed of light remains a constant then time and distance change. Oh, it can be confusing! This text will help clear up the confusion. Discussion questions should serve to reinforce comprehension.and exercises

Review your understanding of relativity with this study guide.

This site from the Georgia State University provides an interesting chart form of the ideas of relativity. Column 1 - Idea, Column 2 - Experiment. Each item is linked to its own page of explanation, which is well done. A nice type of...

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...

This page provides an incredibly detailed description of Albert Einstein's Special Theory of Relativity. Definitely an excellent website with great pictures and examples!

To make sense of this, you have to first see the Twin Paradox: Introduction, which is the special relativity version and is linked to this page. This general relativity explanation views the paradox from a gravitational point of view.
