    Simultaneity Help

    Introduction There are two aspects to Albert Einstein’s relativity theory: the special theory and the general theory . The special theory involves relative motion, and the general theory involves acceleration and gravitation. However, ...

    Time Dilation Help

    Introduction The relative location of an observer in space affects the relative readings of clocks located at different points. Similarly, relative motion in space affects the apparent rate at which time “flows.” Isaac Newton hypothesized that ...

    Spatial Distortion Help

    Introduction Relativistic speeds—that is, speeds high enough to cause significant time dilation—cause objects to appear foreshortened in the direction of their motion. As with time dilation, relativistic spatial distortion occurs only from the ...

    Mass Distortion Help

    Introduction Another interesting effect of relativistic speeds is an increase in the masses of objects as they move faster and faster. This increase occurs to the same extent as the decrease in length and the slowing down of time. Point Of ...

    General Relativity Help

    Introduction There is no absolute standard for location in the universe, nor is there an absolute standard for velocity. Another way of saying this is that any reference frame is just as valid as any other as long as acceleration does not take place. The notions ...

    Time in Relativity Help

    No Absolute Time One of the first results of Einstein’s speed-of-light axiom is the fact that there can be no such thing as an absolute time standard. It is impossible to synchronize the clocks of two observers so that they will see both ...

    Curvature of Space Help

    Spatial Curvation Imagine that you are in a space ship traveling through deep space. The ship’s rockets are fired, and the vessel accelerates at an extreme rate. Suppose that the laser apparatus described earlier in this chapter is in the ship, but instead ...

    Time Dilation by Gravitation Help

    Time Dilation by Gravitation The spatial curvature caused by intense acceleration or gravitation produces an effective slowing down of time. Remember the fundamental axiom of special relativity: The speed of light is constant, no matter what the point of view. The ...

    Observational Confirmation of General Relativity Help

    Observational Confirmation of General Relativity When Einstein developed his general theory of relativity, some of the paradoxes inherent in special relativity were resolved. (These paradoxes have been avoided here because discussing them would only confuse you.) ...
