When objects move at relativistic speeds, some strange things happen. This is an attempt to explain some of the geometric distortions that occur.

A complete description of relativistic effects includes the following:

(These links are included for convenience. For the complete tour, click on the explanation link below.)

- Length dilation (due to Lorentz contraction)
- Terrell rotation
- Lines perpendicular to motion are curved and the aberration of solid angle
- Doppler shift
- Time dilation

Brief History of the discovery of relativistic effects.

I have tried to make these pages viewable in text based browsers; the text acting to explain the pictures throughly. However, I believe that in most cases, the pictures are still necessary.
