Spacetime
The concept of space and time as a four dimensional continuum, spacetime, is fundamental to Einstein's relativity. However, the mechanics of spacetime seem to be little understood outside the scientific community.
It's not simply a matter of incorporating time as a dimension equivalent to the three spatial ones. It is more complex than that.
So this section explains Spacetime Mechanics, 3D Diagrams, Zero Intervals and Proper Time. A thought experiment called the Two Towers illustrates the problems in interpreting the effects of viewing an event from different spacetime view points. Then we consider Spacetime & Reality.
A more technical introduction to spacetime may be found here.
