## Length contraction does not occur

On February - 1 - 2009

In the model of Complete and Incomplete Coordinate Systems, length contraction does not occur.

## The Twin Paradox Goes Away

On February - 1 - 2009

In order to understand why the twin paradox goes away, I first have to highlight a point of confusion with Einstein’s transformation equations. In the model of Complete and Incomplete Coordinate Systems, there are four time equations; one for the time to travel along each of the 3 axes, and one for the amount of time that the coordinate system has been in motion.

## This model applies to all types of waves

On February - 1 - 2009

In the model of Complete and Incomplete Coordinate Systems, the velocity of the wave is represented by the value w. This variable can take on any value to represent the velocity of wave and medium under consideration. For example, when considering light waves traveling through a vacuum, we replace w with the value 299,792,458 meters per second, or by convention c. When considering light through air, its velocity decreases with increased density. In this case, we would first compute the new velocity and replace w with that value.

## The speed of light is constant, but can vary by coordinate system

On February - 1 - 2009

In the model of Complete and Incomplete Coordinate Systems, the behavior of the phenomena is determined by the characteristics of the coordinate systems.

Consider three different types of coordinate system “spaces”;
