In fact, the Theory of Relativity deduces these discrepancies precisely on the basis of the assumption, that the speed of light is constant.

>Baffling or not, this is what is observed in several experiments, starting with the Michelson-Morley experiment, around the turn of the century (18th. to 19th. century, that is).

Hilmar, from what I have read the speed of light appears as a constant because the tools used to measure the speed of light, eg a clock and a fixed ruler, change with motion. As you approach the speed of light your clock slows down and your ruler shortens so the speed of light appears to be constant. The relationship between the measuring ruler and time for each observer however remains constant.
