Is the Speed of Light ’c’ a True Constant? — •Albrecht Giese — Taxusweg 15, 22605 Hamburg

Einstein has - in his structure-based theory of relativity - stated that the speed of light ’c’ is a true constant under all circumstances. He has concluded this from the Michelson-Morley experiment, not realizing that this experiment only demonstrates the 2-way speed of light.

Philosopher Hans Reichenbach, a prominent supporter of Einstein, has pointed out that Einstein’s conclusion is logically not compelling. The 1-way speed of light is not proven to be constant, and relativity can be explained in different ways.

The poster presentation will point out that:

1. The apparent constancy of ’c’ is a measuring effect caused by the contraction of rods and the slow down of clocks, which both can be physically explained

2. The curvature of space-time in a gravitational field can be replaced by the slow down of ’c’ in the field and the resulting refraction of light-like objects

3. The change of ’c’ during the development of the universe is a physically better replacement for the so called ’inflation’. Furthermore it avoids the necessity of a ’dark energy’. Additionally it allows for an adapting change of basic physical parameters and in this way makes the landscape of 10¹⁰⁰ universes superfluous.
