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. The physical community has accepted this up to now in spite of the problems arising from this paradigm; see the deadlock situation of present physics (Quantum Gravity).

The constancy of the speed of light has 3 aspects:

1.) Is 'c' the same for an observer in motion or at rest?

Einstein says: YES - Lorentz says NO; only the measured 'c' is constant resulting from the contraction of measuring rods and the de-synchronization of clocks during motion.

2.) Is 'c' the same inside and outside a gravitational field?

Einstein says: YES - We can say: NO; 'c' is reduced in a grav. field, and not the space is curved but fields are; gravity is not force # 4 but a side effect of other forces

3.) Was 'c' a constant during the development of the universe?

Einstein says: YES - Magueijo says: NO; if we accept an (adapting) decrease of 'c', we can avoid the inflation in cosmology and the landscape of 10**100 universes.

The remarkable point of the alternative approaches mentioned above is that they yield the same mathematical results as the traditional version of Einstein, to the extent as they are confirmed by observations and experiments.
