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

At first glance, the Michelson-Morley experiment seems to suggest that 'c' is constant in relation to any system. However, at second glance this constancy turns out to be purely a result of the measuring procedure.

H. Lorentz pointed out that this apparent constancy is the result of well understood field behaviour. Einstein accepted this as a viable explanation, but disliked it because it made necessary an ether, which he didn't want. He insisted on a theory with a constant 'c' with respect to any system. To achieve this, he had to assume that space and time vary depending on the actual conditions of motion.

Einstein extended this principle about 'c' to gravitational fields. Even though it can be shown by direct measurement that 'c' is reduced in such a field, Einstein again asserted that it is constant and explained the result of the measurement through a change in space-time (which is not directly measurable).

It is logically possible to transform Einstein's equations, based on the constancy of 'c' and variable space-time, into a model in which space and time are fixed, as otherwise always assumed, but 'c' is variable. This results in a much simpler understanding of physics with predominantly similar results to those of Einstein.
