**Relativity without Space-Time** — •Albrecht Giese — Taxusweg 15, 22605 Hamburg

Einstein developed relativity on the basis that the speed of light c is a true constant in any system, and he deliberately abstained from assuming the existence of an ether. Einstein paid a high price for this as he had to introduce (curved) 4-dimensional space-time to overcome logical conflicts.

Relativity (SRT and GRT) can be developed by assuming a fixed reference system (as an abstraction of an ether) and using known physical causes of contraction, dilation, the - measured - constancy of 'c' and the curvature of light rays. The resulting mathematical theory produces exactly the same results as Einstein. However, it only needs standard mathematics and is thus easy enough to be taught at school. In addition, unresolved problems like dark energy and quantum gravity can be solved.

There is a common misconception about the origin of relativity. This is the erroneous assumption that the Michelson-Morley experiment disproved the existence of an ether. Even Einstein did not draw this conclusion. It was Einstein's relation to the philosophy of positivism in his early years that made him dispense with an ether as a non-visible phenomenon (ref. Karl Popper).
