Gravity Based on Lorentzian Relativity — •Albrecht Giese — Taxusweg 15, 22605 Hamburg

When relativity was introduced, around 1900, two fundamentally different approaches were under discussion. The earlier one was proposed by Lorentz / Larmor and based on physical processes: contraction was deduced from the known contraction of fields in motion, dilation from an assumed oscillation in particles with a velocity c. At the time, however, this approach was considered very speculative since the understanding of particles and matter was very sketchy and did not support this interpretation.

Einstein's approach, which assumed specific properties of the abstract notions of space and time and which was based on a principle rather on physical laws, was therefore more easily accepted.

In the meantime, though, the approach proposed by Lorentz / Larmor is fully supported by our knowledge of physics. Hence, not only can special relativity be based on known physics but so too can general relativity, i.e. gravity. If we use the known facts of the reduction of c in a gravitational field and the mentioned properties of elementary particles, all results and facts of relativistic gravity can be deduced by using Euclidian geometry and basic mathematics rather than principles.And the big open problems of dark matter and dark energy have solutions corresponding to a straightforward physical explanation.
