Description
Usually the space-time metric of General Relativity is defined through electromagnetic phenomena, namely the speed of light. Here we propose a gravity-only approach in the sense of a pre-metric theory of gravity. It is now gravity itself which defines the space-time metric. Through this appoach it is possible to introduce a gravitational metrological triangle made of gravitational permittivities and permeabilities as well as of the speed of gravity. This allows to include more existing high precision tests to the exploration of the nature of gravity. As a result it is possible to improve the determination of Solar System general relativistic effects.
