EPJ Plus Focus Point: Tests of General Relativity and Alternative Gravity Theories

Testing of fundamental physical theories at ever higher accuracy is a continuous process and hence General Relativity and the development of alternative gravity theories have always been among the interests of experimentalists, astronomers and theoreticians. The empirical basis of General Relativity is linked to an immense scope of areas, from the equivalence principle up to the variation of the gravitational constant and of other physical constants.

A new phase of studies on extensions of General Relativity and alternative gravity theories started with the discovery of the dark sector - the dark energy and dark matter - as of dominating content of the Universe.

The papers included in this Focus Point although cover a minor fraction of the above mentioned areas, nevertheless they contain timely accounts on broad topics, from tests on equivalence principle, to orbital dynamics of extended bodies in inspiraling binary systems, up to cosmology.

All articles are available here and are freely accessible until 24 August 2019. For further information read the Editorial.
